Medicare Program; Prospective Payment System for Long-Term Care 
Hospitals RY 2009: Proposed Annual Payment Rate Updates, Policy 
Changes, and Clarifications

AGENCY: Centers for Medicare & Medicaid Services (CMS), HHS.

ACTION: Proposed rule.

-----------------------------------------------------------------------

SUMMARY: This proposed rule would update the annual payment rates for 
the Medicare prospective payment system (PPS) for inpatient hospital 
services provided by long-term care hospitals (LTCHs). In addition, we 
are proposing to consolidate the annual July 1 update for payment rates 
and the October 1 update for Medicare severity long-term care diagnosis 
related group (MS-LTC-DRG) weights to a single fiscal year (FY) update.
    In this proposed rule, we are also clarifying various policy 
issues.
    This proposed rule would also describe our evaluation of the 
possible one-time adjustment to the Federal payment rate.

I. Background

A. Legislative and Regulatory Authority

    Section 123 of the Medicare, Medicaid, and SCHIP (State Children's 
Health Insurance Program) Balanced Budget Refinement Act of 1999 (BBRA) 
(Pub. L. 106-113) as amended by section 307(b) of the Medicare, 
Medicaid, and SCHIP Benefits Improvement and Protection Act of 2000 
(BIPA) (Pub. L. 106-554) provides for payment for both the operating 
and capital-related costs of hospital inpatient stays in long-term care 
hospitals (LTCHs) under Medicare Part A based on prospectively set 
rates. The Medicare prospective payment system (PPS) for LTCHs applies 
to hospitals described in section 1886(d)(1)(B)(iv) of the Social 
Security Act (the Act), effective for cost reporting periods beginning 
on or after October 1, 2002.
    Section 1886(d)(1)(B)(iv)(I) of the Act defines a LTCH as ``a 
hospital which has an average inpatient length of stay (as determined 
by the Secretary) of greater than 25 days.'' Section 
1886(d)(1)(B)(iv)(II) of the Act also provides an alternative 
definition of LTCHs: Specifically, a hospital that first received 
payment under section 1886(d) of the Act in 1986 and has an average 
inpatient length of stay (LOS) (as determined by the Secretary of 
Health and Human Services (the Secretary)) of greater than 20 days and 
has 80 percent or more of its annual Medicare inpatient discharges with 
a principal diagnosis that reflects a finding of neoplastic disease in 
the 12-month cost reporting period ending in fiscal year (FY) 1997.
    Section 123 of the BBRA requires the PPS for LTCHs to be a ``per 
discharge''

[[Page 5344]]

system with a diagnosis-related group (DRG) based patient 
classification system that reflects the differences in patient 
resources and costs in LTCHs.
    Section 307(b)(1) of the BIPA, among other things, mandates that 
the Secretary shall examine, and may provide for, adjustments to 
payments under the LTCH PPS, including adjustments to DRG weights, area 
wage adjustments, geographic reclassification, outliers, updates, and a 
disproportionate share adjustment.
    In the August 30, 2002 Federal Register, we issued a final rule 
that implemented the LTCH PPS authorized under BBRA and BIPA (67 FR 
55954). This system uses information from LTCH patient records to 
classify patients into distinct MS-long-term care diagnosis-related 
groups (MS-LTC-DRGs) based on clinical characteristics and expected 
resource needs. Payments are calculated for each MS-LTC-DRG and 
provisions are made for appropriate payment adjustments. Payment rates 
under the LTCH PPS are updated annually and published in the Federal 
Register.
    The LTCH PPS replaced the reasonable cost-based payment system 
under the Tax Equity and Fiscal Responsibility Act of 1982 (TEFRA) 
(Pub. L. 97-248) for payments for inpatient services provided by a LTCH 
with a cost reporting period beginning on or after October 1, 2002. 
(The regulations implementing the TEFRA reasonable cost-based payment 
provisions are located at 42 CFR part 413.) With the implementation of 
the PPS for acute care hospitals authorized by the Social Security 
Amendments of 1983 (Pub. L. 98-21), which added section 1886(d) to the 
Act, certain hospitals, including LTCHs, were excluded from the PPS for 
acute care hospitals and were paid their reasonable costs for inpatient 
services subject to a per discharge limitation or target amount under 
the TEFRA system. For each cost reporting period, a hospital-specific 
ceiling on payments was determined by multiplying the hospital's 
updated target amount by the number of total current year Medicare 
discharges. (Generally, in this document when we refer to discharges, 
the intent is to describe Medicare discharges.) The August 30, 2002 
final rule further details the payment policy under the TEFRA system 
(67 FR 55954).
    In the August 30, 2002 final rule, we also presented an in-depth 
discussion of the LTCH PPS, including the patient classification 
system, relative weights, payment rates, additional payments, and the 
BN requirements mandated by section 123 of the BBRA. The same final 
rule that established regulations for the LTCH PPS under 42 CFR part 
412, subpart O, also contained LTCH provisions related to covered 
inpatient services, limitation on charges to beneficiaries, medical 
review requirements, furnishing of inpatient hospital services directly 
or under arrangement, and reporting and recordkeeping requirements. We 
refer readers to the August 30, 2002 final rule for a comprehensive 
discussion of the research and data that supported the establishment of 
the LTCH PPS (67 FR 55954).
    In the June 6, 2003 Federal Register, we published a final rule 
that set forth the FY 2004 annual update of the payment rates for the 
Medicare PPS for inpatient hospital services furnished by LTCHs (68 FR 
34122). It also changed the annual period for which the payment rates 
are effective. The annual updated rates are now effective from July 1 
through June 30 instead of from October 1 through September 30. We 
refer to the July through June time period as a ``long-term care 
hospital rate year'' (LTCH PPS rate year). In addition, we changed the 
publication schedule for the annual update to allow for an effective 
date of July 1. The payment amounts and factors used to determine the 
annual update of the LTCH PPS Federal rate are based on a LTCH PPS rate 
year. While the LTCH payment rate update is effective July 1, the 
annual update of the DRG classifications and relative weights for LTCHs 
are linked to the annual adjustments of the acute care hospital 
inpatient DRGs and are effective each October 1.
    In the Prospective Payment System for Long-Term Care Hospitals RY 
2007: Annual Payment Rate Updates, Policy Changes, and Clarifications 
final rule (71 FR 27798) (hereinafter referred to as the RY 2007 LTCH 
PPS final rule), we set forth the 2007 LTCH PPS rate year annual update 
of the payment rates for the Medicare PPS for inpatient hospital 
services provided by LTCHs. We also adopted the ``Rehabilitation, 
Psychiatric, Long-Term Care (RPL)'' market basket under the LTCH PPS in 
place of the excluded hospital with capital market basket. In addition, 
we implemented a zero percent update to the LTCH PPS Federal rate for 
RY 2007. We also revised the existing payment adjustment for short stay 
outlier (SSO) cases by reducing part of the existing payment formula 
and adding a fourth component to that payment formula. We also 
sunsetted the surgical DRG exception to the payment policy established 
under the 3-day or less interruption of stay policy. Finally, we 
clarified the policy at Sec.  412.534(c) for adjusting the LTCH PPS 
payment so that the LTCH PPS payment is equivalent to what would 
otherwise be payable under Sec.  412.1(a).
    The Medicare, Medicaid and SCHIP Extension Act of 2007 (MMSEA) 
(Pub.L. 110-173) was enacted on December 29, 2007 and has various 
effects on the LTCH PPS. The new law's provisions also have varying 
time frames of applicability. First, we note that certain provisions of 
the MMSEA provided that Secretary shall not apply, for cost reporting 
periods beginning on or after the date of the enactment of the Act 
(December 29, 2007) for a 3-year period: the extension of payment 
adjustments at Sec.  412.534 to ``grandfathered LTCHs'' (a long term 
care hospital identified by the amendment made by section 4417(a) of 
Pub. L. 105-33); and the payment adjustment at Sec.  412.536 to 
``freestanding'' LTCHs. In addition, the new law provides that the 
Secretary shall not apply, for the 3-year period beginning on the date 
of enactment of the Act the revision to the SSO policy at Sec.  
412.529(c)(3)(i) that was finalized in 72 FR 26904 and 26992 and the 
one-time adjustment to the payment rates provided for in Sec.  
412.523(d)(3). The statute also provides that the base rate for RY 2008 
be the same as the base rate for RY 2007 (the revised base rate, 
however, does not apply to discharges occurring on or after July 1, 
2007 and before April 1, 2008); for a 3-year moratorium (with specified 
exceptions) on the establishment of new LTCHs, LTCH satellites, and on 
the increase in the number of LTCH beds. The new law also revises in 
the threshold percentages for certain co-located LTCHs and LTCH 
satellites governed under Sec.  412.534. Finally, the Act provides for 
an expanded review of medical necessity for admission and continued 
stay at LTCHs. In this proposed rule we are proposing to establish the 
applicable Federal rates for RY 2009 consistent with section 1886(m)(2) 
of the Act as amended by MMSEA. We are also proposing to amend our 
regulations at Sec.  412.523(d)(3) to change the methodology for the 
one-time budget neutrality adjustment and to comply with section 
114(c)(4) of Pub. L. 110-173. We intend to address all other policy 
revisions necessitated by the statutory changes of the new law in the 
future.

B. Criteria for Classification as a LTCH

1. Classification as a LTCH
    Under the existing regulations at Sec.  412.23(e)(1) and (e)(2)(i), 
which implement section 1886(d)(1)(B)(iv)(I) of the Act, to qualify to 
be paid under the

[[Page 5345]]

LTCH PPS, a hospital must have a provider agreement with Medicare and 
must have an average Medicare inpatient LOS of greater than 25 days. 
Alternatively, Sec.  412.23(e)(2)(ii) states that for cost reporting 
periods beginning on or after August 5, 1997, a hospital that was first 
excluded from the PPS in 1986 and can demonstrate that at least 80 
percent of its annual Medicare inpatient discharges in the 12-month 
cost reporting period ending in FY 1997 have a principal diagnosis that 
reflects a finding of neoplastic disease must have an average inpatient 
LOS for all patients, including both Medicare and non-Medicare 
inpatients, of greater than 20 days.
    Section 412.23(e)(3) provides that, subject to the provisions of 
paragraphs (e)(3)(ii) through (e)(3)(iv) of this section, the average 
Medicare inpatient LOS, specified under Sec.  412.23(e)(2)(i) is 
calculated by dividing the total number of covered and noncovered days 
of stay for Medicare inpatients (less leave or pass days) by the number 
of total Medicare discharges for the hospital's most recent complete 
cost reporting period. Section 412.23 also provides that subject to the 
provisions of paragraphs (e)(3)(ii) through (e)(3)(iv) of this section, 
the average inpatient LOS specified under Sec.  412.23(e)(2)(ii) is 
calculated by dividing the total number of days for all patients, 
including both Medicare and non-Medicare inpatients (less leave or pass 
days) by the number of total discharges for the hospital's most recent 
complete cost reporting period.
    In the RY 2005 LTCH PPS final rule (69 FR 25674), we specified the 
procedure for calculating a hospital's inpatient average length of stay 
(ALOS) for purposes of classification as a LTCH. That is, if a 
patient's stay includes days of care furnished during two or more 
separate consecutive cost reporting periods, the total days of a 
patient's stay would be reported in the cost reporting period during 
which the patient is discharged (69 FR 25705). Therefore, we revised 
Sec.  412.23(e)(3)(ii) to specify that, effective for cost reporting 
periods beginning on or after July 1, 2004, in calculating a hospital's 
ALOS, if the days of an inpatient stay involve days of care furnished 
during two or more separate consecutive cost reporting periods, the 
total number of days of the stay are considered to have occurred in the 
cost reporting period during which the inpatient was discharged.
    Fiscal intermediaries (FIs) verify that LTCHs meet the ALOS 
requirements. We note that the inpatient days of a patient who is 
admitted to a LTCH without any remaining Medicare days of coverage, 
regardless of the fact that the patient is a Medicare beneficiary, will 
not be included in the above calculation. Because Medicare would not be 
paying for any of the patient's treatment, data on the patient's stay 
would not be included in the Medicare claims processing systems. In 
order for both covered and noncovered days of a LTCH hospitalization to 
be included, a patient admitted to the LTCH must have at least 1 
remaining benefit day (68 FR 34123).
    The FI's determination of whether or not a hospital qualifies as an 
LTCH is based on the hospital's discharge data from the hospital's most 
recent complete cost reporting period as specified in Sec.  
412.23(e)(3) and is effective at the start of the hospital's next cost 
reporting period as specified in Sec.  412.22(d). However, if the 
hospital does not meet the ALOS requirement as specified in Sec.  
412.23(e)(2)(i) or (ii), the hospital may provide the FI with data 
indicating a change in the ALOS by the same method for the period of at 
least 5 months of the immediately preceding 6-month period (69 FR 
25676). Our interpretation of Sec.  412.23(e)(3) was to allow hospitals 
to submit data using a period of at least 5 months of the most recent 
data from the immediately preceding 6-month period.
    As we stated in the FY 2004 Hospital Inpatient Prospective Payment 
System (IPPS) final rule, published in the August 1, 2003 Federal 
Register, prior to the implementation of the LTCH PPS, we did rely on 
data from the most recently submitted cost report for purposes of 
calculating the ALOS (68 FR 45464). The calculation to determine 
whether an acute care hospital qualifies for LTCH status was based on 
total days and discharges for LTCH inpatients. However, with the 
implementation of the LTCH PPS, for the ALOS specified under Sec.  
412.23(e)(2)(i), we revised Sec.  412.23(e)(3)(i) to only count total 
days and discharges for Medicare inpatients (67 FR 55970 through 
55974). In addition, the ALOS specified under Sec.  412.23(e)(2)(ii) is 
calculated by dividing the total number of days for all patients, 
including both Medicare and non-Medicare inpatients (less leave or pass 
days) by the number of total discharges for the hospital's most recent 
complete cost reporting period. As we discussed in the FY 2004 IPPS 
final rule, we are unable to capture the necessary data from our 
existing cost reporting forms (68 FR 45464). Therefore, we notified FIs 
and LTCHs that until the cost reporting forms are revised, for purposes 
of calculating the ALOS, we will be relying upon census data extracted 
from Medicare Provider Analysis and Review (MedPAR) files that reflect 
each LTCH's cost reporting period (68 FR 45464). Requirements for 
hospitals seeking classification as LTCHs that have undergone a change 
in ownership, as described in Sec.  489.18, are set forth in Sec.  
412.23(e)(3)(iv).
2. Hospitals Excluded From the LTCH PPS
    The following hospitals are paid under special payment provisions, 
as described in Sec.  412.22(c), and therefore, are not subject to the 
LTCH PPS rules:
     Veterans Administration hospitals.
     Hospitals that are reimbursed under State cost control 
systems approved under 42 CFR part 403.
     Hospitals that are reimbursed in accordance with 
demonstration projects authorized under section 402(a) of the Social 
Security Amendments of 1967 (Pub. L. 90-248) (42 U.S.C. 1395b-1) or 
section 222(a) of the Social Security Amendments of 1972 (Pub. L. 92-
603) (42 U.S.C. 1395b-1 (note)) (Statewide all-payer systems, subject 
to the rate-of-increase test at section 1814(b) of the Act).
     Nonparticipating hospitals furnishing emergency services 
to Medicare beneficiaries.

C. Transition Period for Implementation of the LTCH PPS

    In the August 30, 2002 final rule (67 FR 55954), we provided for a 
5-year transition period. During this 5-year transition period, a 
LTCH's total payment under the PPS was based on an increasing 
percentage of the Federal rate with a corresponding decrease in the 
percentage of the LTCH PPS payment that is based on reasonable cost 
concepts. However, effective for cost reporting periods beginning on or 
after October 1, 2006, total LTCH PPS payments are based on 100 percent 
of the Federal rate.

D. Limitation on Charges to Beneficiaries

    In the August 30, 2002 final rule, we presented an in-depth 
discussion of beneficiary liability under the LTCH PPS (67 FR 55974 
through 55975). In the RY 2005 LTCH PPS final rule (69 FR 25676), we 
clarified that the discussion of beneficiary liability in the August 
30, 2002 final rule was not meant to establish rates or payments for, 
or define Medicare-eligible expenses. Under Sec.  412.507, if the 
Medicare payment to the LTCH is the full LTC-DRG payment amount, as 
consistent with other established hospital prospective payment systems, 
a LTCH may not bill a Medicare beneficiary for more than the deductible 
and coinsurance amounts as

[[Page 5346]]

specified under Sec.  409.82, Sec.  409.83, and Sec.  409.87 and for 
items and services as specified under Sec.  489.30(a). However, under 
the LTCH PPS, Medicare will only pay for days for which the beneficiary 
has coverage until the SSO threshold is exceeded. Therefore, if the 
Medicare payment was for a SSO case (Sec.  412.529) that was less than 
the full LTC-DRG payment amount because the beneficiary had 
insufficient remaining Medicare days, the LTCH could also charge the 
beneficiary for services delivered on those uncovered days (Sec.  
412.507).

E. Administrative Simplification Compliance Act (ASCA) and Health 
Insurance Portability and Accountability Act (HIPAA) Compliance

    Claims submitted to Medicare must comply with both the 
Administrative Simplification Compliance Act (ASCA) (Pub. L. 107-105), 
and Health Insurance Portability and Accountability Act of 1996 (HIPAA) 
(Pub. L. 104-191). Section 3 of the ASCA requires that the Medicare 
Program deny payment under Part A or Part B for any expenses incurred 
for items or services ``for which a claim is submitted other than in an 
electronic form specified by the Secretary.'' Section 1862(h) of the 
Act (as added by section 3(a) of the ASCA) provides that the Secretary 
shall waive such denial in two specific types of cases and may also 
waive such denial ``in such unusual cases as the Secretary finds 
appropriate'' (68 FR 48805). Section 3 of the ASCA operates in the 
context of the HIPAA regulations, which include, among other 
provisions, the transactions and code sets standards requirements 
codified as 45 CFR parts 160 and 162, subparts A and I through R 
(generally known as the Transactions Rule). The Transactions Rule 
requires covered entities, including covered health care providers, to 
conduct certain electronic healthcare transactions according to the 
applicable transactions and code sets standards.

II. Summary of the Provisions of This Proposed Rule

    In this proposed rule, we propose to revise the LTCH PPS payment 
rate update cycle and make other policy changes and clarifications. The 
following is a summary of the major areas that we are addressing in 
this proposed rule.
    In section III. of this proposed rule, we discuss the LTCH PPS 
patient classification and the relative weights which are linked to the 
annual adjustments of the acute care hospital inpatient DRG system, and 
are based on the annual revisions to the International Classification 
of Diseases, Ninth Revision, Clinical Modification (ICD-9-CM) codes 
effective each October 1. In this section, we also summarize the 
severity adjusted MS-LTC-DRGs and the development of the relative 
weights for FY 2008 as established in the FY 2008 IPPS final rule with 
comment period.
    In section IV.B. of this proposed rule, we are proposing to extend 
the rate year cycle for RY 2009 to a 15-month period, from July 1, 2008 
through September 30, 2009. We would continue to have an update to the 
MS-LTC-DRG classifications and weights effective for October 1, 2008. 
We are proposing to have one consolidated annual update to both the 
rates and the classifications and weights beginning October 1, 2009.
    As discussed in section IV.E.2. of this proposed rule, we are 
proposing a 3.5 percent market basket update to the LTCH PPS Federal 
rate for the 2009 LTCH PPS rate year based on the most recent market 
basket estimate for the proposed 15-month 2009 LTCH PPS rate year. Also 
in section IV. of this proposed rule, we discuss the prospective 
payment rate for RY 2009.
    In section IV. D. of this proposed rule, we discuss the possible 
one-time adjustment to the Federal payment rate under Sec.  
412.523(d)(3). Consistent with section 114(c)(4) of Public Law 110-173, 
we are not proposing any adjustment under Sec.  412.523(d)(3). However, 
at this time, we are proposing to make a change to the methodology and 
changes reflecting the requirements of section 114(c)(4) of Public Law 
110-173 to the regulatory text.
    In section VI. of this proposed rule, we discuss the proposed 
updates to the payment rates, including the proposed revisions to the 
wage index, the labor-related share, the cost-of-living adjustment 
(COLA) factors, and the outlier threshold, for the 2009 LTCH PPS rate 
year.
    In section IX. of this proposed rule, we discuss our on-going 
monitoring protocols under the LTCH PPS.
    In section X. of this proposed rule, we present an update of 
Research Triangle Institute's (RTI) analysis relating to the 
development of LTCH patient- and facility-level criteria.
    In section XII. of this proposed rule, we analyze the impact of the 
proposed changes presented in this proposed rule on Medicare 
expenditures, Medicare-participating LTCHs, and Medicare beneficiaries.

III. Medicare Severity Long-Term Care Diagnosis-Related Group (MS-LTC-
DRG) Classifications and Relative Weights

[If you choose to comment on issues in this section, please include the 
caption ``MS-LTC-DRG CLASSIFICATIONS AND RELATIVE WEIGHTS'' at the 
beginning of your comments.]

A. Background

    Section 123 of the BBRA requires that the Secretary implement a PPS 
for LTCHs (that is, a per discharge system with a DRG-based patient 
classification system reflecting the differences in patient resources 
and costs). Section 307(b)(1) of the BIPA modified the requirements of 
section 123 of the BBRA by requiring that the Secretary examine ``the 
feasibility and the impact of basing payment under such a system (the 
LTCH PPS) on the use of existing (or refined) hospital DRGs that have 
been modified to account for different resource use of LTCH patients, 
as well as the use of the most recently available hospital discharge 
data.''
    When the LTCH PPS was implemented for cost reporting periods 
beginning on or after October 1, 2002, we adopted the same DRG patient 
classification system (that is, the CMS DRGs) that was utilized at that 
time under the hospital inpatient prospective payment system (IPPS). As 
a component of the LTCH PPS, we refer to the patient classification 
system as the ``LTC-DRGs.'' As discussed in greater detail below, 
although the patient classification system used under both the LTCH PPS 
and the IPPS are the same, the relative weights are different. The 
established relative weight methodology and data used under the LTCH 
PPS result in LTC-DRG relative weights that reflect ``the different 
resource use of long-term care hospital patients consistent with the 
statute''.
    As part of our efforts to better recognize severity of illness 
among patients, in the FY 2008 IPPS final rule with comment period (72 
FR 47130), the Medicare Severity diagnosis related groups (MS-DRGs) and 
the Medicare Severity long-term care diagnosis related groups (MS-LTC-
DRGs) were adopted for the IPPS and the LTCH PPS, respectively, 
effective October 1, 2007 (FY 2008). For a full description of the 
development and implementation of the MS-DRGs and MS-LTC-DRGs, see the 
FY 2008 IPPS final rule with comment period (72 FR 47141 through 47175 
and 47277 through 47299). (We note that in that same final rule, we 
revised the regulations at Sec.  412.503 to specify that for LTCH 
discharges occurring on or

[[Page 5347]]

after October 1, 2007, when applying the provisions of this subpart for 
policy descriptions and payment calculations, all references to LTC-
DRGs would be considered a reference to MS-LTC-DRGs. For the remainder 
of this section, we present the discussion in terms of the current MS-
LTC-DRG patient classification unless specifically referring to the 
previous LTC-DRG patient classification system (that was in effect 
before October 1, 2007).) We believe the MS-DRGs (and by extension, the 
MS-LTC-DRGs) represent a substantial improvement over the previous CMS 
DRGs in their ability to differentiate cases based on severity of 
illness and resource consumption.
    The MS-DRGs represent an increase in the number of DRGs by 207 
(that is, from 538 to 745) (72 FR 47171). In addition to improving the 
DRG system's recognition of severity of illness, we believe the MS-DRGs 
are responsive to the public comments that were made on the FY 2007 
IPPS proposed rule with respect to how we should undertake further DRG 
reform. The MS-DRGs use the CMS DRGs as the starting point for revising 
the DRG system to better recognize resource complexity and severity of 
illness. We have generally retained all of the refinements and 
improvements that have been made to the base DRGs over the years that 
recognize the significant advancements in medical technology and 
changes to medical practice.
    In accordance with section 123 of the BBRA as amended by section 
307(b)(1) of the BIPA and Sec.  412.515, we use information derived 
from LTCH PPS patient records to classify LTCH discharges into distinct 
MS-LTC-DRGs based on clinical characteristics and estimated resource 
needs. As stated above, the MS-LTC-DRGs used as the patient 
classification component of the LTCH PPS correspond to the hospital 
inpatient MS-DRGs in the IPPS. We assign an appropriate weight to the 
MS-LTC-DRGs to account for the difference in resource use by patients 
exhibiting the case complexity and multiple medical problems 
characteristic of LTCHs.
    In a departure from the IPPS, we use low volume MS-LTC-DRGs (less 
than 25 LTCH cases) in determining the MS-LTC-DRG relative weights, 
since LTCHs do not typically treat the full range of diagnoses as do 
acute care hospitals. To manage the large number of low volume MS-LTC-
DRGs (all MS-LTC-DRGs with fewer than 25 LTCH cases), for purposes of 
determining the relative weights, we group low volume MS-LTC-DRGs into 
5 quintiles based on average charge per discharge. (A detailed 
discussion of the application of the Lewin Group ``quintile'' model 
that was used to develop the LTC-DRGs appears in the August 30, 2002 
LTCH PPS final rule (67 FR 55978).) We also account for adjustments to 
payments for short-stay outlier (SSO) cases (that is, cases where the 
covered length of stay (LOS) at the LTCH is less than or equal to five-
sixths of the geometric ALOS for the MS-LTC-DRG), and we make 
adjustments to account for nonmonotonicity, when necessary (as 
described below in this section).

B. Patient Classifications Into MS-LTC-DRGs

    Generally, under the LTCH PPS, a Medicare payment is made at a 
predetermined specific rate for each discharge; that payment varies by 
the MS-LTC-DRG to which a beneficiary's stay is assigned. Cases are 
classified into MS-LTC-DRGs for payment based on the following six data 
elements:
     Principal diagnosis.
     Up to eight additional diagnoses.
     Up to six procedures performed.
     Age.
     Sex.
     Discharge status of the patient.
    Upon the discharge of the patient from a LTCH, the LTCH must assign 
appropriate diagnosis and procedure codes from the most current version 
of the International Classification of Diseases, Ninth Revision, 
Clinical Modification (ICD-9-CM). HIPAA Transactions and Code Sets 
Standards regulations at 45 CFR parts 160 and 162 require that no later 
than October 16, 2003, all covered entities must comply with the 
applicable requirements of subparts A and I through R of part 162. 
Among other requirements, those provisions direct covered entities to 
use the ASC X12N 837 Health Care Claim: Institutional, Volumes 1 and 2, 
version 4010, and the applicable standard medical data code sets for 
the institutional health care claim or equivalent encounter information 
transaction (see 45 CFR 162.1002 and 45 CFR 162.1102). For additional 
information on the ICD-9-CM Coding System, refer to the FY 2008 IPPS 
final rule with comment period (72 FR 47241 through 47243 and 47277 
through 47281). We also refer readers to the detailed discussion on 
correct coding practices in the August 30, 2002 LTCH PPS final rule (67 
FR 55981 through 55983). Additional coding instructions and examples 
are published in the Coding Clinic for ICD-9-CM.
    Medicare contractors (that is, fiscal intermediaries (FIs), now 
called Medicare Administrative Contractors (MACs)) enter the clinical 
and demographic information into their claims processing systems and 
subject this information to a series of automated screening processes 
called the Medicare Code Editor (MCE). These screens are designed to 
identify cases that require further review before assignment into a MS-
LTC-DRG can be made. During this process, the following types of cases 
are selected for further development:
     Cases that are improperly coded. (For example, diagnoses 
are shown that are inappropriate, given the sex of the patient. Code 
68.69, Other and unspecified radical abdominal hysterectomy, would be 
an inappropriate code for a male.)
     Cases including surgical procedures not covered under 
Medicare. (For example, organ transplant in a non-approved transplant 
center.)
     Cases requiring more information. (For example, ICD-9-CM 
codes are required to be entered at their highest level of specificity. 
There are valid 3-digit, 4-digit, and 5-digit codes. That is, code 262, 
Other severe protein-calorie malnutrition, contains all appropriate 
digits, but if it is reported with either fewer or more than 3 digits, 
the claim will be rejected by the MCE as invalid.)
    After screening through the MCE, each claim is classified into the 
appropriate MS-LTC-DRG by the Medicare LTCH GROUPER software. The 
Medicare GROUPER software, which is used under the LTCH PPS, is 
specialized computer software, and is the same GROUPER software program 
used under the IPPS. The GROUPER software was developed as a means of 
classifying each case into a MS-LTC-DRG on the basis of diagnosis and 
procedure codes and other demographic information (age, sex, and 
discharge status). Following the MS-LTC-DRG assignment, the Medicare 
contractor (FI or MAC) determines the prospective payment amount by 
using the Medicare PRICER program, which accounts for hospital-specific 
adjustments. Under the LTCH PPS, we provide an opportunity for the LTCH 
to review the MS-LTC-DRG assignments made by the Medicare contractor 
and to submit additional information within a specified timeframe as 
specified in Sec.  412.513(c).
    The GROUPER software is used both to classify past cases to measure 
relative hospital resource consumption to establish the DRG weights and 
to classify current cases for purposes of determining payment. The 
records for all Medicare hospital inpatient discharges are maintained 
in the MedPAR file. The data in this file are used to evaluate possible 
MS-DRG classification changes and to recalibrate the MS-DRG and MS-LTC-
DRG relative

[[Page 5348]]

weights during CMS' annual update under both the IPPS (Sec.  412.60(e)) 
and the LTCH PPS (Sec.  412.517), respectively. As discussed in greater 
detail in section III.D. of this preamble, with the implementation of 
section 503(a) of the Medicare Prescription Drug, Improvement, and 
Modernization Act of 2003 (MMA) (Pub. L. 108-173), there is the 
possibility that one feature of the GROUPER software program may be 
updated twice during a Federal FY (FFY) (October 1 and April 1) as 
required by the statute for the IPPS (69 FR 48954 through 48957). 
Specifically, as we discussed in the FY 2008 IPPS final rule with 
comment period (72 FR 47227 through 47278), diagnosis and procedure 
codes for new medical technology have the potential to be created and 
added to existing MS-DRGs (and MS-LTC-DRGs) in the middle of the FFY on 
April 1. New codes would be added to their predecessor MS-DRGs and MS-
LTC-DRGs; no new MS-DRGs would be created. Additionally, this policy 
change will have no effect on the MS-LTC-DRG relative weights (during 
the FY), which will continue to be updated only once a year (October 
1), nor will there be any impact on Medicare payments under the LTCH 
PPS during the FY as result of this policy. The use of the ICD-9-CM 
code set is also compliant with the current requirements of the 
Transactions and Code Sets Standards regulations at 45 CFR parts 160 
and 162, published in accordance with HIPAA.

C. Organization of the MS-LTC-DRGs

    The MS-DRGs (used under the IPPS) and the MS-LTC-DRGs (used under 
the LTCH PPS) are based on the CMS DRG structure. As noted above in 
this section, we refer to the DRGs under the LTCH PPS as MS-LTC-DRGs 
although they are structurally identical to the DRGs used under the 
IPPS. The MS-DRGs are organized into 25 major diagnostic categories 
(MDCs), most of which are based on a particular organ system of the 
body; the remainder involve multiple organ systems (such as MDC 22, 
Burns). Within most MDCs, cases are then divided into surgical DRGs and 
medical DRGs. Surgical DRGs are assigned based on a surgical hierarchy 
that orders operating room (O.R.) procedures or groups of O.R. 
procedures by resource intensity. The GROUPER software program does not 
recognize all ICD-9-CM procedure codes as procedures affecting DRG 
assignment, that is, procedures which are not surgical (for example, 
EKG), or minor surgical procedures (for example, 86.11, Biopsy of skin 
and subcutaneous tissue).
    In developing Version 25.0 of the GROUPER program (the FY 2008 MS-
DRGs), the diagnoses comprising the CC list were completely redefined. 
The revised CC list is primarily comprised of significant acute 
disease, acute exacerbations of significant chronic diseases, advanced 
or end stage chronic diseases, and chronic diseases associated with 
extensive debility. In general, most chronic diseases were not included 
on the revised CC list. For a patient with a chronic disease, a 
significant acute manifestation of the chronic disease was required to 
be present and coded for the patient to be assigned a CC.
    In addition to the revision of the CC list, each CC was also 
categorized as a major CC (MCC) or a CC based on relative resource use. 
Approximately 12 percent of all diagnoses codes were classified as a 
major CC (MCC), 24 percent as a CC, and 64 percent as a non CC. 
Diagnoses closely associated with mortality (ventricular fibrillation, 
cardiac arrest, shock, and respiratory arrest) were assigned as an MCC 
if the patient lived but as a non CC if the patient died.
    The MCC, CC, and non CC categorization was used to subdivide the 
surgical and medical DRGs into up to three levels, with a case being 
assigned to the most resource intensive level (for example, a case with 
two secondary diagnoses that are categorized as an MCC and a CC is 
assigned to the MCC level). To create the MS-DRGs (and by extension, 
the MS-LTC-DRGs) individual DRGs were subdivided into three, two, or 
one level, depending on the CC impact on resources used for those 
cases.
    As noted above in this section, further information on the 
development and implementation of the MS-DRGs and MS-LTC-DRGs can be 
found in the FY 2008 IPPS final rule with comment period (72 FR 47138 
through 47175 and 47277 through 47299).

D. Method for Updating the MS-LTC-DRG Classifications and Relative 
Weights

1. Background
    Under the LTCH PPS, relative weights for each MS-LTC-DRG are a 
primary element used to account for the variations in cost per 
discharge and resource utilization among the payment groups (that is, 
the MS-LTC-DRGs). To ensure that Medicare patients classified to each 
MS-LTC-DRG have access to an appropriate level of services and to 
encourage efficiency, each year based on the best available data, we 
calculate a relative weight for each MS-LTC-DRG that represents the 
resources needed by an average inpatient LTCH case in that MS-LTC-DRG. 
For example, cases in a MS-LTC-DRG with a relative weight of 2 will, on 
average, cost twice as much as cases in a MS-LTC-DRG with a relative 
weight of 1. Under Sec.  412.517, the MS-LTC-DRG classifications and 
weighting factors (that is, relative weights) are adjusted annually to 
reflect changes in factors affecting the relative use of LTCH 
resources, including treatment patterns, technology and number of 
discharges.
    In the June 6, 2003 LTCH PPS final rule (68 FR 34122 through 
34125), we changed the LTCH PPS annual payment rate update cycle to be 
effective July 1 through June 30 instead of October 1 through September 
30. In addition, because the patient classification system utilized 
under the LTCH PPS is the same DRG system that is used under the IPPS, 
in that same final rule, we explained that the annual update of the 
LTC-DRG classifications and relative weights will continue to remain 
linked to the annual reclassification and recalibration of the CMS DRGs 
used under the IPPS (as is the case with the MS-DRGs effective for 
discharges occurring on or after October 1, 2007 (see Sec.  412.503)). 
Therefore, we specified that we will continue to update the LTC-DRG 
classifications and relative weights to be effective for discharges 
occurring on or after October 1 through September 30 each year. We 
further stated at that time that we will publish the annual proposed 
and final update of the LTC-DRGs in same notice as the proposed and 
final update for the IPPS (69 FR 34125). (We note that in section IV.B. 
of this preamble, we are proposing to revise Sec.  412.535 in order to 
consolidate the annual July 1 and October 1 LTCH PPS update cycles, so 
that beginning with FY 2010, both the annual update to the standard 
Federal rate (and other rate and policy changes) and the annual update 
to the MS-LTC-DRGs would be presented in a single Federal Register 
publication to be effective on October 1 each year.) Under existing 
Sec.  412.535(b), the FY 2008 update of the LTCH PPS patient 
classification system and relative weights was presented in the FY 2008 
IPPS final rule with comment (72 FR 47277 through 47299). For the 
reader's benefit, we are providing a summary of the discussion 
presented in that final rule with comment in section III.D.2. of this 
preamble.
    For FY 2008, the MS-LTC-DRG classifications and relative weights 
were updated based on LTCH data from the FY 2006 MedPAR file, which 
contained hospital bills data from the March 2007

[[Page 5349]]

update. The MS-LTC-DRG patient classification system for FY 2008 
consists of 745 DRGs that formed the basis of the Version 25.0 GROUPER 
program utilized under the LTCH PPS. The 745 MS-LTC-DRGs included two 
``error DRGs.'' As in the IPPS, we included two error DRGs in which 
cases that cannot be assigned to valid DRGs will be grouped. These two 
error DRGs are MS-LTC-DRG 998 (Principal Diagnosis Invalid as a 
Discharge Diagnosis) and MS-LTC-DRG 999 (Ungroupable). The other 743 
MS-LTC-DRGs are the same DRGs used in the IPPS GROUPER program for FY 
2008 (Version 25.0).
    In the past, the annual update to the CMS DRGs was based on the 
annual revisions to the ICD-9-CM codes and was effective each October 
1. The ICD-9-CM coding update process was revised as discussed in 
greater detail in the FY 2005 IPPS final rule (69 FR 48953 through 
48957). Specifically, section 503(a) of the MMA includes a requirement 
for updating diagnosis and procedure codes twice a year instead of the 
former process of annual updates on October 1 of each year. This 
requirement is included as part of the amendments to the Act relating 
to recognition of new medical technology under the IPPS. (For 
additional information on this provision, including its implementation 
and its impact on the LTCH PPS, refer to the FY 2005 IPPS final rule 
(69 FR 48953 through 48957) and the RY 2006 LTCH PPS final rule (70 FR 
24172 through 24177).) As noted above in this section, with the 
implementation of section 503(a) of the MMA, there is the possibility 
that one feature of the GROUPER software program may be updated twice 
during a FFY (October 1 and April 1) as required by the statute for the 
IPPS. Specifically, diagnosis and procedure codes for new medical 
technology may be created and added to existing DRGs in the middle of 
the FFY on April 1. No new MS-LTC-DRGs will be created or deleted. 
Consistent with our current practice, any changes to the MS-DRGs or 
relative weights will be made at the beginning of the next FFY (October 
1). Therefore, there will not be any impact on MS-LTC-DRG payments 
under the LTCH PPS until the following October 1 (although the new ICD-
9-CM diagnosis and procedure codes would be recognized April 1).
    As we explained in the FY 2008 IPPS final rule with comment period 
(72 FR 47277), annual changes to the ICD-9-CM codes historically were 
effective for discharges occurring on or after October 1 each year. 
Thus, the manual and electronic versions of the GROUPER software, which 
are based on the ICD-9-CM codes, were also revised annually and 
effective for discharges occurring on or after October 1 each year. The 
patient classification system used under the LTCH PPS (MS-LTC-DRGs) is 
the same DRG patient classification system used under the IPPS, which 
historically had been updated annually and was effective for discharges 
occurring on or after October 1 through September 30 each year. We have 
also explained that since we do not publish a mid-year IPPS rule, we 
will assign any new diagnosis or procedure codes implemented on April 1 
to the same DRG in which its predecessor code was assigned, so that 
there will be no impact on the DRG assignments until the following 
October 1. Any coding updates will be available through the Web sites 
provided in section II.G.10. of the preamble of the FY 2008 IPPS final 
rule with comment period (72 FR 47241 through 47243) and through the 
Coding Clinic for ICD-9-CM. Publishers and software vendors currently 
obtain code changes through these sources to update their code books 
and software system. If new codes are implemented on April 1, revised 
code books and software systems, including the GROUPER software 
program, will be necessary because we must use current ICD-9-CM codes. 
Therefore, for purposes of the LTCH PPS, because each ICD-9-CM code 
must be included in the GROUPER algorithm to classify each case into a 
MS-LTC-DRG, the GROUPER software program used under the LTCH PPS would 
need to be revised to accommodate any new codes.
    At the September 2007 ICD-9-CM C&M Committee meeting, there were no 
compelling requests for an April 1, 2008 implementation of new ICD-9-CM 
codes, and therefore, we expect that the next update to the ICD-9-CM 
coding system will not occur until October 1, 2008 (FY 2009). 
Therefore, we expect that the ICD-9-CM coding set implemented on 
October 1, 2007, will continue through September 30, 2008 (FY 2008). 
The next update to the MS-LTC-DRGs and relative weights for FY 2009 
will be presented in the FY 2009 IPPS proposed and final rules.
2. FY 2008 MS-LTC-DRG Relative Weights
    In accordance with Sec.  412.523(c), we adjust the LTCH PPS 
standard Federal rate by the MS-LTC-DRG relative weights in determining 
payment to LTCHs for each case. Relative weights for each MS-LTC-DRG 
are a primary element used to account for the variations in cost per 
discharge and resource utilization among the payment groups as 
described in Sec.  412.515. To ensure that Medicare patients who are 
classified to each MS-LTC-DRG have access to services and to encourage 
efficiency, we calculate a relative weight for each MS-LTC-DRG that 
represents the resources needed by an average inpatient LTCH case in 
that MS-LTC-DRG. For example, cases in a MS-LTC-DRG with a relative 
weight of 2 will, on average, cost twice as much as cases in a MS-LTC-
DRG with a weight of 1.
    As we discussed in the FY 2008 IPPS final rule with comment period 
(72 FR 47282), the MS-LTC-DRG relative weights effective under the LTCH 
PPS for Federal FY 2008 were calculated using the March 2007 update of 
FY 2006 MedPAR data and Version 25.0 of the GROUPER software.
    LTCHs often specialize in certain areas, such as ventilator-
dependent patients and rehabilitation or wound care. Some case types 
(DRGs) may be treated, to a large extent, in hospitals that have (from 
a perspective of charges) relatively high (or low) charges. 
Distribution of cases with relatively high (or low) charges in specific 
MS-LTC-DRGs has the potential to inappropriately distort the measure of 
average charges. To account for the fact that cases may not be randomly 
distributed across LTCHs, we use a hospital-specific relative value 
(HSRV) method to calculate relative weights. We believe this method 
removes this hospital-specific source of bias in measuring average 
charges. Specifically, we reduce the impact of the variation in charges 
across providers on any particular MS-LTC-DRG relative weight by 
converting each LTCH's charge for a case to a relative value based on 
that LTCH's average charge. (See the FY 2008 IPPS final rule with 
comment period for further information on the application of the HSRV 
methodology under the LTCH PPS (72 FR 47282).)
    To account for MS-LTC-DRGs with low volume (that is, with fewer 
than 25 LTCH cases), we grouped those ``low volume'' MS-LTC-DRGs into 1 
of 5 categories (quintiles) based on average charges for the purposes 
of determining relative weights. Each of the low volume MS-LTC-DRGs 
grouped to a specific quintile received the same relative weight and 
ALOS using the formula applied to the regular MS-LTC-DRGs (25 or more 
cases). (See the FY 2008 IPPS final rule with comment period for 
further explanation of the development and composition of each of the 5 
low volume quintiles for FY 2008 (72 FR 47283 through 47288).)
    After grouping the cases in the appropriate MS-LTC-DRG, generally, 
we calculated the relative weights by

[[Page 5350]]

first removing statistical outliers and cases with a LOS of 7 days or 
less. Next, we adjusted the number of cases remaining in each MS-LTC-
DRG for the effect of SSO cases under Sec.  412.529. The short-stay 
adjusted discharges and corresponding charges were used to calculate 
``relative adjusted weights'' in each MS-LTC-DRG using the HSRV method. 
In determining the FY 2008 MS-LTC-DRG relative weights, we also made 
adjustments, as necessary, to adjust for nonmonotonicity for the 
severity levels within a specific base MS-LTC-DRG. (Refer to the FY 
2008 IPPS final rule with comment period for further information on the 
treatment of severity levels and adjustments for nonmonotically 
increasing relative weights for FY 2008 (72 FR 47282 through 47283 and 
47293 through 47295).) Furthermore, we determined FY 2008 MS-LTC-DRG 
relative weights for the 185 MS-LTC-DRGs for which there were no LTCH 
cases in the database (that is, LTCH claims from the FY 2006 LTCH 
MedPAR files). (A list of the FY 2008 ``no-volume'' MS-LTC-DRGs and 
further explanation of their FY 2008 relative weight assignment can be 
found in the FY 2008 IPPS final rule with comment period (72 FR 47289 
through 47293).)
    In adopting the MS-LTC-DRGs beginning in FY 2008, we established a 
2-year transition. Specifically, for FY 2008, the first year of the 
transition, 50 percent of the relative weight for a MS-LTC-DRG is based 
on the average LTC-DRG relative weight under Version 24.0 of the LTC-
DRG GROUPER. The remaining 50 percent of the relative weight is based 
on the MS-LTC-DRG relative weight under Version 25.0 of the MS-LTC-DRG 
GROUPER. (See the FY 2008 IPPS final rule with comment period (72 FR 
47295) for additional details on the methodology used to determine the 
transition blended MS-LTC-DRG relative weights for FY 2008.)
    In the RY 2008 LTCH PPS final rule (72 FR 26882), under the broad 
authority conferred upon the Secretary under section 123 of Public Law 
106-113 as amended by section 307(b) of Public Law 106-554 to develop 
the LTCH PPS, we established that beginning with the update for FY 
2008, the annual update to the MS-LTC-DRG classifications and relative 
weights will be done in a budget neutral manner such that estimated 
aggregate LTCH PPS payments would be unaffected, that is, would be 
neither greater than nor less than the estimated aggregate LTCH PPS 
payments that would have been made without the MS-LTC-DRG 
classification and relative weight changes. Historically, we had not 
updated the LTC-DRGs in a budget neutral manner because we believed 
that past fluctuations in the relative weights were primarily due to 
changes in LTCH coding practices rather than changes in patient 
severity. In light of the most recently available LTCH claims data at 
that time, which indicated that LTCH claims data no longer appeared to 
significantly reflect changes in LTCH coding practices in response to 
the implementation of the LTCH PPS, we believed that, beginning with FY 
2008, it is appropriate to update the MS-LTC-DRGs in a budget neutral 
manner (that is, so that estimated aggregate LTCH PPS payments will 
neither increase nor decrease). Accordingly, in that same final rule 
with comment period, we established under Sec.  412.517(b) that the 
annual update to the MS-LTC-DRG classifications and relative weights be 
done in a budget neutral manner. (As noted above in section III.A. of 
this preamble, we revised the regulations at Sec.  412.503 to specify 
that ``MS-LTC-DRG'' is used in place of ``LTC-DRG'' for discharges 
occurring on or after October 1, 2007.) Consistent with that provision, 
we updated the MS-LTC-DRG classifications and relative weights for FY 
2008 based on the most recent available data and included a budget 
neutrality adjustment. For further details on the methodology and 
calculation of the FY 2008 MS-LTC-DRG budget neutrality factor, refer 
to the FY 2008 IPPS final rule with comment period (72 FR 47295 through 
47296).
    Table 11 of the Addendum to the FY 2008 IPPS final rule with 
comment period lists the MS-LTC-DRGs and their respective transition 
blended budget neutral relative weights, geometric mean LOS, ``short-
stay outlier threshold'' (that is, five-sixths of the geometric mean 
LOS), and the ``IPPS Comparable Threshold'' (that is, the IPPS 
geometric average length of stay plus one standard deviation) for each 
MS-LTC-DRG for FY 2008 (see (72 FR 48143 through 48157), and the 
technical correction made in the October 10, 2007 correction notice (72 
FR 57733), which has been reprinted in Table 3 of the Addendum of this 
proposed rule for convenience).
    As we noted previously in this section, there were no new ICD-9-CM 
code requests for an April 1, 2008 update. Therefore, we expect that 
Version 25.0 of the MS-DRG GROUPER software established in the FY 2008 
IPPS final rule with comment period will continue to be effective until 
October 1, 2008. Moreover, the MS-LTC-DRGs and relative weights for FY 
2008 established in Table 11 of that same IPPS final rule with comment 
period (78 FR 48143 through 48157) will continue to be effective until 
October 1, 2008, (just as they would have been even if there had been 
any new ICD-9-CM code requests for an April 1, 2008 update). We note 
that Table 11 was corrected in the FY 2008 IPPS correction notice that 
appeared in the October 10, 2007 Federal Register (72 FR 57733) and is 
hereinafter referred to as the second FY 2008 IPPS correction notice. 
Accordingly, Table 3 in the Addendum of this proposed rule lists the 
MS-LTC-RGs and their respective relative weights, geometric ALOS, 
``Short-Stay Outlier Threshold'' and ``IPPS Comparable Threshold'' that 
we will continue to use for the period of July 1, 2008 through 
September 30, 2009. (As noted above, this table is the same as Table 11 
of the Addendum to the FY 2008 IPPS final rule with comment period, 
including the technical correction made in the second FY 2008 IPPS 
correction notice (72 FR 57733), which has been reprinted in Table 3 of 
the Addendum of this proposed rule for the reader's convenience.) We 
expect the next update to the ICD-9-CM coding system to be presented in 
the FY 2009 IPPS proposed rule (since we expect that there will be no 
April 1, 2008 updates to the ICD-9-CM coding system). In addition, the 
proposed MS-DRGs and GROUPER for FY 2009 that would be used for the 
IPPS and the LTCH PPS, effective October 1, 2008, and the proposed 
update to the MS-LTC-DRG relative weights for FY 2009 will be presented 
in the IPPS FY 2009 proposed rule that will be published in the Federal 
Register.

IV. Proposed Changes to the LTCH PPS Payment Rates and Other Proposed 
Changes for the 2009 LTCH PPS Rate Year

    [If you choose to comment on issues in this section, please include 
the caption ``PROPOSED CHANGES TO LTCH PPS PAYMENT RATES FOR THE 2009 
LTCH PPS RATE YEAR'' at the beginning of your comments.]

A. Overview of the Development of the Payment Rates

    The LTCH PPS was effective beginning with a LTCH's first cost 
reporting period beginning on or after October 1, 2002. Effective with 
that cost reporting period, LTCHs are paid, during a 5-year transition 
period, a total LTCH prospective payment that is comprised of an 
increasing proportion of the LTCH PPS Federal rate and a decreasing 
proportion based on reasonable cost-based principles, unless

[[Page 5351]]

the hospital makes a one-time election to receive payment based on 100 
percent of the Federal rate, as specified in Sec.  412.533. New LTCHs 
(as defined at Sec.  412.23(e)(4)) are paid based on 100 percent of the 
Federal rate, with no phase-in transition payments.
    The basic methodology for determining LTCH PPS Federal prospective 
payment rates is set forth at Sec.  412.515 through Sec.  412.536. In 
this section, we discuss the proposed factors that would be used to 
update the LTCH PPS standard Federal rate for the 2009 LTCH PPS rate 
year that would be effective for LTCH discharges occurring on or after 
July 1, 2008 through September 30, 2009. When we implemented the LTCH 
PPS in the August 30, 2002 LTCH PPS final rule (67 FR 56029 through 
56031), we computed the LTCH PPS standard Federal payment rate for FY 
2003 by updating the best latest available (FY 1998 or FY 1999) 
Medicare inpatient operating and capital cost data, using the excluded 
hospital market basket.
    Section 123(a)(1) of the BBRA requires that the PPS developed for 
LTCHs be budget neutral for the initial year of implementation. 
Therefore, in calculating the standard Federal rate under Sec.  
412.523(d)(2), we set total estimated LTCH PPS payments equal to 
estimated payments that would have been made under the reasonable cost-
based payment methodology had the LTCH PPS not been implemented. 
Section 307(a)(2) of the BIPA specified that the increases to the 
target amounts and the cap on the target amounts for LTCHs for FY 2002 
provided for by section 307(a)(1) of the BIPA shall not be considered 
in the development and implementation of the LTCH PPS. Section 
307(a)(2) of the BIPA also specified that enhanced bonus payments for 
LTCHs provided for by section 122 of Public Law 106-113 were not to be 
taken into account in the development and implementation of the LTCH 
PPS.
    Furthermore, as specified at Sec.  412.523(d)(1), the standard 
Federal rate is reduced by an adjustment factor to account for the 
estimated proportion of outlier payments under the LTCH PPS to total 
estimated LTCH PPS payments (8 percent). For further details on the 
development of the FY 2003 standard Federal rate, see the August 30, 
2002 LTCH PPS final rule (67 FR 56027 through 56037), and for 
subsequent updates to the LTCH PPS Federal rate, refer to the following 
final rules: RY 2004 LTCH PPS final rule (68 FR 34134 through 34140), 
RY 2005 LTCH PPS final rule (69 FR 25682 through 25684), RY 2006 LTCH 
PPS final rule (70 FR 24179 through 24180), RY 2007 LTCH PPS final rule 
(71 FR 27819 through 27827), and RY 2008 LTCH PPS final rule (72 FR 
26870 through 27029).

B. Proposed Consolidation of the Annual Updates for Payment and MS-LTC-
DRG Relative Weights to One Annual Update

    In the August 30, 2002 final rule for the implementation of the 
LTCH PPS, we established a publication schedule at Sec.  412.535 for 
publishing information pertaining to the LTCH PPS. That schedule set a 
publication date of on or before August 1 prior to the beginning of 
each FFY, which coincided with the statutorily mandated publication 
schedule for the IPPS (67 FR 55954). In the June 6, 2003 LTCH PPS final 
rule, we amended Sec.  412.535 to provide that ``(a) Information on the 
unadjusted Federal payment rates and a description of the methodology 
and data used to calculate the payment rates are published on or before 
May 1 prior to the start of each long-term care hospital prospective 
payment system rate year which begins July 1, unless for good cause it 
is published after May 1, but before June 1. (b) Information on the 
LTC-DRG classification and associated weighting factors is published on 
or before August 1 prior to the beginning of each Federal fiscal 
year.'' At the time, we explained that the LTC-DRG patient 
classifications used by the LTCH PPS for FY 2003 are based directly on 
the same version of DRGs used by the IPPS, that is, Grouper 20 (68 FR 
34126). (We note, as discussed above in section III of this proposed 
rule, effective for LTCH PPS discharges occurring on or after October 
1, 2007, all references to LTC-DRGs and DRGs in the existing 
regulations are understood to represent MS-LTC-DRGs. (See Sec.  
412.503.)) Therefore, we did not make any changes to the timing for the 
annual update for LTC-DRG classifications and relative weights. The 
annual update to the DRG classifications and relative weights continues 
to be published on a FFY cycle, as is the update of the acute care 
hospital IPPS DRG system. Our intent in making the change in the 
payment rate update schedule for the LTCH PPS was to avoid concurrent 
publications of the annual updates for these two significant payment 
systems for purposes of administrative feasibility and efficiency. With 
this in mind, we changed the effective date for the annual update of 
the LTCH PPS payment rate from October 1 to July 1 of each year 
beginning with July 1, 2003. We believed this change would help use our 
limited resources effectively and facilitate a timely publication of 
both the IPPS and LTCH PPS proposed and final rules. Thus, currently 
the annual update of the LTCH PPS Federal rates do not coincide with 
the start of the FFY, but rather, are effective prior to the FFY.
    In this proposed rule, we are proposing a change to the current 
schedule for the annual updates of the LTCH PPS Federal payment rates. 
We propose to consolidate the rulemaking cycle for the annual update of 
the LTCH PPS Federal payment rates and description of the methodology 
and data used to calculate these payment rates, with the annual 
updating of the MS-LTC-DRG classifications and associated weighting 
factors for LTCHs so that the updates to the rates and the weights 
would both be effective on October 1 each FFY. Under this proposal, the 
annual updates to the LTCH PPS Federal rates would no longer be 
published with a July 1 effective date.
    In proposing this change to the LTCH PPS rulemaking schedule, we 
took into account comments on prior rules as well as recent input from 
the LTCH industry. After further considering those comments and 
concerns, we agree that having the effective date of the annual update 
of the LTCH PPS Federal payment rates on July 1 of each year while 
retaining the October 1 effective date for updating LTC-DRG 
classifications and weights has proved both burdensome and time-
consuming for all parties involved. Although a consolidated update may 
also be resource intensive, it would eliminate some duplicative 
resource use. For example, some of our resources used for the payment 
simulations that are used to estimate LTCH PPS payments for purposes of 
the respective impact analyses are duplicated for the annual LTCH PPS 
rate update and the annual MS-LTC-DRG update. Moreover, we understand 
the concern that there are increased costs involved in updating the 
billing systems of LTCHs to accommodate two separate updates, one for 
the Federal rate and one for the DRG weights, in the same cost 
reporting period.
    We also considered the possibility that two separate updates could 
increase the potential for calculating payment errors under the LTCH 
PPS.
    In order to revise the payment rate update to an October 1 through 
September 30 period, we propose to first extend the 2009 rate period to 
September 30, 2009 such that RY 2009 would be 15 months. This proposed 
15-month rate period would extend from July 1, 2008 through September 
30, 2009. We believe that the additional 3 months to RY 2009 (July, 
August and

[[Page 5352]]

September), would provide for a smooth transition to a consolidated 
annual update for both the LTCH PPS payment rates and the LTCH PPS MS-
LTC-DRG classifications and weighting factors. (We believe that 
proposing to revise the payment rate update to an October 1 through 
September 30 period by proposing to shorten RY 2009 such that it would 
only be 3 months (that is, July 1, 2008 through September 30, 2008), 
would exacerbate the current burdensome and time-consuming biannual 
update process by resulting in two payment rate changes within a very 
short (3 month) period of time.) Under this proposal, after the 2009 
rate period, the rate period for the LTCH PPS payment rate and other 
policy changes would be October 1 through September 30. (The annual 
update to the MS-LTC-DRG classifications and relative weights would 
continue to be effective on October 1.) The October through September 
rate period would first begin with October 1, 2009. The next update to 
the LTCH PPS Federal rates after RY 2009 would be for RY 2010. (We note 
that if we finalize this proposal to move the annual LTCH PPS rate 
update cycle to October 1 effective October 1, 2009, the LTCH PPS rate 
year would coincide with Federal FY beginning in 2010.) We are 
proposing to make a change to the regulations at Sec.  412.503 to 
redefine the LTCH PPS' rate year to mean October 1 through September 
30. We are also proposing to revise Sec.  412.535 to reflect the 
proposed change to the annual payment rate update cycle described 
above. The discussion of the proposed 15-month market basket update for 
the proposed 2009 rate year can be found below in sections IV.D.2. and 
3. of this proposed rule.

C. LTCH PPS Market Basket

1. Overview of the RPL Market Basket
    Historically, the Medicare program has used a market basket to 
account for price increases in the services furnished by providers. The 
market basket used for the LTCH PPS includes both operating and 
capital-related costs of LTCHs because the LTCH PPS uses a single 
payment rate for both operating and capital-related costs. The 
development of the initial LTCH PPS standard Federal rate for FY 2003, 
using the excluded hospital with capital market basket, is discussed in 
further detail in the August 30, 2002 LTCH PPS final rule (67 FR 56027 
through 56033).
    In the August 30, 2002 final rule (67 FR 56016 through 56017 and 
56030), which implemented the LTCH PPS, we established the use of the 
excluded hospital with capital market basket as the LTCH PPS market 
basket. The excluded hospital with capital market basket was also used 
to update the limits on LTCHs' operating costs for inflation under the 
TEFRA reasonable cost-based payment system. We explained that we 
believe the use of the excluded hospital with capital market basket to 
update LTCHs' costs for inflation was appropriate because the excluded 
hospital market basket (with a capital component) measures price 
increases of the services furnished by excluded hospitals, including 
LTCHs. For further details on the development of the excluded hospital 
with capital market basket, see the RY 2004 LTCH PPS final rule (68 FR 
34134 through 34137).
    In the RY 2007 LTCH PPS final rule (71 FR 27810), we noted that 
based on our research, we did not develop a market basket specific to 
LTCH services. We are still unable to create a separate market basket 
specifically for LTCHs due to the small number of facilities and the 
limited amount of data that is reported (for instance, only 
approximately 15 percent of LTCHs reported contract labor cost data for 
2002). In that same final rule, under the broad authority conferred 
upon the Secretary by section 123 of the BBRA as amended by section 
307(b) of the BIPA, we adopted the ``Rehabilitation, Psychiatric and 
Long-Term Care (RPL) market basket'' as the appropriate market basket 
of goods and services under the LTCH PPS for discharges occurring on or 
after July 1, 2006. Specifically, beginning with the 2007 LTCH PPS rate 
year, for the LTCH PPS, we adopted the use of the RPL market basket 
based on FY 2002 cost report data. We choose to use the FY 2002 
Medicare cost report data because it was the most recent, relatively 
complete cost data for inpatient rehabilitation facilities (IRFs), 
inpatient psychiatric facilities (IPF), and LTCHs available at the time 
of rebasing.
    The RPL market basket is determined based on the operating and 
capital costs of IRFs, IPFs and LTCHs. All IRFs are now paid under the 
IRF PPS Federal payment rate, all LTCHs are now paid 100 percent of the 
Federal rate under the LTCH PPS, and most IPFs are transitioning to 
payment based on 100 percent of the Federal per diem payment amount 
under the IPF PPS (payments to IPFs will be based exclusively on 100 
percent of the Federal rate for cost reporting periods beginning on or 
after January 1, 2008). As we explained in that same final rule, we 
believe a market basket based on the data of IRFs, IPFs and LTCHs is 
appropriate to use under the LTCH PPS since it is the best available 
data that reflects the cost structures of LTCHs.
    For further details on the development of the RPL market basket, 
including the methodology for determining the operating and capital 
portions of the RPL market basket, see the RY 2007 LTCH PPS final rule 
(71 FR 27810 through 27817).
2. Proposed Market Basket Estimate for the 2009 LTCH PPS Rate Year
    As discussed in greater detail above in this section, for the 2009 
LTCH PPS rate year, we are proposing to consolidate the current LTCH 
PPS rate year (payment rates and other policy changes) update and 
fiscal year MS-LTC-DRG update into one annual update cycle. Presently, 
the next payment rate update cycle would be effective July 1, 2008 
through June 30, 2009. In proposing to consolidate the annual payment 
rate and MS-LTC-DRG updates to be effective October 1 each year, we 
would extend the next rate year update by 3 months (through September 
30, 2009), which would make the RY 2009 rate effective for a 15-month 
period. Accordingly, for the proposed 2009 LTCH PPS rate year, we are 
proposing to use a 15-month (that is, July 1, 2008 through September 
30, 2009) estimate of the RPL market basket based on the best available 
data.
    Consistent with our historical practice, we estimate the RPL market 
basket update based on Global Insight, Inc.'s forecast using the most 
recent available data. Global Insight, Inc. is a nationally recognized 
economic and financial forecasting firm that contracts with CMS to 
forecast the components of CMS' market baskets. To determine a 15-month 
market basket update for RY 2009, we calculate the 5-quarter moving 
average index level for July 1, 2008 through September 30, 2009 and the 
4-quarter moving average index level for July 1, 2007 through June 30, 
2008. The percent change in these two values represents the proposed 
15-month market basket update.
    Based on Global Insight's 4th quarter 2007 forecast with history 
through the 3rd quarter of 2007, the projected 15-month market basket 
estimate for the proposed 15-month 2009 LTCH PPS rate year is 3.5 
percent. Therefore, consistent with our historical practice of 
estimating market basket increases based on the best available data, we 
are proposing a market basket update of 3.5 percent for the proposed 
15-month 2009 rate year based on the proposed consolidation of the 
annual updates for payment rates and MS-LTC-DRGs. Furthermore, because 
the proposed RY 2009 update is based on the most recent

[[Page 5353]]

market basket estimate for the 15-month period (currently 3.5 percent), 
we are also proposing that if more recent data are subsequently 
available (for example, a more recent estimate of the market basket), 
we would use such data, if appropriate, to determine the RY 2009 update 
in the final rule. (The proposed update to the standard Federal rate 
for RY 2009 is discussed below in section IV.E. of this preamble.)
    We note that the most recent estimate of the RPL market basket for 
July 1, 2008 through June 30, 2009, based on Global Insight's 4th 
quarter 2007 forecast with history through the 3rd quarter of 2007, is 
3.1 percent. We determine this 12-month market basket update by 
calculating the 4-quarter moving average index level for July 1, 2008 
through June 30, 2009 and the 4-quarter moving average index level for 
July 1, 2007 through June 30, 2008. The percent change in these two 
values represents the proposed 12-month market basket update. 
Consistent with our historical practice of using market basket 
estimates based on the most recent available data, if we were not 
proposing to consolidate the two annual LTCH PPS payment system updates 
by proposing to extend the 2009 LTCH PPS rate year by 3 months, we 
would have proposed a market basket update for a 12 month RY 2009 of 
3.1 percent, based on the most recent estimate of the 12-month RPL 
market basket for July 1, 2008 through June 30, 2009.

D. One-time Prospective Adjustment to the Standard Federal Rate

    As we discussed in the August 30, 2002 LTCH PPS final rule (67 FR 
56027), consistent with the statutory requirement for budget neutrality 
in section 123(a)(1) of the BBRA, we estimated aggregate payments under 
the LTCH PPS for FY 2003 to be equal to the estimated aggregate 
payments that would be made if the LTCH PPS were not implemented. Our 
methodology for estimating payments for purposes of the budget 
neutrality calculations used the best available data at the time and 
necessarily reflected several assumptions (for example, costs, 
inflation factors and intensity of services provided). In conducting 
our budget neutrality calculations, we took into account the statutory 
requirement that certain statutory provisions that affect the level of 
payments to LTCHs in years prior to the implementation of the LTCH PPS 
shall not be taken into account in the development and implementation 
of the LTCH PPS. Specifically, section 307(a)(2) of the BIPA requires 
that the increases to the target amounts and the increases to the cap 
on the target amounts for LTCHs provided for by section 307(a)(1) of 
the BIPA (as set forth in section 1886(b)(3)(J) of the Act) and the 
enhanced bonus payments for LTCHs provided for by section 122 of the 
BBRA (as set forth in section 1886(b)(2)(E) of the Act) are not to be 
taken into account in the development and implementation of the LTCH 
PPS.
    As the LTCH PPS has progressed, we have been monitoring payment 
data in order to evaluate whether there is a significant difference 
between the payments estimated on the basis of the data available at 
the time of the August 30, 2002 LTCH PPS final rule (67 FR 56027 
through 56037) and payment estimates based on more complete data that 
have become available since that time. We indicated from the inception 
of the LTCH PPS that it was possible for the aggregate amount of actual 
payments in FY 2003 to be significantly higher or lower than the 
estimates on which the budget neutrality calculations were based to the 
extent that later, more complete data differ significantly from the 
data that were available at the time of the original calculations.
    Section 123(a)(1) of the BBRA, as amended by section 307(b) of 
BIPA, provides broad authority to the Secretary in developing the LTCH 
PPS, including the authority for establishing appropriate adjustments. 
Under this broad authority to make appropriate adjustments, we provided 
in Sec.  412.523(d)(3) of the regulations, for the possibility of 
making a one-time prospective adjustment to the LTCH PPS rates by July 
1, 2008, so that the effect of any significant difference between 
actual payments and estimated payments for the first year of the LTCH 
PPS would not be perpetuated in the LTCH PPS rates for future years.
    In the RY 2008 LTCH PPS final rule (72 FR 26902), based on the best 
available data at that time, we estimated that total Medicare program 
payments for LTCH services over the next 5 LTCH PPS rate years would be 
$4.65 billion for the 2008 LTCH PPS rate year; $4.85 billion for the 
2009 LTCH PPS rate year; $5.04 billion for the 2010 LTCH PPS rate year; 
$5.25 billion for the 2011 LTCH PPS rate year; and $5.50 billion for 
the 2012 LTCH PPS rate year.
    In this proposed rule, consistent with the methodology established 
in the August 30, 2002 final rule (67 FR 56036), and based on the most 
recent available data, we estimate that total Medicare program payments 
for LTCH services for the next 5 LTCH PPS rate years would be as shown 
in Table 4.

                                 Table 4

                                                             Estimated
                   LTCH PPS rate year                     payments ($ in
                                                             billions)
------------------------------------------------------------------------
2009....................................................            4.67
2010....................................................            4.82
2011....................................................            5.06
2012....................................................            5.36
2013....................................................            5.73
------------------------------------------------------------------------

    In accordance with the methodology established in the August 30, 
2002 LTCH PPS final rule (67 FR 56027 through 56037), these estimates 
are based on the most recent available data. These estimates are also 
based on our estimate of LTCH PPS rate year payments to LTCHs using 
CMS' Office of the Actuary's (OACT) most recent estimate of the RPL 
market basket of 3.1 percent for the 2009 LTCH PPS rate year, 2.8 
percent for the 2010 LTCH PPS rate year, 3.0 percent for the 2011 LTCH 
PPS and 2012 rate years, and 3.1 percent for the 2013 LTCH PPS rate 
year. (We note that OACT develops its spending projections based on 
existing policy. Therefore, changes that have not yet been implemented, 
including those proposed in this proposed rule, and changes as a result 
of the recent Medicare, Medicaid, and SCHIP Extension Act of 2007, are 
not reflected in the spending projections shown in this section.) We 
also considered OACT's most recent projections of changes in Medicare 
beneficiary enrollment that estimate increases in Medicare fee-for-
service beneficiary enrollment of 0.6 percent in the 2009 LTCH PPS rate 
year, 0.7 percent in the 2010 LTCH PPS rate year, 1.2 percent in the 
2011 LTCH PPS rate year, 2.0 percent in the 2012 LTCH PPS rate year, 
and 2.5 percent in the 2013 LTCH PPS rate year. It is important to note 
that, while we provide these estimates of future payments under the 
LTCH PPS in order to provide a projected estimate of payments to LTCHs, 
these estimates will be neither the basis for determining whether the 
one-time budget neutrality adjustment available under Sec.  
412.523(d)(3) should be proposed, nor are these estimates the basis for 
any of the proposed policy changes presented in this proposed rule. It 
is important to note that any proposal regarding the one-time budget 
neutrality adjustment would be based solely on the data related to FY 
2003 that would be available at the time of the proposal, rather than 
on projections of payments under LTCH PPS for future years.
    In the August 30, 2002 LTCH PPS final rule implementing the LTCH 
PPS (67 FR 55954), we set forth the implementing regulations, based 
upon

[[Page 5354]]

the broad authority granted to the Secretary, under section 123 of the 
BBRA (as amended by section 307(b) of the BIPA). Section 123(a)(1) of 
the BBRA required that the system ``maintain budget neutrality.'' The 
statute requires the LTCH PPS to be budget neutral in FY 2003, so that 
estimated aggregate payments under the LTCH PPS for FY 2003 should be 
equal to the estimated aggregate payments that would be made if the 
LTCH PPS were not implemented for FY 2003. The methodology for 
determining the LTCH PPS standard Federal rate for FY 2003 that would 
``maintain budget neutrality'' is described in considerable detail in 
the August 30, 2002 final rule (67 FR 56027 through 56037). As we 
discussed previously in this section, our methodology for estimating 
payments for the purposes of budget neutrality calculations used the 
best available data, and necessarily reflected assumptions in 
estimating aggregate payments that would be made if the LTCH PPS was 
not implemented. In the August 30, 2002 final rule, we also stated our 
intentions to monitor LTCH PPS payment data to evaluate whether later 
data varied significantly from the data available at the time of the 
original budget neutrality calculations (for example, data related to 
inflation factors, intensity of services provided, or behavioral 
response to the implementation of the LTCH PPS). To the extent the 
later data significantly differ from the data employed in the original 
calculations, the aggregate amount of payments during FY 2003 based on 
later data may be higher or lower than the estimates upon which the 
budget neutrality calculations were based. In that same final rule, the 
Secretary exercised his broad authority in establishing the LTCH PPS 
and provided for the possibility of a one-time prospective adjustment 
to the LTCH PPS rates by October 1, 2006, in Sec.  412.523(d)(3). This 
deadline was revised to July 1, 2008, in the RY 2007 LTCH PPS final 
rule. As we discussed in the RY 2007 LTCH PPS final rule (71 FR 27842 
through 27844), because the LTCH PPS was only recently implemented, 
sufficient new data had not yet been generated that would enable us to 
conduct a comprehensive reevaluation of our budget neutrality 
calculations. Therefore, in that same final rule, we did not implement 
the one-time adjustment provided under Sec.  412.523(d)(3) so that the 
effect of any significant difference between actual payments and 
estimated payments for the first year of the LTCH PPS would not be 
perpetuated in the PPS rates for future years. However, we stated that 
we would continue to collect and interpret new data as it became 
available in order to determine whether we should propose such an 
adjustment in the future. Therefore, we revised Sec.  412.523(d)(3) by 
changing the original October 1, 2006 deadline (established in the 
August 30, 2002 final rule that implemented the LTCH PPS) to July 1, 
2008, to postpone the possible one-time adjustment due to the time lag 
in the availability of Medicare data upon which a proposed adjustment 
would be based. We noted that there is a lag time between the 
submission of claims data and cost report data, and the availability of 
that data in the MedPAR files and HCRIS, respectively. As also 
explained in that same final rule, we believed that postponing the 
deadline of the possible one-time prospective adjustment to the LTCH 
PPS rates provided for in Sec.  412.523(d)(3) to July 1, 2008, would 
allow our decisions regarding a possible adjustment to be based on more 
complete and up-to-date data. It should be noted that, in the years 
following the initial implementation of the LTCH PPS, we have already 
adopted some revised policies and adjustments to LTCH PPS payment 
levels. However, none of these revised policies and payment adjustments 
have addressed the intended purpose of the adjustment allowed under 
Sec.  412.523(d)(3) of the regulations, to ensure that any significant 
difference between the original estimates and calculations based on 
more recent data are not perpetuated in the LTCH PPS rates for future 
years. For example, the adjustments that we have made to account for 
coding changes in excess of real severity increases in RY 2007 and RY 
2008 were made to account for changes in coding behavior in the years 
following the implementation of the LTCH PPS, and not to address any 
issue regarding the budget neutrality calculations that were used to 
establish the base rate for the LTCH PPS.
    Section 114(c)(4) of MMSEA provides that the ``Secretary shall not, 
for the 3-year period beginning on the date of the enactment of this 
Act, make the one-time prospective adjustment to long-term care 
hospital prospective payment rates provided for in section 
412.523(d)(3) of title 42, Code of Federal Regulations, or any similar 
provision.'' That provision delays the effective date of any one-time 
budget neutrality adjustment until no earlier than December 29, 2010. 
Therefore, we are proposing to revise Sec.  412.523(d)(3) of the 
regulations to conform with this requirement.
    Prior to the enactment of the Medicare, Medicaid, and SCHIP 
Extension Act of 2007, we had developed a methodology for evaluating 
whether to propose a one-time budget neutrality adjustment under Sec.  
412.523(d)(3) of the regulations. In order to inform the public of our 
thinking, and to stimulate comments for our consideration during the 3-
year delay in implementing any one-time budget neutrality adjustment 
under the law referenced above, we have decided to discuss our analysis 
and its results in this proposed rule. Evaluating the appropriateness 
of the possible one-time prospective adjustment under Sec.  
412.523(d)(3) requires a thorough review of the relevant LTCH data (as 
described below). When we established the FY 2003 standard Federal rate 
in a budget neutral manner, we used the most recent LTCH cost data 
available at that time (that is, FY 1999 data), and trended that data 
forward to estimate what Medicare would have paid to LTCHs in FY 2003 
under the TEFRA payment system if the PPS were not implemented for FY 
2003 (67 FR 56033). We have conducted a thorough review of the relevant 
data. We now have cost data from FY 2002, representing the final year 
LTCHs were paid under the TEFRA payment system. The cost report data 
for FY 2002 is comprised of a high proportion of settled and audited 
cost reports submitted by LTCHs. We also have payment data on the first 
year of the LTCH PPS (that is, FY 2003). On the basis of our review of 
these data sources, we developed a potential methodology for 
determining whether the one-time adjustment available under Sec.  
412.523(d)(3) of the regulations should be proposed. On the basis of 
this methodology, we have also determined a potential method for 
computing an adjustment, if appropriate. Employing that methodology, 
our analysis has indicated that a permanent adjustment factor of 0.9625 
to the LTCH PPS standard Federal rate could be warranted. Consistent 
with the requirements of section 114(c)(4) of the recently enacted 
Medicare, Medicaid, and SCHIP Extension Act of 2007, we are not 
proposing any adjustment for the upcoming rate year. However, we 
welcome public comment on our analysis, which we are presenting in this 
proposed rule. We will consider these comments if and when we decide to 
propose an actual adjustment. We note that in the final rule, we will 
respond to any comments on our proposed changes to Sec.  412.523(d)(3) 
of the regulations that would--(1) specify

[[Page 5355]]

the methodology for the one-time budget neutrality adjustment; and (2) 
implement the requirements of section 114(c)(4) of Public Law 110-173, 
in the final rule.
    In order to determine whether a one-time budget neutrality 
adjustment could be warranted, it is necessary to estimate both 
aggregate payments under the LTCH PPS for FY 2003 and the estimated 
aggregate payments that would have been made under the TEFRA system in 
FY 2003 if the LTCH PPS were not implemented. While we know actual 
TEFRA payments to LTCHs for FY 2002, the last year of payment under 
that methodology, it is necessary to estimate what TEFRA payments would 
have been in FY 2003 if the new LTCH PPS had not been implemented. In 
developing our methodology for evaluating a one-time adjustment, we 
considered whether we should employ actual FY 2003 costs to calculate 
estimated TEFRA payments for FY 2003 or employ costs for FY 2002 
trended forward to FY 2003 as the basis for the calculation. Basing the 
estimate on actual FY 2003 costs would avoid the need to employ any 
factor to update costs from FY 2002 to FY 2003. However, since FY 2003 
was the first year of payment under the LTCH PPS, the cost experience 
of LTCHs in that year would reflect their response to the incentives 
provided by the new payment system, instead of reflecting behavior 
under the reasonable cost payment system. Indeed, implementation of an 
LTCH PPS should directly affect the behavior of LTCHs, and therefore, 
the level of costs in LTCHs. One of the incentives of a PPS is to 
improve efficiency in the delivery of care, which generally results in 
decreased cost per discharge. For this reason, employing FY 2003 costs 
directly could be a poor basis for estimating payments that ``would 
have been made if the LTCH PPS were not implemented.'' On balance, we 
believe that trending forward for 1 year the costs incurred under the 
last year of the TEFRA payment system poses a smaller prospect for 
distortion than using costs incurred during the subsequent year, when 
the incentives faced by LTCHs to reduce costs could have had a 
significant effect. Therefore, we could base our calculation of the 
estimated aggregate payments that would have been made if the LTCH PPS 
were not implemented (that is, estimated FY 2003 TEFRA payments) on FY 
2002 costs, trended forward to FY 2003 using the excluded hospital 
market basket. It may be worth noting in this context that some 
representatives of LTCHs have expressed concern that employing FY 2003 
costs directly would provide a poor basis upon which to estimate 
payments that ``would have been made if the LTCH PPS were not 
implemented'' for precisely the reasons we have just discussed. We 
believe that basing the estimate of FY 2003 TEFRA payments on FY 2002 
costs trended forward should satisfy these concerns.
    In determining whether a one-time budget neutrality adjustment 
could be warranted, the estimate of the payments that would have been 
made in FY 2003 under the TEFRA methodology should be compared to 
estimated payments under the new LTCH PPS in FY 2003. The most direct 
way to determine payments under the new LTCH PPS, of course, is simply 
to aggregate the actual payments calculated under the LTCH PPS 
methodology for the discharges that occurred during the first year of 
the LTCH PPS (FY 2003). However, that approach raises an issue of 
consistency in the use of data. The discharges for which we paid under 
the LTCH PPS during FY 2003 are obviously not the same as the 
discharges for which costs were incurred during the last year of 
payment under the TEFRA methodology, FY 2002. For the reasons we have 
just discussed, we believe that the best way to estimate the TEFRA 
payments that would have been made to LTCHs during FY 2003 is to use 
inflated FY 2002 costs as a proxy for FY 2003 costs. Comparing actual 
FY 2003 LTCH PPS payments to FY 2003 TEFRA payments estimated on the 
basis of FY 2002 discharges would amount to a comparison between 
payments related to two different sets of discharges, potentially 
skewing the results. Therefore consistency suggests that, rather than 
comparing TEFRA payments based on FY 2002 costs updated to FY 2003, to 
aggregate LTCH PPS payments for discharges that actually occurred in FY 
2003, it would be preferable to compare estimated TEFRA payments based 
on updated FY 2002 costs to the estimated payments that would have been 
made under LTCH PPS methodology in FY 2003 for those same FY 2002 
discharges. In other words, we believe that the best approach would be 
to compare--
     Estimated aggregate FY 2003 TEFRA payments calculated on 
the basis of FY 2002 costs updated to FY 2003; to
     Estimated aggregate payments that would have been made in 
FY 2003 under the LTCH PPS methodology, by applying the FY 2003 LTCH 
payment rules to the discharges that occurred in FY 2002.
    In this way, we would ensure that we are comparing the estimated FY 
2003 TEFRA payments, which are based on updated costs incurred for FY 
2002 discharges to the estimated PPS payments that would have been made 
for those same FY 2002 discharges under the new LTCH PPS payment 
methodology.
    Therefore, in the absence of the Medicare, Medicaid, and SCHIP 
Extension Act of 2007, we would have proposed to employ the general 
methodology we have just described to determine: (1) Whether the one-
time adjustment available under Sec.  412.523(d)(3) of the regulations 
should be proposed for RY 2009, and (2) if such adjustment should be 
proposed, the actual proposed adjustment factor. In this proposed rule, 
we would revise the current language of Sec.  412.523(d)(3) of the 
regulations to conform more specifically with this preferred 
methodology. At the time of the final LTCH PPS rule in 2002, we 
described the nature of the one-time adjustment in very general terms. 
Specifically, that section currently provides the following:

    The Secretary reviews payments under this prospective payment 
system and may make a one-time prospective adjustment to the long-
term care hospital prospective payment system rates on or before 
July 1, 2008 so that the effect of any significant difference 
between actual payments and estimated payments for the first year of 
the long term care hospital prospective payment system is not 
perpetuated in the prospective payment rates for future years.

Our policy objective in providing for this one-time budget neutrality 
adjustment has always been to ensure that computations based on the 
earlier, necessarily limited (but at that time best available) data 
available at the inception of the LTCH PPS would not be built 
permanently into the rates if data available at a later date could 
provide more accurate results. Prior to the thorough analysis we 
conducted in preparation for this rate year, we had believed that the 
only appropriate method for meeting this policy objective involved 
employing actual payment data from the first year of payment under the 
LTCH. As we have just discussed, we believe after a thorough evaluation 
of the currently available data in the light of this policy objective, 
that the most appropriate methodology for evaluating an adjustment to 
the original budget neutrality adjustment does not involve comparing 
the payments estimated in the original calculations against the 
``actual payments * * * for the first year,'' strictly speaking. 
Rather, as just

[[Page 5356]]

discussed, considerations of consistency and other factors suggest that 
the most appropriate comparison would employ an estimate of FY 2003 
LTCH PPS payments based on the same set of discharges (from FY 2002) 
which are the basis for the best estimate of what would have been paid 
in FY 2003 under the TEFRA system. As a result of this methodological 
determination, under the broad authority of section 123 of the BBRA, as 
amended by section 307(b) of BIPA, to make appropriate adjustments to 
the LTCH PPS, we are proposing to revise Sec.  412.523(d)(3) to reflect 
the preferred methodology more clearly. As we have discussed 
previously, we are also proposing to revise that section of the 
regulations to correspond with the requirements of section 114(c)(4) of 
the Medicare, Medicaid, and SCHIP Extension Act of 2007. Specifically, 
we are now proposing to revise Sec.  412.523(d)(3) of the regulations 
to read as follows:

    The Secretary reviews payments under this prospective payment 
system and may make a one-time prospective adjustment to the long-
term care hospital prospective payment system rates no earlier than 
December 29, 2010, so that the effect of any significant difference 
between the data used in the original computations and more recent 
data to determine budget neutrality is not perpetuated in the 
prospective payment rates for future years.

Our proposed revision to Sec.  412.523(d)(3) of the regulations would 
continue to provide that the Secretary may make a one-time adjustment 
to the LTCH PPS rates in order to ensure that any ``significant'' 
difference is not perpetuated in the LTCH PPS rates for future years. 
The regulation does not specifically define what constitutes a 
significant difference for this purpose. In the absence of section 
114(c)(4) of the Medicare, Medicaid, and SCHIP Extension Act of 2007, 
we would have proposed to consider as ``significant'' any difference 
greater than or equal to a 0.25 percentage point difference between the 
original budget neutrality calculations and budget neutrality 
calculations based on the more recent data now available. This 
threshold avoids making an adjustment to account for very minor 
deviations between earlier and later estimates of budget neutrality. It 
is also consistent with thresholds that we have employed for similar 
purposes in prospective payment systems. For example, under the capital 
IPPS, we make a forecast error correction in the framework used to 
update the capital Federal rate if a previous forecast of input prices 
varies by at least a 0.25 percentage point from actual input price 
changes (72 FR 47425). We do not believe that we should treat 
differences greater than or equal to 0.25 percent as not 
``significant,'' since the effect of any difference will be magnified 
as the rates are updated each year.
    As discussed previously, absent the requirement of section 
114(c)(4) of the Medicare, Medicaid and SCHIP Extension Act of 2007, we 
would have proposed to use FY 2002 LTCH costs as a basis for estimating 
FY 2003 LTCH TEFRA payments in evaluating whether to propose a one-time 
prospective adjustment under Sec.  412.523(d)(3). We also would have 
proposed to update the FY 2002 costs for inflation to FY 2003 by our 
Office of the Actuary's current estimate of the actual increase in the 
excluded hospital market basket from FY 2002 to FY 2003 of 4.2 percent. 
This updated amount would serve as the proxy for actual FY 2003 TEFRA 
costs in the proposed budget neutrality computation for purposes of 
Sec.  412.523(d)(3). We estimated FY 2003 LTCH TEFRA payments using a 
methodology that is similar in concept to the methodology we used to 
estimate FY 2003 LTCH total payments under the TEFRA system when we 
determined the initial standard Federal rate in the August 30, 2002 
final rule (67 FR 56030 through 56033). We also made modifications to 
the methodology we initially used to estimate FY 2003 LTCH TEFRA 
payments because we are using data from a later period, as discussed in 
greater detail below. In general, we estimated total payments under the 
TEFRA payment system using the following steps:
     Estimate each LTCH's payment per discharge for inpatient 
operating costs under the TEFRA system for FY 2003;
     Estimate each LTCH's payment per discharge for capital-
related costs for FY 2003; and
     Sum each LTCH's estimated operating and capital payment 
per case to determine its estimated total FY 2003 TEFRA payment system 
payment per discharge.

We discuss each of these steps in greater detail below.
    The first step in the process of estimating total FY 2003 payments 
under the TEFRA payment system is to estimate each LTCH's payment per 
discharge for inpatient operating costs under the TEFRA. Until FY 1998, 
the payment methodology for inpatient operating costs under the TEFRA 
payment system was a relatively straightforward process. First, we 
calculated a target amount by dividing the Medicare total inpatient 
operating costs in a base year by the number of Medicare discharges. 
The provider's TEFRA target amount was then updated by a rate-of-
increase percentage (Sec.  413.40(c)(3) of the regulations, as 
established by the Congress, to determine the TEFRA target amount for 
the subsequent cost reporting period (Sec.  413.40(c)(4)(i), (ii)). For 
any particular cost reporting period, the Medicare payment for 
inpatient operating costs would be the lesser of the hospital's 
reasonable costs, or the updated target amount multiplied by the number 
of Medicare discharges during the cost reporting period, that is, the 
TEFRA ceiling (Sec.  413.40(a)(3)).
    The methodology described above, broadly speaking, is the general 
approach that we would use to arrive at an estimate of what Medicare 
payments for hospital inpatient operating costs would have been in FY 
2003 under the TEFRA payment system: each LTCH's FY 2003 target amount 
would be calculated by updating its estimated FY 2002 target amount per 
discharge by the full market basket percentage increase. The sum of all 
LTCH payments for operating costs (TEFRA target amount multiplied by 
Medicare discharges), bonus or relief payments, continuous improvement 
bonus payments, and payments for capital-related costs yields, in 
general, the estimate of what total Medicare payments to LTCHs would be 
in FY 2003 under the TEFRA payment system if the LTCH PPS had not been 
implemented.
    However, because sections 4413 through 4419 of the BBA of 1997, 
section 122 of the BBRA of 1999, and section 307(a)(1) of the BIPA made 
numerous changes to the TEFRA payment system, we had to make variations 
in the method described above to arrive at the estimate of FY 2003 
payments for the inpatient operating costs of each LTCH under the TEFRA 
system, depending on the participation date of the hospital. 
Specifically, we must make the requisite computations differently for 
two classes of hospitals, ``existing'' hospitals and ``new'' hospitals. 
(A detailed explanation of the provisions affecting LTCHs, established 
by each of the amendments, is found in the August 30, 2002 final rule 
that implemented the LTCH PPS (67 FR 55959).) We discuss below these 
specific BBA, BBRA, and BIPA changes, and their impact on the 
calculations of estimated FY 2003 TEFRA payments for ``existing'' and 
``new'' hospitals. As discussed in greater detail below, we would 
employ two approaches to estimate Medicare payments under the TEFRA 
system to LTCHs in FY 2003, depending on how these changes in 
calculating TEFRA

[[Page 5357]]

payments, as established by the amendments, applied to each LTCH.
    The first set of changes that we had to take into account were 
included in the BBA. The BBA made significant changes to the TEFRA 
payment methodology starting with cost reporting periods beginning on 
or after October 1, 1997. While the changes were applicable to three 
types of PPS-excluded providers (rehabilitation hospitals and units, 
psychiatric hospitals and units, and LTCHs), the following discussion 
will address the provisions of the amendments as they relate to LTCHs.
    The first change to consider under BBA is section 4414 that 
established caps on the TEFRA target amounts for cost reporting periods 
beginning on or after October 1, 1997, for LTCHs that were paid as IPPS 
excluded providers prior to that date. The cap was determined by taking 
the 75th percentile of target amounts for cost reporting periods ending 
in FY 1996 for each class of provider (rehabilitation hospitals and 
units, psychiatric hospitals and units, and LTCHs), updating that 
amount by the market basket percentage increases to FY 1998, and 
applying it to the cost reporting period beginning on or after October 
1, 1997 (62 FR 46018). The cap calculated for FY 1998 was updated by 
the applicable market basket percentages to determine the cap amounts 
for cost reporting periods beginning during FY 1999 through 2002. 
Providers subject to the 75th percentile cap were paid the lesser of 
their inpatient operating costs or the TEFRA target amount, which was 
limited by the 75th percentile cap amount (67 FR 55959). In addition, 
section 4411 of the BBA established a formula for calculating the 
update factor for FY 1999 through FY 2002 that was dependent on the 
relationship of a provider's inpatient operating costs to its ceiling 
amount based on data from the most recently available cost report. 
Section 121 of the BBRA provided that the 75th percentile cap amount 
should be wage adjusted starting with cost reporting periods beginning 
on or after October 1, 1999 and before October 1, 2002.
    The second change that we had to take into account was section 4415 
of the BBA. This provision revised the percentage factors used to 
determine the amount of bonus and relief payments for LTCHs meeting 
specific criteria. If a provider's net inpatient operating costs did 
not exceed the hospital's ceiling, a bonus payment was made to the LTCH 
(Sec.  413.40(d)(2) of the regulations). The bonus payment was the 
lower of 15 percent of the difference between the hospital's inpatient 
operating costs and the ceiling, or 2 percent of the ceiling. In 
addition, relief payments were made to providers whose net inpatient 
operating costs were greater than 110 percent of the ceiling (or the 
adjusted ceiling, if applicable). These relief payments were the lower 
of 50 percent of the costs in excess of 110 percent of the ceiling or 
(or the adjusted ceiling, if applicable) or 10 percent of the ceiling 
(or adjusted ceiling, if applicable) (Sec.  413.40(d)(3)(ii) of the 
regulations).
    The third change was an additional incentive established by section 
4415 of the BBA, the continuous improvement bonus payment (CIB) for 
providers meeting certain conditions and that kept their costs below 
the target amount. Eligibility for the CIB required that a provider had 
three full cost reporting periods as an IPPS-excluded provider prior to 
the applicable fiscal year (62 FR 46019). To qualify for a CIB, a 
provider's operating costs per discharge in the current cost reporting 
period had to be lower than the least any of the following: its target 
amount; its expected costs, that is, the lower of its target amount or 
inpatient operating costs per discharge from the previous cost 
reporting period, updated; or, its trended costs, that is, the 
inpatient operating costs per discharge from its third full cost 
reporting period, updated by the market basket percentage increase to 
the applicable fiscal year (62 FR 46019, Sec.  413.40(d)(5)(ii)(B) of 
the regulations). For providers with their third or subsequent full 
cost reporting period ending in FY 1996, trended costs are the lower of 
their inpatient operating costs per discharge or target amount updated 
forward to the current year (Sec.  413.40(d)(5)(ii)(A) of the 
regulations). The CIB payment equals the lesser of 50 percent of the 
amount by which the operating costs were less than expected costs, or, 
1 percent of the ceiling (Sec.  413.40(d)(4) of the regulations). 
Section 122 of the BBRA increased this percentage for LTCH's for FY 
2001 to 1.5 percent of the ceiling, and beginning in FY 2002, to 2 
percent of the ceiling (Sec.  413.40(d)(4)(ii) and (iii) of the 
regulations). The increase in the CIB percentage is not to be accounted 
for in the development and implementation of the LTCH PPS in accordance 
with section 307(a)(2) of BIPA.
    The fourth change that we had to take into account was section 4416 
of the BBA which significantly revised the payment methodology for 
``new'' IPPS-excluded providers. This provision applies to three 
classes of providers--psychiatric hospitals and units, rehabilitation 
hospitals and units, and LTCHs--that were not paid as excluded 
hospitals prior to October 1, 1997. The payment amount for a new 
provider for the first 12-month cost reporting period is the lower of 
its Medicare inpatient operating cost per discharge or a limit based on 
110 percent of the national median of target amounts for the same class 
of hospital for cost reporting periods ending in FY 1996, updated by 
the market basket percentage increases to the applicable period, and 
wage-adjusted. The payment limit in the second 12-month cost reporting 
period is the same 110 percent limit as for the first year (Sec.  
413.40(f)(2)(ii) of the regulations). A new provider's target amount 
would be established in its third cost reporting period by updating the 
amount paid in its second cost reporting period by the market basket 
percentage increase for hospitals and hospital units excluded from the 
IPPS, applicable to the specific year, as published annually in the 
Federal Register, which then becomes the target amount for its third 
cost reporting period. The target amount for the fourth and subsequent 
cost reporting periods is determined by updating the target amount from 
the previous cost reporting period by the applicable market basket 
percentage increase.
    Finally, two provisions under BIPA were directed specifically at 
LTCHs. Section 307(a)(1) of BIPA provided a 2 percent increase to the 
wage-adjusted 75th percentile cap for existing LTCHs for cost reporting 
periods beginning in FY 2001, and a 25 percent increase to the target 
amount for LTCHs, subject to the increased 75th percentile cap. 
However, it is important to note that in accordance with section 
307(a)(2) of BIPA, the 2 percent increase to the 75th percentile cap 
and the 25 percent increase to the target amount were not to be taken 
into account in the development and implementation of the LTCH PPS.
    In order to determine what a LTCH's estimated payments would be 
under TEFRA in FY 2003, we utilized cost report data for LTCHs from the 
Hospital Cost Reporting Information System (HCRIS) for FYs 1999 through 
2002. In addition, to determine whether a LTCH is ``new,'' the 
certification date for each LTCH was obtained from the On-line Survey & 
Certification Automated Reporting (OSCAR) file. Based on the 
certification date, a LTCH would either be a ``new'' LTCH, meaning a 
LTCH that was not paid as an excluded hospital prior to October 1, 
1997, or, an ``existing'' LTCH, meaning a LTCH that was paid as an 
excluded hospital prior to October 1, 1997. This could include a LTCH 
that was certified as an LTCH on or after October 1, 1997, but was

[[Page 5358]]

previously paid as another type of IPPS-excluded provider prior to 
October 1, 1997. Our approach to estimating Medicare payments in FY 
2003 under the TEFRA payment system varied somewhat, depending on 
whether an LTCH was ``existing'' or ``new'' (as discussed in greater 
detail below).
    Based on all these statutory changes mentioned above, the first 
step would be to estimate FY 2003 inpatient operating payments under 
the TEFRA system for ``existing'' LTCHs. ``Existing'' LTCHs are those 
receiving payment as IPPS-excluded providers in cost reporting periods 
prior to FY 1998. These LTCHs were subject to the 75th percentile cap 
on their target amounts. While section 307(a)(1) of BIPA provided for a 
2 percent increase to the 75th percentile cap amount for LTCH's for 
cost reporting periods beginning in FY 2001 and a 25 percent increase 
to the target amount for cost reporting periods beginning in FY 2001 
(subject to the limiting or cap amount determined under section 
1886(b)(3)(H) of the Act), section 307(a)(2) of BIPA precluded 
accounting for these increases in developing the LTCH PPS. In addition, 
section 122 of the BBRA increased the CIB payment percentage to 1.5 
percent for FY 2001 and 2.0 percent for FY 2002 (Sec.  413.40(d)(4)(ii) 
and (iii) of the regulations). But these increases, also, are not to be 
accounted for in the development and implementation of the LTCH PPS in 
accordance with section 307(a)(2) of BIPA. Therefore, to ensure that 
these increases would be excluded from the computations, as required by 
the statute, we estimated an existing LTCH's FY 2003 target amount by 
starting with the hospital's target amount from the FY 2000 cost 
report, the year prior to when these increases were effective. Target 
amounts and payments for FY 2003 were simulated using the FY 2000 
target amount in the hospital's cost report and updating the target 
amount for each subsequent cost reporting period by the applicable 
rate-of-increase percentage as described in Sec.  413.40(c)(3)(vii) 
through FY 2002. The target amount from FY 2002 is updated by the 
forecasted market basket percentage increase of 3.5 percent to arrive 
at the FY 2003 target amount (Sec.  413.40(c)(3)(viii)). (Note, the 
forecasted increase in the excluded hospital market basket for FY 2003 
of 3.5 percent was the applicable rate-of-increase percentage used to 
update TEFRA target amounts in accordance with Sec.  413.40(c)(3)(viii) 
in the FY 2003 IPPS final rule (August 1, 2002, 67 FR 50289)). Based on 
more recent data, our Office of the Actuary currently estimates an 
increase of 4.2 percent in the excluded hospital market basket for FY 
2003, which we used to update LTCHs' FY 2002 costs to FY 2003, as 
described below.) In a small number of cases where FY 2002 operating 
cost data were not available, we used operating cost data from the most 
recent year available and trended it forward to FY 2003. In addition, 
we estimated FY 2003 bonus or relief payments without the inclusion of 
the 2 percent and 25 percent increases to the cap amount and target 
amount, respectively, and without the 1.5 percent and 2.0 percent 
increases to the CIB payments, consistent with section 307(a)(2) of 
BIPA as discussed above.
    In addition, since comparisons are made between the target amount 
and Medicare inpatient operating costs to determine bonus or relief 
payments, we estimated FY 2003 operating costs for each LTCH by 
updating its FY 2002 operating costs by the actual percentage increase 
in operating costs for PPS-excluded hospitals from FY 2002 to FY 2003 
(4.2 percent, as determined by OACT). The 3.5 percent market basket 
increase used to update the TEFRA target amounts from FY 2002 to FY 
2003 was the forecast increase used at that time based on the most 
recent information from OACT, at that time. However, because we now 
have more recent data available for estimating the market basket 
increase for IPPS-excluded hospitals from FY 2002 to FY 2003, we are 
using that more recent data which OACT currently estimates that the 
IPPS-excluded hospital market basket increase from FY 2002 to FY 2003 
is 4.2 percent. As discussed earlier, we estimated the FY 2003 
operating costs using FY 2002 costs rather than use the costs reported 
on the FY 2003 cost report.
    The 75th percentile cap for LTCHs for FY 2002, without the 2 
percent and 25 percent increases to the cap and target amount, 
respectively, was $30,783 for the wage-index adjusted labor-related 
share, and $12,238 for the nonlabor-related share. If a LTCH's costs 
and hospital-specific target amount were above the 75th percentile cap, 
Medicare's payment under the TEFRA system would be the wage-index 
adjusted cap amount. If under our payment model a LTCH's estimated FY 
2002 TEFRA payment would have been limited by the wage-adjusted 75th 
percentile cap in FY 2002, that amount would be updated by the 
forecasted market basket percentage increase (of 3.5 percent) to FY 
2003 to determine the LTCH's FY 2003 target amount that was used to 
estimate its TEFRA payment amount for FY 2003.
    The second approach that we used to estimate FY 2003 hospital 
operating payments under the TEFRA system applied to ``new'' LTCHs. A 
``new'' LTCH is one that was first paid as an IPPS excluded hospital on 
or after October 1, 1997. For a ``new'' LTCH, payment in the hospital's 
first 12-month cost reporting period is the lower of its Medicare net 
inpatient operating costs per discharge or the wage-adjusted 110 
percent median amount determined for that particular year (Sec.  
413.40(f)(2)(ii) of the regulations). For the hospital's second 12-
month cost reporting period, payment is the lower of their costs, or 
the same 110 percent median amount that was used in the first cost 
reporting period, that is, it is not updated. The hospital's ``target 
amount'' is established in the third cost reporting period by updating 
the per discharge amount that was paid in the prior cost reporting 
period by the estimated market basket percentage increase for hospitals 
and hospital units excluded from the IPPS, applicable to the specific 
year, as published annually in the Federal Register. Therefore, if the 
LTCH was paid its costs in the previous cost reporting period because 
costs were lower than the 110 percent median amount, the hospital's 
cost per discharge for the second cost reporting period is updated and 
becomes the target amount for the hospital's third cost reporting 
period. Target amounts for subsequent cost reporting periods are 
determined by updating the previous year's target amount by the 
applicable market basket percentage increase.
    New LTCHs with their first 12-month cost reporting period beginning 
in FY 1998, would have had a target amount calculated under section 
1886(b)(7)(A)(ii) of the Act, in FY 2000. Therefore, as with the 
``existing'' LTCH's, in estimating the FY 2003 target amount, we used 
the target amount from the FY 2000 cost report for those LTCHs and 
update that target amount by the applicable estimated market basket 
percentage increases as published annually in the Federal Register for 
the IPPS final rule, without the 25 percent increase, to FY 2003. For 
LTCH's with their first 12-month cost reporting period beginning in FY 
1999, we used the lower of their costs or target amount from their FY 
2000 cost report, and updated that amount by the applicable estimated 
market basket percentage increase to establish the target amount in FY 
2001, without the 25 percent increase. From this point, we would 
continue to update that target amount by the estimated market basket

[[Page 5359]]

percentage increases to FY 2003. It is necessary to compute an 
estimated target amount for LTCHs that are ``new'' in FY 1999 in order 
to eliminate the potential inclusion of the increase to the target 
amounts provided for by section 307(a)(1) of BIPA (consistent with the 
statute).
    The 25 percent increase (under section 307(a) of the BIPA) to the 
target amount was not an issue for LTCH's with their first 12-month 
cost reporting period beginning in FYs 2000, 2001, and 2002 because 
they would not have a ``target amount'' based on sections 
1886(b)(7)(A)(ii) of the Act, in FY 2001. Rather, for these LTCHs, we 
would have proposed to determine the estimated payment amount for their 
first 12-month cost reporting period by looking at their certification 
date from the OSCAR file, the applicable 110 percent median amount 
(adjusted by their wage-index) and their costs from the applicable cost 
report, and then proceed in accordance with the policy in Sec.  
413.40(f)(2)(ii) of the regulations, to arrive at estimated FY 2003 
TEFRA payments.
    In addition to the TEFRA payments for operating costs, and any 
bonus or relief payments made, we also added $10 million as an estimate 
of the CIB payments that would have been made in FY 2003 under the 
TEFRA payment system. We estimated this payment by using actual CIB 
payments from the cost reports for FYs 1999 and 2000 as they would not 
include the statutory increases to the target amount as discussed 
above, and recalculated CIB payments for FYs 2001 and 2002 based on 
cost report data. Based on these historical CIB payments, we estimated 
that CIB payments in FY 2003 would have been approximately $10 million. 
Just as the TEFRA payments and bonus and relief payments had to be 
recalculated in particular years to eliminate percentage increases that 
were not to be included in our budget neutrality calculations, it was 
necessary to recalculate the CIB payments in FYs 2001 and 2002 to 
eliminate the percentage increases to these payments as provided for 
under section 122 of BBRA, but not to be accounted for in the 
development of the LTCH in accordance with section 307(a)(2) of BIPA.
    As we discussed above, the second step in estimating total payments 
under the TEFRA payment system is to estimate each LTCH's payment per 
discharge for capital-related costs. Under the TEFRA system, in 
accordance with section 1886(g) of the Act, Medicare allowable capital 
costs are paid on a reasonable cost basis. Therefore, we took each 
LTCH's payment for capital-related costs directly from the FY 2002 cost 
report and updated it for inflation using the FY 2003 capital excluded 
hospital market basket estimate of 0.7 percent, consistent with the 
methodology used in the August 30, 2002 final rule (67 FR 56032) in 
which we established the initial standard Federal rate. Thus, we 
determined capital-related costs per case using capital cost data from 
Worksheets D, Parts I and II, and total Medicare discharges for the 
cost reporting period from worksheet S-3. (We note that since payments 
for capital-related costs are on a reasonable-cost basis, capital 
payments were the same for ``existing'' and ``new'' LTCHs.)
    Once we have estimated total TEFRA payments as the sum of each 
LTCH's estimated operating and capital payment per case, it is 
necessary to estimate FY 2003 payments under the LTCH PPS. As we 
discussed above, in evaluating the one-time prospective adjustment at 
Sec.  412.523(d)(3), we believe that the best approach is to use FY 
2002 LTCH claims data as a proxy for estimating FY 2003 LTCH PPS 
payments. We note (as explained below) that we used the same FY 2002 
LTCH MedPAR data that was used to develop the FY 2004 LTC-DRG relative 
weights in the FY 2004 IPPS final rule (68 FR 45376). As we discussed 
in that final rule, there is a data problem with the FY 2002 claims 
data for LTCHs where multiple bills for the stay were submitted. 
Specifically, given the long stays at LTCHs, some providers had 
submitted multiple bills for payment under the reasonable cost-based 
reimbursement system for the same stay. In certain LTCHs, hospital 
personnel apparently reported a different principal diagnosis on each 
bill since, under the reasonable cost-based (TEFRA) reimbursement 
system, payment was not dependent upon principal diagnosis, as it is 
under a DRG-based PPS system. As a result of this billing practice, we 
discovered that only data from the final bills were being extracted for 
the MedPAR file. Therefore, it was possible that the original MedPAR 
file was not receiving the correct principal diagnosis. In that same 
IPPS final rule, we discussed how we addressed this problem in the LTCH 
FY 2002 MedPAR data when we used that data to determine the FY 2004 
LTC-DRG relative weights. As stated above, for the evaluation of the 
one-time budget neutrality adjustment at Sec.  412.523(d)(3) in this 
proposed rule, we used the same ``corrected'' FY 2002 LTCH MedPAR data 
that was used to develop the FY 2004 LTC-DRG relative weights. For the 
reader's benefit, we are providing a summary of how we addressed the 
multiple bill problem in the FY 2002 LTCH MedPAR data below. As we 
explained in the FY 2004 IPPS final rule (68 FR 45376), we addressed 
this problem by identifying all LTCH cases in the FY 2002 MedPAR file 
for which multiple bills were submitted. For each of these cases, 
beginning with the first bill and moving forward consecutively through 
subsequent bills for that stay, we recorded the first unique diagnosis 
codes up to 10 and the first unique procedure codes up to 10. We then 
used these codes to appropriately group each LTCH case to a LTC-DRG for 
FY 2004.
    We estimated FY 2003 LTCH PPS payments using the same general 
methodology that we used to estimate FY 2003 payments under the LTCH 
PPS (without a budget neutrality adjustment) when we determined the 
initial standard Federal rate in the August 30, 2002 final rule (67 FR 
56032). Specifically, we estimated FY 2003 LTCH PPS payments for each 
LTCH by simulating payments on a case-by-case basis by applying the 
final FY 2003 payment policies established in the August 30, 2002 final 
rule that implemented the LTCH PPS (67 FR 55954) based on the LTCH 
case-specific discharge information from the FY 2002 MedPAR files (as 
explained above), and we also used LTCH provider-specific data from the 
FY 2003 provider specific file (PSF), as these were the data used by 
FIs to make LTCH payments during the first year of the LTCH PPS (FY 
2003). We used the FY 2003 LTC-DRG Grouper (Version 22.0) software 
program, relative weights, and average length of stay (see 67 FR 55979 
through 55995); we made adjustments for differences in area wage levels 
established for FY 2003 as set forth at Sec.  412.525(c) using the 
appropriate phase-in wage index values and cost-of-living for Alaska 
and Hawaii as set forth at Sec.  412.525(b) established for FY 2003 
(see 67 FR 56015 through 56020 and 56022, respectively); we made 
adjustments for short-stay outlier cases based on the method for 
determining payment applicable for discharges occurring during FY 2003 
in accordance with Sec.  412.529(c)(1) (see 67 FR 55975 and 55995-
56002); and we included additional payments for high cost outlier cases 
as initially implemented in accordance with former Sec.  412.525(a) for 
determining payments for discharges occurring in FY 2003 and the FY 
2003 fixed-loss amount of $24,450 (see 67 FR 56023). (We note that 
correctly billed interrupted stay cases under Sec.  412.531 are single 
LTCH cases in the MedPAR files, and therefore, we estimated a

[[Page 5360]]

single LTCH PPS payment for those cases.) For purposes of this 
calculation, we simulated case-by-case payments for each LTCH as if it 
were paid based on 100 percent of the standard Federal rate in FY 2003 
rather than the transition blend methodology set forth at Sec.  
412.533. To determine total estimated PPS payments for all LTCHs, we 
summed the individual estimated LTCH PPS payments for each LTCH.
    The next step we did to evaluate a potential one-time adjustment 
under Sec.  412.523(d)(3) was to determine a case-weighted average 
estimated TEFRA payment, consistent with the methodology used when we 
determined the initial standard Federal rate in the August 30, 2002 
final rule (68 FR 56032). This step is necessary in order to determine 
if there is any difference between estimated total TEFRA payments and 
estimated LTCH PPS payments in FY 2003. Each LTCH's estimated total FY 
2003 TEFRA payment per discharge was determined by summing its 
estimated FY 2003 operating and capital payments under the TEFRA 
payment system based on FY 2002 cost report data (as described above), 
and dividing that amount by the number of discharges from the FY 2002 
cost report data. Next, we determined each LTCH's average estimated 
TEFRA payment weighted for its number of discharges in the FY 2002 
MedPAR file (for the purpose of estimating FY 2003 LTCH PPS payments, 
as discussed above) by multiplying its average estimated total TEFRA 
payment per discharge by its number of discharges in the FY 2002 MedPAR 
file. We then estimated total case-weighted TEFRA payments by summing 
each LTCH's (MedPAR) case-weighted estimated FY 2003 TEFRA payments. 
This estimated FY 2003 total TEFRA payment is compared to the estimated 
FY 2003 total LTCH PPS payment in order to determine whether a one-time 
budget neutrality adjustment would be appropriate. (As discussed in 
greater detail above, we are determining both estimated total FY 2003 
TEFRA payments and estimated total FY 2003 LTCH PPS payments based on 
FY 2002 cost report and claims data, respectively.) Adjusting our 
estimate of FY 2003 TEFRA payments for the number of discharges that we 
are using to estimate FY 2003 LTCH PPS payments ensures that the 
comparison of estimated aggregate FY 2003 TEFRA payments to estimated 
aggregate FY 2003 LTCH PPS payments is based on the same number of LTCH 
discharges.
    Using the methodology and data described above, we have calculated 
that estimated FY 2003 LTCH PPS payments are approximately 2.5 percent 
higher than estimated payments to the same LTCHs in FY 2003 if the LTCH 
PPS had not been implemented (that is, estimated total FY 2003 TEFRA 
payments). This analysis was based on approximately 91,300 LTCH cases 
for 250 LTCHs. As discussed above, we would have proposed that any 
difference greater than or equal to 0.25 percentage points 
``significant'' for purposes of determining whether the one-time budget 
neutrality adjustment provided under Sec.  412.523(d)(3) may be 
warranted. Although we project that estimated FY 2003 LTCH PPS payments 
are approximately 2.5 percent higher than estimated FY 2003 TEFRA 
payments, reducing the standard Federal rate by 2.5 percent would not 
``maintain budget neutrality'' for FY 2003 (that is, estimated FY 2003 
LTCH PPS payments would not be equal to estimated FY 2003 TEFRA 
payments) because a considerable number of LTCH discharges are 
projected to have received a LTCH PPS payment in FY 2003 based on the 
estimated cost of the case (rather than a payment based on the standard 
Federal rate) under the payment adjustment for short-stay outlier (SSO) 
cases at Sec.  412.529. Specifically, our payment data indicate that 
nearly 20 percent of estimated FY 2003 LTCH PPS payments are SSO 
payments that were paid based on estimated cost and not based on the 
LTCH PPS standard Federal rate. These SSO cases that receive a payment 
based on the estimated cost of the case are generally unaffected by any 
changes to the Federal rate because the estimated cost of the case is 
determined by multiplying the Medicare allowable charges by the LTCH's 
cost-to-charge ratio (see Sec.  412.529(d)(2)). In other words, if we 
were to reduce the Federal rate by 2.5 percent, estimated total FY 2003 
LTCH PPS payments would still be greater than estimated total FY 2003 
TEFRA payments, and therefore would not be budget neutral. This is 
because the estimated LTCH PPS payments for those SSO cases that in FY 
2003 were estimated to have been paid 120 percent of the estimated cost 
of the case generally are not affected (that is, in this case, not 
lowered) by any budget neutrality factor that would be applied to the 
standard Federal rate since those payments are not derived from the 
Federal rate (as explained above). Therefore, it would be necessary to 
propose to offset the standard Federal rate by a factor that is larger 
than 2.5 percent in order to ensure that estimated total FY 2003 LTCH 
PPS payments would be equal to estimated total FY 2003 TEFRA payments 
in order to ``maintain budget neutrality.'' To determine the necessary 
adjustment factor that would need to be applied to the standard Federal 
rate in order to ``maintain budget neutrality,'' we simulated FY 2003 
LTCH PPS payments using the same payment simulation model discussed 
above (that we used to estimate FY 2003 LTCH PPS payments without a 
budget neutrality factor). Using iterative payment simulations using 
the data from the 250 LTCHs in our database, we determined that a 
factor of 0.9625 (that is, approximately 3.75 percent (rather than 2.5 
percent)) would need to be applied to the standard Federal rate in 
order to make estimated total FY 2003 LTCH PPS payments equal to 
estimated total FY 2003 TEFRA payments.
    In the absence of section 114(c)(4)of the Medicare, Medicaid, and 
SCHIP Extension Act of 2007, we would have proposed to employ this 
methodology in determining whether it would have been appropriate to 
propose a one-time budget neutrality adjustment. As the discussion 
above indicates, that analysis suggests that an adjustment of 3.75 
percent to the standard Federal rate would have been warranted. We 
expect to address the issue again when it is closer to the time section 
114(c)(4) of the MMSEA permits us to implement a one-time adjustment 
under Sec.  412.523(d)(3). In the meantime, we welcome comments on the 
methodology that we have described. We would take these comments into 
account in proposing to implement a one-time budget neutrality 
adjustment on or after December 29, 2010. As noted above, we will 
respond to any comments on our proposed changes to the methodology for 
the one-time budget neutrality adjustment and proposed change to 
implement the requirements of section 114(c)(4) of Public Law 110-173.

E. Proposed Standard Federal Rate for the 2008 LTCH PPS Rate Year

1. Background
    At Sec.  412.523(c)(3)(ii), for LTCH PPS rate years beginning RY 
2004 through RY 2006, we updated the standard Federal rate by a rate 
increase factor to adjust for the most recent estimate of the increases 
in prices of an appropriate market basket of goods and services for 
LTCHs. We established the policy of annually updating the standard 
Federal rate because at that time we believed that was the most 
appropriate method for updating the LTCH PPS standard Federal rate 
annually for years after FY 2003. When we moved the date of the annual 
update of the LTCH PPS from

[[Page 5361]]

October 1 to July 1 in the RY 2004 LTCH PPS final rule (68 FR 34138), 
we revised Sec.  412.523(c)(3)accordingly. At that time, we believed 
that was the most appropriate method for updating the LTCH PPS standard 
Federal rate annually for years after RY 2004.
    In the RY 2007 LTCH PPS final rule (71 FR 27818), we explained that 
rather than solely using the most recent estimate of the LTCH PPS 
market basket as the basis of the update factor for the Federal rate 
for RY 2007, we believed it was appropriate to adjust the Federal rate 
to account for the changes in coding practices (rather than patient 
severity) as indicated by our ongoing monitoring activities. We 
established at Sec.  412.523(c)(3)(iii) that the update to the standard 
Federal rate for the 2007 LTCH PPS rate year was zero percent, based on 
the most recent estimate of the LTCH PPS market basket at the time 
which was offset by an adjustment to account for changes in case-mix in 
prior periods due to changes in coding practices rather than increased 
patient severity in FY 2004. Therefore, effective from July 1, 2006 
through June 30, 2007, the standard rate was $38,086.04 (71 FR 27818). 
For the following year, we also considered changes in coding practices 
(rather than patient severity) in establishing the update to the 
Federal rate for the 2008 LTCH PPS rate year. In the RY 2008 final rule 
(72 FR 26887 through 27890), we adjusted the Federal rate based on the 
most recent estimate of market basket (3.2 percent) and an adjustment 
to account for changes in coding practices (2.49 percent) in FY 2005. 
Accordingly, we established at Sec.  412.523(c)(3)(iv) that the update 
to the standard Federal rate for RY 2008 was 0.71 percent. 
Consequently, in the RY 2008 final rule, we established the LTCH PPS 
standard Federal rate, effective from July 1, 2007 through June 30, 
2008, of $38,356.45 (see 72 FR 26890).
    As stated in section I.A. of this preamble, section 114(e)(1) of 
the Medicare, Medicaid, and SCHIP Extension Act of 2007, enacted on 
December 29, 2007 revises the base rate for RY 2008. Specifically, 
section 114(e)(1) of Public Law 110-173 adds a new subsection to the 
Act at 1886(m)(2), which provides that the base rate for RY 2008 
``shall be the same as the base rate for discharges for the hospital 
occurring during the rate year ending in 2007.'' In addition, section 
114(e)(2) of Public Law 110-173 indicates that section 1886(m)(2) of 
the Act ``shall not apply to discharges occurring on or after July 1, 
2007, and before April 1, 2008'' (that is, the first 9 months of RY 
2008). We note that the statute uses the term ``base rate,'' which is 
an undefined term in Sec.  1886(m) of the ACT and in 42 CFR Part 412, 
subpart O. We are interpreting that term to mean the standard Federal 
rate because we believe the Congress meant to eliminate the 0.71 
percent update from the RY 2008 standard Federal rate.
    If the term ``base rate'' used in the statute refers to the 
standard Federal rate, then the standard Federal rate for RY 2008 would 
be the same as the standard Federal rate for RY 2007 and the 0.71 
percent update finalized in the RY 2008 final rule would be reversed. 
We do not believe that the term ``base rate'' could refer to the 
``unadjusted rate'' (that is, to determine the standard Federal rate 
for any given rate year, the previous year's standard Federal rate, 
referred herein as the ``unadjusted rate'', is updated by the current 
year's update factor.) If the interpretation of ``base rate'' is the 
``unadjusted rate,'' it would render meaningless the provision at the 
section 114(e)(1) of the MMSEA and Congress does not legislate a 
nullity. The provision would be meaningless under such an 
interpretation because even though the unadjusted rate for RY 2008 
would be the same as the unadjusted rate for RY 2007, this unadjusted 
rate must still be updated by 0.71 percent, and doing so would result 
in the same standard Federal rate for RY 2008 as was adopted in the RY 
2008 final rule. (The unadjusted rate must be updated by 0.71 percent 
in order to determine the standard Federal rate because it is the 
standard Federal rate that is the basis for Federal prospective LTCH 
PPS payments.) Consequently, LTCH PPS payments would be unaffected by 
section 114(e)(1) of the Medicare, Medicaid, and SCHIP Extension Act of 
2007. We explain below why RY 2008 LTCH PPS payments would be 
unaffected by section 114(e)(1) of Public Law 110-173 if ``base rate'' 
means ``unadjusted rate.'' Specifically, if ``base rate'' means the 
``unadjusted rate,'' the RY 2007 ``base rate'' (that is, $38,086.04) 
would be the same as the standard Federal rate for RY 2007 (also 
$38,086.04) since we established a zero percent update for RY 2007. 
Consequently, if ``base rate'' is interpreted to mean ``unadjusted 
rate,'' the ``unadjusted rate'' for RY 2008 ($38,086.04) would be the 
same as the RY 2007 ``unadjusted rate'' ($38,086.04). The RY 2008 
``unadjusted rate'' of $38,086.04 would subsequently be updated by the 
0.71 percent update factor finalized in the RY 2008 final rule, 
resulting in a standard Federal rate for RY 2008 of $38,356.45, which 
is the same standard Federal rate that was actually finalized in the RY 
2008 final rule and which would continue to be the standard Federal 
rate for RY 2008 even if section 114(e)(1) of MMSEA had not been 
enacted. Since as we noted above, Congress does not legislate a 
nullity, we therefore believe that the term ``base rate'' used in 
section 114(e)(1) of MMSEA refers to the standard Federal rate and not 
the ``unadjusted rate.'' In subsequent sections of this preamble, we 
shall be using the term standard Federal rate instead of ``base rate'' 
when referencing the provision in section 114(e)(1) of MMSEA in order 
to avoid further confusion. As noted above, the standard Federal rate 
for RY 2007 was $38,086.04 (71 FR 27818).
2. Proposed Standard Federal Rate for the 2009 LTCH PPS Rate Year
    In the RY 2008 LTCH PPS final rule (72 FR 26890), we established a 
standard Federal rate of $38,356.45 for the 2008 LTCH PPS rate year 
that was based on the best available data and policies established in 
that final rule. As discussed above, the Medicare, Medicaid, and SCHIP 
Extension Act of 2007, enacted on December 29, 2007, revises the 
standard Federal rate for RY 2008 while specifying that this rate 
``shall not apply to discharges occurring on or after July 1, 2007, and 
before April 1, 2008'' (that is, the first 9 months of RY 2008). 
Specifically, section 114(e)(1) of MMSEA provides that under the new 
1886(m)(2) to the Act the standard Federal rate for RY 2008 shall be 
the same as the standard Federal rate for RY 2007 (which shall not 
apply to discharges occurring before April 1, 2008). Thus, the standard 
Federal rate for RY 2008 will be $38,086.04 (the same as standard 
Federal rate for 2007). In this proposed rule, consistent with our 
historical practice, we are proposing to update the standard Federal 
rate from the previous year ($38,086.04) to determine the proposed 
standard Federal rate for RY 2009. Under the broad authority conferred 
upon the Secretary by section 123 of the BBRA as amended by section 
307(b) of the BIPA, we are proposing an annual update to the standard 
Federal rate for the proposed 15-month 2009 rate year based on the most 
recent LTCH PPS market basket estimate of 3.5 percent, as discussed 
above in section IV.C. of the preamble of this proposed rule, and an 
adjustment of 0.9 percent to account for the increase in case-mix in a 
prior period (FY 2006) that resulted from changes in coding practices 
rather than an increase in patient severity.
    As we discussed in greater detail in the RY 2007 and RY 2008 LTCH 
PPS

[[Page 5362]]

final rules (71 FR 27819 through 27827 and 72 FR 26887 through 26890, 
respectively), while we continue to believe that an update to the LTCH 
PPS Federal rate year should be based on the most recent estimate of 
the LTCH PPS market basket, we believe it is appropriate that the rate 
be offset by an adjustment to account for any changes in coding 
practices that do not reflect increased patient severity. Such an 
adjustment protects the integrity of the Medicare Trust Funds by 
ensuring that the LTCH PPS payment rates better reflect the true costs 
of treating LTCH patients (71 FR 27819 through 27827).
    We continue to believe that a proposed update to the LTCH PPS 
Federal rate year should be based on the most recent estimate of the 
LTCH PPS market basket, offset if appropriate by an adjustment to 
account for changes in coding practices that do not reflect increased 
patient severity. Furthermore, in the FY 2008 IPPS final rule, we did 
not finalize the proposed case-mix budget neutrality factor for the 
adoption of the severity adjusted MS-LTC-DRG patient classification 
system to the FY 2008 MS-LTC-DRG relative weights. We stated in that 
rule that since we have an established mechanism to adjust 
prospectively LTCH payments to account for the effect of changes in 
coding from a previous year and documentation which is based on actual 
LTCH data, and because at the time of the final rule we were unable to 
determine an appropriate adjustment factor applicable to LTCHs, we 
believed it was appropriate to continue using the established process 
rather than making a prospective adjustment based on an estimate of 
projected LTCH specific case-mix change due to improved coding and 
documentation. We also stated that consistent with past LTCH payment 
policy, we could propose to make future adjustments to account for 
improvements in coding and documentation that do not reflect real 
changes in case mix during these years that we are implementing MS-LTC-
DRGs. We also stated in that final rule that we continue to believe 
more accurate and complete documentation and coding will occur, and 
that we will continue to monitor LTCHs' response to the MS-LTC-DRG 
transition and would propose an adjustment factor to LTCHs to account 
prospectively for coding and documentation changes if CMS is able to 
estimate an appropriate adjustment factor applicable to LTCHs. In 
determining the proposed update to the standard Federal rate for the 
2009 LTCH PPS rate year, we performed a CMI analysis using the most 
recent available LTCH claims data (FY 2006 MedPAR files) and estimated 
the observed CMI change for FY 2006 to be 1.9 percent (based on the 
most recent available LTCH case-mix data from FY 2005 compared to FY 
2006). We continue to believe, as discussed and for the same reasons 
stated in the RY 2008 final rule (72 FR 26888 through 26890), that it 
is appropriate to utilize the estimate of real CMI increase of 1.0 
percent, based on the well-established RAND study referred to in the RY 
2008 final rule, as the proxy for the portion of the observed 1.9 
percent CMI increase from FY 2005 to FY 2006 that represents real CMI 
changes for use in determining the proposed RY 2009 Federal rate 
update. (A more detailed discussion on the use of the RAND study 
estimate for real CMI change can be found in the RY 2008 final rule 
appearing in the Federal Register on May 11, 2007. (72 FR 26887 through 
26890)). Accordingly, we believe that 0.9 percent (1.9 - 1.0 = 0.9) of 
the observed 1.9 percent CMI increase from FY 2005 to FY 2006 reflects 
CMS increase that is due to changes in coding practices (rather than 
patient severity).
    At this time, the most recent estimate of the LTCH PPS market 
basket is 3.5 percent as discussed above in section IV.C.2. of this 
proposed rule. We are proposing to update the standard Federal Rate for 
RY 2009 based on the full LTCH PPS market basket estimate of 3.5 
percent and a proposed adjustment to account for the increase in case-
mix in the prior period (FY 2006) that resulted from changes in coding 
practices of 0.9 percent. Therefore, the proposed update factor to the 
standard Federal rate for RY 2009 is 2.6 percent (3.5 - 0.9 = 2.6). 
That is, under the broad authority conferred upon the Secretary under 
the BBRA and the BIPA, we are proposing to specify under Sec.  
412.523(c)(3)(v), that, for discharges occurring on or after July 1, 
2008 and on or before September 30, 2009, the standard Federal rate 
from the previous year would be updated by 2.6 percent. In determining 
the proposed standard Federal rate for RY 2009, we are applying the 
proposed 2.6 percent update to the RY 2008 Federal rate of $38,086.04), 
which is the same standard Federal rate for discharges occurring during 
the rate year ending in 2007, consistent with section 114(e)(1) of the 
Medicare, Medicaid, and SCHIP Extension Act of 2007. Consequently, the 
proposed standard Federal rate for RY 2009 would be $39,076.28.
    We also propose that if more recent data becomes available (such as 
a more recent estimate of the LTCH PPS market basket), we would use 
that data, if appropriate, to determine the update to the standard 
Federal rate for the RY 2009 final rule, and thus, the Federal rate 
update noted in the proposed regulation text at Sec.  412.523(c)(3)(v) 
could change.

F. Calculation of Proposed LTCH Prospective Payments for the 2009 LTCH 
PPS Rate Year

1. Proposed Adjustment for Area Wage Levels
a. Background
    Under the authority of section 123 of the BBRA as amended by 
section 307(b) of the BIPA, we established an adjustment to the LTCH 
PPS Federal rate to account for differences in LTCH area wage levels at 
Sec.  412.525(c). The labor-related share of the LTCH PPS Federal rate, 
currently estimated by the FY 2002-based RPL market basket (as 
discussed in greater detail in section IV.C.1. of this preamble), is 
adjusted to account for geographic differences in area wage levels by 
applying the applicable LTCH PPS wage index. The applicable LTCH PPS 
wage index is computed using wage data from inpatient acute care 
hospitals without regard to reclassification under sections 1886(d)(8) 
or 1886(d)(10) of the Act.
    As we discussed in the August 30, 2002 LTCH PPS final rule (67 FR 
56015), when the LTCH PPS was implemented, we established a 5-year 
transition to the full wage adjustment. The wage index adjustment was 
completely phased-in beginning with cost reporting periods beginning in 
FY 2007. Therefore, for cost reporting periods beginning on or after 
October 1, 2006, the applicable LTCH wage index values are the full 
(five-fifths) LTCH PPS wage index values calculated based on acute-care 
hospital inpatient wage index data without taking into account 
geographic reclassification under sections 1886(d)(8) and (d)(10) of 
the Act. For additional information on the phase-in of the wage index 
adjustment under the LTCH PPS, refer to the August 30, 2002 LTCH PPS 
final rule (67 FR 56017 through 56019) and the RY 2008 LTCH PPS final 
rule (72 FR 26891).
b. Proposed Updates to the Geographic Classifications/Labor Market Area 
Definitions
(1) Background
    As discussed in the August 30, 2002 LTCH PPS final rule, which 
implemented the LTCH PPS (67 FR 56015 through 56019), in establishing 
an adjustment for area wage levels under Sec.  412.525(c), the labor-
related portion of a LTCH's Federal prospective payment is adjusted by 
using an appropriate wage index based on the

[[Page 5363]]

labor market area in which the LTCH is located. In the RY 2006 LTCH PPS 
final rule (70 FR 24184 through 24185), in regulations at Sec.  
412.525(c), we revised the labor market area definitions used under the 
LTCH PPS effective for discharges occurring on or after July 1, 2005 
based on the Office of Management and Budget's (OMB's) Core Based 
Statistical Area (CBSA) designations based on 2000 Census data. We made 
this revision because we believe that those new CBSA-based labor market 
area definitions will ensure that the LTCH PPS wage index adjustment 
most appropriately accounts for and reflects the relative hospital wage 
levels in the geographic area of the hospital as compared to the 
national average hospital wage level. As set forth in existing Sec.  
412.525(c)(2), a LTCH's wage index is determined based on the location 
of the LTCH in an urban or rural area as defined in Sec.  
412.64(b)(1)(ii)(A) through (C). An urban area under the LTCH PPS is 
currently defined at Sec.  412.64(b)(1)(ii)(A) and (B). Under Sec.  
412.64(b)(1)(ii)(C), a rural area is defined as any area outside of an 
urban area.
    We note that these are the same CBSA-based designations implemented 
for acute care hospitals under the IPPS at Sec.  412.64(b) effective 
October 1, 2004 (69 FR 49026 through 49034). For further discussion of 
the labor market area (geographic classification) definitions currently 
used under the LTCH PPS, see the RY 2006 LTCH PPS final rule (70 FR 
24182 through 24191).
(2) Proposed Update to the CBSA-based Labor Market Area Definitions
    On December 18, 2006, OMB announced the inclusion of two new CBSAs 
and the revision of designations for six areas (OMB Bulletin No. 07-
01). This OMB bulletin is available on the OMB Web site at http://www.whitehouse.gov/omb/bulletins/fy2007/b07-01.pdf. The two new CBSAs 
outlined in this bulletin are as follows:
     Lake Havasu-Kingman, Arizona (CBSA code 29420). This CBSA 
comes from Mohave County, Arizona.
     Palm Coast, Florida (CBSA code 37380). This CBSA comes 
from Flager County, Florida.
    The six revised CBSA designations outlined in this bulletin are as 
follows:
     Mauldin, South Carolina and Easley, South Carolina qualify 
as new principal cities of the Greenville-Mauldin-Easley, South 
Carolina CBSA (CBSA code 24860).
     Conway, Arkansas qualifies as a new principal city of the 
Little Rock-North Little Rock-Conway, Arkansas CBSA (CBSA code 30780).
     Goleta, California qualifies as a new principal city of 
the Santa Barbara-Santa Maria-Goleta, California CBSA (CBSA code 
42060).
     Franklin, Tennessee qualifies as a new principal city of 
the Nashville-Davidson-Murfreesboro-Franklin, Tennessee CBSA (CBSA code 
34980).
     Fort Pierce, Florida no longer qualifies as a principal 
city of the Port St. Lucie-Fort Pierce, Florida CBSA; the new 
designation is Port St. Lucie, Florida CBSA (CBSA code 38940).
     Essex County, Massachusetts Metropolitan Division was 
renamed as the Peabody, Massachusetts Metropolitan Division, which 
changed the CBSA code from 21604 to 37764.
    We note that these six revised CBSA designations made in OMB 
Bulletin No. 07-01 do not change the composition (constituent counties) 
of the affected CBSAs; they only revise the CBSA titles (and the CBSA 
code for the CBSA that consists of Essex County, MA).
    In this proposed rule, under the broad authority conferred upon the 
Secretary by section 123 of the BBRA, as amended by section 307(b) of 
BIPA to determine appropriate adjustments under the LTCH PPS, we are 
proposing to apply these changes to the current CBSA-based labor market 
area definitions and geographic classifications used under the LTCH PPS 
effective for discharges occurring on or after July 1, 2008. We believe 
these revisions to the LTCH PPS CBSA-based labor market area 
definitions, which are based on the most recent available data, would 
ensure that the LTCH PPS wage index adjustment most appropriately 
accounts for and reflects the relative hospital wage levels in the 
geographic area of the hospital as compared to the national average 
hospital wage level. (We note that we are currently not aware of any 
LTCHs located in the two new proposed CBSAs (that is, proposed CBSA 
29420 and proposed CBSA 37380), and as discussed above, the six 
proposed revisions to the CBSA designations would only revise the CBSA 
titles (and the CBSA code for the CBSA that consists of Essex County, 
MA).) Accordingly, the proposed RY 2009 LTCH PPS wage index values 
presented in Tables 1 and 2 in the Addendum of this proposed rule were 
calculated based on the proposed revisions to the CBSA-based labor 
market area definitions described above. We also note that these 
revisions to the CBSA-based designations were adopted under the IPPS 
effective beginning October 1, 2007 (72 FR 47308 through 47309).
(3) Clarification of New England Deemed Counties
    We are also taking this opportunity to address the change in the 
treatment of ``New England deemed counties'' (that is, those counties 
in New England listed in Sec.  412.64(b)(1)(ii)(B) that were deemed to 
be parts of urban areas under section 601(g) of the Social Security 
Amendments of 1983) that was made in the FY 2008 IPPS final rule with 
comment period. These counties include the following: Litchfield 
County, Connecticut; York County, Maine; Sagadahoc County, Maine; 
Merrimack County, New Hampshire; and Newport County, Rhode Island. Of 
these five ``New England deemed counties,'' three (York County, 
Sagadahoc County, and Newport County) are also included in metropolitan 
statistical areas defined by OMB and are considered urban under both 
the current IPPS and LTCH PPS labor market area definitions in Sec.  
412.64(b)(1)(ii)(A) (they would also be urban under the proposed 
conforming changes to Sec.  412.503). The remaining two, Litchfield 
County and Merrimack County, are geographically located in areas that 
are considered rural under the current IPPS (and LTCH PPS) labor market 
area definitions (however, they have been previously deemed urban under 
the IPPS in certain circumstances as discussed below).
    In the FY 2008 IPPS final rule with comment period (72 FR 47337 
through 47338), Sec.  412.64(b)(1)(ii)(B) was revised such that the two 
``New England deemed counties'' that are still considered rural by OMB 
(Litchfield county, CT and Merrimack county, NH) are no longer 
considered urban effective for discharges occurring on or after October 
1, 2007, and therefore, are considered rural in accordance with Sec.  
412.64(b)(1)(ii)(C). However, for purposes of payment under the IPPS, 
acute-care hospitals located within those areas are treated as being 
reclassified to their deemed urban area effective for discharges 
occurring on or after October 1, 2007 (see 72 FR 47337 through 47338). 
(We note that the LTCH PPS does not provide for such geographic 
reclassification (67 FR 56019 through 56020)). Also in the FY 2008 IPPS 
final rule with comment period (72 FR 47338), we explained that we have 
limited this policy change for the ``New England deemed counties'' only 
to IPPS hospitals, and any change to non-IPPS provider wage indices 
would be addressed in the respective payment system rules. Accordingly, 
as stated above, we are taking this opportunity to clarify the 
treatment of ``New England

[[Page 5364]]

deemed counties'' under the LTCH PPS in this proposed rule.
    As discussed above, under existing Sec.  412.525(c)(2), a LTCH's 
wage index is determined based on the location of the LTCH in an urban 
or rural area as defined in Sec.  412.64(b)(1)(ii)(A) through (C). 
Under existing Sec.  412.525(c)(2), an urban area under the LTCH PPS is 
currently defined at Sec.  412.64(b)(1)(ii)(A) and (B), and a rural 
area is defined as any area outside of an urban area in Sec.  
412.64(b)(1)(ii)(C).
    Historical changes to the labor market area/geographic 
classifications and annual updates to the wage index values under the 
LTCH PPS have been made effective July 1 each year. When we established 
the most recent LTCH PPS payment rate update, effective for LTCH 
discharges occurring on or after July 1, 2007 through June 30, 2008, we 
considered the ``New England deemed counties'' (including Litchfield 
county, CT and Merrimack county, NH) as urban for RY 2008 (in 
accordance with the definitions of urban and rural stated in the RY 
2008 LTCH PPS final rule (72 FR 26891) and as evidenced by the 
inclusion of Litchfield county as one of the constituent counties of 
urban CBSA 25540 (Hartford-West Hartford-East Hartford, CT), and the 
inclusion of Merrimack county as one of the constituent counties of 
urban CBSA 31700 (Manchester-Nashua, NH)). (See 72 FR 27004 and 27008, 
respectively).
    As noted above, existing Sec.  412.525(c)(2) indicates that the 
terms ``rural'' and ``urban'' as areas are defined according to the 
definitions of those terms in Sec.  412.64(b)(1)(ii)(A) through (C). As 
Litchfield county, CT and Merrimack county, NH would be considered 
rural areas in accordance with our regulations at (Sec.  412.525(c)(2), 
these two counties will be ``rural'' under the LTCH PPS effective with 
the next update of the LTCH PPS payment rates, which will be July 1, 
2008 (under the LTCH PPS effective for discharges on or after July 1, 
2008, Litchfield County, CT and Merrimack County, NH are not urban 
under Sec.  412.64(b)(1)(ii)(A-B) and therefore are rural under Sec.  
412.64(b)(1)(ii)(c)). (We note that Litchfield and Merrimack counties 
will also be rural under our proposed Sec.  412.503, discussed in 
greater detail below, that would incorporate the existing definitions 
of ``urban'' and ``rural'' areas.) Therefore, Litchfield county, CT and 
Merrimack county, NH will be considered ``rural'' effective for LTCH 
PPS discharges occurring on or after July 1, 2008, and will no longer 
be considered as being part of urban CBSA 25540 (Hartford-West 
Hartford-East Hartford, CT) and urban CBSA 31700 (Manchester-Nashua, 
NH), respectively. We note that currently we are not aware of any LTCHs 
located in either Litchfield county, CT or Merrimack county, NH. We 
also note that this policy is consistent with our policy of not taking 
into account IPPS geographic reclassifications in determining payments 
under the LTCH PPS. In addition, as discussed above, in this section, 
effective for discharges on or after July 1, 2008, Sec.  
412.64(b)(1)(ii)(B) is no longer applicable under the LTCH PPS.
(4) Proposed Codification of the Definitions of Urban and Rural Under 
42 CFR Part 412 Subpart O
    Under the current regulations at Sec.  412.525(c), the labor-
related portion of the LTCH PPS Federal rate is adjusted to account for 
geographical differences in the area wage levels using an appropriate 
wage index to reflect the relative level of hospital wages and wage-
related costs in the geographic area (that is, urban or rural area) of 
the hospital compared to the national average level of hospital wages 
and wage-related costs annually. Currently, the application of the wage 
index under existing Sec.  412.525(c)(2) is made on the basis of the 
location of the facility in an urban or rural area as defined in Sec.  
412.64(b)(1)(ii)(A) through (C) (in 42 CFR Part 412 subpart D).
    In light of regulatory construct discussed above where Sec.  
412.525(c) indicated that the terms ``rural area'' and ``urban area'' 
as defined according to the definitions of those terms'' under the IPPS 
in 42 CFR Part 412 subpart D, we believe it may be administratively 
simpler to have the LTCH PPS urban and rural labor market area 
definitions self-contained in (Sec.  412.503) 42 CFR Part 412 subpart O 
rather than cross-referring to the definitions of urban and rural in 
the IPPS regulations in 42 CFR Part 412, Subpart D. This approach is 
similar to the change we made in Sec.  412.525(a) for high cost 
outliers and Sec.  412.529 for short-stay outliers in the FY 2007 IPPS 
final rule when we embedded within Subpart O the regulatory provisions 
concerning the determination of cost-to-charge ratios (CCRs) and the 
reconciliation of outlier payments (71 FR 48115 through 48122). Under 
the broad authority of Sec.  123 of the BBRA as amended by Sec.  307(b) 
of BIPA we are proposing to codify in Sec.  412.503 the definitions for 
``urban area'' and ``rural area.'' The proposed definitions for ``urban 
area'' and ``rural area'' in Sec.  412.503 would incorporate the 
provisions of Sec.  412.62(f)(1)(ii) and (f)(1)(iii) as well as Sec.  
412.64(b)(1)(ii)(A) through (C). Furthermore, since, as explained above 
in section IV.F.1.b.3., the definition of ``urban area'' at Sec.  
412.64(b)(1)(ii)(B) is no longer applicable under the LTCH PPS 
effective for discharges occurring on or after July 1, 2008, and 
therefore, the only remaining definition of ``urban area'' will be that 
of a Metropolitan Statistical Area (MSA) as defined by the Executive 
Office of Management and Budget. (See 72 FR 47337 through 47338). Thus, 
we omit the language of Sec.  412.64(b)(1)(ii)(B) from the proposed 
definition of ``urban area'' that would be applicable to discharges 
occurring on or after July 1, 2008 in proposed 412.503. We, however, 
included the language from Sec.  412.64(b)(1)(ii)(A) in the proposed 
definition of ``urban area'' that would be applicable to discharges 
occurring on or after July 1, 2008 in proposed 412.503. For the reason 
just described, we note that the proposed definitions of ``urban'' and 
``rural'' that would be effective for discharges occurring on or after 
July 1, 2008 (in subparagraph (3) in the both the proposed definition 
of ``rural area'' and the proposed definition of ``urban area'') vary 
slightly from the wording in the current regulations at Sec.  
412.64(b)(1)(ii)(A) through (C); however, substantively the definitions 
are the same. We believe that the slight difference in the wording of 
412.503 more precisely conveys the treatment of New England deemed 
counties under the LTCH PPS, as discussed above. As a conforming 
change, we are also proposing to replace the cross-references to Sec.  
412.62(f)(1)(iii) and Sec.  412.64(b)(1)(ii)(A) through (C) in Sec.  
412.525(c) with references to the proposed definitions of ``urban 
area'' and ``rural area'' at Sec.  412.503. Accordingly, we are 
proposing to revise Sec.  412.525(c) to specify that the application of 
the LTCH PPS wage index would be made on the basis of the location of 
the LTCH in an urban or rural area as defined in proposed Sec.  
412.503. As discussed in section VI.G.3. of this proposed rule, we are 
also proposing to make conforming changes to the regulations governing 
short-stay outlier payments (at Sec.  412.529) and the special payment 
provisions for co-located LTCHs (at Sec.  412.534) and free-standing 
LTCHs (at Sec.  412.536), which refer to the definition of urban and 
rural under the LTCH PPS.
c. Proposed Labor-Related Share
    In the August 30, 2002 LTCH PPS final rule (67 FR 56016), we 
established a labor-related share of 72.885 percent based on the 
relative importance of the labor-related share of operating costs 
(wages and salaries, employee benefits,

[[Page 5365]]

professional fees, postal services, and all other labor-intensive 
services) and capital costs of the excluded hospital with capital 
market basket based on FY 1992 data. We did not revise the labor-
related share in RYs 2004 through 2006 while we conducted further 
analysis to determine the most appropriate methodology and data for 
determining the labor-related share under the LTCH PPS (70 FR 24182). 
After our research into the labor-related share methodology was 
complete, we revised the labor-related share under the LTCH PPS in the 
RY 2007 final rule (71 FR 27829). Specifically, beginning in RY 2007, 
we established a labor-related share based on the relative importance 
of the labor-related share of operating costs (wages and salaries, 
employee benefits, professional fees, postal services, and all other 
labor-intensive services) and capital costs of the RPL market basket 
based on FY 2002 data, as it is the best available data that reflect 
the cost structure of LTCHs.
    Consistent with our historical practice, the labor-related share 
currently used under the LTCH PPS is determined by identifying the 
national average proportion of operating costs and capital costs that 
are related to, influenced by, or vary with the local labor market. 
Accordingly, in the RY 2008 LTCH PPS final rule (72 FR 26892), we 
updated the LTCH PPS labor-related share to 75.788 percent based on the 
relative importance of the labor-related share of operating costs 
(wages and salaries, employee benefits, professional fees, and all 
other labor-intensive services) and capital costs of the RPL market 
basket based on FY 2002 data from the first quarter of 2007.
    As discussed in section IV.C.2. of this preamble, we now have data 
from the 4th quarter of 2007 (with history through the 3rd quarter of 
2007) available for determining the labor-related share of the FY 2002-
based RPL market basket. Based on this more recent data, in this 
proposed rule, under the broad authority conferred upon the Secretary 
by section 123 of the BBRA as amended by section 307(b) of the BIPA, 
consistent with our historical practice of determining the labor-
related share by identifying the national average proportion of 
operating costs and capital costs that are related to, influenced by, 
or varies with the local labor market, we are proposing to revise the 
LTCH PPS labor-related share from 75.788 percent to 75.920 percent 
based on the relative importance of the labor-related share of 
operating costs (wages and salaries, employee benefits, professional 
fees, and all other labor-intensive services) and capital costs of the 
FY 2002-based RPL market basket from the fourth quarter of 2007, as 
shown in Table 1. The proposed labor-related share is the sum of the 
relative importance of wages and salaries, fringe benefits, 
professional fees, labor-intensive services, and a portion of the 
capital share from an appropriate market basket.
    In this proposed rule, for RY 2009, we are proposing to use the FY 
2002-based RPL market basket costs based on data from the fourth 
quarter of 2007 to determine the labor-related share for the LTCH PPS 
effective for discharges occurring on or after July 1, 2008 and before 
September 30, 2009, as this is the most recent available data. The 
proposed labor-related share for RY 2009 LTCH PPS would continue to be 
the sum of the relative importance of each labor-related cost category, 
and would reflect the different rates of price change for these cost 
categories between the base year (FY 2002) and the (15-month) 2009 LTCH 
PPS rate year. (As discussed in greater detail above in section IV.B. 
of this proposed rule, we are proposing to move the LTCH PPS annual 
payment rate year beginning July 1st to a rate year beginning October 
1st and have a 15-month rate year for 2009 (that is, July 1, 2008 
through September 30, 2009). Accordingly, we are proposing to use the 
15-month RY 2009 RPL market basket, discussed above, to determine the 
proposed labor-related share for RY 2009 in this proposed rule. 
Consistent with our historical practice of using the best data 
available, if more recent data are available to determine the labor-
related share of the RPL market basket (used under the LTCH PPS), we 
propose to use it for determining the labor-related share for the 2009 
LTCH PPS rate year in the final rule.
    Based on the most recent available data, we are proposing that the 
sum of the relative importance for the 2009 LTCH PPS rate year for 
operating costs (wages and salaries, employee benefits, professional 
fees, and labor-intensive services) would be 71.965, as shown in Table 
1. The portion of capital that is influenced by the local labor market 
is still estimated to be 46 percent, which is the same percentage used 
when we established the current labor-related share in the RY 2008 LTCH 
PPS final rule. Since, based on the most recent available data, the 
relative importance for capital would be 8.597 percent of the FY 2002-
based RPL market basket for the 2009 LTCH PPS rate year, we are 
proposing to multiply the estimated portion of capital influenced by 
the local labor market (46 percent) by the relative importance for 
capital (8.597 percent) to determine the proposed labor-related share 
of capital for the 2009 LTCH PPS rate year. The result would be 3.955 
percent (0.46 x 8.597 percent), which we would add to the proposed 
71.965 percent for the operating cost amount to determine the proposed 
total labor-related share for the 2009 LTCH PPS rate year. Thus, based 
on the latest available data, we are proposing to use a labor-related 
share of 75.920 percent (71.965 percent + 3.955 percent) under the LTCH 
PPS for the 2009 LTCH PPS rate year. As noted above in this section, 
this proposed labor-related share is determined using the same 
methodology as employed in calculating the current LTCH labor-related 
share (72 FR 26892) and the labor-related shares used under the IRF PPS 
and IPF PPS, which also use the RPL market basket.
    Table 1 shows the 2008 LTCH PPS rate year relative importance 
labor-related share of the FY 2002-based RPL market basket (established 
in the RY 2008 LTCH PPS final rule) and the proposed 2009 LTCH PPS rate 
year relative importance labor-related share of the FY 2002-based RPL 
market basket.

d. Proposed Wage Index Data
    Historically, under the LTCH PPS, we have established LTCH PPS wage 
index values calculated from acute care IPPS hospital wage data without 
taking into account geographic reclassification under sections 
1886(d)(8) and (d)(10) of the Act. As we discussed in the August 30, 
2002 LTCH PPS final rule (67 FR 56019), since hospitals that are 
excluded from the IPPS are not required to provide wage-related 
information on the Medicare cost report. Therefore, we would need to 
establish instructions for the collection of this LTCH data as well as 
develop some type of application and determination process before a 
geographic reclassification adjustment under the LTCH PPS could be 
implemented. Thus, the wage adjustment established under the LTCH PPS 
is based on a LTCH's actual location without regard to the urban or 
rural designation of any related or affiliated provider. Acute care 
hospital inpatient wage index data are also used to establish the wage 
index adjustment used in other Medicare PPSs, such as the IRF PPS, IPF 
PPS, HHA PPS, and SNF PPS.
    In the RY 2008 LTCH PPS final rule (72 FR 26893), we established 
LTCH PPS wage index values for the RY 2008 calculated from the same 
data (collected from cost reports submitted by hospitals for cost 
reporting periods beginning during FY 2003) used to compute the FY 2007 
acute care hospital inpatient wage index data without taking into 
account geographic reclassification under sections 1886(d)(8) and 
(d)(10) of the Act because that was the best available data at that 
time. The LTCH PPS wage index values applicable for discharges 
occurring on or after July 1, 2007 through June 30, 2008 are shown in 
Table 1 (for urban areas) and Table 2 (for rural areas) in the Addendum 
to the RY 2008 LTCH PPS final rule (72 FR 26996 through 27019).
    In this proposed rule, under the broad authority conferred upon the 
Secretary by section 123 of the BBRA as amended by section 307(b) of 
BIPA to determine appropriate adjustments under the LTCH PPS, we are 
proposing that, for the RY 2009, the same data (collected from cost 
reports submitted by hospitals for cost reporting periods beginning 
during FY 2004) used to compute the FY 2008 acute care hospital 
inpatient wage index data without taking into account geographic 
reclassification under sections 1886(d)(8) and (d)(10) of the Act would 
be used to determine the applicable wage index values under the LTCH 
PPS because these data (FY 2004) are the most recent complete data. 
(For information on the data used to compute the FY 2008 IPPS wage 
index refer to the FY 2008 IPPS final rule with comment period (72 FR 
47308 through 47309, 47315)). We are proposing to continue to use IPPS 
wage data as a proxy to determine the proposed LTCH wage index values 
for RY 2009 because both LTCHs and acute-care hospitals are required to 
meet the same certification criteria set forth in section 1861(e) of 
the Act to participate as a hospital in the Medicare program and they 
both compete in the same labor markets, and therefore, experience 
similar wage-related costs. We note that the IPPS wage data used to 
determine the proposed RY 2009 LTCH wage index values reflects our 
policy that was adopted under the IPPS beginning in FY 2008 that 
apportions the wage data for multicampus hospitals' located in 
different labor market areas (CBSAs) to each CBSA where the campuses 
are located (see the FY 2008 IPPS final rule with comment period (72 FR 
47317 through 47320)). For the proposed RY 2009 LTCH PPS wage index, 
which is computed from IPPS wage data submitted by hospitals for cost 
reporting periods beginning in FY 2004 (just like the FY 2008 IPPS wage 
index), we allocated salaries and hours to the campuses of two 
multicampus hospitals with campuses that are located in different labor 
areas, one in Massachusetts and another in Illinois. Thus, the proposed 
RY 2009 LTCH PPS wage index values for the following CBSAs are affected 
by this policy: Boston-Quincy, MA (CBSA 14484), Providence-New Bedford-
Falls River, RI-MA (CBSA 39300), Chicago-Naperville-Joliet, IL (CBSA 
16974) and Lake County-Kenosha County, IL-WI (CBSA 29404) (refer to 
Table 1 in the Addendum of this proposed rule). Furthermore, the 
proposed RY 2009 LTCH PPS wage index values presented in this proposed 
rule were computed consistent with the urban and rural geographic 
classifications (labor market areas) discussed above in section 
IV.F.1.b. of this proposed rule and consistent with pre-reclassified 
IPPS wage index policy (that is, our historical policy of not taking 
into account IPPS geographic reclassifications in determining payments 
under the LTCH PPS). Specifically, we note that the wage data of the 
IPPS hospitals located in Litchfield county, CT, and Merrimack county, 
NH, were included in the calculation of the proposed RY 2009 LTCH PPS 
statewide rural wage index values for Connecticut and New Hampshire, 
respectively (rather than urban CBSA 25540 (Hartford-West Hartford-East 
Hartford, CT) and urban CBSA 31700 (Manchester-Nashua, NH), 
respectively). In addition, the proposed RY 2009 wage index reflects 
our proposals (discussed in greater detail below) to establish wage 
index values in urban and rural areas in which there are no IPPS wage 
data from which to compute a wage index value under our methodology 
described above. As noted above, the IPPS wage data we are proposing to 
use are the same FY 2004 acute care hospital inpatient wage data that 
were used to compute the FY 2008 wage index currently used under the 
IPPS.
    In this proposed rule, under the broad authority conferred upon the 
Secretary by section 123 of the BBRA as amended by section 307(b) of 
BIPA to determine appropriate adjustments under the LTCH PPS, we are 
also proposing to establish a policy for determining LTCH

[[Page 5367]]

PPS wage index values for labor market areas in which there is no IPPS 
hospital wage data from which to compute a wage index value under our 
methodology described above. Currently, there are no LTCHs located in 
labor areas where there is no IPPS hospital wage data (or IPPS 
hospitals). However, we believe it is appropriate to establish a 
methodology for determining LTCH PPS wage index values for these areas 
in the event that in the future a LTCH should open in one of those 
areas. Thus, any LTCH that would open in area in which there is no IPPS 
wage data for which to compute a wage index based on our established 
methodology would have a wage index value assigned to them for 
determining their LTCH PPS payments. Under this proposal, each year we 
would determine a wage index value for any area in which there is no 
IPPS wage data based on the proposed methodologies described below. As 
IPPS hospitals may open or close at any time, the number of areas 
without any IPPS wage data may change from year to year, and even when 
an IPPS hospital does open in area where there are currently no IPPS 
hospitals, because there is a lag-time between the time a hospital 
opens or becomes an IPPS provider and when the hospital's cost report 
wage data are available to include in calculating the area wage index 
(see 72 FR 47323), we believe it is appropriate to establish a 
methodology for determining LTCH PPS wage index values for these areas, 
if necessary. Our proposed policies for determining LTCH PPS wage index 
values for areas with no IPPS hospital wage data are consistent with 
the policies that have been established under other Medicare post-acute 
care PPSs, such as SNF and HHA, as well as the IPPS.
    The first situation for which we are proposing to establish a 
policy for determining a LTCH PPS wage index value is for urban CBSAs 
with no IPPS wage data. As discussed above, as IPPS wage data is 
dynamic, it is possible that urban areas without IPPS wage data will 
vary in the future. Consistent with the policy established under other 
PPSs, such as the HHA (70 FR 40795 and 71 FR 65892 through 65893), we 
are proposing to use an average of all of the urban areas within the 
State to serve as a reasonable proxy for determining the LTCH PPS wage 
index for an urban area without specific IPPS hospital wage index data. 
We believe that an average of all of the urban areas within the State 
would be a reasonable proxy for determining the LTCH PPS wage index for 
an urban area in the State with no wage data because it is based on 
pre-reclassified IPPS wage data, it is easy to evaluate, and it uses 
the most geographically similar relative wage-related costs data 
available. (Our rationale for using pre-reclassified IPPS wage data is 
discussed above in the beginning of this section.) Based on the FY 2004 
IPPS wage data that we are proposing to use to determine the proposed 
RY 2009 LTCH PPS wage index (discussed above), there is no IPPS wage 
data for the urban area of Hinesville-Fort Stewart, GA (CBSA 25980). 
Consistent with our proposal for determining a LTCH PPS wage index 
value for urban areas with no IPPS wage data, in this proposed rule, we 
calculated the proposed wage index value for RY 2009 for CBSA 25980 as 
the average of the wage index values for all of the other urban areas 
within the State of Georgia (that is, CBSAs 10500, 12020, 12060, 12260, 
15260, 16860, 17980, 19140, 23580, 31420, 40660, 42340, 46660 and 
47580) (refer to Table 1 of the Addendum of this proposed rule). (As 
noted above, there are currently no LTCHs located in CBSA 25980). We 
believe that this policy could be readily applied to other urban CBSAs 
(besides CBSA 25980) that lack IPPS wage data (possibly due to acute-
care hospitals converting to a different provider type that does not 
submit the appropriate wage data). However, if the proposed policy is 
adopted, we may re-examine the application of this proposed policy 
should a similar situation arise in the future.
    The other situation for which we are proposing to establish a 
policy for determining a LTCH PPS wage index value is for rural areas 
with no IPPS wage data. As discussed above, as IPPS wage data is 
dynamic, it is possible that rural areas without IPPS wage data will 
vary in the future. Consistent with the policy established under other 
PPSs, such as the HHA (71 FR 65905 through 65906) and the IPPS (72 FR 
47323 through 47324), we are proposing to use the unweighted average of 
the wage indices from all of the CBSAs that are contiguous to the rural 
counties of the State to serve as a reasonable proxy in determining the 
LTCH PPS wage index for a rural area without specific IPPS hospital 
wage index data. For this purpose, we would define ``contiguous'' as 
sharing a border. We are not able to apply a similar averaging in rural 
areas with no wage data as we proposed above for urban areas with no 
wage data because there is no rural hospital data available for 
averaging on a state-wide basis. We believe that using an unweighted 
average of the wage indices from all of the CBSAs that are contiguous 
to the rural counties of the State would be a reasonable proxy for 
determining the wage index for rural areas in a State with no wage data 
because it is based on pre-reclassified IPPS wage data, it is easy to 
evaluate, and it uses the most geographically similar relative wage-
related costs data available. (Our rationale for using pre-reclassified 
IPPS wage data is discussed above in the beginning of this section.)
    Based on the FY 2004 IPPS data that we are proposing to use to 
determine the proposed RY 2009 LTCH PPS wage index (discussed above), 
rural Massachusetts (CBSA code 11) does not have any IPPS wage data. 
Consistent with our proposal for determining a LTCH PPS wage index 
value for rural areas with no IPPS hospital wage data, in this proposed 
rule, we determined the proposed wage index value for RY 2009 rural 
Massachusetts by computing the unweighted average of the wage indices 
from all of the CBSAs that are contiguous to the rural counties in that 
State. Specifically, in the case of Massachusetts, the entire rural 
area consists of Dukes and Nantucket counties. We determined that the 
borders of Dukes and Nantucket counties are ``contiguous'' with 
Barnstable County, MA, and Bristol County, MA. Therefore, the proposed 
RY 2009 LTCH PPS wage index value for rural Massachusetts would be 
computed as the unweighted average of the proposed RY 2009 wage indexes 
for Barnstable county and Bristol county (refer to Tables 1 and 2 of 
the Addendum of this proposed rule). (As noted above, there are 
currently no LTCHs located in rural Massachusetts.) We believe that 
this proposed policy could be readily applied to other rural areas 
(besides Massachusetts) that lack IPPS wage data (possibly due to 
acute-care hospitals converting to a different provider type that does 
not submit the appropriate wage data). However, if the proposed policy 
is adopted, we may re-examine the application of this proposed policy 
should a similar situation arise in the future.
    The proposed RY 2009 LTCH wage index values that would be 
applicable for LTCH discharges occurring on or after July 1, 2008 
through September 30, 2009, are presented in Table 1 (for urban areas) 
and Table 2 (for rural areas) in the Addendum of this proposed rule. As 
discussed in greater detail above in section IV.B. of this preamble, we 
are proposing to move the LTCH PPS annual payment rate update cycle 
from July 1 to October 1 and to have a 15-month rate year for 2009 
(that is, July 1, 2008 through September 30, 2009). Therefore, we note 
that if our proposal

[[Page 5368]]

to move the LTCH PPS annual payment rate update cycle is finalized, the 
next proposed update to the LTCH wage index values would be effective 
for discharges occurring on or after October 1, 2009 (FY 2010). In 
addition, as noted above, the wage index adjustment under the LTCH PPS 
was completely phased in beginning with cost reporting periods 
beginning in FY 2007 (that is, for cost reporting periods beginning on 
or after October 1, 2006). Therefore, for LTCH PPS discharges occurring 
during RY 2009, the labor related portion of the standard Federal rate 
will be adjusted by the applicable full (five fifths) proposed RY 2009 
LTCH PPS wage index value. (As noted above, the proposed RY 2009 LTCH 
PPS wage index values are shown in Tables 1 and 2 of the Addendum to 
this proposed rule).
2. Proposed Adjustment for Cost-of-Living in Alaska and Hawaii
    In the August 30, 2002 final rule (67 FR 56022), we established, 
under Sec.  412.525(b), a COLA for LTCHs located in Alaska and Hawaii 
to account for the higher costs incurred in those States. In the RY 
2008 LTCH PPS final rule (72 FR 26894), for RY 2008, we established a 
COLA to payments for LTCHs located in Alaska and Hawaii by multiplying 
the standard Federal payment rate by the appropriate factor listed in 
Table 3 of that same final rule.
    Similarly, in this proposed rule, under the broad authority 
conferred upon the Secretary by section 123 of the BBRA as amended by 
section 307(b) of BIPA to determine appropriate adjustments under the 
LTCH PPS, for RY 2009 we are proposing a COLA to payments to LTCHs 
located in Alaska and Hawaii by multiplying the proposed standard 
Federal payment rate by the proposed factors listed below in Table 2 
because these are currently the most recent available data. These 
proposed factors are obtained from the U.S. Office of Personnel 
Management (OPM) and are currently also used under the IPPS (72 FR 
47422). In addition, we propose that if OPM releases revised COLA 
factors before March 1, 2008, we would use them for the development of 
LTCH PPS payments for RY 2009 and publish those revised COLA factors in 
the final rule.

3. Proposed Adjustment for High-Cost Outliers (HCOs)
a. Background
    Under the broad authority conferred upon the Secretary by section 
123 of the BBRA as amended by section 307(b) of BIPA, in the 
regulations at Sec.  412.525(a), we established an adjustment for 
additional payments for outlier cases that have extraordinarily high 
costs relative to the costs of most discharges. Providing additional 
payments for outliers strongly improves the accuracy of the LTCH PPS in 
determining resource costs at the patient and hospital level. These 
additional payments reduce the financial losses that would otherwise be 
incurred when treating patients who require more costly care and, 
therefore, reduce the incentives to underserve these patients. We set 
the outlier threshold before the beginning of the applicable rate year 
so that total estimated outlier payments are projected to equal 8 
percent of total estimated payments under the LTCH PPS. Outlier 
payments under the LTCH PPS are determined consistent with the 
instructions issued for the IPPS outlier policy.
    Under Sec.  412.525(a) (in conjunction with the revised definition 
of ``LTC-DRG'' at Sec.  412.503), we make outlier payments for any 
discharges if the estimated cost of a case exceeds the adjusted LTCH 
PPS payment for the MS-LTC-DRG plus a fixed-loss amount. Specifically, 
in accordance with Sec.  412.525(a)(3) (in conjunction with the revised 
definition of ``LTC-DRG'' at Sec.  412.503), we pay outlier cases 80 
percent of the difference between the estimated cost of the patient 
case and the outlier threshold (the sum of the adjusted Federal 
prospective payment for the MS-LTC-DRG and the fixed-loss amount). The 
fixed-loss amount is the amount used to limit the loss that a hospital 
will incur under the outlier policy for a case with unusually high 
costs. This results in Medicare and the LTCH sharing financial risk in 
the treatment of extraordinarily costly cases. Under the LTCH PPS HCO 
policy, the LTCH's loss is limited to the fixed-loss amount and a fixed 
percentage (currently 80 percent) of costs above the outlier threshold 
(LTCH DRG payment plus the fixed loss amount). The fixed percentage of 
costs is called the marginal cost factor. We calculate the estimated 
cost of a case by multiplying the Medicare allowable covered charge by 
the overall hospital cost-to-charge ratio (CCR).
    Under the LTCH PPS, we determine a fixed-loss amount, that is, the 
maximum loss that a LTCH can incur under the LTCH PPS for a case with 
unusually high costs before the LTCH will receive any additional 
payments. We calculate the fixed-loss amount by estimating aggregate 
payments with and without an outlier policy. The fixed-loss amount will 
result in estimated total outlier payments being projected to be equal 
to 8 percent of projected total LTCH PPS payments. Currently, MedPAR 
claims data and CCRs based on data from the most recent provider 
specific file (PSF) (or to the applicable Statewide average CCR if a 
LTCH's CCR data are faulty or unavailable) are used to establish a 
fixed-loss threshold amount under the LTCH PPS.
b. Cost-to-Charge Ratios (CCRs)
    The following is a discussion of cost-to-charge ratios (CCRs) used 
in determining payments for high cost and short-stay outlier cases 
under the LTCH PPS, at Sec.  412.525(a) and Sec.  412.529, 
respectively. Although this section is specific to high cost outlier 
cases, because CCRs and the policies and methodologies pertaining to 
them are used in determining payments for both high cost and short-stay 
outlier cases, (as explained below), we are discussing the 
determination of CCRs under the LTCH PPS for both of these type of 
cases simultaneously. In section IV.G. of this proposed rule, which 
discusses short-stay outlier (SSO) cases, we refer the reader to this 
section of the preamble for a complete discussion on the determination 
of CCRs.
    In determining both high-cost outlier payments (at Sec.  
412.525(a)) and short-stay outlier payments (at Sec.  412.529), we 
calculate the estimated cost of the case by multiplying the LTCH's 
overall CCR by the Medicare allowable charges for the case. In general, 
we use the LTCH's overall CCR, which is computed based on either the 
most recently settled cost report or the most recent tentatively 
settled cost report, whichever is from

[[Page 5369]]

the latest cost reporting period, in accordance with Sec.  
412.525(a)(4)(iv)(B) and Sec.  412.529(c)(4)(iv)(B) for high cost 
outliers and SSOs, respectively. (We note that in some instances we use 
an alternative CCR, such as the statewide average CCR in accordance 
with the regulations at Sec.  412.525(a)(4)(iv)(C) and Sec.  
412.529(c)(4)(iv)(C), or a CCR that is specified by CMS or that is 
requested by the hospital under the provisions of the regulations at 
Sec.  412.525(a)(4)(iv)(A) and Sec.  412.529(c)(4)(iv)(A).) Under the 
LTCH PPS, a single prospective payment per discharge is made for both 
inpatient operating and capital-related costs. Therefore, we compute a 
single ``overall'' or ``total'' LTCH-specific CCR based on the sum of 
LTCH operating and capital costs (as described in Chapter 3, section 
150.24, of the Medicare Claims Processing Manual (CMS Pub. 100-4)) as 
compared to total charges. Specifically, a LTCH's CCR is calculated by 
dividing a LTCH's total Medicare costs (that is, the sum of its 
operating and capital inpatient routine and ancillary costs) by its 
total Medicare charges (that is, the sum of its operating and capital 
inpatient routine and ancillary charges).
    Generally, a LTCH is assigned the applicable statewide average CCR 
if, among other things, a LTCH's CCR is found to be in excess of the 
applicable maximum CCR threshold (that is, the LTCH CCR ceiling). This 
is because CCRs above this threshold are most likely due to faulty data 
reporting or entry, and, therefore, these CCRs should not be used to 
identify and make payments for outlier cases. Such data are clearly 
errors and should not be relied upon. Thus, under our established 
policy, generally, if a LTCH's calculated CCR is above the applicable 
ceiling, the applicable LTCH PPS statewide average CCR is assigned to 
the LTCH instead of the CCR computed from its most recent (settled or 
tentatively settled) cost report data.
    In the FY 2008 IPPS final rule with comment period, in accordance 
with Sec.  412.525(a)(4)(iv)(C)(2) for high-cost outliers and Sec.  
412.529(c)(4)(iv)(C)(2) for short-stay outliers, using our established 
methodology for determining the LTCH total CCR ceiling, based on IPPS 
total CCR data from the March 2007 update to the Provider-Specific File 
(PSF), we established a total CCR ceiling of 1.284 under the LTCH PPS 
effective October 1, 2007 through September 30, 2008. (For further 
detail on our methodology for annually determining the LTCH total CCR 
ceiling, we refer readers to the FY 2007 IPPS final rule (71 FR 48119 
through 48121) and the FY 2008 IPPS final rule with comment period (72 
FR 47403 through 47404).)
    Our general methodology established for determining the statewide 
average CCRs used under the LTCH PPS is similar to our established 
methodology for determining the LTCH total CCR ceiling (described 
above) since it is based on ``total'' IPPS CCR data. Under the LTCH PPS 
HCO policy at Sec.  412.525(a)(4)(iv)(C) and the short-stay outlier 
policy at Sec.  412.529(c)(4)(iv)(C), the FI may use a statewide 
average CCR, which is established annually by CMS, if it is unable to 
determine an accurate CCR for a LTCH in one of the following 
circumstances: (1) New LTCHs that have not yet submitted their first 
Medicare cost report (for this purpose, consistent with current policy, 
a new LTCH would be defined as an entity that has not accepted 
assignment of an existing hospital's provider agreement in accordance 
with Sec.  489.18); (2) LTCHs whose CCR is in excess of the LTCH CCR 
ceiling (as discussed above); and (3) other LTCHs for whom data with 
which to calculate a CCR are not available (for example, missing or 
faulty data). (Other sources of data that the FI may consider in 
determining a LTCH's CCR include data from a different cost reporting 
period for the LTCH, data from the cost reporting period preceding the 
period in which the hospital began to be paid as a LTCH (that is, the 
period of at least 6 months that it was paid as a short-term acute care 
hospital), or data from other comparable LTCHs, such as LTCHs in the 
same chain or in the same region.)
    In the FY 2008 IPPS final rule with comment period, in accordance 
with Sec.  412.525(a)(4)(iv)(C) for high-cost outliers and Sec.  
412.529(c)(4)(iv)(C) for short-stay outliers, using our established 
methodology for determining the LTCH statewide average CCRs, based on 
the most recent complete IPPS total CCR data from the March 2007 update 
of the PSF, the LTCH PPS statewide average total CCRs for urban and 
rural hospitals effective for discharges occurring on or after October 
1, 2007, and before October 1, 2008, are presented in Table 8C of the 
Addendum to that final rule with comment period (72 FR 48127). (For 
further detail on our methodology for annually determining the LTCH 
urban and rural statewide average CCRs, we refer readers to the FY 2007 
IPPS final rule (71 FR 48119 through 48121) and FY 2008 IPPS final rule 
with comment period (72 FR 47403 through 47404).)
    We note, under the LTCH PPS high cost outlier policy at Sec.  
412.525(a)(4)(iv)(D) and the LTCH PPS SSO policy at Sec.  
412.529(c)(4)(iv)(D), the payments for high cost outlier and SSO cases, 
respectively, are subject to reconciliation. Specifically, any 
reconciliation of outlier payments is based on the CCR calculated based 
on a ratio of costs to charges computed from the relevant cost report 
and charge data determined at the time the cost report coinciding with 
the discharge is settled. For additional information, refer to the RY 
2008 LTCH PPS final rule (72 FR 26899 through 26900).
c. Establishment of the Proposed Fixed-Loss Amount
    When we implemented the LTCH PPS, as discussed in the August 30, 
2002 LTCH PPS final rule (67 FR 56022 through 56026), under the broad 
authority of section 123 of the BBRA as amended by section 307(b) of 
BIPA, we established a fixed-loss amount so that total estimated 
outlier payments are projected to equal 8 percent of total estimated 
payments under the LTCH PPS. To determine the fixed-loss amount, we 
estimate outlier payments and total LTCH PPS payments for each case 
using claims data from the MedPAR files. Specifically, to determine the 
outlier payment for each case, we estimate the cost of the case by 
multiplying the Medicare covered charges from the claim by the LTCH's 
hospital specific CCR. Under Sec.  412.525(a)(3) (in conjunction with 
the revised definition of ``LTC-DRG'' at Sec.  412.503), if the 
estimated cost of the case exceeds the outlier threshold (the sum of 
the adjusted Federal prospective payment for the MS-LTC-DRG and the 
fixed-loss amount), we pay an outlier payment equal to 80 percent of 
the difference between the estimated cost of the case and the outlier 
threshold (the sum of the adjusted Federal prospective payment for the 
MS-LTC-DRG and the fixed-loss amount).
    In the RY 2008 LTCH PPS final rule (72 FR 26898), in calculating 
the fixed-loss amount that would result in estimated outlier payments 
projected to be equal to 8 percent of total estimated payments for the 
2008 LTCH PPS rate year, we used claims data from the December 2006 
update of the FY 2006 MedPAR files and CCRs from the December 2006 
update of the PSF, as that was the best available data at that time. We 
believe that CCRs from the PSF are the best available CCR data for 
determining estimated LTCH PPS payments for a given LTCH PPS rate year 
because they are the most recently available CCRs actually used to make 
LTCH PPS payments.
    As we also discussed in the RY 2008 LTCH PPS rate year final rule 
(72 FR 26898), we calculated a single fixed-loss

[[Page 5370]]

amount for the 2008 LTCH PPS rate year based on the version 24.0 of the 
GROUPER, which was the version in effect as of the beginning of the 
LTCH PPS rate year (that is, July 1, 2007 for the 2008 LTCH PPS rate 
year). In addition, we applied the outlier policy under Sec.  
412.525(a) in determining the fixed-loss amount for the 2008 LTCH PPS 
rate year; that is, we assigned the applicable Statewide average CCR 
only to LTCHs whose CCRs exceeded the ceiling (and not when they fell 
below the floor). Accordingly, we used the FY 2007 LTCH PPS total CCR 
ceiling of 1.321 (72 FR 26898). As noted in that same final rule, in 
determining the fixed-loss amount for the 2008 LTCH PPS rate year using 
the CCRs from the PSF, there were no LTCHs with missing CCRs or with 
CCRs in excess of the current ceiling and, therefore, there was no need 
for us to independently assign the applicable Statewide average CCR to 
any LTCHs in determining the fixed-loss amount for the 2008 LTCH PPS 
rate year (as this may have already been done by the FI in the PSF in 
accordance with the established policy).
    Accordingly, in 2008 LTCH PPS rate year final rule (72 FR 26898), 
as amended by the RY 2008 correction notice (72 FR 36613), we 
established a fixed-loss amount of $20,738 for the 2008 LTCH PPS rate 
year. Thus, we pay an outlier case 80 percent of the difference between 
the estimated cost of the case and the outlier threshold (the sum of 
the adjusted Federal LTCH PPS payment for the MS-LTC-DRG and the fixed-
loss amount of $20,738).
    In this proposed rule, for the 2009 LTCH PPS rate year, we used the 
March 2006 update of the FY 2006 MedPAR claims data to determine a 
proposed fixed-loss amount that would result in estimated outlier 
payments projected to be equal to 8 percent of total estimated 
payments, based on the policies described in this proposed rule, 
because these data are the most recent complete LTCH data available. 
Consistent with our historical practice of using the best data 
available, if more recent LTCH claims data become available, we propose 
to use it for determining the fixed-loss amount for the 2009 LTCH PPS 
rate year in the final rule. Furthermore, as noted previously, we 
determined the proposed fixed-loss amount based on the version of the 
GROUPER that would be in effect as of the beginning of the 2009 LTCH 
PPS rate year (July 1, 2008), that is, Version 25.0 of the GROUPER (as 
established in the FY 2008 IPPS final rule (72 FR 47278)).
    We also used CCRs from the July 2007 update of the PSF for 
determining the proposed fixed-loss amount for the 2009 LTCH PPS rate 
year as they are currently the most recent complete available data. 
Consistent with our historical practice of using the best data 
available, if more recent CCR data are available, we propose to use it 
for determining the fixed-loss amount for the 2009 LTCH PPS rate year 
in the final rule. Furthermore, in determining the proposed fixed-loss 
amount for the 2009 LTCH PPS rate year, we used the current FY 2008 
applicable LTCH ``total'' CCR ceiling of 1.284 and LTCH Statewide 
average ``total'' CCRs established in the FY 2008 IPPS final rule (72 
FR 47404 and 48126 through 48127) such that the current applicable 
Statewide average CCR would be assigned if, among other things, a 
LTCH's CCR exceeded the current ceiling (1.284). We note that in 
determining the proposed fixed-loss amount for the 2009 LTCH PPS rate 
year using the CCRs from the PSF, there was no need for us to 
independently assign the applicable Statewide average CCR to any LTCHs 
(as this may have already been done by the FI in the PSF in accordance 
with our established policy). (Currently, the applicable FY 2008 LTCH 
Statewide average CCRs can be found in Table 8C of the FY 2008 IPPS 
final rule (72 FR 48126 through 48127).)
    Accordingly, based on the data and policies described in this 
proposed rule, we are proposing a fixed-loss amount of $21,199 for the 
2009 LTCH PPS rate year. Thus, we would pay an outlier case 80 percent 
of the difference between the estimated cost of the case and the 
proposed outlier threshold (the sum of the adjusted proposed Federal 
LTCH payment for the MS-LTC-DRG and the proposed fixed-loss amount of 
$21,199). We note that the proposed fixed-loss amount for the 2009 LTCH 
PPS rate year is somewhat higher than the current fixed-loss amount of 
$20,738. In addition to being based on the most recent available LTCH 
data to estimate the cost of each LTCH case, this proposed change in 
the fixed-loss amount is primarily due to the projected increase in 
estimated aggregate LTCH PPS payments that is expected to result from 
the proposed 2.6 percent update to the Federal rate (discussed in 
greater detail in section IV.E. of this preamble), in conjunction with 
the proposed changes to the area wage adjustment (discussed in greater 
detail in section IV.F.1. of this preamble) and the changes to the MS-
LTC-DRG relative weights for FY 2008 (as discussed in the FY 2008 IPPS 
final rule (72 FR 47277 through 47299)). As discussed in greater detail 
in the impact analysis presented in section XII. of this proposed rule, 
we are projecting that the proposed changes would result in a 1.7 
percent increase in estimated payments per discharge in RY 2009 as 
compared to RY 2008, on average, for all LTCHs. Because of the 
estimated increase in aggregate LTCH PPS payments proposed for the 2009 
LTCH PPS rate year (as discussed above in this section), we believe 
that an increase in the proposed fixed-loss amount is appropriate and 
necessary to maintain the requirement that estimated outlier payments 
would be projected to be equal to 8 percent of estimated total LTCH PPS 
payments, as required under Sec.  412.525(a). As we discussed in the RY 
2008 final rule (72 FR 26897), maintaining the fixed-loss amount at the 
current level would result in HCO payments above the current regulatory 
requirement that estimated outlier payments would be projected to equal 
8 percent of estimated total LTCH PPS payments. Based on the regression 
analysis that was performed when we implemented the LTCH PPS (August 
30, 2002 final rule (67 FR 56022 through 56027)), we established the 
outlier target at 8 percent of estimated total LTCH PPS payments to 
allow us to achieve a balance between the ``conflicting considerations 
of the need to protect hospitals with costly cases, while maintaining 
incentives to improve overall efficiency'' (67 FR 56024). That 
regression analysis also showed that additional increments of outlier 
payments over 8 percent (that is, raising the outlier target to a 
larger percentage than 8 percent) would reduce financial risk, but by 
successively smaller amounts. Outlier payments are budget neutral, and 
therefore, outlier payments are funded by prospectively reducing the 
non-outlier PPS payment rates by projected total outlier payments. The 
higher the outlier target, the greater the (prospective) reduction to 
the base payment would need to be applied to the Federal rate to 
maintain BN.
    As we discussed in the RY 2008 LTCH PPS final rule (72 FR 26898 
through 26899), as an alternative to proposing to lower the fixed-loss 
amount for RY 2009, we examined adjusting the marginal cost factor 
(that is, the percentage that Medicare will pay of the estimated cost 
of a case that exceeds the sum of the adjusted Federal prospective 
payment for the MS-LTC-DRG and the fixed-loss amount for LTCH PPS 
outlier cases as specified in Sec.  412.525(a)(3) in conjunction with 
the revised definition of ``LTC-DRG'' at Sec.  412.503), which is 
currently equal to 80 percent, as a means of ensuring that estimated 
outlier payments would be

[[Page 5371]]

projected to equal 8 percent of estimated total LTCH PPS payments. When 
we initially established the 80 percent marginal cost factor in the 
August 30, 2002 final rule (67 FR 56022 through 56027), we explained 
that our analysis of payment-to-cost ratios for HCO cases showed that a 
marginal cost factor of 80 percent appropriately addresses outlier 
cases that are significantly more expensive than nonoutlier cases, 
while simultaneously maintaining the integrity of the LTCH PPS.
    In proposing increases to the fixed-loss amount for RY 2007 and RY 
2008 (71 FR 27834 and 72 FR 4799 through 4800 respectively), we also 
solicited comments on whether we should revisit the regression analysis 
discussed above in this section that was used to establish the existing 
8 percent outlier target and 80 percent marginal cost factor, using the 
most recent available data to evaluate whether the current outlier 
target of 8 percent or the 80 percent marginal cost factor should be 
adjusted, and therefore, could have resulted in less of an increase in 
the fixed-loss amount for RY 2007 and RY 2008, respectively. In 
response to this solicitation in the RY 2007 proposed rule (as 
summarized in the RY 2007 LTCH PPS final rule (71 FR 27834 through 
27835)), several commenters opposed any option that would allow us to 
revisit the regression analysis that was used to establish the existing 
80 percent marginal cost factor and existing outlier target of 8 
percent. The commenters stated their belief that the LTCH PPS is still 
in its early stages and further changes to the 80 percent marginal cost 
factor or 8 percent outlier target would result in instability to the 
system. The commenters cautioned against making any premature changes 
to the factors affecting HCO payments to LTCHs, particularly the 
marginal cost factor and outlier target established by regulation when 
the LTCH PPS was implemented. Also, the commenters agreed that keeping 
the marginal cost factor at 80 percent and the outlier pool at 8 
percent better identifies LTCH patients that are truly unusually costly 
cases, and that this policy appropriately addresses outlier cases that 
are significantly more expensive than non-outlier cases. Similarly, as 
summarized in the RY 2008 final rule (72 FR 26897), we received no 
comments in support of revisiting the regression analysis discussed 
above that was used to establish the existing 8 percent outlier target 
and 80 percent marginal cost factor, using the most recent available 
data to evaluate whether the current outlier target of 8 percent or the 
80 percent marginal cost factor should be adjusted in response to our 
solicitation on this issue.
    In response to these comments, we agreed with the commenters that, 
based on the regression analysis done for the implementation of the 
LTCH PPS (August 30, 2002; 68 FR 56022 through 56026), a marginal cost 
factor of 80 percent and a outlier target of 8 percent best identifies 
LTCH patients that are truly unusually costly cases, and that such a 
policy appropriately addresses LTCH HCO cases that are significantly 
more expensive than non-outlier cases, which is consistent with our 
intent of the LTCH HCO policy as stated when we implemented the LTCH 
PPS in the August 30, 2002 final rule (67 FR 56025). Therefore, as 
supported by many commenters, in both the RY 2007 final rule (71 FR 
27835) and the RY 2008 final rule (72 FR 26898), we did not revisit the 
regression analysis that was used to establish the existing 80 percent 
marginal cost factor and existing outlier target of 8 percent, and 
therefore, did not make any changes to the marginal cost factor or 
outlier target in either of those final rules.
    Although proposing to increase the fixed-loss amount from $20,738 
to $21,199 (based on the policies presented in this proposed rule) 
would increase the amount of the ``loss'' that a LTCH must incur under 
the LTCH PPS for a case with unusually high costs before the LTCH would 
receive any additional Medicare payments, as we discussed above and as 
we explained in greater detail in the RY 2006 LTCH PPS final rule (70 
FR 24195 through 24196), we continue to believe that the existing 8 
percent outlier target and 80 percent marginal cost factor continue to 
adequately maintain the LTCHs' share of the financial risk in treating 
the most costly patients and ensure the efficient delivery of services. 
Accordingly, we are not proposing to adjust the existing 8 percent 
outlier target or 80 percent marginal cost factor under the LTCH PPS 
HCO policy at this time. However, we continue to be interested in any 
comments that would support revisiting the analysis that was used to 
establish the existing 8 percent outlier target and the existing 80 
percent marginal cost factor, using the most recent available data to 
evaluate whether any changes to the current HCO policy should be made, 
and therefore, may result in a smaller increase (or even a decrease) in 
the fixed-loss amount for RY 2009.
    For the reasons described above, we believe the proposed fixed-loss 
amount of $21,199 would appropriately identify unusually costly LTCH 
cases while maintaining the integrity of the LTCH PPS. Thus, under the 
broad authority of section 123(a)(1) of the BBRA and section 307(b)(1) 
of BIPA, we are proposing a fixed-loss amount of $21,199 based on the 
best available LTCH data and the policies presented in this proposed 
rule because we believe a proposed increase in the fixed-loss amount is 
appropriate and necessary to maintain estimated outlier payments are 
projected to be equal to 8 percent of estimated total LTCH PPS 
payments, as required under Sec.  412.525(a).
d. Application of Outlier Policy to Short-Stay Outlier (SSO) Cases
    As we discussed in the August 30, 2002 final rule (67 FR 56026), 
under some rare circumstances, a LTCH discharge could qualify as a SSO 
case (as defined under Sec.  412.529 and discussed in section IV.G. of 
this preamble) and also as a HCO case. In this scenario, a patient 
could be hospitalized for less than five-sixths of the geometric ALOS 
for the specific MS-LTC-DRG, and yet incur extraordinarily high 
treatment costs. If the costs exceeded the high cost outlier threshold 
(that is, the SSO payment plus the fixed-loss amount), the discharge is 
eligible for payment as a HCO. Thus, for a SSO case in the 2009 LTCH 
PPS rate year, the HCO payment would be 80 percent of the difference 
between the estimated cost of the case and the proposed outlier 
threshold (the sum of the proposed fixed-loss amount of $21,199 and the 
amount paid under the SSO policy as specified in Sec.  412.529).
4. Other Payment Adjustments
    Section 123(a)(1) of the BBRA, as amended by section 307(b) of 
BIPA, granted the Secretary broad authority to determine appropriate 
adjustments under the LTCH PPS, including whether (and how) to provide 
for adjustments to reflect variations in the necessary costs of 
treatment among LTCHs. In developing the LTCH PPS payment methodology, 
we conducted extensive regression analyses of the relationship between 
LTCH costs (including both operating and capital-related costs per 
case) and several factors that may affect costs such as the percent of 
Medicaid patients treated, the percent of Supplemental Security Income 
(SSI) patients treated, the hospital's geographic location, and 
training residents in approved medical education programs (67 FR 
56014). The appropriateness of potential payment adjustments were 
evaluated based upon whether including each adjustment increased the 
accuracy of payments to LTCHs.

[[Page 5372]]

    In the August 30, 2002 LTCH PPS final rule, we detailed the 
extensive data analysis performed by our contractor, 3M Health 
Information Systems (3M) and our resulting decisions to implement a 
COLA for LTCHs in Alaska and Hawaii (Sec.  412.525(b)) and an 
adjustment to account for geographical differences in area wage levels 
(Sec.  412.525(c)). In addition, we discussed the extensive data 
analyses that led to the decision not to implement adjustments for 
geographic reclassification, rural location, the treatment of a 
disproportionate share of low-income patients (DSH), or indirect 
medical education (IME) costs. We also noted that we would continue to 
collect data and revisit these determinations as additional data became 
available. (For more detailed information, see 67 FR 56014 through 
56027.)
    When we implemented the LTCH PPS for FY 2003, we provided for a 5-
year transition period (Sec.  412.533), to allow LTCHs time to adjust 
to the new payment system (67 FR 56038). For cost reporting periods 
beginning on or after October 1, 2006, the final year of the 5-year 
transition, LTCHs are paid based on 100 percent of the Federal rate.
    We continued to collect and interpret new data as they became 
available to determine if these data support proposing any additional 
payment adjustments. In both the RY 2007 and the RY 2008 LTCH PPS final 
rules, we stated that we believed that it was appropriate to wait for 
the conclusion of the 5-year transition to 100 percent of the Federal 
rate under the LTCH PPS to maximize the availability of data that 
reflected LTCH behavior in response to the implementation of the LTCH 
PPS. The availability of this data would allow us to conduct a 
comprehensive reevaluation of payment adjustments under the LTCH PPS. 
(See the RY 2007 and RY 2008 LTCH PPS final rules (71 FR 27839) and (72 
FR 26900), respectively.)
    Therefore, similar to the data analyses conducted at the inception 
of the LTCH PPS for FY 2003, 3M evaluated LTCH data from the most 
recent cost report files in our HCRIS database (updated through June 
30, 2007) for providers' cost reports beginning during fiscal years 
2004 through 2006. We believe that in the 5 years since the start of 
the LTCH PPS, there has been sufficient new data generated to allow for 
a comprehensive reevaluation of the appropriateness of payment 
adjustments such as geographic reclassification, rural location, DSH, 
and IME under the LTCH PPS at this time.
    Our most recent data analysis which is based on the comprehensive 
data analysis by 3M (referenced above), indicates that proposing 
payment adjustments for geographic reclassification, rural location, 
DSH, or indirect medical education (IME) costs would not improve the 
accuracy of payments to LTCHs. (3M's ``Report on LTCH Payment 
Methodology Review and Results'' is posted on our Web site at: http://www.cms.hhs.gov/LongTermCareHospitalPPS/08_download.asp#TopOfPage.
    We believe that these analyses confirm our initial determinations 
as we developed the LTCH PPS regarding the applicability of PPS payment 
adjustments. Therefore, we are not proposing to adopt any additional 
payment adjustments such as geographic reclassification, rural 
location, DSH, or IME, as features of the LTCH PPS. Proposed policies 
for the RY 2009 wage index adjustment and the COLA are discussed in 
sections IV.D.1 and 2. of this proposed rule, respectively. 
Furthermore, now that the 5-year transition to the LTCH PPS is 
completed, we have collected data that reflects LTCH behavior in 
response to the implementation of the LTCH PPS. We believe that our 
above described analyses of LTCH PPS data do not support the adoption 
of any additional payment adjustments. We further believe that since 
3M's recent analyses confirm policy determinations that have been in 
place since the implementation of the LTCH PPS for FY 2003, that annual 
data analyses related to potential payment adjustments for geographic 
reclassification, rural location, DSH or IME will not be necessary 
barring significant transformations in the nature of the LTCH universe 
or substantial changes in Medicare payment outcomes that warrant 
additional evaluation.
5. Technical Correction to the Budget Neutrality Requirement at Sec.  
412.523(d)(2)
    Section 123(a)(1) of the Public Law 106-113 requires that the PPS 
developed for LTCHs be budget neutral for the initial year of 
implementation. Furthermore, under section 307(a)(2) of the Public Law 
106-554, the increases to the target amounts and the cap on the target 
amounts for LTCHs provided for by section 307(a)(1) of Public Law 106-
554 (as set forth in section 1886(b)(3)(J) of the Act), and the 
enhanced bonus payments for LTCHs provided for by section 122 of Public 
Law 106-113 (as set forth in section 1886(b)(2)(E) of the Act) were not 
to be taken into account in the development and implementation of the 
LTCH PPS. Therefore, when we implemented the LTCH PPS, in the August 
30, 2002 final rule (67 FR 56052), we established a budget neutrality 
requirement at Sec.  412.523(d)(2) for calculating the standard Federal 
rate for FY 2003 such that estimated aggregate LTCH PPS payments were 
estimated to be equal to estimated payments that would have been made 
to LTCHs under the reasonable cost-based payment methodology had the 
PPS for LTCHs not been implemented, and, to implement section 307(a)(2) 
of the Public Law 106-554, we excluded the effects of sections 
1886(b)(2) and (b)(3) of the Act.
    We are proposing a technical correction to existing Sec.  
412.523(d)(2) that would more precisely describe the provisions of 
sections 1886(b)(2) and (b)(3) of the Act that were not taken into 
account when determining the standard Federal rate under Sec.  
412.523(d). The current regulatory language at Sec.  412.523(d)(2) 
cites the general sections of the Act which contain the specific 
provisions set forth in Sec.  307(a)(2) of Public Law 106-554 that the 
Secretary is required to not take into account in developing the PPS. 
We believe that it is clearer and more precise to cite the specific 
subparagraphs the Secretary did not take into account rather than to 
cite the general sections of the Act of which such subparagraphs are a 
part. In order to mitigate any confusion that may be caused by existing 
regulations, we are proposing to make a technical correction at Sec.  
412.523(d)(2). Specifically, we are proposing to revise Sec.  
412.523(d)(2) to state that the effects of section 1886(b)(2)(E) of the 
Act (enhanced bonus payments for LTCHs, as described above) and section 
1886(b)(3)(J) of the Act (increases to the hospital-specific target 
amounts and the cap on the target amounts for LTCHs, as described 
above) were excluded in the development of the FY 2003 LTCH PPS 
standard Federal rate. This technical correction would make the 
regulatory language consistent with section 307(a)(2) of Public Law 
106-113 and consistent with the methodology we used to determine the 
LTCH PPS standard Federal rate under Sec.  412.523, and it is not a 
change in policy. (Accordingly, no adjustments to the LTCH PPS standard 
Federal rate computed under Sec.  412.523(d) have been proposed in 
conjunction with this proposed technical correction to Sec.  
412.523(d)(2).)

G. Proposed Conforming Changes

    Various regulations throughout 42 CFR Part 412 Subpart O indicate 
that the terms ``urban area'' and ``rural area'' are defined according 
to the definitions of ``urban area'' and ``rural area'' found in 42 CFR 
Part 412 Subpart D (the IPPS

[[Page 5373]]

regulations). Specifically, Sec. Sec.  412.525(c), 412.529(d)(4)(ii)(B) 
and (d)(4)(iii)(B), 412.534(d)(1), (f)(2)(ii), and (f)(3)(ii), and 
412.536(c)(1), (e)(2)(ii), and (e)(3)(ii) of Subpart O refer to the 
definitions of ``urban area'' and ``rural area'' in either Sec.  
412.62(f)(1)(ii) and (f)(1)(iii) or Sec.  412.64(b)(1)(ii)(A)-(C) in 42 
CFR Part 412 Subpart D. As stated elsewhere in the preamble, we believe 
that it is administratively simpler to define the terms ``urban area'' 
and ``rural area'' in Sec.  412.503 rather than cross-referencing the 
definitions of ``urban area'' and ``rural area'' in Sec.  
412.62(f)(1)(ii) and Sec.  412.62(f)(1)(iii) and Sec.  
412.64(b)(1)(ii)(A)-(C). Consequently, in section IV.F.1.b(4). of this 
regulation, we propose to add definitions for ``urban area'' and 
``rural area'' in Sec.  412.503 which would incorporate the provisions 
of Sec.  412.62(f)(1)(ii) and (f)(1)(iii) as well as Sec.  
412.64(b)(1)(ii)(A) through (C). Because we are proposing to define 
``urban area'' and ``rural area'' in Sec.  412.503, the citations to 
the definitions of ``urban area'' and ``rural area'' in Sec.  
412.62(f)(1)(ii) and Sec.  412.62 (f)(1)(iii) and Sec.  
412.64(b)(1)(ii)(A)-(C) which are found in Sec. Sec.  412.525(c), 
412.529(d)(4)(ii)(B) and (d)(4)(iii)(B), 412.534(d)(1), (f)(2)(ii), and 
(f)(3)(ii), and 412.536(c)(1), (e)(2)(ii), and (e)(3)(ii) would need to 
be replaced with references to Sec.  412.503. We are proposing to 
replace the above-described references with Sec.  412.503.

(We note that provisions of the Medicare, Medicaid, and SCHIP Extension 
Act of 2007, enacted on December 29, 2007 require a 3-year suspension 
of the payment adjustments at Sec.  412.534 to ``grandfathered LTCHs'' 
and application of Sec.  412.536 to ``freestanding'' LTCHs for cost 
reporting periods beginning on or after the date of enactment of the 
legislation. In addition, revisions to the short stay outlier policy, 
as well as other changes to the regulations necessitated by MMSEA will 
be addressed in a future notice.)

VI. Computing the Proposed Adjusted Federal Prospective Payments for 
the 2008 LTCH PPS Rate Year

    In accordance with Sec.  412.525 and as discussed in section IV.C. 
of this proposed rule, the standard Federal rate is adjusted to account 
for differences in area wages by multiplying the labor-related share of 
the standard Federal rate by the appropriate LTCH PPS wage index (as 
shown in Tables 1 and 2 of Addendum A to this proposed rule). The 
standard Federal rate is also adjusted to account for the higher costs 
of hospitals in Alaska and Hawaii by multiplying the nonlabor-related 
share of the standard Federal rate by the appropriate cost-of-living 
factor (shown in Table 3 in section IV.D.2 of this preamble). In the RY 
2008 LTCH PPS final rule (72 FR 4776), we established a standard 
Federal rate of $38,356.45 for the 2008 LTCH PPS rate year. In this 
proposed rule, based on the best available data and the proposed 
policies described in this proposed rule, we are proposing that the 
standard Federal rate for the 2009 LTCH PPS rate year would be 
$39,076.28 as discussed in section IV.C.3. of this preamble. We 
illustrate the methodology that would be used to adjust the proposed 
Federal prospective payments for the 2009 LTCH PPS rate year in the 
following examples:

    Example: During the 2009 LTCH PPS rate year, a Medicare patient 
is in a LTCH located in Chicago, Illinois (CBSA 16974). The proposed 
full LTCH PPS wage index value for CBSA 16974 is 1.0715 (see Table 1 
in Addendum A to this proposed rule). The Medicare patient is 
classified into MS-LTC-DRG 28 (Spinal Procedures with MCC), which 
has a current relative weight of 1.1417 (see Table 3 of Addendum A 
to this proposed rule).
    To calculate the LTCH's proposed total adjusted Federal 
prospective payment for this Medicare patient, we compute the 
proposed wage-adjusted Federal prospective payment amount by 
multiplying the proposed unadjusted standard Federal rate 
($39,076.28) by the proposed labor-related share (75.920 percent) 
and the proposed wage index value (1.0715). This proposed wage-
adjusted amount is then added to the nonlabor-related portion of the 
proposed unadjusted standard Federal rate (24.080 percent; adjusted 
for cost of living, if applicable) to determine the proposed 
adjusted Federal rate, which is then multiplied by the MS-LTC-DRG 
relative weight (1.1417) to calculate the proposed total adjusted 
Federal prospective payment for the 2009 LTCH PPS rate year 
($47,035.13). Table 6 illustrates the components of the calculations 
in this example.

                                 Table 6

VII. Monitoring

    In the August 30, 2002 final rule (67 FR 56014), we described an 
on-going monitoring component to the new LTCH PPS. Specifically, we 
discussed on-going analysis of the various policies that we believe 
would provide equitable payment for stays that reflect less than the 
full course of treatment and reduce the incentives for inappropriate 
admissions, transfers, or premature discharges of patients that are 
present in a discharge-based PPS. As a result of our data analysis, we 
have revisited a number of our original policies and have identified 
behaviors by certain LTCHs that lead to inappropriate Medicare 
payments.
    In the RY 2005 LTCH PPS final rule (69 FR 25692) we revised the 
interruption of stay policy. We also established a payment adjustment 
for LTCH HwHs and satellites in the FY 2005 IPPS final rule (69 FR 
49191 through 49214). In the RY 2008 final rule, at Sec.  412.536, 
based on additional data monitoring and analysis, we expanded this 
payment adjustment to apply to LTCHs and LTCH satellites that were not 
co-located with their referring hospitals.
    In the RY 2007 and 2008 final rules (71 FR 27798 and 72 FR 28670), 
we revised the SSO payment adjustment formula as a consequence of data 
analyses which indicated that Medicare was overpaying for certain SSO 
cases.
    Although at this time, we are not proposing any new payment 
adjustments that have resulted from our monitoring activity, we 
continue to pursue our on-going monitoring program that involves the 
CMS Office of Research and Development (ORDI), existing QIO monitoring, 
and studies described in the RY 2006 LTCH PPS final rule (70 FR 24211).

[[Page 5374]]

    As we discussed in the RY 2004 LTCH PPS final rule (68 FR 34157), 
the Medicare Payment Advisory Commission (MedPAC) endorsed our 
monitoring activity. Furthermore, the Commission pursued an independent 
research initiative that led to a section in MedPAC's June 2004 Report 
to Congress entitled ``Defining long-term care hospitals''. This study 
included recommendations that we develop facility and patient criteria 
for LTCH admission and treatment and that we require a review by QIOs 
to evaluate whether LTCH admissions meet criteria for medical necessity 
once the recommended facility and patient criteria are established (70 
FR 24210). In response to the recommendation in MedPAC's June 2004 
Report, we awarded a contract to Research Triangle Institute, 
International (RTI), on September 27, 2004, to conduct a thorough 
examination of the feasibility of implementing MedPAC's 
recommendations.
    Both Part 1 and Part 2 of the RTI Report are available on our Web 
site at http://www.cms.hhs.gov/LongTermCareHospitalPPS/02a_RTIReports.asp#TopOfPage. We also included the Executive Summary of 
RTI's final report in Addendum B of the RY 2008 proposed rule (72 FR 
4884 through 4886). (A comprehensive discussion of RTI's continuing 
work is included at section XI of this proposed rule.)

VIII. Method of Payment

    Under Sec.  412.513, a Medicare LTCH patient is classified into a 
MS-LTC-DRG based on the principal diagnosis, up to eight additional 
(secondary) diagnoses, and up to six procedures performed during the 
stay, as well as age, sex, and discharge status of the patient. The MS-
LTC-DRG is used to determine the Federal prospective payment that the 
LTCH will receive for the Medicare-covered Part A services the LTCH 
furnished during the Medicare patient's stay. Under Sec.  412.541(a), 
the payment is based on the submission of the discharge bill. The 
discharge bill also provides data to allow for reclassifying the stay 
from payment at the full MS-LTC-DRG rate to payment for a case as a SSO 
(under Sec.  412.529) or as an interrupted stay (under Sec.  412.531), 
or to determine if the case will qualify for a HCO payment (under Sec.  
412.525(a)).
    Accordingly, the ICD-9-CM codes and other information used to 
determine if an adjustment to the full MS-LTC-DRG payment is necessary 
(for example, LOS or interrupted stay status) are recorded by the LTCH 
on the Medicare patient's discharge bill and submitted to the Medicare 
FI for processing. The payment represents payment in full, under Sec.  
412.521(b), for inpatient operating and capital-related costs, but not 
for the costs of an approved medical education program, bad debts, 
blood clotting factors, anesthesia services by hospital-employed 
nonphysician anesthetists or the costs of photocopying and mailing 
medical records requested by a Quality Improvement Organization (QIO), 
which are costs paid outside the LTCH PPS.
    As under the previous reasonable cost-based payment system, under 
Sec.  412.541(b), a LTCH may elect to be paid using the periodic 
interim payment (PIP) method described in Sec.  413.64(h), based on the 
estimated prospective payment for the year, and may be eligible to 
receive accelerated payments as described in Sec.  413.64(g). We 
exclude HCO payments that are paid upon submission of a discharge bill 
from the PIP amounts. In addition, Part A costs that are not paid for 
under the LTCH PPS, including Medicare costs of an approved medical 
education program, bad debts, blood clotting factors, anesthesia 
services by hospital-employed nonphysician anesthetists and the costs 
of photocopying and mailing medical records requested by a QIO, are 
subject to the interim payment provisions as specified in Sec.  
412.541(c).
    Under Sec.  412.541(d), LTCHs with unusually long lengths of stay 
that are not receiving payment under the PIP method may bill on an 
interim basis (60 days after an admission and at intervals of at least 
60 days after the date of the first interim bill) and this should 
include any HCO payment determined as of the last day for which the 
services have been billed.

IX. RTI's Research

    With the recommendations of MedPAC's June 2004 Report to Congress 
as a point of departure, we awarded a contract to Research Triangle 
Institute, International (RTI) at the start of FY 2005 for a 
comprehensive evaluation of the feasibility of developing patient and 
facility level characteristics for LTCHs that could distinguish LTCH 
patients from those treated in other hospitals.
    RTI completed this project in two phases. In Phase I, RTI prepared 
a background report summarizing existing information regarding LTCHs' 
current role in the Medicare system: their history as Medicare 
participating providers; the types of patients they treat; the criteria 
QIOs currently use to review appropriateness of care in these settings; 
and the types of regulations they face as Medicare participating 
providers. This work reviewed prior analyses of these issues and 
included discussions with MedPAC, other researchers, CMS, the QIOs, and 
the hospital associations.
    In Phase II, RTI collected additional information on tools 
currently used by the QIOs and the industry to assess patient 
appropriateness for admission; analyzed claims to understand 
differences between short term acute care hospital patients with 
outlier stays who were subsequently treated in LTCHs compared to those 
who were not and differences between patients who continued treatment 
as outliers in acute care hospitals with patients who had been admitted 
to LTCH with the same DRGs; and visited different types of hospitals to 
observe first-hand how LTCH patients differ from those in other 
settings and how this pattern varies in different parts of the country. 
RTI worked with different associations, including the National 
Association of Long Term Hospitals (NALTH), the Acute Long Term 
Hospital Association (ALTHA), the American Hospital Association (AHA), 
and the American Medical Rehabilitation Providers Association (AMRPA), 
as well as several of the larger LTCH chains. The final report for 
those phases submitted by RTI summarizes these efforts and makes 
recommendations to CMS regarding LTCHs.
    (We have posted the reports on both Phase I and Phase II of RTI's

    In summary, RTI's research has resulted in an extensive and careful 
analysis of the Medicare populations served by LTCHs, a comparison of 
these populations with those treated in other acute settings, including 
IPPS, IRFs, and Inpatient Psychiatric populations, as well as those 
treated in less intensive settings such as SNFs. This work included 
analysis of Medicare data to compare patient characteristics and 
provider costs for certain types of patients; regulatory requirements 
governing program conditions of participation for these different types 
of facilities; interviews with private sector developers of level of 
care determinations; and site visits and interviews with physicians 
treating these typical and frequently overlapping populations.
    The results suggested that while there are some patients who 
require very long term acute care hospitalization there are also many 
patients whose LOS at the LTCH may trigger a short stay outlier 
payment, suggesting that not all LTCH admissions had a LOS consistent 
with

[[Page 5375]]

the need for prolonged acute care hospitalization in an LTCH. While 
existing patient criteria such as Interqual are useful for 
distinguishing between the need for hospital-level treatment and a less 
intensive level, such as SNF care, RTI's analysis has determined that, 
in fact, the private sector criteria failed to distinguish between 
patients at LTCHs and patients at acute care hospitals. The criteria 
proposed by the National Association for Long Term Hospitals (NALTH) 
also had this shortcoming. While they identified the acute care 
patient, they failed to identify differences between LTCH admissions' 
clinical characteristics and those treated in a general acute care 
hospital, in either a step down unit, or in some cases, a general 
medical/surgery unit.
    On January 30, 2007, RTI convened a Technical Expert Panel (TEP) 
comprised of physicians, nurses, and hospital administrators 
representing, LTCHs, acute care hospitals, IRFs, and SNFs, all of which 
represent the range of inpatient settings for treating medically 
complex patients. The goal of this meeting was to identify a set of 
clinical indicators that distinguish between the medically complex 
populations at LTCHs and acute care hospitals , including ICU, step-
down, and general acute care. The panelists examined severity measures 
and treatment needs for medically complex patients to define the point 
at which ICU or acute care patients become appropriate for care at 
LTCHs. They focused on patient criteria currently used by some 
providers and QIOs. Presentations described existing systems for 
identifying medical complexity and severity of illness for a particular 
patient. In exchanges between the presenters and panel members , 
however, acute care hospital physicians stated that acute care 
hospitals treated severely ill patients with medically complex 
conditions for their entire episode of care and that these measures 
were not useful for determining whether the patient should be treated 
in an acute care hospital or a LTCH. After discussion, the TEP 
participants reached a consensus that LTCHs provide a service that is 
comparable to general acute step-down units and is not unique to LTCHs.
    Discussions with LTCH physicians and acute care hospital physicians 
practicing in areas that lack LTCHs confirmed the results of RTI's data 
analyses in demonstrating the widespread overlap in the patient 
populations treated in LTCHs and those treated in acute care hospitals. 
Though representatives from the LTCHs clearly described the medical 
complexity and severity of illness of their patient populations, much 
of the difference between the LTCH and acute hospital patient 
populations was driven by geography and access to LTCH facilities. In 
the many areas of the country without access to LTCH services, acute 
hospitals treat the medically complex patients and receive an acute 
hospital IPPS payment, or outlier payment in cases where the costs of 
care are very high, rather than the much higher LTCH payment. As a 
result of the discussion, claims by the LTCH industry that medically 
complex patients treated in LTCHs were significantly different from 
medically complex patients treated in acute settings were not 
confirmed, though panel members did agree that more work may need to be 
done to measure outcomes for medically complex patients treated in each 
of these settings. There was also consensus among the panelists that 
quality of care was related to treating a sufficient volume of these 
difficult cases, regardless of provider setting.
    On November 6, 2007, RTI convened a second TEP based upon the 
earlier meeting and participant responses. As with the first TEP, panel 
members included LTCH physicians and administrators, acute care 
physicians in areas without LTCHs (for example, New York and northern 
New England), physicians from SNFs in areas without LTCHs, and several 
IRF physicians.
    There was an intentional focus at the second TEP on Medicare 
patients with respiratory conditions requiring mechanical ventilation 
(vent patients). RTI presented data showing the mechanical ventilator 
patients were relatively homogenous in their likelihood of using LTCHs 
whereas the medically complex (respiratory) patients were much more 
diverse in their distributions making it more difficult to develop 
measurable medical parameters and widely accepted treatment protocols 
for this group. However, it was acknowledged that ventilator patients 
(referred to as ``vent patients'' in the following discussion) comprise 
less than 15 percent of all LTCH patients. RTI believed that the 
category of ``medically complex'' cases was too amorphous and the focus 
on vent patients would allow for more meaningful comparisons between 
the provider types. Nationwide, vent patients are treated in acute care 
hospitals and in LTCHs while some IRFs and SNFs accept and treat this 
group of patients. (We would also note that, as MedPAC found in its 
June, 2004 Report to Congress, the highest predictor of LTCH use is 
whether a patient has had a tracheotomy which is common in long-term 
ventilator-dependent patients. (p. 125))
    RTI presented two analyses of Medicare claims data based on 
episodes of care constructed for beneficiaries with vent-related DRGs 
during their initial (acute) admission. The first analysis compared 
outcomes for patients living in areas with LTCHs, to outcomes for 
clinically similar patients living in geographically comparable areas 
that had no LTCHs. The second examined episodes of care only for 
beneficiaries in specific states with several LTCHs, and compared 
outcomes for clinically similar cases that remained in the acute care 
setting with those that were referred to an LTCH. Both analyses used a 
``propensity score approach'' which groups patients according to the 
clinical and demographic characteristics that predict LTCH referral.
    The first analysis found that there was very little difference in 
average episode length, Medicare cost, mortality or length of time 
before being discharged home, between areas that have LTCHs and those 
that do not. The second analysis found that results differed between 
cases with the highest probability of using LTCHs (those medically 
complex vent cases with tracheotomies, longer prior ICU stays), and 
ventilator cases with lower probability of using LTCHs. In the small 
group with a high likelihood, mortality was lower and the 60-day 
likelihood of being discharged home was higher for those referred to 
LTCHs than for those staying in acute settings, while Medicare payments 
were the same or less. Among the less complex cases, however, RTI found 
that LTCH referral was associated with much higher costs and same or 
worse performance in other outcome measures. These findings are very 
similar to those noted by MedPAC in the Commission's June 2004 Report 
to the Congress. (p. 126-127).
    RTI also asked TEP members to evaluate 6 case vignettes and assess 
which patients were appropriate for admission to their type of 
facility. The case vignettes consisted of detailed medical histories of 
two ventilator-dependent patients admitted for weaning, two wound care 
patients, and two ``medically complex'' patients.
    The TEP indicated that there were significant differences between 
the level of patient morbidity that the acute care hospitals and LTCHs 
would admit and treat as compared to the IRFs and also the SNFs, but 
that LTCH patients and patients treated in IPPS acute care hospital 
step-down units were virtually indistinguishable. In further discussion 
of individual case vignettes, LTCH and

[[Page 5376]]

acute care hospital physicians were in accord regarding appropriate 
therapeutic dispositions for the stabilized, post-ICU ``critical care'' 
patients and they agreed that such patients could be appropriately 
treated in either acute care hospital step-down units or in LTCHs. 
Therefore, although there was consensus regarding the medical profile 
of such patients, it was also noted by one acute care physician that 
this indicated that ``there is no such thing as an LTCH-only patient.'' 
On the other hand, acute care hospital physicians noted that typically, 
in their facilities, their step-down units may take a slightly less 
stable ``critical care'' patient than would be treated in a LTCH, that 
is, patients that may have some unresolved medical issues still being 
diagnosed especially if there was a need to free-up an ICU bed. This 
was possible because such a patient would continue treatment by the 
same physicians and have access to the full range of acute care 
hospital services but also could return to the ICU without significant 
difficulty, if necessary.
    The panelists also discussed a realistic definition of patient 
stability for ``critical care'' patients in different settings and 
whether this was typically based upon ``vital signs,'' dependence on 
``pressors,'' (intravenous drugs administered to raise blood pressure) 
or whether patient stability was based on a physician's subjective 
determination (for example, ``I know it when I see it''). There was 
additional clinically-oriented discussion of measures of medical 
stability. (It was also noted that while some of the ``medically 
complex'' patients currently being treated in LTCHs would fall into the 
``critical care'' category, this is not the case for all of their 
patients.)
    Panelists also addressed the intensity of nursing care required by 
a ``critical care'' patient and the central role of the nurse to 
patient ratio in identifying the level of care offered in a hospital. 
Both LTCHs and IPPS step-down units typically have a RN to patient 
ratio of 1-to-4 or 1-to-5. LTCH physicians emphasized the value of the 
LTCH ``team approach'' to patient care to the agreement of the TEP's 
acute care hospital physicians who noted that this approach is also the 
model that is in place in their facilities. One physician noted that he 
had little doubt that a ``critical care'' patient hospitalized at any 
of the acute care hospitals or LTCHs represented at the TEP would 
receive an equivalent and high level of treatment.
    Members of the panel also indicated that discharges from acute care 
hospitals to LTCHs (in areas where this is an option) often occur 
because the LTCH is known to provide specialized treatment for 
particular types of patients. It was also noted, however, that 
commonly, hospital resources drive patient placement regarding the 
treatment of very sick and expensive patients when there is an LTCH 
placement option.
    Following the above exchanges, it was widely acknowledged by 
panelists that measures distinguishing appropriate LTCH patients from 
patients being treated in step-down units of acute care hospitals were 
not going to be developed by the TEP. There were serious questions 
raised as to whether developing such a product was even feasible. The 
group concurred on the recommendations, listed below, for a treatment 
model for the type of ``critical care'' patients who had been the focus 
of TEP:
     CMS should pay similar rates for similar patients 
regardless of setting if certain objective parameters associated with 
patient care were present, among which were:
    ++ A critical mass of patients with the targeted conditions to 
ensure sufficient experience in those areas for the health 
professionals in that setting;
    ++ Patient-level criteria to identify appropriate cases for this 
level of care, applicable regardless of setting;
    ++ Quality of care should be based on structure and process 
standards;
    ++ Interdisciplinary teams with physician leads, appropriate nurse 
staffing levels; and inclusion of treating therapists (for example, 
physical, respiratory, occupational);
     Both LTCHs and these IPPS step-down units meeting these 
standards could be recognized as ``Centers of Excellence'' for patients 
defined as critically ill.
    TEP members decided not to include ``patient outcomes'' on the list 
of recommendations because of concerns that a facility's recognition 
and/or payment based on patient outcomes could lead to ``cherry-
picking'' of less sick patients which could lead to access problems for 
otherwise appropriate patients.
    In summary, there was a consensus at the end of RTI's second TEP 
that LTCHs treat patients who are also treated by acute care hospitals. 
The ``critical care'' post-ICU patient who LTCHs describe as their 
targeted patient are treated throughout most of the country in acute 
care hospital step-down units. The interdisciplinary team treatment 
model is the standard both in many LTCHs and in many acute care 
hospitals with step-down units. While by definition, the patients 
appropriate for treatment in a LTCH require hospital-level care (as 
opposed to SNF level), it is not clear that any criteria can be 
developed which identifies patients who belong in a LTCH exclusively.
    RTI will continue to work on these issues in preparing its final 
report. The results thus far have shown empirically, that LTCHs treat 
medically stable but critically ill patients that are clinically 
indistinguishable from those treated in step-down units of acute care 
hospitals. The work has also confirmed earlier research showing that 
for cases other than the vent patients discussed above in this section, 
that in the absence of compelling data on patient outcomes, that 
treatment at an LTCH is less cost-effective for the same DRGs than is 
treatment at acute care hospitals for the same DRGs.
    These TEPs have been important for furthering the discussion 
regarding the feasibility of developing unique criteria for LTCH 
patients. Over the past few years, the clinicians have agreed that 
LTCHs specialize in treating critically ill patients with multiple 
comorbidities and other longer term, acute level needs. This consensus 
contributes to identifying an appropriate LTCH patient by acuity of 
illness as well as LOS. Over the next few months, RTI will continue 
working with the clinical community to make recommendations regarding 
payment and treatment of critically ill patients, particularly in 
LTCHs. Further work will expand on the Centers of Excellence concept to 
examine the structure and process needed for such a designation. 
Additional analysis will examine the relative costs and payments for 
these patients under different payment systems.

XI. Regulatory Impact Analysis

[If you choose to comment on issues in this section, please include the 
caption ``IMPACT'' at the beginning of your comments.]

A. Introduction

    We have examined the impacts of this proposed rule as required by 
Executive Order 12866 (September 1993, Regulatory Planning and Review), 
the Regulatory Flexibility Act (RFA) (September 19, 1980, Pub. L. 96-
354), section 1102(b) of the Act, the Unfunded Mandates Reform Act of 
1995

[[Page 5377]]

(UMRA) (Pub. L. 104-4), and Executive Order 13132.
1. Executive Order 12866
    Executive Order 12866 (as amended by Executive Order 13258) directs 
agencies to assess all costs and benefits of available regulatory 
alternatives and, if regulation is necessary, to select regulatory 
approaches that maximize net benefits (including potential economic, 
environmental, public health and safety effects, distributive impacts, 
and equity). A regulatory impact analysis (RIA) must be prepared for 
major rules with economically significant effects ($100 million or more 
in any one year). In the impact analysis, we are using the proposed 
rates, factors and policies presented in this proposed rule, including 
updated proposed wage index values, and the best available claims and 
CCR data to estimate the change in proposed payments for the 2009 LTCH 
PPS rate year. As stated in section I.A. of this preamble section 
114(e)(1) of the MMSEA at the new section 1886(m)(2) to the Act revises 
the standard Federal rate for RY 2008 by providing that the base rate 
for RY 2008 shall be the same as the base rate for RY 2007 (in other 
words, the standard Federal rate for RY 2008 is the same as the 
standard Federal rate for 2007). Also, section 114(e)(2) of the MMSEA 
provides that the revised rate does not apply to discharges occurring 
on or after July 1, 2007, and before April 1, 2008. As noted in section 
IV.E. of this preamble, the standard Federal rate for RY 2007 was 
$38,086.04. Furthermore, we note that section 114(c)(3) of MMSEA 
requires a 3-year suspension of our implementation of the revisions to 
the SSO policy at Sec.  412.529(c)(3)(i) that was finalized in the RY 
2008 final rule. Both of these revisions to RY 2008 LTCH PPS payments 
(that is, sections 114(c)(3) and (e)(1) through (2) of MMSEA) affect 
the modeling of payments in this impact analysis, which we will discuss 
in greater detail in section XVI.B.3. of this proposed rule. Based on 
the best available data for 394 LTCHs, we estimate that the proposed 
update to the standard Federal rate for RY 2009 (discussed in section 
IV.C. of the preamble of this proposed rule) and the proposed changes 
to the area wage adjustment (discussed in section IV.F.1. of the 
preamble of this proposed rule), for the 2009 LTCH PPS rate year, in 
addition to an estimated increase in short-stay and high cost outlier 
payments (as discussed in greater detail below) would result in an 
increase in estimated payments from the 2008 LTCH PPS rate year of 
approximately $124 million (or about 2.9 percent) for the 394 LTCHs in 
our database. Based on the 394 LTCHs in our database, we estimate RY 
2008 LTCH PPS payments to be approximately $4.32 billion and RY 2009 
LTCH PPS payments to be approximately $4.44 billion. Because the 
combined distributional effects and estimated changes to the Medicare 
program payments would be greater than $100 million, this proposed rule 
would be considered a major economic rule, as defined in this section. 
We note the approximately $124 million for the projected increase in 
estimated aggregate LTCH PPS payments resulting from the provisions 
presented in this proposed rule does not reflect changes in LTCH 
admissions or case-mix intensity in estimated LTCH PPS payments, which 
would also affect overall payment changes. (We note that due to 
rounding, the approximation of $124 million is closer to the projected 
increase in estimated aggregate LTCH PPS payments than the difference 
between the approximately $4.44 billion and approximately $4.32 billion 
in estimated RY 2008 and RY 2009 LTCH PPS payments, respectively.)
    We note that the average combined effect of the proposed standard 
Federal rate and area wage adjustment changes on estimated aggregate 
payments cannot be computed by simply adding up the estimated averages 
in columns 6 and 7 of Table 9 because each of those two columns are 
intended to show the isolated impact of the respective proposed change 
(that is, the proposed change to the standard Federal rate or the 
proposed change to the area wage adjustment) on estimated payments for 
RY 2009 as compared to RY 2008, and the interactive effects resulting 
from both the proposed change to the standard Federal rate and proposed 
change to the area wage adjustment are not accounted for in the 
modeling of estimated payments to produce the percent change in each of 
these columns. However, the interactive effects of all proposed changes 
are taken into account in the modeling of estimated payments for RY 
2009 as compared to RY 2008 in Column 8 of Table 9. Notwithstanding 
this limitation in comparing the various columns in Table 9, the 
difference between the projected increase in payments per discharge 
from RY 2008 to RY 2009 for all changes of 2.9 percent (column 8) and 
the sum of the projected increase due to proposed change to the 
standard Federal rate (2.2 percent in column 6) and the proposed change 
due to the area wage adjustment (-0.1 percent in column 7) of 2.1 
percent (that is, 2.2 percent + (-0.1 percent) = 2.1 percent) is mostly 
attributable to the effect of the estimated increase in payments for 
HCO and SSO cases in RY 2009 as compared to RY 2008. That is, in 
calculating the estimated increase in payments from RY 2008 to RY 2009 
for HCO and SSO cases, we increased estimated costs by the applicable 
proposed market basket (approximately 3.5 percent). We note, SSO cases 
comprise approximately 16 percent of estimated total LTCH PPS payments 
and HCO cases comprise approximately 8 percent of estimated total LTCH 
PPS payments. The vast majority of the payments for SSO cases (over 80 
percent) are based on the estimated cost of the case.
    While the effects of the estimated increase in SSO and HCO payments 
and the proposed change to the standard Federal rate which are 
projected to increase estimated payments per discharge from RY 2008 to 
RY 2009, the proposed changes to the area wage adjustment from RY 2008 
to RY 2009 are expected to result in a small decrease of 0.1 percent in 
estimated aggregate LTCH PPS payments from the 2008 LTCH PPS rate year 
to the 2009 LTCH PPS rate year (see column 7 of Table 9). As discussed 
in section IV.F.1. of this proposed rule, we are proposing to update 
the wage index values for RY 2009 based on the most recent available 
data. In addition, we are proposing to increase the labor-related share 
from 75.788 percent to 75.920 percent under the LTCH PPS for RY 2009 
based on the most recent available data on the relative importance of 
the labor-related share of operating and capital costs of the market 
basket applicable to the LTCH PPS (also discussed in section IV.F.1. of 
this proposed rule).
2. Regulatory Flexibility Act (RFA)
    The RFA requires agencies to analyze options for regulatory relief 
of small entities. For purposes of the RFA, small entities include 
small businesses, nonprofit organizations, and small governmental 
jurisdictions. Most hospitals and most other providers and suppliers 
are small entities, either by nonprofit status or by having revenues of 
$6.5 million to $31.5 million in any 1 year. For further information, 
see the Small Business Administration's regulation at 70 FR 72577, 
December 6, 2005. Individuals and States are not included in the 
definition of a small entity. Because we lack data on individual 
hospital receipts, we cannot determine the number of small proprietary 
LTCHs. Therefore, we assume that all LTCHs are considered small 
entities for the purpose of the analysis that follows. Medicare FIs are 
not considered to be small entities. The

[[Page 5378]]

Secretary certifies that this proposed rule would not have a 
significant economic impact on a substantial number of small entities.
    Currently, our database of 394 LTCHs includes the data for 88 non-
profit (voluntary ownership control) LTCHs and 265 proprietary LTCHs. 
Of the remaining 41 LTCHs, 25 LTCHs are Government-owned and operated 
and the ownership type of the other 16 LTCHs is unknown (as shown in 
Table 9). The impact of the proposed payment rate and policy changes 
for the 2009 LTCH PPS rate year (including the proposed update to the 
standard Federal rate and the proposed changes to the area wage 
adjustment) is discussed in section XVI.B.4.c. of this proposed rule.
    As we discuss in detail throughout the preamble of this proposed 
rule, based on the most recent available LTCH data, we believe that the 
provisions of this proposed rule would result in an increase in 
estimated aggregate LTCH PPS payments and that the resulting LTCH PPS 
payment amounts result in appropriate Medicare payments.
    The impact analysis of the proposed payment rate and policy changes 
in Table 9 shows that estimated payments per discharge are expected to 
increase approximately 2.9 percent, on average, for all LTCHs from the 
2008 LTCH PPS rate year as compared to the 2009 LTCH PPS rate year. We 
are proposing a 2.6 percent increase to the standard Federal rate for 
RY 2009 (as discussed in section IV.E. of this proposed rule). The 
projected 2.9 percent increase in estimated payments per discharge from 
the 2008 LTCH PPS rate year to the 2009 LTCH PPS rate year is 
attributable to the proposed change to the rate, the area wage 
adjustment (discussed in section IV.F.1. of this proposed rule) and 
estimated increases in short-stay outlier (SSO) and high cost outlier 
(HCO) payments (as discussed in greater detail below). That is, as 
Table 9 shows, the proposed change to the standard Federal rate is 
projected to result in an estimated average increase of 2.2 percent in 
estimated payments per discharge from RY 2008 to RY 2009, on average, 
for all LTCHs, while the proposed changes to the area wage adjustment 
are projected to result in an estimated decrease of 0.1 percent, on 
average, for all LTCHs (columns 6 and 7 of Table 9, respectively). A 
thorough discussion of the regulatory impact analysis for the proposed 
changes presented in this proposed rule can be found below in section 
XVI.B.3. of this proposed rule.
3. Impact on Rural Hospitals
    For purposes of section 1102(b) of the Act, we define a small rural 
hospital as a hospital that is located outside of a Metropolitan 
Statistical Area and has fewer than 100 beds. As shown in Table 9, we 
are projecting a 2.6 percent increase in estimated payments per 
discharge from the 2008 LTCH PPS rate year as compared to the 2009 LTCH 
PPS rate year for rural LTCHs as a result of the proposed changes 
presented in this proposed rule (that is, the proposed update to the 
standard Federal rate discussed in section IV.E. of the preamble of 
this proposed rule and the proposed changes to the area wage adjustment 
as discussed in section IV.F.1. of the preamble of this proposed rule) 
based on the data of the 25 rural LTCHs in our database of 394 LTCHs 
for which complete data were available.
    As shown in Table 9, the estimated increase in estimated LTCH PPS 
payments from the 2008 LTCH PPS rate year as compared to the 2009 LTCH 
PPS rate year for rural LTCHs is primarily due to the proposed update 
to the standard Federal rate (as discussed in greater detail in section 
IV.E. of the preamble of this proposed rule) and the proposed change in 
the area wage adjustment (as discussed in greater detail in section 
V.F.1. of the preamble of this proposed rule) in conjunction with the 
estimated increased payments for SSO and HCO cases (as discussed below 
in section XVI.B.3. of this proposed rule). We believe that the changes 
to the area wage adjustment presented in this proposed rule (that is, 
the proposed use of updated wage data and the proposed change in the 
labor-related share) would result in accurate and appropriate LTCH PPS 
payments in RY 2009 since they are based on the most recent available 
data. Such updated data appropriately reflect national differences in 
area wage levels and identifies the portion of the proposed standard 
Federal rate that should be adjusted to account for such differences in 
area wages, thereby resulting in accurate and appropriate LTCH PPS 
payments.
4. Unfunded Mandates
    Section 202 of the Unfunded Mandates Reform Act of 1995 (UMRA) also 
requires that agencies assess anticipated costs and benefits before 
issuing any rule whose mandates require spending in any one year of 
$100 million in 1995 dollars, updated annually for inflation. That 
threshold level is currently approximately $120 million. This proposed 
rule would not mandate any requirements for State, local, or tribal 
governments, nor would it result in expenditures by the private sector 
of $120 million or more in any 1 year.
5. Federalism
    Executive Order 13132 establishes certain requirements that an 
agency must meet when it publishes a proposed rule (and subsequent 
final rule) that imposes substantial direct requirement costs on State 
and local governments, preempts State law, or otherwise has Federalism 
implications.
    We have examined this proposed rule under the criteria set forth in 
Executive Order 13132 and have determined that this proposed rule would 
not have any significant impact on the rights, roles, and 
responsibilities of State, local, or tribal governments or preempt 
State law, based on the 25 State and local LTCHs (that is, Government 
ownership type) in our database of 394 LTCHs for which data were 
available.
6. Alternatives Considered
    In the preamble of this proposed rule, we are setting forth the 
proposed annual update to the payment rates for the LTCH PPS for RY 
2009. In this preamble, we specify the statutory authority for the 
provisions that are presented, identify those proposed policies when 
discretion has been exercised, and present rationale for our decisions 
as well as alternatives that were considered, and solicit comments on 
suggested alternatives from commenters (where relevant).

B. Anticipated Effects of Proposed Payment Rate Changes

    We discuss the impact of the proposed changes to the payment rates, 
factors, and other payment rate policies presented in the preamble of 
this proposed rule in terms of their estimated fiscal impact on the 
Medicare budget and on LTCHs.
1. Budgetary Impact
    Section 123(a)(1) of the BBRA requires that the PPS developed for 
LTCHs ``maintain budget neutrality.'' We believe that the statute's 
mandate for budget neutrality (BN) applies only to the first year of 
the implementation of the LTCH PPS (that is, FY 2003). Therefore, in 
calculating the FY 2003 standard Federal rate under Sec.  
412.523(d)(2), we set total estimated payments for FY 2003 under the 
LTCH PPS so that estimated aggregate payments under the LTCH PPS are 
estimated to equal the amount that would have been paid if the LTCH PPS 
had not been implemented.

[[Page 5379]]

2. Impact on Providers
    The basic methodology for determining a per discharge LTCH PPS 
payment is set forth in Sec.  412.515 through Sec.  412.536. In 
addition to the basic MS-LTC-DRG payment (standard Federal rate 
multiplied by the MS-LTC-DRG relative weight), we make adjustments for 
differences in area wage levels, COLA for Alaska and Hawaii, and SSOs. 
Furthermore, LTCHs may also receive HCO payments for those cases that 
qualify based on the threshold established each rate year.
    To understand the impact of the proposed changes to the LTCH PPS 
payments discussed in section IV. of this proposed rule on different 
categories of LTCHs for the 2009 LTCH PPS rate year, it is necessary to 
estimate payments per discharge for the 2008 LTCH PPS rate year using 
the rates, factors and policies established in the RY 2008 LTCH PPS 
final rule (72 FR 26870 through 27029), the RY 2008 LTCH PPS correction 
notice (72 FR 36613 through 36616) and the applicable sections of MMSEA 
(as described in greater detail below in section XVI.B.3. of this 
proposed rule). It is also necessary to estimate the proposed payments 
per discharge that would be made under the proposed LTCH PPS rates, 
factors and policies for the 2009 LTCH PPS rate year (as discussed in 
the preamble of this proposed rule). We also evaluated the change in 
estimated 2008 LTCH PPS rate year payments to estimated proposed 2009 
LTCH PPS rate year payments (on a per discharge basis) for each 
category of LTCHs.
    Hospital groups were based on characteristics provided in the OSCAR 
data, FY 2003 through FY 2005 cost report data in HCRIS, and PSF data. 
Hospitals with incomplete characteristics were grouped into the 
``unknown'' category. Hospital groups include the following:
     Location: Large Urban/Other Urban/Rural.
     Participation date.
     Ownership control.
     Census region.
     Bed size.
    To estimate the impacts of the proposed payment rates and policy 
changes among the various categories of existing providers, we used 
LTCH cases from the FY 2006 MedPAR file to estimate payments for RY 
2008 and to estimate proposed payments for RY 2009 for 394 LTCHs. While 
currently there are just under 400 LTCHs, the most recent growth is 
predominantly in for-profit LTCHs that provide respiratory and 
ventilator-dependent patient care. We believe that the discharges from 
the FY 2006 MedPAR data for the 394 LTCHs in our database, which 
includes 265 proprietary LTCHs, provide sufficient representation in 
the MS-LTC-DRGs containing discharges for patients who received LTCH 
care for the most commonly treated LTCH patients' diagnoses.
3. Calculation of Prospective Payments
    For purposes of this impact analysis, to estimate per discharge 
payments under the LTCH PPS, we simulated payments on a case-by-case 
basis using LTCH claims for the FY 2006 MedPAR files. In modeling 
estimated LTCH PPS payments for both RY 2008 and RY 2009 in this impact 
analysis, we applied the RY 2008 standard Federal rate (that is, 
$38,086.04) provided for by sections 114(e)(1) and (2) of Public Law 
110-173, and the SSO policy provided for by section 114(c)(3) of the 
MMSEA7 (that is, excluding the revisions to the SSO policy at Sec.  
412.529(c)(3)(i) of the regulations). Although we realize that the 
effective date for the change in the SSO policy during RY 2008 in the 
MMSEA is December 29, 2007, and the revised standard Federal rate for 
RY 2008 is not applicable for discharges occurring on or after July 1, 
2007 and before April 1, 2008, for purposes of this impact analysis, in 
estimating RY 2008 LTCH PPS payments we applied both the revised SSO 
policy and revised standard Federal rate for all of RY 2008. Similarly, 
in modeling LTCH PPS payments to project the average change in 
estimated payments per discharge from RY 2008 to RY 2009 due to the 
proposed change in the standard Federal rate (column 6 of Table 9), 
rather than using the RY 2008 standard Federal rate finalized in the RY 
2008 final rule, we compared the RY 2008 ``base rate'' (which we 
interpret to mean the standard Federal rate) mandated by section 
114(e)(1) of the Medicare, Medicaid and SCHIP Extension Act of 2007 
(that is, $38,086.04), to the proposed RY 2009 standard Federal rate of 
$39,076.28 (that is, $38,086.04 updated by 2.6 percent, as discussed in 
section IV.E. of this proposed rule) in order to appropriately estimate 
the effect of updating the rate by 2.6 percent. We took this approach 
for the impact analysis in this proposed rule since for the last 3 
months of the 2008 LTCH PPS rate year (that is, April 2008 through June 
2008), which is the 3-month period immediately preceding the start of 
the 2009 LTCH PPS rate year, LTCHs will be paid in accordance with the 
RY 2008 standard Federal rate and SSO policy established by section 114 
of the Medicare, Medicaid, and SCHIP Extension Act of 2007. Therefore, 
for purposes of the impact analysis in this proposed rule, we modeled 
the projected changes in estimated payments from RY 2008 to RY 2009 
based on computing estimated RY 2008 LTCH PPS payments using a standard 
Federal rate of $38,086.04 and the corresponding change to the SSO 
policy, which excludes the revisions to the SSO policy at Sec.  
412.529(c)(3)(i), as if those policies were applicable to all 
discharges occurring during RY 2008. (Additional information on section 
114 of the Medicare, Medicaid and SCHIP Extension Act of 2007 can be 
found at section I.A. of this proposed rule.)
    Furthermore, in modeling estimated LTCH PPS payments for both RY 
2008 and RY 2009 in this impact analysis, we applied the RY 2008 and 
proposed RY 2009 adjustments for area wage differences (as described in 
section IV.F.1. of the preamble of this proposed rule), and the COLA 
for Alaska and Hawaii (as described in section IV.F.2. of the preamble 
of this proposed rule). Specifically, we adjusted for area wage 
differences for estimated 2008 LTCH PPS rate year payments using the 
current LTCH PPS labor-related share of 75.788 percent (72 FR 26892), 
the wage index values established in the Tables 1 and 2 of the Addendum 
of the RY 2008 final rule (72 FR 26996 through 27019) and the COLA 
factors established in Table 3 of the preamble of the RY 2008 final 
rule (72 FR 26894). Similarly, we adjusted for area wage differences 
for estimated 2009 LTCH PPS rate year payments using the proposed LTCH 
PPS labor-related share of 75.920 percent (see section IV.D.1.c. of 
this proposed rule), the proposed wage index values presented in the 
Tables 1 and 2 of the Addendum of this proposed rule and the proposed 
COLA factors established in Table 3 of the preamble of this proposed 
rule.
    As discussed above, we also accounted for the payment policy for 
SSOs. We also estimated additional payments that would be made for HCOs 
(as described in section IV.F.3. of this proposed rule). As noted in 
section IV.F.4. of this proposed rule, we are not proposing to make 
adjustments for rural location, geographic reclassification, indirect 
medical education costs, or a DSH payment for the treatment of low-
income patients because our most recent data analysis that reflects 
LTCH behavior subsequent to the implementation of the LTCH PPS 
indicates that proposing payment adjustments for geographic 
reclassification, rural location, DSH, or indirect medical education 
costs would not improve the accuracy of payments

made under the LTCH PPS to LTCHs. (See Section IV.F.4 ).
    These impacts reflect the estimated ``losses'' or ``gains'' among 
the various classifications of LTCHs for the 2008 LTCH PPS rate year 
compared to the 2009 LTCH PPS rate year based on the proposed payment 
rates and policy changes presented in this proposed rule. Table 9 
illustrates the estimated aggregate impact of the LTCH PPS among 
various classifications of LTCHs.
     The first column, LTCH Classification, identifies the type 
of LTCH.
     The second column lists the number of LTCHs of each 
classification type.
     The third column identifies the number of LTCH cases.
     The fourth column shows the estimated payment per 
discharge for the 2008 LTCH PPS rate year (as described above).
     The fifth column shows the estimated proposed payment per 
discharge for the 2009 LTCH PPS rate year (as described above).
     The sixth column shows the percentage change in estimated 
payments per discharge from the 2008 LTCH PPS rate year to the 2009 
LTCH PPS rate year for proposed changes to the standard Federal rate 
(as discussed in section IV.E. of the preamble of this proposed rule).
     The seventh column shows the percentage change in 
estimated payments per discharge from the 2008 LTCH PPS rate year to 
the 2009 LTCH PPS rate year for proposed changes to the area wage 
adjustment at Sec.  412.525(c) (as discussed in section IV.D.1. of the 
preamble of this proposed rule).
     The eighth column shows the percentage change in estimated 
payments per discharge from the 2008 LTCH PPS rate year (column 4) to 
the 2009 LTCH PPS rate year (column 5) for all proposed changes.

\2\ Estimated 2008 LTCH PPS rate year payments based on the rates, factors and policies established in the RY 2008 LTCH PPS final rule (72 FR 26870
  through 27029), the RY 2008 LTCH PPS correction notice (72 FR 36613 through 36616) and the applicable sections of the Medicare, Medicaid, and SCHIP
  Extension Act of 2007. As described in section XVI.B.3. of this proposed rule, although we are aware that there are different effective dates for the
  various provisions of MMSEA that affect RY 2008 LTCH PPS payments, for the purpose of this impact analysis, we modeled estimated RY 2008 payments as
  if those provisions were applicable to discharges for the entire 2008 LTCH PPS rate year. Specifically, in estimating RY 2008 LTCH PPS payments, we
  applied the RY 2008 Federal rate provided for by sections 114(e)(1) of the MMSEA (that is, $38,086.04), and the SSO policy provided for by section
  114(c)(3) of the MMSA (that is, excluding the revisions to the SSO policy at Sec.   412.529(c)(3)(i)).
\3\ Percent change in estimated payments per discharge from the 2008 LTCH PPS rate year to the 2009 LTCH PPS rate year for the proposed changes to the
  Federal rate, as discussed in section IV.E. of the preamble of this proposed rule. (Note, because about 34 percent of all LTCH cases are projected to
  receive a payment adjustment under the SSO policy that is based either on the estimated cost of the case or the ``blend option'' (which is based in
  part on the ``IPPS comparable amount'') rather than the proposed Federal rate in RY 2009, the percent change in estimated payments per discharge due
  to the proposed changes to the Federal rate for most of the categories of LTCHs, 2.2 percent, is somewhat less than the proposed update to the Federal
  rate of 2.6 percent.)
\4\ Percent change in estimated payments per discharge from the 2008 LTCH PPS rate year to the 2009 LTCH PPS rate year for proposed changes to the area
  wage adjustment at Sec.   412.525(c) (as discussed in section V.F.1. of the preamble of this proposed rule).
\5\ Percent change in estimated payments per discharge from the 2008 LTCH PPS rate year (as described in section XVI.B.3. of this proposed rule) to the
  2009 LTCH PPS rate year for all of the proposed changes presented in the preamble of this proposed rule. Note, this column, which shows the percent
  change in estimated payments per discharge for all proposed changes, may not equal the sum of the percent changes in estimated payments per discharge
  for proposed changes to the Federal rate (column 6) and the proposed changes to the area wage adjustment (column 7) due to the effect of estimated
  changes in both payments to SSO cases that are paid based on estimated costs and aggregate HCO payments (as discussed this proposed rule), as well as
  other interactive effects that cannot be isolated.

4. Results
    Based on the most recent available data (as described previously 
for 394 LTCHs), we have prepared the following summary of the impact 
(as shown in Table 9) of the proposed LTCH PPS payment rate and policy 
changes presented in this proposed rule. The impact analysis in Table 9 
shows that estimated payments per discharge are expected to increase 
approximately 2.9 percent, on average, for all LTCHs from the 2008 LTCH 
PPS rate year as compared to the 2009 LTCH PPS rate year as a result of 
the proposed payment rate and policy changes presented in this proposed 
rule. We note that although we are proposing a 2.6 percent increase to 
the standard Federal rate for RY 2009, based on the latest proposed 
market basket estimate (3.5 percent) and offset by the proposed coding 
and documentation adjustment (0.9 percent), for most categories of 
LTCHs, the impact analysis shown in Table 9 (column 7) only shows a 2.2 
percent increase in estimated payments per discharge from RY 2008 to RY 
2009 as a result of the proposed change to the standard Federal rate. 
The reason that this column shows an estimated 2.2 percent increase 
rather than an estimated 2.6 percent increase (based on the proposed 
2.6 percent update to the standard Federal rate) is because about 34 
percent of all LTCH cases are projected to receive an SSO payment that 
would be based either on the estimated cost of the case or the ``blend 
option'' (which is based in part on the ``IPPS comparable amount'') 
rather than a LTCH PPS payment based on the proposed standard Federal 
rate. Therefore, because over 30 percent of all LTCH PPS cases would 
receive a payment that is not based fully on the proposed standard 
Federal rate, the percent change in estimated payments per discharge 
due to the proposed changes to the standard Federal rate for most 
categories of LTCHs shown in Table 9 is projected to be 2.2 percent, 
which is somewhat less than the 2.6 percent proposed update to the 
standard Federal rate. In addition to the proposed 2.6 percent increase 
to the standard Federal rate for RY 2009, the projected percent 
increase in estimated payments per discharge from the 2008 LTCH PPS 
rate year to the 2009 LTCH PPS rate year of 2.9 percent shown in Table 
9 (see column 8) reflects the effect of increased HCO and SSO payments 
as we discussed previously. That is, in calculating the estimated 
increase in payments for HCO and SSO from RY 2008 to RY 2009, we 
increased costs by applying the proposed market basket (approximately 
3.5 percent). As noted above, SSOs comprise approximately 16 percent of 
total LTCH PPS payments and high cost outliers comprise approximately 8 
percent of estimated total LTCH PPS payments. Furthermore, as discussed 
previously in this regulatory impact analysis, the average increase in 
estimated payments per discharge from the 2008 LTCH PPS rate year to 
the 2009 LTCH PPS rate year, on average, for all LTCHs of approximately 
2.9 (as shown in Table 9) was determined by comparing estimated RY 2009 
LTCH PPS payments (using the proposed rates and policies discussed in 
the preamble of this rule) to estimated RY 2008 LTCH PPS payments (as 
described above in section XVI.B.3. of this regulatory impact 
analysis).
a. Location
    Based on the most recent available data, the majority of LTCHs are 
in urban areas. Approximately 6 percent of the LTCHs are identified as 
being located in a rural area, and approximately 5 percent of all LTCH 
cases are treated in these rural hospitals. The impact analysis 
presented in Table 9 shows that the average percent increase in 
estimated payments per discharge for the 2008 LTCH PPS rate year 
compared to the 2009 LTCH PPS rate year for all hospitals is 2.9 
percent for all proposed changes. For rural LTCHs, the percent change 
for all proposed changes is estimated to be 2.6 percent, while for 
urban LTCHs, we estimate this increase to be 2.9 percent. Large urban 
LTCHs are projected to experience a 3.0 percent increase in estimated 
payments per discharge from the 2008 LTCH PPS rate year compared to the 
2009 LTCH PPS rate year, while other urban LTCHs are projected to 
experience a 2.7 percent increase in estimated payments per discharge 
from the 2008 LTCH PPS rate year compared to the 2009 LTCH PPS rate 
year, as shown in Table 9. Rural LTCHs are projected to experience a 
somewhat lower than average increase in estimated payments per 
discharge for all proposed changes primarily due to the proposed 
changes to the area wage adjustment. That is, 68 percent of the LTCHs 
in these areas are expected to experience a decrease in their wage 
index value from RY 2008 to RY 2009. In addition, because all LTCHs in 
rural areas have a wage index value that is less than 1.0, the proposed 
increase to the labor-related share (from 75.788 percent to 75.920 
percent) would also contribute to the estimated lower than average 
increase in estimated payments from RY 2008 to RY 2009 shown in column 
8 of Table 9.
b. Participation Date
    LTCHs are grouped by participation date into four categories: (1) 
Before October 1983; (2) between October 1983 and September 1993; (3) 
between October 1993 and September 2002; and (4) after October 2002. 
Based on the most recent available data, the majority (approximately 52 
percent) of the LTCH cases are in hospitals that began

[[Page 5382]]

participating between October 1993 and September 2002, and are 
projected to experience a slightly lower than average increase of 2.7 
percent in estimated payments per discharge from the 2008 LTCH PPS rate 
year compared to the 2009 LTCH PPS rate year, as shown in Table 9, 
mostly because approximately 66 percent of hospitals in this category 
are projected to experience a decrease in their wage index value from 
RY 2008 to RY 2009. In addition, because the majority of hospitals (80 
percent) in this category have a wage index of less than 1.0, the 
proposed increase to the labor-related share (from 75.788 percent to 
75.920 percent) would also contribute to the slightly lower than 
average increase in payments from RY 2008 to RY 2009 shown in column 8 
of Table 9.
    LTCHs that began participating in Medicare between October 1983 and 
September 1993, and those LTCHs that began participating in Medicare 
after October 2002 are projected to experience close to the average 
percent increase (3.0 percent) in estimated payments per discharge from 
the 2008 LTCH PPS rate year compared to the 2009 LTCH PPS rate year, as 
shown in Table 9. Approximately 12 percent of LTCHs began participating 
in Medicare between October 1983 and September 1993 while approximately 
28 percent of LTCHs began participating in Medicare after October 2002 
(that is, the beginning of the LTCH PPS, which was implemented for cost 
reporting periods beginning on or after October 1, 2002).
    LTCHs that began participating before October 1983 are projected to 
experience a 3.5 percent increase in estimated payments per discharge 
from the 2008 LTCH PPS rate year compared to the 2009 LTCH PPS rate 
year (see Table 9). We are projecting that LTCHs that began 
participating in Medicare before October 1983 would experience a larger 
than average increase in estimated payments for RY 2009 as compared to 
RY 2008 primarily due to the proposed changes to the area wage 
adjustment. This is because approximately 68 percent of the LTCHs that 
began participating in Medicare before October 1983 are located in 
areas where the proposed RY 2009 wage index value would be greater than 
the RY 2008 wage index value. In addition, because a significant number 
(75 percent) of hospitals in this category have a wage index of greater 
than 1.0, the proposed increase to the labor-related share (from 75.788 
percent to 75.920 percent) would also contribute to the larger than 
average increase in estimated payments from RY 2008 to RY 2009.
c. Ownership Control
    Other than LTCHs whose ownership control type is unknown, LTCHs are 
grouped into three categories based on ownership control type: 
Voluntary; proprietary; and government. Based on the most recent 
available data, approximately 6 percent of LTCHs are identified as 
government-owned and operated (see Table 9). We expect that for these 
government-owned and operated LTCHs, estimated 2009 LTCH PPS rate year 
payments per discharge would increase 3.4 percent in comparison to the 
2008 LTCH PPS rate year, as shown in Table 9. We are projecting that 
government-run LTCHs would experience a somewhat higher than average 
increase in estimated payments in RY 2009 as compared to RY 2008 
primarily due to the effect of the proposed changes to the area wage 
adjustment. Specifically, LTCHs in this category are projected to 
experience a higher than average increase in their estimated payments 
from RY 2008 to RY 2009 due to the proposed changes to the area wage 
adjustment primarily because the majority (60 percent) of hospitals in 
this category would experience an increase in their wage index value 
from RY 2008 to RY 2009.
    We project that estimated 2009 LTCH PPS rate year payments per 
discharge for voluntary LTCHs, which account for approximately 22 
percent of LTCHs, would increase near the average (3.1 percent) in 
comparison to estimated 2008 LTCH PPS rate year payments (see Table 9).
    The majority (approximately 67 percent) of LTCHs are identified as 
proprietary. We project that 2009 LTCH PPS rate year estimated payments 
per discharge for these proprietary LTCHs would increase 2.8 percent 
(nearly average) in comparison to the 2008 LTCH PPS rate year (see 
Table 9).
d. Census Region
    Estimated payments per discharge for the 2009 LTCH PPS rate year 
are projected to increase for LTCHs located in all regions in 
comparison to the 2008 LTCH PPS rate year. The percent increase in 
estimated payments per discharge from the 2008 LTCH PPS rate year to 
the 2009 LTCH PPS rate year for all regions is largely attributable to 
the proposed increase in the standard Federal rate.
    Of the 9 census regions, we project that the increase in proposed 
2009 LTCH PPS rate year estimated payments per discharge in comparison 
to the 2008 LTCH PPS rate year would have the largest impact on LTCHs 
in the New England and Pacific regions (3.8 percent and 3.7 percent, 
respectively; see Table 9). LTCHs located in both the New England and 
Pacific regions are expected to experience a larger than average 
increase in estimated payments due to the proposed changes in the area 
wage adjustment (0.7 percent for the New England region, and 0.6 
percent for the Pacific region, as shown in Table 9). This is because 
approximately 85 percent of LTCHs located in the New England region and 
all of the LTCHs in the Pacific region are projected to experience an 
increase in their wage index values for proposed RY 2009 as compared to 
RY 2008.
    We project that in comparison to the 2008 LTCH PPS rate year, the 
proposed 2009 LTCH PPS rate year estimated payments per discharge for 
LTCHs in the East North Central region would increase by approximately 
2.8 percent (nearly average). For LTCHs located in the South Atlantic 
and West North Central regions, we estimate that the slightly higher 
than average projected increase (3.1 percent for each region) in 
estimated payments per discharge for the 2009 LTCH PPS rate year 
compared to the 2008 LTCH PPS rate year is largely a result of the 
proposed changes to the area wage adjustment. That is, we estimate that 
approximately 58 percent of hospitals in the South Atlantic region and 
approximately 55 percent of hospitals in the West North Central region 
would experience an increase in their wage index values from RY 2008 to 
RY 2009. For LTCHs located in the Middle Atlantic, East South Central 
and West South Central regions, we estimate that the somewhat lower 
than average projected increase (2.4 percent, 2.5 percent, and 2.6 
percent, respectively) in estimated payments per discharge for the 2009 
LTCH PPS rate year compared to the 2008 LTCH PPS rate year is largely a 
result of the proposed changes to the area wage adjustment. 
Specifically, nearly all LTCHs in the Middle Atlantic region 
(approximately 89 percent) and the majority of the hospitals in the 
East South Central region (approximately 67 percent) and West South 
Central region (approximately 75 percent) would experience a decrease 
in their wage index value from RY 2008 to RY 2009. Furthermore, because 
a significant number of hospitals in these categories have a wage index 
of less than 1.0, the proposed increase to the labor-related share 
(from 75.788 percent to 75.920 percent) would also contribute to the 
lower than average estimated increase in payments from RY 2008 to RY 
2009.

[[Page 5383]]

e. Bed Size
    LTCHs were grouped into seven categories based on bed size: 0-24 
beds; 25-49 beds; 50-74 beds; 75-124 beds; 125-199 beds; greater than 
200 beds; and unknown bed size.
    We are projecting an increase in estimated 2009 LTCH PPS rate year 
payments per discharge in comparison to the 2008 LTCH PPS rate year for 
all bed size categories. Most LTCHs are in bed size categories where 
estimated 2009 LTCH PPS rate year payments per discharge are projected 
to increase at or near the average increase of 2.9 percent for all 
LTCHs, in comparison to the 2008 LTCH PPS rate year (that is, all LTCH 
bed size categories except the category of LTCHs with 0-24 beds). 
Specifically, estimated payments per discharge for the 2009 LTCH PPS 
rate year are projected to increase for LTCHs with 25-49 and 50-74 beds 
at 2.8 percent, for LTCHs with 75-124 beds at 3.1 percent, for LTCHs 
with 125-199 beds at 2.9 percent, and for LTCHs with more than 200 
beds, at 3.0 percent.
    Estimated payments per discharge for the 2009 LTCH PPS rate year 
for LTCHs with 0-24 beds are projected to have a somewhat lower than 
average increase in comparison to all hospitals (2.6 percent; see Table 
9). This lower than average increase in estimated payments per 
discharge for LTCHs with 0-24 beds is largely due to the proposed 
changes to the area wage adjustment. Specifically, LTCHs in this 
category are expected to experience a larger than average decrease in 
their payments from RY 2008 to RY 2009 due to the proposed changes to 
the area wage adjustment primarily because approximately 73 percent of 
the hospitals in this category are projected to experience a decrease 
in their wage index value from RY 2008 to RY 2009. In addition, because 
the majority (approximately 91 percent) of hospitals in this category 
have a wage index of less than 1.0, the proposed increase to the labor-
related share (from 75.788 percent to 75.920 percent) would also 
contribute to the smaller than average increase in estimated payments 
from RY 2008 to RY 2009 shown in Table 9.
5. Effect on the Medicare Program
    Based on actuarial projections, an estimate of Medicare spending 
(total estimated Medicare program payments) for LTCH services over the 
next 5 years based on current LTCH PPS policy (as established in 
previous LTCH PPS final rules) is shown in Table 4 in section IV.D. of 
the preamble of this proposed rule. As noted previously, we project 
that the provisions of this proposed rule would result in an increase 
in estimated aggregate LTCH PPS payments in RY 2009 of approximately 
124 million (or about 2.9 percent) for the 394 LTCHs in our database.
    Consistent with the statutory requirement for BN, as we discussed 
in the August 30, 2002 final rule that implemented the LTCH PPS, in 
developing the LTCH PPS, we intended estimated aggregate payments under 
the LTCH PPS in FY 2003 be projected to equal the estimated aggregate 
payments that would have been made if the LTCH PPS were not 
implemented. Our methodology for estimating payments for purposes of 
the BN calculations for determining the FY 2003 standard Federal rate 
used the best available data and necessarily reflects assumptions. As 
discussed in section IV.D. of this proposed rule, section 114(c)(4) of 
the Medicare, Medicaid and SCHIP Extension Act of 2007 provides that 
the ``Secretary shall not, for the 3-year period beginning on the date 
of the enactment of this Act, make the one-time prospective adjustment 
to long-term care hospital prospective payment rates provided for in 
section 412.523(d)(3) of title 42, Code of Federal Regulations, or any 
similar provision.'' That provision delays the effective date of any 
one-time budget neutrality adjustment until no earlier than December 
29, 2010. However, prior to the enactment of the MMSEA of 2007, we had 
developed a methodology for evaluating the appropriateness of proposing 
a one-time budget neutrality adjustment under existing Sec.  
412.523(d)(3). In order to inform the public of our thinking, and to 
stimulate comments for our consideration during the three-year delay in 
implementing any adjustment under the recent legislation, we have 
presented our analysis and its results in section IV.D. of the preamble 
of this proposed rule.
6. Effect on Medicare Beneficiaries
    Under the LTCH PPS, hospitals receive payment based on the average 
resources consumed by patients for each diagnosis. We do not expect any 
changes in the quality of care or access to services for Medicare 
beneficiaries under the LTCH PPS, but we expect that paying 
prospectively for LTCH services would enhance the efficiency of the 
Medicare program.

D. Accounting Statement

    As discussed in section XVI.A.1., the impact analysis of this 
proposed rule results in an increase in estimated aggregate payments of 
approximately $124 million (or about 2.9 percent) for the 394 LTCHs in 
our database. Therefore, as required by OMB Circular A-4 (available at 
http://www.whitehouse.gov/omb/circulars/a004/a-4.pdf), in Table 10, we 
have prepared an accounting statement showing the classification of the 
expenditures associated with the provisions of this proposed rule. 
Table 10 provides our best estimate of the proposed increase in 
Medicare payments under the LTCH PPS as a result of the provisions 
presented in this proposed rule based on the data for the 394 LTCHs in 
our database. All expenditures are classified as transfers to Medicare 
providers (that is, LTCHs).

    C. Revising paragraph (d)(3).
    The addition and revisions read as follows:


Sec.  412.523  Methodology for calculating the Federal prospective 
payment rates.

* * * * *
    (c) * * *
    (3) * * *
    (v) For long-term care hospital prospective payment system rate

Federal rate for long-term care hospital prospective payment system 
rate year beginning July 1, 2008 and ending September 30, 2009 is the 
standard Federal rate for the previous long-term care hospital 
prospective payment system rate year updated by 2.6 percent. The 
standard Federal rate is adjusted, as appropriate, as described in 
paragraph (d) of this section.
* * * * *
    (d)(3) The Secretary reviews payments under this prospective 
payment system and may make a one-time prospective adjustment to the 
long-term care hospital prospective payment system rates no earlier 
than December 29, 2010, so that the effect of any significant

follows:


Sec.  412.525  Adjustments to the Federal prospective payment.

* * * * *
    (c) Adjustments for area levels. The labor portion of a long-term 
care hospital's Federal prospective payment is adjusted to account for 
geographical differences in the area wage levels using an appropriate 
wage index (established by CMS), which reflects the relative level of 
hospital wages and wage-related costs in the geographic area (that is, 
urban or rural area as determined in accordance with the definitions 
set forth in Sec.  412.503) of the hospital compared to the national 
average level of hospital wages and wage-related costs. The appropriate 
wage index (established by CMS) is updated annually.
    5. Section 412.529 is amended by revising paragraphs (d)(4)(ii)(B) 
and (d)(4)(iii)(B) to read as follows:


Sec.  412.529  Special payment provision for short-stay outliers.

    (4) * * *
    (ii) * * *
    (B) Is adjusted for different area wage levels based on the 
geographic classifications set forth at Sec.  412.503 and the 
applicable hospital inpatient prospective payment system labor-related 
share, using the applicable hospital inpatient prospective payment 
system wage index value for nonreclassified hospitals. For LTCHs 
located in Alaska and Hawaii, this amount is also adjusted by the 
applicable hospital inpatient prospective payment system cost of living 
adjustment factors.
* * * * *
    (iii) * * *
    (B) Is adjusted for the applicable geographic adjustment factors, 
including local cost variation based on the geographic classifications 
set forth at Sec.  412.503 and the applicable full hospital inpatient 
prospective payment system wage index value for nonreclassified 
hospitals, and applicable large urban location cost of living 
adjustment factors for LTCHs in Alaska and Hawaii, if applicable.
* * * * *
    6. Section 412.534 is amended by revising paragraphs (d)(1), 
(f)(2)(ii), and (f)(3)(ii) to read as follows:


Sec.  412.534  Special payment provisions for long-term care hospitals 
within hospitals and satellites of long-term care hospitals.

* * * * *
    (d) * * *
    (1) Subject to paragraphs (g) and (h) of this section, in the case 
of a long-term care hospital or satellite facility that is located in a 
rural area as defined in Sec.  412.503 and is co-located with another

\1\ Transition blended relative weights for FY 2008 determined as described in Step 7 in section II.I.4. of the
  preamble of the FY 2008 IPPS final rule (72 FR 47295).
\2\ The ``short-stay outlier threshold'' is calculated as 5/6ths of the geometric average length of stay of the
  LTC-DRG (as specified at Sec.   412.529(a), in conjunction with Sec.   412.503).
\3\ The ``IPPS-comparable threshold'' is calculated as one standard deviation from the geometric average length
  of stay of the same DRG under the IPPS as specified at Sec.   412.529(c)(3)(i).
