                                OVERVIEW

    Medicare is a nationwide health insurance program for the 
aged and certain disabled persons. The program consists of two 
parts--part A, hospital insurance (HI) and part B, 
supplementary medical insurance (SMI). Total program outlays 
were $212.0 billion in fiscal year 1999. Net outlays after 
deduction of beneficiary premiums were $190.5 billion.

                                Coverage

    Almost all persons over age 65 are automatically entitled 
to Medicare part A. Part A also provides coverage, after a 24-
month waiting period, for persons under age 65 who are 
receiving Social Security cash benefits on the basis of 
disability. Most persons who need a kidney transplant or renal 
dialysis may also be covered, regardless of age. In fiscal year 
1999, part A covered an estimated 38.8 million aged and 
disabled persons (including those with chronic kidney disease).
    Medicare part B is voluntary. All persons over age 65 and 
all persons enrolled in part A may enroll in part B by paying a 
monthly premium--$45.50 in 2000. In fiscal year 1999, part B 
covered an estimated 36.9 million aged and disabled persons.

                                Benefits

    Part A provides coverage for inpatient hospital services, 
up to 100 days of posthospital skilled nursing facility (SNF) 
care, some home health services, and hospice care. Patients 
must pay a deductible ($776 in 2000) each time their hospital 
admission begins a benefit period. (A benefit period begins 
when a patient enters a hospital and ends when she has not been 
in a hospital or SNF for 60 days.) Medicare pays the remaining 
costs for the first 60 days of hospital care. The limited 
number of beneficiaries requiring care beyond 60 days are 
subject to additional charges. Patients requiring SNF care are 
subject to a daily coinsurance charge for days 21-100 ($97 in 
2000). There are no cost-sharing charges for home health care 
and limited charges for hospice care.
    Part B provides coverage for physicians' services, 
laboratory services, durable medical equipment (DME), hospital 
outpatient department (OPD) services, and other medical 
services. The program generally pays 80 percent of Medicare's 
fee schedule or other approved amount after the beneficiary has 
met the annual $100 deductible. The beneficiary is liable for 
the remaining 20 percent.

                         Payments for Services

    Taken together, spending for inpatient hospital and 
physicians' and related services accounts for close to 70 
percent of Medicare fee-for-service payments (spending for 
managed care plans is not broken down by service category). 
Medicare makes payments for inpatient hospital services under a 
prospective payment system (PPS); a predetermined rate is paid 
for each inpatient stay based on the patient's admitting 
diagnosis. Payment for physicians' services is made on the 
basis of a fee schedule. Specific payment rules are also used 
for other services.

                             Administration

    Medicare is administered by the Health Care Financing 
Administration (HCFA) within the U.S. Department of Health and 
Human Services (DHHS). Much of the day-to-day work of reviewing 
claims and making payments is done by intermediaries (for part 
A) and carriers (for part B). These are generally commercial 
insurers or Blue Cross Blue Shield plans.

                               Financing

    Medicare part A is financed primarily through the HI 
payroll tax levied on current workers and their employers. 
Employers and employees each pay a tax of 1.45 percent on all 
earnings. The self-employed pay a single tax of 2.9 percent on 
earnings.
    Part B is financed through a combination of monthly 
premiums levied on program beneficiaries and Federal general 
revenues. In 2000, the premium is $45.50. Beneficiary premiums 
have generally represented about 25 percent of part B costs; 
Federal general revenues (i.e., tax dollars) account for the 
remaining 75 percent.

                            Federal Outlays

    Total program outlays were $212.0 billion in fiscal year 
1999. Net outlays (i.e., net of premiums beneficiaries pay for 
enrollment, largely for part B) were $190.5 billion.
    Tables 2-1, 2-2, and 2-3 provide historical spending and 
coverage data for Medicare. Table 2-4 provides State-by-State 
information for fiscal year 1998.

                        ELIGIBILITY AND COVERAGE

                                  Aged

Part A
    Most Americans age 65 or older are automatically entitled 
to protection under part A. These individuals (or their 
spouses) established entitlement during their working careers 
by paying the HI payroll tax on earnings covered by either the 
Social Security or Railroad Retirement Systems.
    The HI tax was extended to Federal employment with respect 
to wages paid on or after January 1, 1983. Beginning January 1, 
1983, Federal employment is included in determining eligibility 
for protection under Medicare part A. A transitional provision 
allows individuals who were in the employ of the Federal 
Government both before and during January 1, 1983, to have 
their prior Federal employment considered as employment for 
purposes of providing Medicare coverage. Employees of State and 
local governments, hired after March 31, 1986, are also liable 
for the HI tax.
    Persons age 65 or older who are not automatically entitled 
to part A may obtain coverage, providing they pay the full 
actuarial cost. The 2000 monthly premium is $301 ($166 for 
persons who have at least 30 quarters of covered employment).

Part B
    Part B of Medicare is voluntary. All persons age 65 or 
older (even those not entitled to part A) may elect to enroll 
in the SMI Program by paying the monthly premium. The 2000 
premium is $45.50 per month. Persons who voluntarily enroll in 
part A are required to enroll in part B.

                                Disabled

Part A
    Part A also covers, after a 2-year waiting period, people 
under age 65 who are either receiving monthly Social Security 
benefits on the basis of disability or receiving payments as 
disabled Railroad Retirement System annuitants. (Dependents of 
the disabled are not eligible.) In addition, most people who 
need a kidney transplant or renal dialysis because of chronic 
kidney disease are entitled to benefits under part A regardless 
of age.
Part B
    Persons eligible for part A by virtue of disability or 
chronic kidney disease may also elect to enroll in part B.

                        Number of Beneficiaries

    In fiscal year 1998, 33.4 million aged and 5.1 million 
disabled had protection under part A. In fiscal year 1998, 32.3 
million aged and 4.4 million disabled were enrolled in part B 
(table 2-2).

                 BENEFITS AND BENEFICIARY COST SHARING

                                 Part A

    Part A coverage includes:
    Inpatient hospital care.--The first 60 days of inpatient 
hospital services in a benefit period are subject to a 
deductible ($776 in calendar year 2000). A benefit period 
begins when a patient enters a hospital and ends when he has 
not been in a hospital or SNF for 60 days. For days 61-90 in a 
benefit period, a coinsurance amount ($194 in calendar year 
2000) is imposed. When more than 90 days are required in a 
benefit period, a patient may elect to draw upon a 60-day 
lifetime reserve. A coinsurance amount ($388 in calendar year 
2000) is imposed for each reserve day.
    Skilled nursing facility care.--SNF care is up to 100 days 
(following hospitalization) in an SNF for persons in need of 
continued skilled nursing care and/or skilled rehabilitation 
services on a daily basis. After the first 20 days, there is a 
daily coinsurance ($97 in calendar year 2000) amount.
    Home health care.--Home health visits are provided to 
persons who need skilled nursing care on an intermittent basis, 
or physical therapy, or speech therapy. The Balanced Budget Act 
(BBA) of 1997 gradually transfers from part A to part B home 
health visits that are not part of the first 100 visits 
following a beneficiary's stay in a hospital or SNF (i.e., 
postinstitutional visits) and during a home health spell of 
illness. The transfer is being phased in over 6 years, between 
1998 and 2003, with the Secretary transferring one-sixth of the 
aggregate expenditures associated with transferred

visits in 1998; two-sixths in 1999; three-sixths in 2000; four-
sixths in 2001; five-sixths in 2002; and six-sixths in 2003. 
Beginning January 1, 2003, part A will cover only 
postinstitutional home health services for up to 100 visits 
during a home health spell of illness, except for those persons 
with part A coverage only, who will be covered for services 
without regard to the postinstitutional limitation.
    Hospice care.--Hospice care services are provided to 
terminally ill Medicare beneficiaries with a life expectancy of 
6 months or less for two 90-day periods, followed by an 
unlimited number of 60-day periods. The medical director or 
physician member of the hospice interdisciplinary team must 
recertify, at the beginning of 60-day periods, that the 
beneficiary is terminally ill.

                                 Part B

    Part B of Medicare generally pays 80 percent of the 
approved amount (fee schedule, reasonable charge, or reasonable 
cost) for covered services in excess of an annual deductible 
($100). Services covered include:
    Doctor's services.--This category includes surgery, 
consultation, and home, office and institutional visits. 
Certain limitations apply for services rendered by dentists, 
podiatrists, and chiropractors and for the treatment of mental 
illness.
    Other medical and health services.--This category includes 
laboratory and other diagnostic tests, x ray and other 
radiation therapy, outpatient hospital services, rural health 
clinic services, DME, home dialysis supplies and equipment, 
artificial devices (other than dental), physical and speech 
therapy, and ambulance services.
    Specified preventive services.--These services include: an 
annual screening mammography for all women over age 40; a 
screening Pap smear and a screening pelvic exam once every 3 
years, except for women who are at a high risk of developing 
cervical cancer; specified colorectal screening procedures; 
diabetes self-management training services; bone mass 
measurements for high-risk persons; and prostate cancer 
screenings.
    Drugs and vaccines.--Generally Medicare does not pay for 
outpatient prescription drugs or biologicals. Part B pays for 
immunosuppressive drugs for a minimum of 36 months following a 
covered organ transplant, erythropoietin (EPO) for treatment of 
anemia for persons with chronic kidney failure, and certain 
oral cancer drugs. The program also covers flu shots, 
pneumococcal pneumonia vaccines, and hepatitis B vaccines for 
those at risk.
    Home health services.--Home services include an unlimited 
number of medically necessary home health visits for persons 
not covered under part A. The 20-percent coinsurance and $100 
deductible do not apply for such benefits. As noted above, BBA 
1997 gradually transfers some home health costs from part A to 
part B, beginning in 1998.
    Table 2-5 illustrates the deductible, coinsurance and 
premium amounts for both part A and part B services from the 
inception of Medicare.

                               FINANCING

    The Medicare Hospital Insurance (HI) Trust Fund finances 
services covered under Medicare part A. The Supplementary 
Medical Insurance (SMI) Trust Fund finances services covered 
under Medicare part B. The trust funds are maintained by the 
Department of the Treasury. Each trust fund is actually an 
accounting mechanism; there is no actual transfer of money into 
and out of the fund. Income to each trust fund is credited to 
the fund in the form of interest-bearing government securities. 
The securities represent obligations that the government has 
issued to itself. Expenditures for services and administrative 
costs are recorded against the fund.

                 Hospital Insurance Trust Fund--Income

    The primary source of income to the HI fund is HI payroll 
taxes. This source accounted for $134.4 billion (87.8 percent) 
of the total $153.0 billion in income for fiscal year 1999. 
Additional income sources include premiums paid by voluntary 
enrollees, government credits, interest on Federal securities, 
and taxation of a portion of Social Security benefits.
Payroll taxes
    The HI Trust Fund is financed primarily through Social 
Security payroll tax contributions paid by employees and 
employers. Each pays a tax of 1.45 percent on all earnings in 
covered employment. The self-employed pay 2.9 percent. Prior to 
1994, there was an upper limit on earnings subject to the tax. 
An upper limit of $76,200 in 2000 continues to apply under 
Social Security. Table 2-6 shows the history of the 
contribution rates and maximum taxable earnings base for the HI 
Program.
Other income
    The following are additional sources of income to the HI 
fund:
 1. Railroad retirement account transfers.--In fiscal year 
        1999, $430 million was transferred from the railroad 
        retirement fund. This is the estimated amount that 
        would have been in the fund if railroad employment had 
        always been covered under the Social Security Act.
 2. Reimbursements for uninsured persons.--HI benefits are 
        provided to certain uninsured persons who turned 65 
        before 1968. Persons who turned 65 after 1967 but 
        before 1974 are covered under transitional provisions. 
        Similar transitional entitlement applies to Federal 
        employees who retire before earning sufficient quarters 
        of Medicare-qualified Federal employment provided they 
        were employed before and during January 1983. Payments 
        for these persons are made initially from the HI Trust 
        Fund, with reimbursement from the general fund of the 
        Treasury for the costs, including administrative 
        expenses, of the payments. In fiscal year 1999, $652 
        million was transferred to HI on this basis.

\1\ For services furnished on or after January 1, 1982, the coinsurance amounts are based on the inpatient hospital deductible for the year in which the
  services were furnished. For services furnished prior to January 1, 1982, the coinsurance amounts are based on the inpatient hospital deductible
  applicable for the year in which the individual's benefit period began.
\2\ For care in psychiatric hospital there is a 190-day lifetime limit.

  benefits per year, July 1, 1966 through December 31, 1987; $450 in benefits per year, January 1, 1988 through December 31, 1988; $1,100 in benefits
  per year, January 1, 1989 through December 31, 1989; beginning January 1, 1990, the limit was removed; (2) physical and occupational therapy services
  furnished by physical therapists in independent practice: maximum annual approved charges July 1, 1973 through December 31, 1981, $80 per year;
  January 1, 1982 through December 31, 1982, $400 per year; January 1, 1983 through December 31, 1989, $500 per year; January 1, 1990 through December
  31, 1993, $750 per year; and January 1, 1994 through December 31, 1998; in 1999 there was an annual $1,500 limit on all physical therapy services
  (except those provided by a hospital) and an annual $1,500 limit on all occupational therapy services (except those provided by a hospital); and no
  limit in 2000.

\1\ Prior to 1991, the upper limit on tax earnings was the same as for Social Security. The Omnibus Budget
  Reconciliation Act of 1990 raised the limit in 1991 to $125,000. Under automatic indexing provisions, the
  maximum was increased to $130,200 in 1992 and $135,000 in 1993.
\2\ The Omnibus Budget Reconciliation Act of 1993 eliminated the ceiling on the earnings base beginning in 1994.

 3. Premiums from voluntary enrollees.--Certain persons not 
        eligible for HI protection either on an insured basis 
        or on the uninsured basis described above may obtain 
        protection by enrolling in the program and paying a 
        monthly premium ($309 in 2000; for persons who have at 
        least 30 quarters of covered employment, $170 in 2000). 
        This accounted for an estimated $1.4 billion of 
        financing in fiscal year 1999.
 4. Payments for military wage credits.--Sections 217(g) and 
        229(b) of the Social Security Act, prior to 
        modification by the Social Security Amendments of 1983, 
        authorized annual reimbursement from the general fund 
        of the Treasury to the HI Trust Fund for costs arising 
        from the granting of deemed wage credits for military 
        service prior to 1957, according to quinquennial 
        determinations made by the Secretary of the U.S. 
        Department of Health and Human Services (DHHS). These 
        sections, as modified by the Social Security Amendments 
        of 1983, provided for a lump-sum transfer in 1983 for 
        costs arising from such wage credits. In addition, the 
        lump-sum transfer included combined employer-employee 
        HI taxes on the noncontributory wage credits for 
        military service after 1965 and before 1984. After 
        1983, HI taxes on military wage credits are credited to 
        the fund on July 1 of each year. The Social Security 
        Amendments of 1983 also provided for: (1) quinquennial 
        adjustments to the lump-sum amount transferred in 1983 
        for costs arising from pre-1957 deemed wage credits; 
        and (2) adjustments as deemed necessary to any 
        previously transferred amounts representing HI taxes on 
        noncontributory wage credits. In fiscal year 1999, this 
        adjustment was $67 million.
 5. Tax on Social Security benefits.--Beginning in 1994, the 
        trust fund acquired an additional funding source. The 
        Omnibus Budget Reconciliation Act of 1993 (OBRA 1993) 
        increased the maximum amount of Social Security 
        benefits subject to income tax from 50 to 85 percent 
        and provided that the additional revenues would be 
        credited to the HI Trust Fund. Revenue from this source 
        totaled $6.6 billion in fiscal year 1999.
 6. Interest.--The remaining income to the trust fund consists 
        almost entirely of interest on the investments of the 
        trust fund. Interest amounted to an estimated $9.5 
        billion in fiscal year 1999.

           Supplementary Medical Insurance Trust Fund--Income

    Part B is financed from premiums paid by the aged, disabled 
and chronic renal disease enrollees and from general revenues. 
The premium rate is derived annually based on the projected 
costs of the program for the coming year. The monthly premium 
amount in calendar year 2000 is $45.50.
    When the program first went into effect in July 1966, the 
part B monthly premium was set at a level to finance one-half 
of part B program costs. Legislation enacted in 1972 limited 
the annual percentage increase in the premium to the same 
percentage by which Social Security benefits were adjusted for 
changes in cost of living (i.e., cost-of-living adjustments). 
Under this formula, revenues from premiums soon dropped from 50 
to below 25 percent of program costs because part B program 
costs increased much faster than inflation as measured by the 
Consumer Price Index (CPI) on which the Social Security cost-
of-living adjustment is based.
    Beginning in the early 1980s, Congress regularly voted to 
set part B premiums at a level to cover 25 percent of program 
costs, in effect overriding the cost-of-living adjustment 
limitation. The 25-percent provisions first became effective 
January 1, 1984. General revenues covered the remaining 75 
percent of part B program costs. BBA 1997 permanently sets the 
part B premium equal to 25 percent of program costs.

    Each year, the HI Trustees make projections for the date

report stated that under the Trustees intermediate assumptions, 
the fund would become insolvent in 2001. Subsequent reports 
significantly delayed the projected insolvency date. The 2000

ments can be attributed to a number of factors including 
improvements in the economy as a whole (which are reflected in 
higher payroll tax revenues) and a lower rate of growth in 
program expenditures. A key factor was the enactment of BBA 
1997. This legislation provided for the transfer of a portion 
of home health spending (which at the time was the fastest 
growing component of part A expenditures) from part A to part 
B. It also included additional provisions to stem the growth in 
part A expenditures. These provisions included the 
implementation of new payment limits for home health services, 
a prospective payment system (PPS) for skilled nursing facility 
(SNF) services, and limits on the increases in hospital 
payments. BBA 1997 also established the Medicare+Choice (M+C) 
Program and modified the calculation of payments to managed 
care entities.
    Following enactment of BBA 1997, a number of observers 
claimed that the actual savings achieved by BBA 1997 were 
larger than was intended when the legislation was enacted. As a 
result, legislation was enacted in 1999 (Balanced Budget 
Refinement Act (BBRA) of 1999) which mitigated the impact of 
BBA 1997 on providers. Notwithstanding enactment of BBRA 1999, 
the 2000 Trustees' Report (as amended) delays the trust fund 
insolvency date an additional 10 years over that projected in 
the 1999 report (from 2015 to 2025).
    The 2000 report states that the fund meets the Trustees' 
test of short-range financial adequacy for the first time since 
1991. The projected long-range actuarial balance is moderately 
improved, but a substantial long-range deficit remains. The 
Trustees note that future operations will be very sensitive to 
future economic, demographic, and health cost trends and could 
differ substantially from the intermediate projections.
    Beginning in 2011, the program will begin to experience the 
impact of major demographic changes. First, baby boomers 
(persons born between 1946 and 1964) begin turning age 65. 
Second, there will be a shift in the number of covered workers 
supporting each HI enrollee. In 1999, there were 4 workers for 
every beneficiary; in 2030 there will only be an estimated 2.3.

     Financial Status of Supplementary Medical Insurance Trust Fund

    Because the SMI Trust Fund is financed through beneficiary 
premiums and Federal general revenues, it does not face the 
prospect of depletion, as does the HI Trust Fund. However, the 
rising cost of the program is placing a burden on the trust 
fund, and by extension on beneficiaries (in the form of 
premiums) and Federal general revenues. Table 2-10 shows 
historical information from the 2000 Trustees' Report (Board of 
Trustees, Federal Supplementary Medical Insurance Trust Fund, 
2000).

Comparison of Medicare Lifetime Benefits with Beneficiary Contributions

    Medicare beneficiaries typically get back considerably more 
in Medicare benefits than they contribute in payroll taxes and 
premiums over their lifetimes. The Congressional Budget Office

to which Medicare enrollees' contributions (through the HI 
payroll tax and the SMI premium) cover the expected value of 
their benefits under the program. Results are presented only 
for self-insured men and women (i.e., those who obtain benefits 
on the basis of their own work history) who worked each year at 
an average wage from 1966 until retirement at age 65 (table 2-

1995, and 2005. All estimates are dependent on uncertain 
projections of future health spending.

Note.--Contributions include employers' and employees' HI payroll taxes,

  included. Estimates are for beneficiaries with sufficient work history
  to qualify for benefits. However, up to 20 percent of Medicare
  beneficiaries qualify on the basis of their spouse's work history, not
  their own. For spouse-insured beneficiaries, contributions as a
  percent of benefits are lower because spouse-insured beneficiaries
  paid little or no HI payroll taxes. Estimates assume an expected
  lifetime at age 65 of 15 years for men (to age 80) and 19 years for
  women (to age 84). Present discounted values for expected benefits
  were obtained using the average interest rate projected for HI Trust
  Fund earnings over the same years.

    For a self-insured man who worked continuously at an 
average wage from 1966 (when Medicare began) until retirement 
in 1985, the present discounted value of their contributions is 
about 30 percent of the expected value of lifetime Medicare 
benefits. For men retiring in 1995, contributions represent 
about 50 percent of benefits; for those retiring in 2005, 
contributions represent about 69 percent. Contributions through 
HI payroll taxes increase relative to HI benefits for later 
retirees because the HI payroll tax (which began in 1966) was 
paid for a greater proportion of their working years (table 2-
11).
    Contributions by self-insured women as a percentage of 
expected benefits are smaller than they are for men. Actual 
contributions by men and women are the same in the illustrative 
calculations. However, a woman's lifetime benefits are larger 
because a woman's lifetime expectancy is 4 years longer at age 
65 (table 2-11).
    In 1995 dollars, the present discounted value of Medicare 
benefits net of contributions (i.e., the net transfer or 
subsidy value) is estimated at $30,742 for men and $35,623 for 
women who retired in 1985. For those retiring in 1995, the 
value is estimated at $31,429 for men and $39,069 for women. 
CBO projects that values will decline in the future, reaching 
$26,429 for men and $36,354 for women by 2005 (table 2-12).

                 PART A SERVICES--COVERAGE AND PAYMENTS

                      Inpatient Hospital Services

    Medicare part A provides reimbursement for inpatient 
hospital care through the prospective payment system (PPS), 
established by Congress in the Social Security Amendments of 
1983 (Public Law 98-21). Before the enactment of PPS, Medicare 
paid hospitals retrospectively for the full costs they 
incurred, subject to certain limits and tests of 
reasonableness. Congress had previously acted to contain 
growing hospital costs by placing certain limits on routine 
inpatient care operating costs. However, medical costs 
continued to grow faster than the rate of inflation in the 
early 1980s, so PPS was enacted to constrain the growth of 
Medicare's inpatient hospital costs by providing incentives for 
hospitals to provide care more efficiently (see appendix D for 
further information about hospital services).
    Under PPS, fixed hospital payment amounts are established 
in advance of the provision of services on the basis of a 
patient's diagnosis. Hospitals that are able to provide 
services for less than the fixed PPS payment may keep the 
difference. Hospitals with costs that exceed the fixed PPS 
payment lose money on the case. The system's fixed prices are 
determined in advance on a cost-per-case basis, using a 
classification system of about 500 diagnosis-related groups 
(DRGs). Each Medicare case is assigned to one of the DRGs based 
on the patient's medical condition and treatment. DRGs are 
assigned relative weights to reflect the variation in the costs 
of treating a particular diagnosis. The DRG-based payment rate 
is designed to represent the national average cost per case for 
treating a patient with a particular diagnosis. Payments for a 
particular DRG will vary among different hospitals depending on 
the hospital's location and certain other characteristics. In a 
particular hospital, all cases assigned to the same DRG are 
reimbursed at the same predetermined rate.
    The PPS payment rates are updated each year using an update 
factor which is determined, in part, by the projected increase 
in the hospital market basket index (MBI). The hospital MBI 
measures the cost of goods and services that are purchased by 
hospitals, yielding one price inflator for all hospitals in a 
given year.
    In addition to the basic DRG payment for each case, PPS 
hospitals may also receive certain supplemental Medicare 
payments. Additional hospital payments include indirect medical 
education costs, disproportionate share hospital (DSH) 
payments, outlier payments, and payments for inpatient dialysis 
provided to end-stage renal disease (ESRD) beneficiaries. 
Certain categories of hospital expenses, including direct 
medical education costs, are not included in the PPS rates and 
are reimbursed in some other way. Certain facilities receive 
special treatment under PPS, particularly certain types of 
isolated or essential hospitals in rural areas, including 
regional referral centers, sole community hospitals, and 
Medicare-dependent small rural hospitals.
    Specialized facilities are excluded from PPS and are paid 
on the basis of reasonable costs subject to rate of increase 
limits. PPS-exempt facilities include psychiatric hospitals, 
rehabilitation hospitals, children's hospitals, cancer research 
centers, and long-term care hospitals. States are also allowed 
to apply for a waiver from PPS and establish a prospective 
system for setting hospital rates instead of what would be paid 
under PPS; Maryland is the only State that continues to operate 
under such a waiver.

                   Skilled Nursing Facility Services

Coverage
    The Medicare Program covers extended care services provided 
in nursing homes for beneficiaries who require additional 
skilled nursing care and rehabilitation services following a 
hospitalization. These extended care services, commonly known 
as skilled nursing facility (SNF) benefits, are covered under 
part A of the program for up to 100 days per spell of illness 
and must be provided in an SNF certified to participate in 
Medicare. A spell of illness is that period which begins when a 
beneficiary is furnished inpatient hospital or SNF care and 
ends when the beneficiary has been neither an inpatient of a 
hospital nor an SNF for 60 consecutive days. A beneficiary may 
have more than one spell of illness per year.
    In order to be eligible for SNF care, the beneficiary must 
have been an inpatient of a hospital for at least 3 consecutive 
days and must be transferred to an SNF, usually within 30 days 
of discharge from the hospital. Furthermore, a physician must 
certify that the beneficiary is in need of skilled nursing care 
or other skilled rehabilitation services, which, as a practical 
matter, can only be provided on an inpatient basis and which 
are related to the condition for which the beneficiary was 
hospitalized.
    Covered SNF services include the following:
  --Nursing care provided by or under the supervision of a 
        registered nurse;
  --Room and board;
  --Physical or occupational therapy or speech-language 
        pathology;
  --Medical social services;
  --Drugs, biologicals, supplies, appliances, and equipment 
        ordinarily furnished by an SNF for the care of 
        patients;
  --Medical services of interns and residents in training under 
        an approved teaching program of a hospital with which 
        the SNF has a transfer agreement; and
  --Other services necessary to the health of patients that are 
        generally provided by SNFs.
Reimbursement
    Prior to the Balanced Budget Act (BBA) of 1997 Medicare 
reimbursed SNF care on a retrospective cost-based basis. This 
meant that SNFs were paid after services were delivered for the 
reasonable costs (as defined by program) they incurred for the 
care they provided. SNFs had few incentives to maximize 
efficiency and minimize their costs, and little inducement to 
control the amount or number of services they provided.
    Prospective payment system.--In BBA 1997, Congress required 
that a prospective payment system (PPS) for SNF care be phased 
in over 3 years, beginning with the SNF's first cost reporting 
period after July 1, 1998. Prospective payment involves 
grouping patients according to the type and intensity of 
services they require and setting a daily payment rate for each 
payment group before the services are provided. Like other PPSs 
that pay health care providers for care to Medicare 
beneficiaries on the basis of predetermined, fixed amounts, 
Medicare payments to SNFs are intended to pay the provider for 
its Medicare beneficiary costs on average. That is, although 
the payment is a fixed daily rate, a facility's actual costs 
may be above or below that amount for an individual patient. 
The goal for the facility is to incur costs that, on average, 
over time, do not exceed the PPS average amounts.
    Under BBA 1997 provisions, an SNF is paid a daily rate 
(``Federal per-diem rate''), prospectively determined, for all 
covered services provided to beneficiaries while they are 
eligible for SNF benefits. These include all routine, 
ancillary, and capital-related costs. An amount is added to 
this daily rate to cover part B services received by SNF-
eligible patients; some part B services are excluded from this 
``add on''--primarily the services of physicians and certain 
nonphysician practitioners such as physician assistants, nurse 
practitioners, and psychologists, who are paid separately under 
part B.
    The SNF PPS required by BBA 1997 reflects the resource 
utilization group (RUG) design developed by HCFA. It is a 
hierarchical classification system accounting for the type and 
level of care needed by SNF patients and the relative amount of 
resources needed to provide a patient's care. Under the 
original RUG system implemented in 1998, there were seven basic 
categories of care, including, in hierarchical order: (1) 
rehabilitation; (2) extensive services; (3) special care; (4) 
clinically complex; (5) impaired cognition; (6) behavior 
problems; and (7) reduced physical function. These seven 
categories were further broken down into 44 specific patient 
groupings. The system ascribed a per-diem payment amount for 
each of the 44 groupings. These amounts are adjusted by a wage 
index to account for geographic variations in wages among urban 
and rural areas. The rates are updated annually using an SNF 
MBI. HCFA issued a final rule implementing the PPS on July 30, 
1999 (64 Federal Register 41644-701).
    Transition period.--BBA 1997 provided that the Federal per-
diem rate would apply immediately to all SNFs that received 
their first Medicare payment on or after October 1, 1995. For 
those that received their first Medicare payment before that 
date, a 3-year transition period was established. During the 
transition period, the PPS has two components: a Federal PPS 
component under the RUG system and a ``facility-specific'' 
component. This latter is computed separately for each SNF to 
reflect the facility's own average costs under the pre-PPS 
system. Payments for the first cost reporting period beginning 
on or after July 1, 1998, are a blend of 75 percent facility-
specific rate and 25 percent Federal rate. For the second cost 
reporting period, the facility-specific percentage is 50 
percent and the Federal, 50 percent. For the third period, the 
facility-specific percentage is 25 percent and the Federal, 75 
percent. For all subsequent years, payments will be based 
entirely on the Federal per-diem rate.
    Consolidated billing.--Congress also included a 
consolidated billing provision in BBA 1997 to address the 
potential for fraud and duplicate billing for SNF services. 
Under this provision, the SNF is responsible for billing 
Medicare for all services (with certain exceptions) provided to 
its residents under both parts A and B. This provision applies 
to beneficiaries residing in an SNF or in any part of a nursing 
home which contains a Medicare-certified SNF portion. It 
applies both to patients who are in a part A covered stay and 
those who are not. Although the SNF might provide these 
services under arrangements with outside providers, the outside 
provider must get its payment through the SNF rather than by 
billing Medicare directly.
    BBA 1997 excluded some services from the SNF consolidated 
billing requirement, including those provided by physicians and 
certain nonphysician practitioners, and dialysis-related 
services and supplies. Regulations excluded hospice care 
related to a beneficiary's terminal illness and certain 
ambulance trips to and from SNFs. Providers of these services, 
which are covered under part B, bill Medicare directly.
    BBA 1997 established the PPS for SNFs with the purpose of 
slowing the rate of growth in SNF payments under Medicare. In 
January 1998, a few months after enactment of BBA 1997, CBO 
projected that Medicare spending on SNFs for 1998 would remain 
at 1997 levels. However, actual spending in 1998 was much lower 
than anticipated. In March 1999, CBO revised its 1998 estimate 
to indicate a decrease in SNF spending of $900 million. It has 
also revised downward its 5- and 10-year estimates for total 
SNF spending. A number of factors contributed to the reductions 
in Medicare spending for SNFs. These include lower inflation, 
which results in lower payments to providers; and HCFA's 
heightened efforts to combat fraud and abuse, resulting in a 
reduction in incorrect overpayments. However, SNF industry 
spokespersons said that these reductions indicate that changes 
made to Medicare's reimbursement policies were too drastic, 
causing financial problems for SNFs, and that they should be 
reexamined.
    In addition, industry representatives and others (including 
the Medicare Payment Advisory Commission) were concerned that 
the RUG system based on 44 payment categories might not 
adequately cover the costs of treating patients with clinically 
complex problems requiring skilled nursing care (high acuity 
patients), and those needing extensive ancillary nontherapy 
services, such as laboratory tests, drugs and biologicals, 
imaging services, and transportation.
    Balanced Budget Refinement Act (BBRA) of 1999.--In response 
to concerns about the adequacy of payments under the RUG 
system, Congress enacted, in BBRA, temporary increases for 
Medicare payments for 15 of the 44 RUGs. These 20-percent 
increases apply to SNF care furnished to patients categorized 
as needing extensive services, special care, clinically complex 
care, and certain high level and medium level rehabilitation 
services. The special payments are available beginning April 1, 
2000, and ending the later of October 1, 2000, or the date of 
implementation of a refined, revised RUG system.
    BBRA also provided for a 4-percent increase in the Federal 
per-diem rate for SNF services for fiscal year 2001 and fiscal 
year 2002. This increase is not to be considered in the base 
amount used to compute updates to the Federal per-diem rate.
    Other changes made by BBRA include the following items:
 1. SNFs may elect to receive Medicare payments based 100 
        percent on the Federal per-diem rate, rather than under 
        the phase-in schedule, if it would be more advantageous 
        for them to do so.
 2. Starting April 1, 2000, separate payments above the RUG 
        per-diem rate would be made for certain ambulance 
        services for dialysis patients, certain prostheses, and 
        certain chemotherapy drugs for SNF patients.
 3. If at least 60 percent of an SNF's patients are 
        immunocompromised, RUG payments will be based 50 
        percent on the facility specific rate and 50 percent on 
        the Federal per-diem rate (rather than moving to 100 
        percent of the Federal rate) until October 1, 2001.
    CBO estimates that the changes in payments to SNFs made by 
BBRA will increase spending for SNF care by $2.2 billion in the 
first 5 years.
SNF payments and utilization
    For a number of years, SNF care was one of Medicare's 
fastest growing benefits. Tables 2-14 and 2-15 show that SNF 
utilization and spending first began to increase substantially 
in 1988 and 1989. These increases can be traced to changes that 
occurred in the benefit at that time.

    First, HCFA issued new coverage guidelines that became 
effective early in 1988. Prior to this time, studies had 
pointed to a lack of adequate written guidance on coverage 
criteria that led to inconsistencies in coverage decisions for 
a benefit that was intended to be uniform across the country. 
As a result, many SNFs were reluctant to accept Medicare 
beneficiaries because of the possibility that a submitted claim 
would be retroactively denied. The 1988 guidelines clarified 
coverage criteria by providing numerous examples of covered and 
noncovered care. Furthermore, the guidelines explained that 
even when a patient's full or partial recovery is not possible, 
care could be covered if it were needed to prevent 
deterioration or to maintain current capabilities. Previously, 
some care had been denied coverage because patients' health 
status was not expected to improve.
    The second major, though temporary, change in Medicare's 
SNF benefit came in 1988 with the enactment of the Medicare 
Catastrophic Coverage Act (MCCA). Effective beginning in 1989, 
this legislation eliminated the SNF benefit's prior 
hospitalization requirement; revised the coinsurance 
requirement to be equal to 20 percent of the national average 
estimated per-diem cost of SNF services for the first 8 days of 
care; and authorized coverage of up to 150 days of care per 
calendar year (rather than 100 days per spell of illness). 
These changes were repealed in 1989, and the SNF benefit's 
structure assumed its prior form.
    Studies have suggested that the coverage guidelines and 
MCCA changes together might have caused a long-run shift in the 
nursing home industry toward Medicare patients that would not 
end with repeal of MCCA. Table 2-14 shows that SNF spending in 
calendar year 1990 stood at $2.5 billion; by 1997 it had 
increased to $13.0 billion, for an average annual growth rate 
of 27 percent. With implementation of the RUG payment system in 
mid-1998, however, the rate of increase dropped precipitously: 
between 1997 and 1998 the increase was 3.8 percent, and 
payments decreased by 12.6 percent in 1999.
    Table 2-15 shows that between 1992 and 1997 the number of 
Medicare beneficiaries receiving SNF care doubled from 785,000 
to 1.57 million. The number of covered days grew from 29 
million to 50.6 million, or by 74 percent. Payments per day 
grew from $157 in 1992 to $262 in 1997, a 67-percent increase. 
However, in 1998 when the RUG system went into effect, these 
payments increased by only 2.2 percent to $268, and decreased 
to $243 per day in 1999, a 9.3 percent decrease. These 
decreases in payments led to the changes enacted in BBRA 
described above.

                          Home Health Services

Coverage and eligibility
    Medicare home health services are covered under part A of 
the program and, in certain circumstances, under part B. Prior 
to BBA 1997, home health care was paid under part A unless an 
individual was ineligible for part A but had purchased part B 
coverage. In BBA 1997, Congress transferred payment for some 
home health care from part A to part B. The transfer applies to 
home visits beyond the first 100 visits that follow a stay in a 
hospital or an SNF, beginning in 1998, phased in over 6 years. 
No beneficiary deductibles or coinsurance are required for home 
health care.
    To qualify for home health care under Medicare an 
individual must be homebound. A homebound individual is defined 
as one who cannot leave home without a considerable and taxing 
effort and only with the aid of devices such as a wheelchair, a 
walker, or through use of special transportation. Absences from 
home may occur infrequently for short periods of time for such 
purposes as to receive medical treatment.
    Homebound individuals qualify for coverage of home health 
care if they need intermittent skilled nursing care, physical 
therapy, or speech-language pathology services. Beneficiaries 
needing one or more of these ``qualifying services'' may also 
receive occupational therapy, the services of a medical social 
worker, or a home health aide. Occupational therapy can 
continue to be provided after the need for skilled nursing 
care, physical therapy, or speech therapy ends, but social work 
or aide services may not.
    Home health care is covered by Medicare as long as the care 
is medically reasonable and necessary for the treatment of 
illness or injury. Although the number of home health visits a 
beneficiary may receive is unlimited, services must be provided 
pursuant to a plan of care that is prescribed and periodically 
reviewed by a physician. In general, Medicare's home health 
benefit is intended to serve beneficiaries needing acute 
medical care requiring the services of skilled health care 
personnel. It was never envisioned as providing coverage for 
the nonmedical supportive care and personal care assistance 
needed by chronically impaired persons. It is not a long-term 
care program for the disabled or the frail elderly.
    For beneficiaries meeting the qualifying criteria, 
Medicare's home health benefit covers the following services:
 1. Part-time or intermittent nursing care provided by or under 
        the supervision of a registered nurse;
 2. Physical or occupational therapy or speech-language 
        pathology services;
 3. Medical social services;
 4. Part-time or intermittent services of a home health aide 
        who has successfully completed a training program 
        approved by the Secretary;
 5. Medical supplies (excluding drugs and biologicals) and 
        durable medical equipment (DME);
 6. Medical services provided by an intern or resident in 
        training under an approved training program with which 
        the agency may be affiliated; and
 7. Certain other outpatient services which involve the use of 
        equipment that cannot readily be made available in the 
        beneficiary's home.
    Home health services are provided by private or public home 
health agencies (HHAs) that specialize in provision of such 
services and that are certified to participate in Medicare by 
HCFA. HHAs may be public or government-sponsored entities, 
private nonprofit agencies, or proprietary for-profit agencies. 
Hospitals may own or sponsor an HHA. Home health care givers 
may be employees of the HHA or may work for an agency under 
contract. HCFA characterizes a typical HHA as having 486 
Medicare admissions and 30,000 visits per year and an 18 person 
staff. Often, Medicare beneficiaries constitute the great 
majority of an HHA's caseload, although other users include 
individuals covered by Medicaid and those with private 
insurance or who pay out of pocket.
    According to HCFA data, the overall average number of home 
health care visits received by Medicare home health patients in 
1997 was 82, up from 23 in 1987. On average, Medicare 
beneficiaries qualifying for home health care have one episode 
of covered care, and the average number of visits received in 
one episode of coverage is 36.
Background of the Medicare home health benefit
    In the early years of the program, Medicare part A covered 
up to 100 home health visits for beneficiaries who had an 
immediate prior hospitalization or care in an SNF. Home health 
care was also covered under part B, up to 100 visits, for 
beneficiaries who had no prior hospitalization, or who had 
exhausted their 100 part A visits, or who had part B coverage 
only. It was required that a physician determine that the 
individual could be discharged to his or her home but would 
require skilled nursing care on less than a full-time basis, or 
physical therapy, or speech therapy.
    The Omnibus Budget Reconciliation Act of 1980 (Public Law 
96-499) made several liberalizing changes in the rules 
governing Medicare's coverage of home health services, 
including elimination of the requirement for a prior 
hospitalization and removal of the limitation on the number of 
visits. It also allowed the need for occupational therapy to 
trigger coverage of home health services furnished after June 
1981, although less than a year later, as part of a larger 
strategy to meet budget targets for reductions in Medicare 
spending, Congress removed occupational therapy as a qualifying 
trigger for home health care (Public Law 97-35, the Omnibus 
Reconciliation Act of 1981).
    Growth in volume of services and payments.--During the 
first 10 years of the Medicare Program, home health care 
accounted for less than 2 percent of total Medicare spending. 
Between 1977 and about 1990 it accounted for 2-3 percent of 
total program spending. This small increase reflected the 1980 
liberalizations and, many say, the delayed response to 
implementation in 1983 of a PPS for hospital inpatient care 
under Medicare. Some analysts had predicted that the inpatient 
PPS would lead to large growth in home health care utilization 
by Medicare beneficiaries. However, home health care spending 
increases that might have occurred as a result of the inpatient 
PPS were offset by changes in the law and in certain 
administrative procedures. For instance, the 1984 Deficit 
Reduction Act required HCFA to reduce the number of ``fiscal 
intermediaries'' with which HCFA contracts to process Medicare 
home health care claims. These entities approve or deny 
beneficiary eligibility for home health care as well as HHA 
claims for payment. As HCFA reduced the number of fiscal 
intermediaries, eligibility and claims decisions became more 
standardized. HCFA also intensified educational programs for 
claims processors, required HHAs to submit increased 
documentation with each claim, and increased the number of 
claims subjected to indepth medical reviews. Some say these 
actions tempered the effect of early hospital discharges 
prompted by the hospital inpatient PPS, noting that the home 
health care claims denial rate rose from 3.4 percent in 1985 to 
7.9 percent in 1987.
    A significant event in the history of the Medicare home 
health benefit was settlement of a class action lawsuit filed 
in 1988 (Duggan v. Bowen) which sought to liberalize HCFA's 
interpretation of benefit coverage requirements. As a result of 
the suit, in 1989, HCFA revised the home health eligibility 
criteria to cover patients needing ``part-time or intermittent 
care'' instead of the previous requirement that patients need 
``part-time and intermittent care.'' This change allowed the 
number of visits to be increased because they no longer had to 
be ``intermittent'' but could be made on a daily basis. HCFA's 
revised guidelines also loosened the claims procedures that had 
been tightened between 1985 and 1987. The revised guidelines 
may have opened the door to eligibility for persons who have 
ongoing medical problems that require personal care assistance 
associated more with long-term care rather than acute care.
    Home health spending rose from $2.1 billion in 1988 to 
$18.1 billion in 1996, an average annual increase of over 31 
percent (table 2-16). Medicare payment increases were driven by 
the increase in the number of beneficiaries served and the 
average number of visits per beneficiary served. The number of 
beneficiaries served more than doubled during this time period, 
and the average number of visits per home care patient 
increased more than threefold, from 23 visits in 1987 and 1988 
to 82 in 1997 (table 2-17). The number of HHAs participating in 
Medicare also increased sharply, growing from 5,686 agencies in 
1989 to 10,492 in 1997. However, the average cost per home care 
visit rose relatively modestly, from $55 in 1988 to $71 in 
1999, an increase of only 16 percent.

    Medicare payment policies for home health care.--Prior to 
the changes made by BBA 1997, Medicare reimbursed HHAs for the 
lesser of: (1) their reasonable costs; or (2) a limited amount 
per visit, applied in the aggregate. The per-visit limit was 
set at 112 percent of the national average cost, which was 
calculated separately for each type of service (nursing, 
therapy, etc.). It was based on costs for freestanding agencies 
(i.e., agencies not affiliated with hospitals) and varied 
according to whether an agency was located in an urban or rural 
area and according to wage level differentials from area to 
area. Per-visit cost limits were updated annually by applying 
an MBI to base-year data derived from HHA cost reports. These 
limits, however, were applied to aggregate agency payments and 
not to individual visits; that is, an aggregate cost limit was 
set for each agency equal to the sum of the agency's limit for 
each type of service multiplied by the number of visits of each 
type provided by the agency.
    This cost-based reimbursement system was criticized as 
providing few incentives for HHAs to maximize efficiency or 
control the volume of services they delivered because HHAs were 
paid for every visit their workers made.
Balanced Budget Act of 1997
    The Balanced Budget Act (BBA) of 1997 made several changes 
to home health eligibility, coverage, and payment rules. In 
general, through these changes, Congress sought to curtail the 
steep annual rates of increase in the volume of Medicare home 
health services and payments. In addition, BBA 1997 provided 
for the transfer of some home health spending from part A to 
part B; the purpose of this transfer was to reduce part A 
spending and thereby extend the solvency period of the part A 
trust fund.

    Clarification of coverage rules.--BBA 1997 included several 
provisions that clarified coverage criteria for home health 
care, including:
 1. Clarification of the definition of ``part-time'' and 
        ``intermittent'' regarding skilled nursing care and 
        home health aide services for purposes of eligibility 
        for, and coverage of home health care. First, patients 
        needing skilled nursing care are eligible for 
        Medicare's home health benefit if the need is for 
        ``intermittent'' care, defined as skilled nursing care 
        that is either provided or needed on fewer than 7 days 
        each week, or less than 8 hours of each day for periods 
        of 21 days or less (with extensions in exceptional 
        circumstances when the need for additional care is 
        finite and predictable). Second, for beneficiaries who 
        qualify for home health care and who need both skilled 
        nursing and home health aide services, coverage is 
        provided only to the extent that these two services 
        combined is ``part-time or intermittent,'' defined as 
        skilled nursing and home health aide services furnished 
        any number of days per week as long as they are 
        furnished (in combination) less than 8 hours each day 
        and 28 or fewer hours each week (or, subject to review 
        on a case-by-care basis as to the need for care, less 
        than 8 hours each day and 35 or fewer hours per week);
 2. Elimination of eligibility based solely on needing a 
        skilled nurse to draw blood;
 3. A requirement that claims include a physician identifier;
 4. A requirement that home health workers report their 
        activities during a visit in 15-minute intervals (the 
        data are used in designing a home health PPS);
 5. Extension of savings from a July 1994-June 1996 freeze on 
        home health cost limit updates;
 6. A requirement for a study of the definition of 
        ``homebound'' and a study to establish guidelines to 
        standardize the frequency and duration of home health 
        services for patients with similar needs and 
        circumstances (``normative guidelines''). (The 
        Secretary determined that no change was needed for the 
        definition of homebound, and the first results from the 
        study of normative guidelines will be available in fall 
        2000);
 7. A requirement for ``consolidated billing'' for services to 
        home health patients, under which payment for any 
        Medicare-covered service or item provided for a 
        beneficiary during a spell of home health care coverage 
        is to be made to the HHA. The HHA would then pay the 
        provider of the service or item. (BBRA 1999 later 
        excluded the supply of DME from consolidated billing.)
    Transfer certain coverage from part A to part B.--BBA 1997 
transfers from part A to part B payments for home health visits 
that are not part of the first 100 visits following a 
hospitalization. Part A benefits are financed through the 
Hospital Insurance (HI) Trust Fund, whereas part B benefits are 
financed by beneficiary premiums and general revenues. Thus, 
the solvency of the HI Trust Fund is extended by removing from 
it some of the costs of home health benefits. The transfer is 
being phased in over 6 years, between 1998 and 2003, with the 
Secretary transferring one-sixth of the aggregate expenditures 
associated with transferred visits in 1998 and an additional 
one-sixth each year thereafter until fully implemented in 2003. 
Beginning January 1, 2003, part A coverage for home health care 
will apply only to postinstitutional home health services for 
up to 100 visits during a spell of illness, except for those 
persons with part A coverage only, who will be covered for 
services without regard to the postinstitutional limitation.
    Moving home health care costs to part B could increase 
beneficiary premiums for that component of Medicare. The 
increase in the part B premium attributable to transferred 
expenditures will be phased in over a period of 7 years, 
between 1998 and 2004. For 1998 the part B premium was 
increased by one-seventh of the extra costs due to the 
transfer; for 1999 it was increased by two-sevenths, etc., 
until 2004 when the total cost of the transfer will be included 
in the part B premium. The increases have been very small, only 
slightly over $1 a month in 1999.
    Postinstitutional home health services are defined for 
these purposes as services furnished to a Medicare beneficiary: 
(1) after an inpatient hospital or rural primary care hospital 
stay of at least 3 consecutive days, initiated within 14 days 
after discharge; or (2) after a stay in an SNF, initiated 
within 14 days after discharge. A home health spell of illness 
is defined as the period beginning when a patient first 
receives postinstitutional home health services and ending when 
the beneficiary has not received inpatient hospital, SNF, or 
home health services for 60 days.
    Claims administration for transferred visits will continue 
to be done by part A fiscal intermediaries.
    Requirement for a PPS.--BBA 1997 required that a PPS be 
implemented for home health care beginning in 1999 and required 
that the PPS be designed to reduce home health payments by 15 
percent. It specified that the 15-percent reduction was to go 
into effect even if the PPS was not ready for implementation in 
1999. In Public Law 105-277 (the Omnibus Consolidated and 
Emergency Supplemental Appropriations Act for fiscal year 1999) 
Congress delayed the implementation date for the PPS until 
October 1, 2000, and moved the 15-percent reduction to coincide 
with commencement of the PPS. BBRA 1999 subsequently postponed 
the 15-percent reduction to 12 months after implementation of 
the PPS.
    Implementation of an interim payment system.--Because of 
concern about the rapidly rising costs of Medicare's home 
health benefit, Congress included in BBA 1997 an ``interim 
payment system'' (IPS) for home health care in order to achieve 
immediate spending reductions prior to implementation of the 
PPS. This interim system was effective for HHA cost reporting 
periods starting on or after October 1, 1997, and will remain 
in effect until the PPS is implemented in October 2000.
    Table 2-16 shows the substantial reductions in Medicare 
payments for home health services that have coincided with 
implementation of the IPS. In 1999, total payments were almost 
half the 1996 level. The IPS achieves cost savings by 
establishing a new methodology for limiting aggregate annual 
Medicare payments to individual HHAs. Under this procedure, an 
agency receives payments totaling the least of three amounts 
(pre-IPS payments were the lesser of the first two of these 
amounts): (1) the agency's reasonable costs; or (2) payments 
determined under the per-visit limits, with the limit set at 
106 percent of the national median cost per visit by service 
type (pre-IPS limit was 112 percent of the national average 
cost per visit); \1\ or (3) aggregate payments under a new 
formula based on per-beneficiary limits.
---------------------------------------------------------------------------
    \1\ Public Law 105-277 increased the limit from 105 percent of the 
national median cost of a service (estimated at the time of BBA 1997 
enactment to be about 98 percent of the mean) to 106 percent of the 
median.
---------------------------------------------------------------------------
    HCFA estimates that 79 percent of HHAs are subject to the 
new per-beneficiary limit; the others receive less under the 
reasonable cost or per-visit limit. Determining an agency's 
aggregate Medicare payment limit under the new per-beneficiary 
formula includes four steps:
 1. Divide the total payments the agency received from Medicare 
        for cost reporting periods ending in fiscal year 1994 
        by the number of Medicare patients it served that year 
        to get an average amount per beneficiary (certain wage 
        adjustments and cost updates are applied to bring the 
        amount up to values in the year to which the limits are 
        being applied, e.g., in 2000). Per-beneficiary limits 
        for agencies that were not operational in 1994 are set 
        at the national median;
 2. Reduce that average amount per beneficiary to 75 percent of 
        the full amount;
 3. Add a sum that is 25 percent of the average Medicare per-
        beneficiary costs of all agencies in the same census 
        region to get a new average cost per beneficiary;
 4. Multiply the agency's average cost per beneficiary from 
        step three by the number of Medicare patients the 
        agency is serving in the current year or cost reporting 
        period. The result is an aggregate annual payment limit 
        that an agency is held to for serving all its Medicare 
        patients in a cost reporting period under the IPS.
    If an agency's average costs for its patients are lower 
than others in the region, it benefits from the sum that is 
added based on the average regional per-beneficiary limits 
(step 3, above); if an agency's costs are higher than others in 
the area, it loses money from the regional component of the 
formula. This regional component of the formula also decreases 
disparities that had existed among agencies in the same general 
area.
    The per-beneficiary aggregate limit does not restrict the 
amount an HHA can spend on any individual beneficiary. It is 
simply a technique for arriving at an aggregate budget amount 
for an agency's Medicare patients. However, many HHAs 
misunderstood how this limit works, and there are reports that 
some agencies ended a patient's care when spending for that 
individual reached the amount of the per-beneficiary payment 
(i.e., the amount arrived at by step three above). In reality, 
agencies have some patients whose costs are below the per-
beneficiary average and some whose costs are above it. The idea 
behind the new formula was that payments on behalf of patients 
whose costs were lower than average would ``subsidize'' more 
costly patients; the balance of low and high cost patients 
would determine whether an agency would exceed its aggregate 
per beneficiary cap.
    Congress based the per-beneficiary calculation on fiscal 
year 1994 levels of operation in order to discount the large 
volume growth that still appeared to be occurring after that 
year (program costs grew by nearly 25 percent from 1994 to 
1995). Using fiscal year 1994 as the base year caused agencies 
that had increased their costs per patient after that time 
(generally by increasing the number of visits per patient) to 
have a larger reduction in their Medicare revenues under the 
IPS than agencies that had maintained relatively constant 
average costs per beneficiary.
    Response to BBA 1997 and the IPS.--Table 2-16 shows the 
significant decrease in Medicare spending for home health care 
that occurred with implementation of the provisions in BBA 1997 
and the IPS. Table 2-17 shows the sharp drop after 1997 in the 
number of home health visits covered by Medicare. At the same 
time, the average payment per visit increased. Most analysts 
agree that the reduction in the number of home health visits is 
attributable largely to the IPS, but note also that the 
provision of BBA 1997 that eliminated venipuncture (the drawing 
of a blood specimen) as the sole home health service qualifying 
an individual for home care also contributed to the reduction 
in visits. Presumably, elimination of less costly visits (e.g., 
home health aide visits) resulted in an increase in the average 
payment per visit from $64 in 1997 to $71 in 1999. Moreover, 
the Health Insurance Portability and Accountability Act of 1996 
included civil money penalties for physicians who falsely 
certify that a beneficiary needs home health care, a provision 
some say has had a chilling effect on physician referrals.
    As the apparent effects of the IPS began to be evident, 
representatives of the home health industry claimed that (1) 
the IPS was limiting HHAs' ability to provide necessary care; 
(2) agencies with low average costs per beneficiary in the 
fiscal year 1994 base period were realizing the severest 
reductions; and (3) these older agencies were being paid 
inequitably in comparison with newer agencies because agencies 
that had not been in business long enough to have had a cost 
reporting period ending in fiscal year 1994 were assigned a 
per-beneficiary limit equal to the national median.
    Because the payment limits imposed by the IPS induce 
agencies to balance the number of expensive patients against 
the number of inexpensive patients they serve in order to stay 
within their total Medicare payment limit, questions arose 
about whether the IPS created incentives for HHAs to refuse to 
serve beneficiaries with the most serious medical needs and who 
require extensive home health visits. An HHA might refuse to 
accept certain expensive patients if it were concerned that the 
balance of patients in its caseload would be tipped too far 
toward costly cases and result in expenditures exceeding the 
agency's total funding limit.
    In January 1998, the Congressional Budget Office (CBO) 
projected 10-year BBA 1997 home health care savings of almost 
$75 billion. In March 1999, CBO reestimated the effects of BBA 
1997, and the new projections showed an additional $56 billion 
in savings. The original CBO estimate reflected an annual rate 
of growth in home health spending of 8.3 percent a year over 10 
years, but the revised estimate showed an annual increase of 
5.6 percent a year. (Under the old law, in the early 1990s, 
Medicare home health spending had been growing at rates of 
between 20 and 30 percent a year.) However, CBO's revised 
estimates included changes in their underlying economic 
assumptions as well as revised estimates of the effects of BBA 
1997. Additionally, HCFA officials cautioned that reduced 
Medicare payments for home health care since 1997 reflect an 
intensified case review process HCFA required claims processors 
to implement along with the IPS as well as stepped-up fraud and 
abuse detection activities.
    To address concerns about the impact of the IPS and the 
large decrease in estimates of program payments for home health 
care, in Public Law 105-277, Congress modified the IPS formula 
to increase per-visit limits for HHAs from 105 percent of the 
median to 106 percent and increased payments to agencies whose 
per-beneficiary limits under the IPS were less than the 
national median per-beneficiary limits. The per-beneficiary 
limits for older agencies (those in operation in fiscal year 
1994) were increased by one-third of the difference between the 
agency's per-beneficiary limit and the national median of per-
beneficiary limits; per-beneficiary limits for agencies 
starting operation after fiscal year 1994 but before fiscal 
year 1999 were set at the national median limit; new HHAs that 
began treating Medicare patients on or after October 1, 1998, 
were set at 75 percent of the national median, with a 2-percent 
reduction. These modifications to home health payments were 
estimated to increase Medicare payments to 65 percent of HHAs.
 Home health prospective payment system
    As noted above, BBA 1997 required a prospective payment 
system (PPS) to be implemented for Medicare payments for home 
health care. Final PPS rules were published in the Federal 
Register on July 3, 2000. Under those rules, beneficiaries are 
categorized into one of 80 home health resource groups, each of 
which carries a standard payment for a 60-day episode of care 
for a beneficiary. The standard payment is computed using the 
average national cost per visit (computed and weighted by visit 
type, that is, skilled nursing, physical therapy, etc.) 
multiplied by the national average number of visits (by type) 
in a 60-day period. Average costs for nonroutine medical 
supplies, certain therapy services, and administration of the 
outcome and assessment information set (OASIS) interview 
questionnaire are added.\2\ The payments include adjustments to 
reflect geographic wage levels among HHAs, to account for 
unusually costly patients (``outlier'' payments), and to 
achieve ``budget neutrality.'' The budget neutrality adjustment 
ensures that total home health payments under the PPS in fiscal 
year 2001 will be equal to the estimated total payments that 
would have been made by Medicare in that year had the IPS 
continued in effect in fiscal year 2001, including limits on 
the market basket index (MBI). Total fiscal year 2001 payments 
will equal the IPS projected to that year minus 1.1 percentage 
points.
---------------------------------------------------------------------------
    \2\ OASIS is a data collection instrument on which a home health 
worker records, for new or renewing patients, clinical and other data 
required to plan the individual's course of care. Data from OASIS are 
also used in the definition of the payment categories under the home 
health PPS.
---------------------------------------------------------------------------
    Special payment arrangements are made for beneficiaries 
receiving fewer than five visits, or who transfer from one HHA 
to another, or who have a significant change in their condition 
during an episode of illness.
    HHAs will be paid 60 percent of the PPS amount after 
completing an OASIS questionnaire for each new or renewing 
patient and receiving a physician's certification and plan of 
care. The remainder of the payment will be made when the 
episode is completed (or, if earlier, when care is completed). 
If, at the end of an initial 60-day episode, a physician orders 
care to be continued, payment for the subsequent episode (or 
episodes) is split to provide 50 percent of the payment at the 
start of the episode and 50 percent at the end of care or the 
episode.
Balanced Budget Refinement Act (BBRA) of 1999
    As a result of concern that many provisions of BBA 1997 had 
caused unanticipated reductions in Medicare payments across the 
spectrum of health care providers, Congress included 
modifications to Medicare in BBRA 1999. That act included the 
following provisions pertaining to Medicare home health care:
 1. Delays the 15-percent payment reduction required under the 
        PPS by BBA 1997 until 12 months after implementation of 
        the PPS and requires the Secretary to report within 6 
        months after implementation of the PPS on the need for 
        the 15 percent or some other reduction.
 2. Provides HHAs with a payment of $10 per beneficiary for 
        administration of the OASIS questionnaire to new home 
        health patients for services furnished during cost 
        reporting periods in fiscal year 2000. One-half of the 
        payment will be made in April 2000 and the remainder at 
        cost report settlement. It requires GAO to study the 
        costs of collecting these data and to report by April 
        2000.
 3. Requires that per-beneficiary limits under BBA 1997 IPS be 
        increased by 2 percent in cost reporting periods 
        starting in fiscal year 2000 for those HHAs for which 
        the per-beneficiary limit is below the national median; 
        the increase will not be included in the base for 
        determining the budget neutral PPS amounts.
 4. Establishes the surety bond requirement for HHAs as the 
        lesser of $50,000 or 10 percent of an HHA's Medicare 
        payments in the previous year and requires the bond to 
        be in effect for 4 years (or longer if ownership of the 
        HHA changes). Prior periods covered by a bond may be 
        counted and Medicare and Medicaid bond requirements are 
        to be coordinated.
 5. Excludes DME from the home health consolidated billing 
        requirement of BBA 1997.
 6. Clarifies that the increase in the home health PPS in 
        fiscal year 2002 and fiscal year 2003 will be the MBI 
        minus 1.1 percentage points.
 7. Requires the Medicare Payment Advisory Commission to study 
        and report within 2 years of enactment on the 
        feasibility and advisability of excluding rural HHAs 
        and beneficiaries living in rural areas from the home 
        health PPS.
    Because the new PPS will go into effect in fiscal year 
2001, the BBRA 1999 provisions pertaining to home health care 
under Medicare were not extensive. However, the provision that 
had caused substantial concern in the industry was the 
requirement that the PPS be designed to reduce total Medicare 
payments for home health care by 15 percent compared with pre-
PPS levels. Because of the sharp declines in payments to HHAs 
under the IPS, some said that a further 15-percent reduction 
would affect the availability of home health services and make 
care inaccessible to beneficiaries, particularly those with 
extensive and costly care needs. Congress addressed that issue 
in BBRA 1999 by delaying implementation of the 15-percent 
reduction until 12 months after implementation of the PPS and 
requiring the Secretary to evaluate and report, within 6 months 
of implementation of the PPS, on the need for payment 
reductions.

                            Hospice Services

Coverage and benefits
    Medicare covers hospice care, in lieu of most other 
Medicare benefits, for terminally ill beneficiaries. Hospice 
care emphasizes palliative medical care, that is, relief from 
pain, and supportive social and counseling services for the 
terminally ill and their families. Services are provided 
primarily in the patient's home. The Tax Equity and Fiscal 
Responsibility Act of 1982 (TEFRA), Public Law 97-248, first 
authorized Medicare part A coverage for hospice care (for the 
period November 1, 1983 to October 1, 1986); in 1986, Congress 
made the hospice benefit a permanent part of the Medicare 
Program, effective April 7, 1986.
    For a person to be considered terminally ill and eligible 
for Medicare's hospice benefit, the beneficiary's attending 
physician and the medical director of the hospice (or physician 
member of the hospice team) must certify that the individual 
has a life expectancy of 6 months or less. As a result of an 
amendment in BBA 1997, persons electing hospice are covered for 
two 90-day periods, followed by an unlimited number of 60-day 
periods. The medical director or physician member of the 
hospice team must recertify at the beginning of each new 
election period that the beneficiary is terminally ill. 
Services must be provided under a written plan of care 
established and periodically reviewed by the individual's 
attending physician and by the medical director of the hospice.
    Covered hospice services include the following: (1) nursing 
care provided by or under the supervision of a registered 
nurse; (2) physical or occupational therapy or speech-language 
pathology services; (3) medical social services; (4) services 
of a home health aide who has successfully completed a training 
program approved by the Secretary of the U.S. Department of 
Health and Human Services (DHHS); (5) homemaker services; (6) 
medical supplies (including drugs and biologicals) and the use 
of medical appliances; (7) physician services; (8) short-term 
inpatient care (including both respite care and procedures 
necessary for pain control and acute and chronic symptom 
management); (9) counseling, including dietary counseling, for 
care of the terminally ill beneficiary and for adjustment to 
the patient's death (bereavement counseling is not a 
reimbursable service); and (10) any other item or service which 
is specified in a patient's plan of care and which Medicare may 
pay for.
    Medicare's hospice benefit is intended to be principally an 
in-home benefit. For this reason, Medicare law prescribes that 
respite care, or relief for the primary care giver of the 
terminally ill patient, may be provided only on an 
intermittent, nonroutine, and occasional basis and may not be 
provided consecutively over longer than 5 days. In addition, 
the aggregate number of inpatient care days provided in any 12-
month period to Medicare beneficiaries electing hospice care 
can not exceed 20 percent of the total number of days of 
hospice coverage provided to these persons.
    Only two covered hospice services--outpatient drugs or 
biologicals and respite care--are subject to coinsurance. 
Outpatient drugs and biologicals are subject to a coinsurance 
amount that approximates 5 percent of the cost of the drug to 
the hospice program, except that the amount may not exceed $5 
per prescription. For respite care, coinsurance equals 5 
percent of program payments for respite, but may not exceed 
Medicare's inpatient hospital deductible during a hospice 
coinsurance period (defined as the period when hospice election 
is not broken by more than 14 days).
    Covered services must be provided by a Medicare-certified 
hospice. Certified hospices must be either public agencies or 
private organizations primarily engaged in providing covered 
hospice services and must make services available on a 24-hour 
basis, in individuals' homes, on an outpatient basis, and on a 
short-term inpatient basis. Hospices must routinely and 
directly provide substantially all of the following ``core'' 
services: nursing care, medical social services, and counseling 
services. The remaining hospice services may be provided either 
directly by the hospice or under arrangements with others. If 
services are provided through arrangements with other 
providers, the hospice must maintain professional management 
responsibility for all such services, regardless of the 
facility in which the services are furnished.
    The hospice program must also have an interdisciplinary 
group of personnel which includes at least one registered 
professional nurse and one social worker employed by the 
hospice; one physician employed by or under contract with the 
hospice; plus at least one pastoral or other counselor.
Reimbursement
    In implementing Medicare's hospice benefit, HCFA 
established a prospective payment methodology. Under this 
methodology, hospices are paid one of four prospectively 
determined rates, which correspond to four different levels of 
care, for each day a Medicare beneficiary is under the care of 
the hospice. Reimbursement will thus vary by the length of the 
patient's period in the hospice program as well as by the 
characteristics of the services (intensity and site) furnished 
to the beneficiary.
    The four rate categories for reimbursing hospices are:
 1. Routine home care day.--Routine home care day is a day on 
        which an individual is at home and is not receiving 
        continuous home care. The routine home care rate is 
        paid for every day a patient is at home and under the 
        care of the hospice regardless of the volume or 
        intensity of the services provided on any given day as 
        long as less than 8 hours of care are provided. This 
        rate is $98.96 for services provided between October 1, 
        1999 and September 30, 2000.
 2. Continuous home care day.--A continuous home care day is a 
        day on which an individual receives hospice care 
        consisting predominantly of nursing care on a 
        continuous basis at home. Home health aide or homemaker 
        services or both may also be provided on a continuous 
        basis. Continuous home care is furnished only during 
        brief periods of crisis and only as necessary to 
        maintain the terminally ill patient at home. Home care 
        must be provided for a period of at least 8 hours 
        before it would be considered to fall within the 
        category of continuous home care. Payment for 
        continuous home care will vary depending on the number 
        of hours of continuous services provided. Currently 
        this rate is $577.59 for 24 hours or $24.07 per hour.
 3. Inpatient respite care day.--An inpatient respite care day 
        is one on which the individual who has elected hospice 
        care receives care in an approved facility on a short-
        term (not more than 5 days at a time) basis for the 
        respite of his caretakers. Currently this rate is 
        $102.37.
 4. General inpatient care day.--A general inpatient care day 
        is one on which an individual receives general 
        inpatient care in an inpatient facility for pain 
        control or acute or chronic symptom management which 
        cannot be managed in other settings. Care may be 
        provided in a hospital, skilled nursing facility (SNF), 
        or inpatient unit of a freestanding hospice. Currently 
        this rate is $440.22.
    To reflect differences in wage levels from area to area, 
each of these four payment rates is adjusted by the hospital 
area wage index used by Medicare for adjusting payments to 
hospitals, SNFs, and HHAs. HCFA separates each of the national 
payment rates for hospice care into components which reflect 
the estimated proportion of the rate attributable to wage and 
nonwage costs. The wage component of each rate is then adjusted 
by the index applicable to the area in which the hospice is 
located.
    The Omnibus Budget Reconciliation Act (OBRA) of 1989 
required that the payment rates be increased by the hospital 
market basket percentage increase each fiscal year. OBRA 1993, 
however, reduced the updates for the prospective rates as 
follows: for fiscal year 1994, the hospital market basket 
percentage increase minus 2.0 percentage points; for fiscal 
years 1995 and 1996, the hospital market basket minus 1.5 
percentage points; and for fiscal year 1997, market basket 
minus 0.5 percentage points.
    BBA 1997 reduced the hospice payment update to market 
basket minus 1.0 percentage point for each of fiscal years 
1998-2002.
    Medicare law requires that payments to a hospice for care 
furnished over the period of a year be limited to a ``cap 
amount.'' The cap amount is applied on an aggregate rather than 
a case-by-case basis. Therefore, each individual hospice's cap 
amount is calculated by multiplying the yearly cap amount by 
the number of Medicare beneficiaries who received hospice care 
from the hospice during the cap period. Medicare defines a cap 
year as the period from November 1 through October 31 of the 
following year. The cap amount for the period November 1, 1999 
through October 31, 2000, is $15,313.
Updates to hospice payment amounts
    Hospice daily payment rates for routine home care, 
continuous home care, inpatient respite care, and general 
inpatient care are updated annually by the increase in the 
hospital MBI. BBA 1997 reduced these updates to the market 
basket increase minus 1.0 percentage point for fiscal years 
1998-2002. However, BBRA 1999 increased the rates otherwise in 
effect for fiscal year 2001 by 0.5 percentage points and for 
fiscal year 2002 by 0.75 percentage points.
    The hospice cap amount is adjusted annually by the 
percentage change in the medical care component of the Consumer 
Price Index for All Urban Consumers (CPI-U).
 Hospice program data
    Table 2-18 shows that the number of hospices participating 
in Medicare grew from 553 in fiscal year 1988 to 2,293 in 
fiscal year 1998.
    Total Medicare payments for hospice care in fiscal year 
1988, 2 years after it became a permanent part of the Medicare 
Program, totaled less than $120 million. Daily payment rates in 
effect in 1989 were increased by 20 percent in 1990, which led 
to more serv-

ices becoming available. As shown in table 2-19, Medicare 
payments for hospice care increased to $445.4 million in fiscal 
year 1991 and subsequently to nearly $2.2 billion in fiscal 
year 1998.
    From fiscal year 1991 through fiscal year 1998 the number 
of beneficiaries using Medicare's hospice benefit increased 
nearly fourfold, from 108,413 to 401,140, although the average 
payment per beneficiary increased by less than one-third, from 
$4,108 to $5,412.
    The data show that the average number of days of hospice 
utilization increased sharply from fiscal year 1991 to fiscal 
year 1992, reflecting the 20-percent increase in payment rates 
and concomitant increase in availability and utilization of 
this care. However, after 1995 the average duration of coverage 
declined. The decline may be the result of: (1) continued 
reluctance of physicians to refer patients to hospice rather 
than continue treatment; (2) the availability of new treatment 
therapies; and (3) increased regulatory scrutiny and focused 
medical reviews.

                 PART B SERVICES--COVERAGE AND PAYMENTS

                          Physicians Services

    Medicare pays for physicians services on the basis of a fee 
schedule which went into effect in 1992. The fee schedule 
assigns relative values to services. Relative values reflect 
three factors: physician work (time, skill, and intensity 
involved in the service), practice expenses, and malpractice 
costs. These relative values are adjusted for geographic 
variations in the costs of practicing medicine. Geographically-
adjusted relative values are then converted into a dollar 
payment amount by a dollar figure known as the conversion 
factor. The 2000 conversion factor is $36.61.
    The annual percentage update to the conversion factor 
equals the Medicare economic index (which measures inflation) 
subject to an adjustment to match spending for physicians 
services under the sustainable growth rate system. This 
adjustment sets the conversion factor at a level so that 
projected spending for a year will meet allowed spending by the 
end of the year. Allowed spending for a year is calculated 
using the sustainable growth rate. However, in no case can the 
conversion factor update be more than 3 percentage points 
above, nor more than 7 percentage points below, the Medicare 
economic index.
    For a discussion of how Medicare calculates payments to 
physicians, see appendix D.
    Anesthesiologists are paid under a separate fee schedule 
which uses base and time units. A separate conversion factor 
($17.77 in 2000) applies.
    Medicare payments are made for physicians' services after 
the annual deductible requirement of $100 has been satisfied. 
Payment is set at 80 percent of the fee schedule with 
beneficiaries responsible for the remaining 20 percent, which 
is referred to as coinsurance.
    Medicare payment is made either on an ``assigned'' or 
``unassigned'' basis. By accepting assignment, physicians agree 
to take the Medicare fee schedule amount as payment in full. 
Thus, if assignment is accepted, beneficiaries are not liable 
for any out-of-

pocket costs other than standard deductible and coinsurance 
payments. In contrast, if assignment is not accepted, 
beneficiaries may be liable for charges in excess of the 
Medicare approved charge, subject to limits. This process is 
known as balance billing.
    Medicare's Participating Physician Program was established 
to provide beneficiaries with the opportunity to select 
physicians (designated as ``participating physicians'') who 
have agreed to accept assignment on all services provided 
during a 12-month period. Nonparticipating physicians continue 
to be able to accept or refuse assignment on a claim-by-claim 
basis. There are a number of incentives for physicians to 
become participating physicians, the chief of which is that the 
fee schedule payment amount for nonparticipating physicians is 
only 95 percent of the recognized amount paid to participating 
physicians. Additional incentives include more rapid claims 
payment and widespread distribution of participating physician 
directories.
    Nonparticipating physicians may not charge more than 115 
percent of Medicare's allowed amount for any service. 
Medicare's allowed amount for nonparticipating physicians is 
set at 95 percent of that for participating physicians. Thus, 
nonparticipating physicians are only able to bill 9.25 percent 
(115 percent times 95 percent) over the approved amount for 
participating physicians.

                 Services of Nonphysician Practitioners

    The physician fee schedule is also used for calculating 
payments made for certain services provided by nonphysician 
practitioners.
Physician assistants and nurse practitioners
    Separate payments are made for physician assistant 
services, when provided under the supervision of a physician. 
Separate payments are also made for nurse practitioner 
services, provided in collaboration with a physician.
    Payment for these services can only be made if no facility 
or other provider charges are paid in connection with the 
service. Payment equals 80 percent of the lesser of either the 
actual charge or 85 percent of the fee schedule amount for the 
same service if provided by a physician. For assistant-at-
surgery services, payment equals 80 percent of the lesser of 
either the actual charge or 85 percent of the amount that would 
have been recognized for a physician serving as an assistant-
at-surgery. The physician assistant may be in an independent 
contractor relationship with the physician.
Certified nurse midwife services
    Certified nurse midwife services are paid at 65 percent of 
the physician fee schedule amount.
Certified registered nurse anesthetists
    Certified registered nurse anesthetists are paid under the 
same fee schedule used for anesthesiologists (see above). 
Payments for services furnished by an anesthesia care team 
composed of an anesthesiologist and a certified registered 
nurse anesthetist are capped at 100 percent of the amount that 
would be paid if the anesthesiologist were practicing alone. 
The payments are evenly split between each practitioner.
Clinical psychologists and clinical social workers
    Diagnostic and therapeutic services provided by clinical 
psychologists are paid under the physician fee schedule. 
Payments for services provided by clinical social workers are 
equal to 75 percent of the amount allowed for clinical 
psychologists. Some services are subject to the psychiatric 
services limitation which limits Medicare payments for some 
services to 50 percent of incurred expenses.
Physical or occupational therapists
    Payments for physical therapy and occupational therapy 
services are made under the physician fee schedule. In 1999, an 
annual $1,500 per-beneficiary limit applied to all outpatient 
physical therapy services (including speech-language pathology 
services), except for those furnished by a hospital outpatient 
department (OPD). A separate $1,500 limit applied to all 
outpatient occupational therapy services except for those 
furnished by hospital OPDs. Therapy services furnished as 
incident to physicians professional services were included in 
these limits.
    The $1,500 limits were to apply each year. However, BBRA 
1999 suspended application of these limits in 2000 and 2001. 
Thus, no limits apply in these 2 years. The limits are slated 
to apply again in 2002.

                      Clinical Laboratory Services

    Medicare provides coverage for diagnostic clinical 
laboratory services. These services may be provided by an 
independent laboratory, a physician's office laboratory, or a 
hospital laboratory to outpatients. Since 1984, Medicare has 
paid for clinical laboratory services on the basis of a fee 
schedule. Fee schedules have been established on a carrier 
service area basis. The law set the initial payment amount for 
services performed in physicians' offices or independent 
laboratories at the 60th percentile of the prevailing charge 
established for the 12-month period beginning July 1, 1984. 
Similarly, the initial fee schedule payment amount for services 
provided by hospital-based laboratories serving hospital 
outpatients was set at the 62d percentile of the prevailing 
charge level. Subsequent amendments to the payment rules 
limited application of the hospital fee schedule to ``qualified 
hospitals.'' A qualified hospital is a sole community hospital 
(as that term is used for payment purposes under Medicare's 
hospital prospective payment system (PPS)) which provides some 
clinical diagnostic tests 24 hours a day in order to serve a 
hospital emergency room which is available to provide services 
24 hours a day, 7 days a week.
    The fee schedule payment amounts have been increased 
periodically since 1984 to account for inflation. The updates 
have generally occurred on January 1 of each year. The Balanced 
Budget Act (BBA) of 1997 eliminated the updates for 1998-2002. 
It also set the national ceiling on payment amounts at 74 
percent of the median for all fee schedules for that test. BBA 
1997 required the Secretary to adopt uniform coverage, 
administration, and payment policies for laboratory tests using 
a negotiated rulemaking process. The policies would be designed 
to eliminate variation among carriers and to simplify 
administrative requirements. A proposed rule was issued March 
10, 2000.
     BBA 1997 also required the Secretary to divide the country 
into no more than five regions and designate a single carrier 
for each region to process laboratory claims (excluding those 
for services provided to inpatients of hospitals and SNFs). The 
allocation of claims to a particular carrier would be based on 
whether the carrier served the geographic area where the 
specimen was collected by another method selected by the 
Secretary. The requirement would not apply to those physicians' 
office laboratories that the Secretary determined would be 
unduly burdened by the application of billing responsibilities 
with respect to more than one carrier. This requirement has not 
been implemented.
    Payment for clinical laboratory services (except for those 
provided by a rural health clinic) may only be made on the 
basis of assignment. The law specifically applies the 
assignment requirement to clinical laboratory services provided 
in physicians' offices. Payment for clinical laboratory 
services equals 100 percent of the fee schedule amount; no 
beneficiary cost sharing is imposed.
    Laboratories must meet the requirements of the Clinical 
Laboratory Improvement Act Amendments of 1988. This 
legislation, which focused on the quality and reliability of 
medical tests, expanded Federal oversight to virtually all 
laboratories in the country, including physician office 
laboratories.

        Durable Medical Equipment and Prosthetics and Orthotics

    Medicare, under part B of the program, covers a wide 
variety of medical supplies if they are medically necessary and 
are prescribed by a physician. Under the program, durable 
medical equipment (DME) includes such items as hospital beds, 
intermittent positive pressure breathing machines, blood 
glucose monitors, and wheelchairs. Guidelines define DME as 
equipment that: (1) can withstand repeated use; (2) is 
primarily and customarily used to serve a medical purpose; (3) 
generally is not useful to a person in the absence of an 
illness or injury; and (4) is appropriate for use in the home. 
All of these requirements must be met before an item can be 
covered. The benefit also includes related supplies, such as 
drugs and biologicals that are necessary for the effective use 
of the product.
    Medicare also covers prosthetic devices. These are defined 
as items that replace all or part of an internal body organ, 
such as colostomy bags, pacemakers, breast prostheses for 
postmastectomy patients, parental and enteral nutrients, and 
intraocular lenses. Prosthetics and orthotics include such 
items as leg, arm, back and neck braces, and artificial legs, 
arms, and eyes.
Reimbursement for durable medical equipment
    Medicare pays for DME on the basis of a fee schedule 
originally established by the Omnibus Budget Reconciliation Act 
of 1987 (OBRA 1987). Under the DME fee schedule, Medicare pays 
the lower of either 80 percent of the item's actual charge or 
the fee schedule amount. For payment purposes, covered DME 
items are classified into five groups: (1) inexpensive or 
routinely purchased DME (defined as equipment that costs less 
than $150, or is purchased at least 75 percent of the time); 
(2) items requiring frequent and substantial servicing; (3) 
customized items (defined as equipment constructed or modified 
substantially to meet the needs of an individual patient); (4) 
other items of DME (frequently referred to as the ``capped 
rental'' category); and (5) oxygen and oxygen equipment. Some 
items that do not meet the definition of DME, such as 
disposable surgical dressings, are also covered under the fee 
schedule.
    In general, the fee schedule payment rates for DME are 
determined locally (on a statewide basis). However, these local 
payments are subject to floor and ceiling limits determined 
nationally. Medicare will not pay less than 85 percent of the 
median of all local payment amounts (floor), and will not pay 
more than 100 percent of this median (ceiling).
    Prosthetics and orthotics are also paid according to a fee 
schedule similar to the DME fee schedule. The payment rates are 
determined regionally and are subject to national limits which 
also have ceilings and floors. The floor is 90 percent of the 
weighted average of all regional payment amounts, and the 
ceiling is 120 percent of this weighted average.
    The fee schedules are generally updated annually by the 
CPI-U. However, BBA 1997 froze payments for DME at the 1997 
level for fiscal years 1998-2002. For oxygen and oxygen 
equipment, BBA 1997 reduced payment limits beginning in fiscal 
year 1999 to 70 percent of 1997 levels. The update for 
prosthetics and orthotics was limited to 1.0 percent through 
fiscal year 2002. The Balanced Budget Refinement Act (BBRA) of 
1999 amended this provision as it related to DME (including 
oxygen), allowing an update for fiscal year 2001 equal to 0.3 
percent over fiscal year 2000 levels; for fiscal year 2002 the 
update is 0.6 percent over fiscal year 2000 levels. Prosthetics 
and orthotics updates were not affected by BBRA 1999.
    Medicare pays for a few items of medical equipment on a 
reasonable cost basis, rather than under the fee schedule. 
These include splints, casts, home dialysis equipment, 
therapeutic shoes, and blood products. BBA 1997 authorized the 
Secretary to establish fee schedules for these items; 
regulations were proposed in July 1999.
    Table 2-20 shows total Medicare spending in calendar year 
1998 for DME, prosthetics and orthotics, and certain other 
items.
    Inherent reasonableness authority.--If the Secretary 
determines that using standard procedures to calculate payment 
for an item under the fee schedule results in an amount which 
is ``grossly excessive or grossly deficient and not inherently 
reasonable,'' the Secretary is authorized to increase or 
decrease the payment amount accordingly. The authority to make 
these adjustments is generally referred to as the inherent 
reasonableness authority. It involves a complex procedure of 
investigation, commentary, and notification.
     BBA 1997 sought to simplify the procedure and widen the 
application of this authority, requiring HCFA to publish 
criteria for determining if a fee schedule charge was 
inherently unreasonable, and the factors to be used in 
determining charges that are realistic and equitable. Using 
these criteria, the Secretary would be permitted to adjust 
payment levels. HCFA published interim final regulations (63 
Federal Register 687, January 7, 1998) naming criteria such as 
competitiveness in a particular marketplace, changes in 
technology or supplier costs, and amounts paid by other 
purchasers in the same area. However, industry voiced concerns 
about how use of this authority might affect prices and 
beneficiary access to services. As a result, in BBRA 1999, 
Congress prohibited use of the inherent reasonableness 
authority until the GAO reports on how the authority is used.

Administering the DME benefit
    HCFA enters into contracts with insurance companies known 
as carriers under part B of Medicare, to administer the 
program, i.e., to process claims and make payments. In the case 
of DME, administration is centralized in four regional carriers 
(known as DME regional carriers, or DMERCs) who are responsible 
for processing claims for all beneficiaries living within their 
areas. As a result of the consolidation, which occurred in 
1992, variation in coverage policy and utilization patterns has 
been reduced.
    Suppliers provide Medicare beneficiaries with medical 
equipment and bill the regional carrier in their area. Most 
suppliers are small entities located in areas where the demand 
is greatest. Before being issued a Medicare supplier number, 
suppliers must comply with various standards. These include 
maintaining a physical location, filling orders from their own 
inventories or under contract with another company, being 
responsible for deliveries to beneficiaries and honoring all 
product warranties, and providing proof of appropriate 
liability insurance. BBA 1997 required that suppliers provide a 
$50,000 surety bond issued by a company approved by the 
Treasury Department. Although regulations have been proposed 
for this requirement, they have not been finalized.
Competitive bidding
    Investigations have shown that Medicare pays higher prices 
for certain medical supplies than those paid by other health 
care insurers and other government agencies, including the 
Department of Veterans Affairs. In order to lower payments, the 
Secretary currently must initiate the inherent reasonableness 
process or rely on legislation. Many observers suggested 
granting HCFA the authority to engage in a competitive bidding 
arrangement similar to the one used by the Department of 
Veterans Affairs. BBA 1997 provided such authority on a limited 
basis. HCFA was authorized to establish five 3-year competitive 
bidding demonstration projects.
    With the demonstration projects, HCFA intends to test how 
effective competitive bidding is for the Medicare Program. 
Goals for the projects are to maintain beneficiary access to 
services and limit their out-of-pocket expenses while lowering 
Medicare's payment for medical equipment. The projects will 
also prevent Medicare from dealing with suppliers who engage in 
fraudulent business practices.
    The first demonstration project site selected was in Polk 
County, FL. Beginning in 1999, suppliers submitted bids to 
HCFA, competing for the right to supply certain medical 
equipment to the 92,000 Medicare beneficiaries in the area. 
Bids were evaluated on the basis of quality and price. To 
maintain beneficiary access to the medical equipment, HCFA 
named between 4 and 13 companies for each item. HCFA expects 
that savings will average 17 percent on medical equipment 
overall, and will be as high as 30 percent for some products.
    A second demonstration project is expected to begin in 
January 2001 in the San Antonio area of Texas. The project, 
involving about 112,000 Medicare beneficiaries, will be similar 
to the Polk County project, although different products will be 
involved. In 1998, Medicare paid an average of $287 per 
beneficiary in the San Antonio area for medical equipment.

                Hospital Outpatient Department Services

    Hospital outpatient department (OPD) services for Medicare 
beneficiaries are paid under Medicare part B. Services provided 
in OPDs include: (1) emergency room and clinic services; (2) 
surgery and operating rooms; (3) laboratory and pharmacy 
services; (4) physical therapy and rehabilitation services; (5) 
DME; and (6) chemotherapy and radiation therapy. OPDs also 
provide diagnostic and preventive procedures such as radiology, 
computer axial tomography (CAT) scans, magnetic resonance 
imaging, endoscopies, and colonoscopies.
    Table 2-21 shows the percent distribution of hospital OPD 
charges by type of service provided to Medicare beneficiaries 
in 1998. For example, it shows that, of the $50.6 billion in 
hospital outpatient charges (table 2-22) for Medicare 
beneficiaries, 20.6 percent were for radiology services, 12.8 
percent were for laboratory services, and so forth.

Background
    In the early years of the Medicare Program, Medicare paid 
for both inpatient and outpatient hospital care based on a 
hospital's reasonable costs attributable to caring for Medicare 
beneficiaries. These were retrospective payment systems, 
meaning payment for the costs incurred in providing care was 
determined and made after the service was rendered.
    Payment systems for hospital inpatient care and outpatient 
services were separated in 1983 when a new prospective system 
was implemented for inpatient care. Under that arrangement, a 
hospital receives a fixed payment, known in advance of 
providing care, covering all care and services required by a 
patient during a hospital stay (exclusive of physician fees) 
and determined by the diagnosis-related group (DRG) into which 
the patient is classified at admission. However, outpatient 
services remained under the costs-or-charges retrospective 
payment arrangement.
    Throughout the 1980s, Medicare payments for hospital 
outpatient services grew as the volume of services provided in 
that setting increased. Although growth in the Medicare 
population contributed to increased utilization of outpatient 
care, a substantial share of the growth in the volume of 
outpatient services is attributable to advances in medicine and 
technology that permit procedures formerly restricted to the 
inpatient hospital setting to be provided safely on an 
outpatient basis. Implementation in 1983 of the inpatient PPS, 
which included aggressive management of inpatient utilization, 
also led to a shift in care from hospital inpatient to 
outpatient departments. Currently, on average, outpatient 
services generate about half of all hospital revenues.
    Since the early 1980s, Medicare's payments for OPD services 
have grown for reasons other than increased volume, and that 
growth is often attributed to the lack of incentives for 
efficiency or cost control inherent in the retrospective cost-
based payment system. Congress sought to contain the rate of 
increase in Medicare payments for certain outpatient services 
by requiring implementation of ``fee schedules'' (a form of 
PPS) to pay for those services. For example, Congress required 
HCFA to establish fee schedules for many outpatient diagnostic 
procedures and tests; provision of orthotics, prosthetics, and 
other DME; dialysis for persons with end-stage renal disease 
(ESRD); and surgeries that might also take place in another 
outpatient setting such as ambulatory surgical centers (ASCs). 
These fee schedules save Medicare money because the amounts 
paid are generally less than payments under retrospective cost 
reimbursement systems.
    In the Omnibus Budget Reconciliation Acts of 1986 and 1990, 
Congress directed the Secretary of the U.S. Department of 
Health and Human Services (DHHS) to develop a PPS for all 
hospital OPD care. In addition, to achieve more immediate 
savings, legislation required across-the-board reductions in 
Medicare payments for hospital operating costs and capital 
costs (including those associated with outpatient care) 
starting in 1990.
    Although Medicare currently uses fee schedules for some OPD 
services, payment for other OPD services have remained under 
the retrospective costs-or-charges system, resulting in an 
extremely complex set of payment rules. For instance, payments 
for OPD services such as clinic and emergency room visits have 
been paid based on the lesser of hospital costs or charges. 
Certain surgeries carried out in OPDs, but which are also 
approved by Medicare to be provided in ASCs are paid the lower 
of costs, charges, or a blended payment that incorporates the 
ASC fee schedule amount (again, excluding physician charges). 
Payment for costs for certain radiology services and diagnostic 
procedures are based on a blended payment that includes, in 
part, the Medicare fee schedule for physician services. To add 
to the complexity, blended payment calculations may vary among 
different types of hospitals. Some OPD services are paid for 
exclusively according to a fee schedule (e.g., laboratory 
tests, physical therapy, prosthetics and orthotics, mammography 
screening, and some surgical dressings and supplies). Kidney 
dialysis services, which are often provided in specialized 
dialysis centers to which a PPS applies, are also paid under 
the dialysis PPS if provided in an OPD.
Beneficiary and hospital overpayment issues
    The complex arrangements under which Medicare's payments 
for OPD care have been determined has meant that, often, the 
final Medicare approved payment amount is not known until a 
hospital's annual cost reports are settled with Medicare, which 
might be long after services to any individual beneficiary are 
rendered. However, the Social Security Act permits providers to 
charge Medicare beneficiaries 20 percent of the reasonable and 
customary charges for part B-covered services. In the case of 
OPD services for which payment is based on the blended rate 
formula, the amount Medicare eventually would approve for the 
service might be considerably less than the hospital's charge. 
Thus, hospital OPDs have often billed beneficiaries at the time 
of service for 20 percent of charges rather than 20 percent of 
the amount computed and approved under Medicare's formulas. As 
a result, beneficiaries are ``overcharged,'' sometimes paying 
as much as 50 percent of the Medicare approved amount. The 
Medicare Payment Advisory Commission reported in 1999 that 
beneficiary coinsurance for OPD care represented about 47 
percent of the total Medicare payment hospitals received for 
outpatient services. ``Medigap'' insurance policies, which 
Medicare beneficiaries may purchase to pay Medicare's 
deductibles, copayments and coinsurance, relieve policyholders 
from these high charges, but the insurance industry has noted 
that the prices of their policies reflect such overcharges.
    When Medicare paid for hospital outpatient services under 
the blended rate formula, the program's share of the payment to 
the hospital was computed as if the beneficiary had paid only 
20 percent of the Medicare approved amount, including the 
limited fee schedule payment, instead of 20 percent of the 
hospital's charges, which generally disregarded the limitations 
of a fee schedule. Thus, the Medicare formula that assumed the 
beneficiary had paid a lesser amount resulted in a larger 
Medicare payment, and, consequently, hospitals were 
``overpaid'' by Medicare. This hospital overpayment situation 
was referred to as the ``formula-driven overpayment.''
The Balanced Budget Act (BBA) of 1997
    Despite implementation of certain fee schedules and across-
the-board reductions in payments, Medicare payments to hospital 
OPDs rose at an annual rate of over 12 percent from 1983 to 
1997 and increased from 7 percent to 20 percent as a share of 
all Medicare payments to hospitals. Many saw the patchwork 
payment arrangements for OPD care as fraught with disincentives 
for hospitals to provide care efficiently. Congress responded 
to these cost issues in BBA 1997. In order to end the complex 
and inequitable retrospective cost and charge-based 
reimbursement system, the law directed the Secretary of DHHS to 
implement the OPD PPS in 1999. It eliminated the formula-driven 
overpayment, effective at the start of fiscal year 1998, a move 
that resulted in an almost immediate reduction in Medicare 
payments to hospitals for those OPD services for which Medicare 
payments duplicated beneficiary payments. BBA 1997 also 
extended the across-the-board reductions of 5.8 percent for 
operating costs and 10 percent for capital costs through 1999.
     BBA 1997 established a procedure to bring beneficiary cost 
sharing for OPD services gradually into line at 20 percent of 
Medicare approved amounts by ``freezing'' the dollar amount 
hospitals may charge beneficiaries at 20 percent of the median 
of all hospital outpatient charges per procedure in 1996, 
updated to the time of implementation of the PPS. Thus, over 
time, as Medicare's payments under the new PPS rise according 
to an indexing formula, the ``frozen'' dollar amounts hospitals 
may charge beneficiaries will come to equal 20 percent of 
Medicare's PPS payments, and Medicare's payment will be 80 
percent of the full amount approved under the new system. 
However, for those services for which the spread between the 
median charge and the PPS approved amount is large, it could 
take many years before the beneficiary copayment is 20 percent 
of the amount specified in the PPS. The law allows hospitals 
voluntarily to limit beneficiary copayments to 20 percent and 
to disseminate information regarding their reduced beneficiary 
charges.
    On September 8, 1998, HCFA published proposed OPD PPS 
regulations for comment. Although the new PPS was then 
scheduled for implementation in 1999, HCFA delayed 
implementation until after the start of the year 2000 in order 
to accommodate resolution of ``Y2K'' data processing problems. 
HCFA extended the public comment period on the proposed 
regulations through July 30, 1999, and published final rules on 
April 7, 2000. Implementation began August 1, 2000.
Design and implementation of the outpatient department PPS
    Under the hospital outpatient PPS included in final rules 
published by HCFA, individual OPD services that are similar 
clinically and also in terms of resource utilization are 
arranged into groups according to an ambulatory payment 
classification (APC) system. The system includes 451 payment 
groups. A payment amount is established for each group and is 
the same for each service in the group. The payments cover 
hospital facility and nonphysician personnel costs. The labor 
component of a payment is adjusted to reflect regional 
variations.
    Services delivered in an OPD that are already covered by a 
PPS or fee schedule are excluded from the OPD PPS, but will 
continue to be paid under the existing applicable system. The 
OPD PPS does not apply for outpatient services provided to 
patients receiving services under part A in a skilled nursing 
facility (SNF) when the service is part of a patient's SNF plan 
of care and which is furnished by the hospital under an 
arrangement with the SNF.
    Hospitals excluded from the outpatient PPS altogether 
include certain facilities in Maryland that are paid under a 
special State program and critical access hospitals that are 
paid under a reasonable cost-based system according to rules in 
the Social Security Act.
Balanced Budget Refinement Act (BBRA) of 1999
    The proposed PPS regulations promulgated on September 8, 
1998, raised concerns about the adequacy of the payments under 
that system for certain kinds of services, patients, and 
hospitals. As a result, in BBRA 1999 (Public Law 106-113, 
November 19, 1999), Congress legislated several major changes 
to Medicare payments under the hospital OPD PPS. The BBRA 1999: 
(1) requires the Secretary of DHHS to provide payments (within 
specified limits, and on a budget neutral basis) over and above 
PPS payments for certain high cost (``outlier'') patients; (2) 
as a transition to the PPS, for 2-3 years, on a budget neutral 
basis, requires the Secretary of DHHS to provide ``passthrough 
payments'' to hospital OPDs above and beyond PPS payments for 
costs of certain ``current innovative'' and ``new, high cost'' 
devices, drugs, and biologicals; (3) limits the cost range of 
items or services that are included in any one PPS payment 
category so that the highest median (or mean) cost of an item 
or service in the group cannot be more than two times higher 
than the lowest median (or mean) cost for an item or service 
within the group; (4) requires the Secretary of DHHS to review 
the PPS groups and amounts annually and to update them as 
necessary; (5) as a transition to the PPS, through 2003, 
establishes ``transitional corridors'' which phase in 
reductions in aggregate Medicare payments individual hospitals 
experience due to the PPS; (6) provides special ``hold 
harmless'' payments until January 1, 2004, for small, rural 
hospitals to ensure that they receive no less under the 
outpatient PPS than they would have received in aggregate under 
the ``pre-BBA'' system and provides the same protection 
permanently for cancer hospitals; (7) caps beneficiary 
copayments for OPD care at the amount of the beneficiary 
deductible for inpatient care ($776 in 2000, and indexed for 
subsequent years); (8) requires that the pre-PPS payment base 
used as the budget neutrality benchmark for Medicare spending 
under the PPS include beneficiary coinsurance amounts as paid 
under the pre-PPS system (i.e., 20 percent of hospital 
charges); (9) requires coverage of the cost of implantable 
items; (10) allows the Secretary of DHHS to use either the mean 
or the median of hospital costs when establishing weights that 
determine payment amounts under the PPS; (11) extends across-
the-board reductions to payments for hospital operating costs 
and capital costs until implementation of the PPS; (12) allows 
reclassification of certain hospitals as urban or rural.
    The ``budget neutral'' requirement applicable to some of 
these changes means that the total cost of the Medicare Program 
is to be the same with the change as it would have been without 
the change. Thus, program cost increases would require payment 
adjustments elsewhere to offset those increases.
    According to HCFA data, on average, hospitals would receive 
4.6 percent more in payments under the new outpatient PPS, 
including the BBRA 1999 changes, than under the retrospective 
cost-based system.
    On December 8, 1999, the Congressional Budget Office (CBO) 
estimated that the provisions of BBRA 1999 applicable to 
Medicare OPD payments would add $11.2 billion in payments to 
hospitals over the period fiscal years 2000-2009.
Medicare payments to outpatient departments
    Table 2-22 summarizes the history of Medicare payments for 
hospital outpatient services from 1974 through 1998. (Starting 
in 1995, the data include only beneficiaries enrolled in 
traditional fee-for-service Medicare and exclude those who 
elected to enroll in a managed care plan.) The total number of 
beneficiaries enrolled in part B grew by about 31 percent 
during this time period, at an average annual rate of about 1 
percent, although disability caseload growth rates were higher 
than the rate of increase of elderly beneficiaries. The table 
documents the dramatic increase in hospital outpatient 
utilization and Medicare payments for OPD services since the 
early 1980s. Medicare payments increased 44-fold, from $323 
million in 1974 to $14.2 billion in 1998, with annual rates of 
increase averaging as high as 26.5 percent from 1974 to 1984. 
The substantial rates of increase in OPD payments per part B 
enrollee (from $14 in 1974 to $469 in 1998) reflect the 
increase in the volume of services provided in OPDs as well as 
growth in payments for those services under the retrospective 
cost-based payment system.
    Since 1983, hospital charges for OPD care for Medicare 
beneficiaries increased by 17.8 percent per year, on average. 
Medicare's payments for OPD services increased by 10.8 percent 
per year during that time period (table 2-22). The table shows 
that Medicare's payments as a percent of hospital charges for 
Medicare-covered OPD services has declined from nearly 70 
percent in 1983 to 28.1 percent in 1998. This declining ratio 
reflects primarily the high rates of increase in hospital 
charges and, to a lesser extent, limits on the rate of increase 
in Medicare's payments for OPD services due to fee schedules 
and blended payment formulas. It also reflects the increasing 
share of charges billed to beneficiaries. Payment systems under 
Medicare have included incentives for hospitals to increase 
their OPD charges. For example, since implementation in 1983 of 
the PPS for hospital inpatient care, some hospitals have 
shifted costs and charges from inpatient accounts to OPD 
accounts because they receive higher payments from Medicare 
under the outpatient payment formulas. In addition, because 
hospitals have routinely billed Medicare beneficiaries (or 
their Medigap plan) for 20 percent of charges, higher charges 
generate greater revenues from beneficiaries.

                  Ambulatory Surgical Center Services

    Services provided in an ambulatory surgical center (ASC) 
are paid under Medicare part B. An ASC is a facility where 
surgeries that do not require an inpatient hospital admission 
are performed. ASCs treat only patients who have already seen a 
health care provider and for whom surgery has been selected as 
an appropriate treatment. All ASCs must have at least one 
dedicated operating room and the equipment needed to perform 
surgery safely and to provide for recovery from anesthesia. 
Patients electing to have surgery in an ASC arrive for a 
scheduled appointment on the day of the procedure, have the 
surgery in an operating room, and recover under the care of the 
nursing staff before leaving for home.
    Medicare began covering ASC services in 1982 as a way to 
reduce costs for surgeries generally carried out on a hospital 
inpatient basis but that could be performed safely in a less 
costly outpatient setting. ASCs must meet certain conditions 
specified by Medicare in order to participate in the program. 
Some ASCs limit services to one type of surgery, such as 
ophthalmology, and others provide a variety of procedures, 
including gastroenterological, orthopedic, pain block, urology, 
podiatry, and ear, nose, and throat procedures. About half of 
all ASC procedures provided under Medicare in 1999 were related 
to cataracts or other types of eye surgery.
    Currently, over 2,500 procedures are included on the 
Medicare-approved list of ASC procedures. HCFA determines which 
procedures will constitute the ASC list on the basis of certain 
criteria related to the safety, appropriateness, and 
effectiveness of performing the procedure in an ASC setting.
    Table 2-23 shows the procedures most often carried out for 
Medicare beneficiaries in ASCs in 1999, the volume of those 
procedures for Medicare beneficiaries, and Medicare's total 
payments per procedure in that year.

Payment for ambulatory surgical centers
    From the start of Medicare coverage of ASC services, 
Medicare-based payments on a prospective payment fee schedule. 
This system was one of the first applications of a fee schedule 
for outpatient, or ambulatory, care.
    The two primary cost components of a surgical procedure are 
the physician's (or practitioner's) professional fees for 
performing the procedure and the costs associated with services 
furnished by the facility where the surgery is performed. 
Medicare pays ASCs for facility and nonphysician personnel 
costs incurred in connection with performing specific surgical 
procedures. Payments are based on ``reasonable overhead 
allowances.'' For example, items included among those covered 
by the allowances are nursing and technician services; 
supplies; drugs and biologicals; surgical dressings; 
housekeeping services; and use of the facility. As with other 
Medicare services, physician and certain practitioner fees are 
paid under a separate system.
    The Medicare-approved ASC procedures (about 2,500 
procedures) are consolidated into 8 payment groupings, each of 
which has 1 payment amount; that amount is adjusted for 
different geographic regions using the hospital wage index. 
After a beneficiary meets the part B annual deductible, 
Medicare pays ASCs 80 percent of the prospectively determined 
rate, and the beneficiary is responsible for 20 percent. In 
addition, Medicare and the beneficiary pay the physician or 
surgeon separately, with Medicare paying 80 percent of the 
approved amount under the physician fee schedule and the 
beneficiary being responsible for 20 percent.
Growth in services
    At the end of 1983, 1 year after Medicare began coverage of 
ASC care, 239 ASCs were approved to provide services for 
beneficiaries. Use of ASCs grew rapidly, and, at the end of 
1998, over 2,300 facilities participated in Medicare. From 1993 
through 1998, the volume of Medicare-covered ASC services 
provided grew from 1.06 million to 1.9 million. Medicare 
payments to ASCs increased at an average of 12.8 percent per 
year, from $495 million in 1993 to $902 million in 1998. Table 
2-24 shows the annual volume of ASC services and Medicare 
payments since 1993. Note that calendar year 1999 data do not 
include a full year of payments.

    Starting January 1, 1995, the Secretary of DHHS has been 
required to update ASC rates every 5 years based on a survey of 
the actual audited costs incurred by a representative sample of 
ASCs for a representative sample of procedures, and to increase 
annual payments in the intervening years by the Consumer Price 
Index for All Urban Consumers (CPI-U). However, for fiscal 
years 1998-2002, BBA 1997 reduced the annual update to the CPI-
U increase minus 2 percentage points. Because the fiscal year 
1999 adjustment would have been very small, HCFA made no 
adjustment for that year.
    Effective October 1, 1999 (for fiscal year 2000), payments 
for the eight categories into which all ASC procedures are 
grouped were updated by the CPI-U increase minus 2 percentage 
points. The increase was 0.8 percent. As of October 1, 1999, 
the base rates (prior to geographic adjustments) are:

Group 5..............................        683
----------------------------------------------------------------------------------------------------------------

Proposed changes to ASC Medicare payments
    On June 12, 1998, HCFA issued proposed rules which would 
make major changes in Medicare payments to ASCs. The major 
changes include replacing the eight payment groupings with an 
APC system comprised of 105 payment groups; updating underlying 
cost data using 1994 survey data updated to the present; and 
making additions to and deletions from the list of Medicare 
covered ASC procedures. Payments would range from $53 to $2,107 
and would be updated by the CPI-U annually on a calendar year 
basis. As of this writing, HCFA had received extensive comments 
on the proposed new APC groups and payments and estimates that 
final rules will be published in November 2000 for 
implementation in April 2001.
    Some surgical procedures approved for ASCs are also 
performed in hospital outpatient departments (OPDs). In 
designing the new OPD prospective payment system (PPS) and the 
new APC groups for ASC procedures, HCFA aimed to keep the 
grouping of surgical procedures comparable.
    BBRA 1999 did not address ASC payment rates, the APC 
system, or update procedures. However, it requires that, if the 
Secretary implements new rates based on the 1994 data (or any 
rates based on pre-99 Medicare cost survey data), those new 
rates must be phased in by basing payments one-third on the new 
rates in the first year, two-thirds in the second year, and 
fully in the third year.

                         Other Part B Services

Preventive services
    Screening mammograms.--Medicare covers an annual screening 
mammography for all women over age 40. Payment for a mammogram 
is based on the lesser of the actual charge, the amount 
established for the global procedure under Medicare's fee 
schedule, or the payment limit established for the procedure. 
The 2000 limit is $67.81.
    Screening Pap smears; pelvic exams.--Medicare authorizes 
coverage for a screening Pap smear and a screening pelvic exam 
once every 3 years; annual coverage is authorized for women at 
high risk. Payment is based on the clinical diagnostic 
laboratory fee schedule (see above). BBRA 1999 requires a 
minimum payment of $14.60 for Pap tests furnished in 2000.
     Prostate cancer screening tests.--BBA 1997 authorized 
coverage, beginning January 1, 2000, for an annual prostate 
cancer screening test for men over age 50. The test could 
consist of any (or all) of the following procedures: (1) a 
digital rectal exam; (2) a prostate-specific antigen blood 
test; and (3) after 2002, such other procedures as the 
Secretary finds appropriate for the purpose of early detection 
of prostate cancer.
    Colorectal screening.--BBA 1997 authorized coverage of and 
established frequency limits for colorectal cancer screening 
tests, effective January 1, 1998. A covered test is any of the 
following procedures furnished for the purpose of early 
detection of colorectal cancer: (1) screening fecal-occult 
blood test (for persons over 50, no more than annually); (2) 
screening flexible sigmoidoscopy (for persons over 50, no more 
than one every 4 years); (3) screening colonoscopy for high-
risk individuals (limited to one every 2 years); and (4) such 
other procedures as the Secretary finds appropriate for the 
purpose of early detection of colorectal cancer. Payment limits 
are established for the tests.
     BBA 1997 required the Secretary, within 90 days of 
enactment, to publish a determination on the coverage of 
screening barium enema. The Secretary determined that barium 
enema tests, as an alternative to either a screening flexible 
sigmoidoscopy or a screening colonoscopy, are to be covered in 
accordance with the same screening parameters specified for 
those tests.
    Diabetes screening tests.--Medicare's covered benefits 
include diabetes outpatient self-management training services. 
These services are defined as including educational and 
training services furnished to an individual with diabetes by a 
certified provider in an outpatient setting. They are covered 
only if the physician who is managing the individual's diabetic 
condition certifies that the services are needed under a 
comprehensive plan of care to ensure therapy compliance or to 
provide the individual with necessary skills and knowledge 
(including skills related to the self-administration of 
injectable drugs) to participate in the management of their own 
condition. Certified providers for these purposes are defined 
as physicians or other individuals or entities that, in 
addition to providing diabetes outpatient self-management 
training services, provide other items or services reimbursed 
by Medicare. Providers must meet quality standards established 
by the Secretary. They are deemed to meet the Secretary's 
standards if they meet standards originally established by the 
National Diabetes Advisory Board and subsequently revised by 
organizations that participated in the establishment of 
standards of the Board, or if they are recognized by an 
organization representing persons with diabetes as meeting 
standards for furnishing such services.
    In addition, Medicare covers blood glucose monitors and 
testing strips for type I or type II diabetics (without regard 
to a person's use of insulin, as determined under standards 
established by the Secretary in consultation with appropriate 
organizations). The national payment limit for testing strips 
was reduced by 10 percent beginning in 1998.
    Bone mass measurements.--Bone mass measurement is covered 
for the following high risk persons: an estrogen-deficient 
woman at clinical risk for osteoporosis; an individual with 
vertebral abnormalities; an individual receiving long-term 
glucocorticoid steroid therapy; an individual with primary 
hyperparathyroidism; or an individual being monitored to assess 
osteoporosis drug therapy. The Secretary is required to 
establish frequency limits.
Drugs/vaccines
    Medicare generally does not cover outpatient prescription 
drugs. Despite the general limitation, Medicare law 
specifically authorizes coverage for the following drugs:
  --Erythropoietin (EPO).--EPO for the treatment of anemia for 
        persons with chronic kidney failure.
  --Osteoporosis drugs.--Injectable drugs approved for the 
        treatment of postmenopausal osteoporosis provided to an 
        individual by a home health agency (HHA). A physician 
        must certify that the individual suffered a bone 
        fracture related to postmenopausal osteoporosis and 
        that the individual is unable to self-administer the 
        drug.
  --Oral cancer drugs.--Oral drugs used in cancer chemotherapy 
        when identical to drugs which would be covered if not 
        self-administered. Also covered are oral antinausea 
        drugs used as part of an anticancer chemotherapeutic 
        regimen, subject to specified conditions.
    Medicare also covers immunosuppressive drugs (such as 
cyclosporin) for 36 months following a covered organ 
transplant. BBRA 1999 provides for a temporary extension of the 
36-month limit on immunosuppressive drugs for persons otherwise 
exhausting their coverage in 2000-2004. In each calendar year, 
there will be an extension specified by the Secretary (as the 
number of months or partial months), applicable to persons who 
exhaust their benefits in that calendar year. The increase for 
persons exhausting their benefits in 2000 is 8 months. The 
minimum increase for persons exhausting their benefits in 2001 
is 8 months.
    By May 1, 2001, the Secretary may increase the number of 
months for the cohort exhausting their benefits in 2001. At the 
same time, the Secretary is also required to announce the 
additional months of benefits that will be available for the 
cohort exhausting their benefits in 2002. Similarly by May 1, 
2002 and 2003, the Secretary is required to announce the number 
of months that will apply to the cohort exhausting their 
benefits in the following year. Total expenditures over the 5-
year period are limited to $150 million.
    Medicare payment for drugs (not made on a cost or 
prospective payment basis) equals 95 percent of the average 
wholesale price. The Secretary is authorized to pay a 
dispensing fee to pharmacies. A special payment limit ($10 per 
1,000 units) applies for EPO.
    Medicare also pays for influenza virus vaccines (flu 
shots), pneumococcal pneumonia vaccine, and hepatitis B vaccine 
for persons at risk of contracting hepatitis B. Cost-sharing 
charges do not apply for pneumococcal pneumonia or influenza 
virus vaccines; cost-sharing charges do apply for hepatitis B 
vaccines.
Ambulance services
    Medicare pays for ambulance services provided certain 
conditions are met. The services must be medically necessary 
and other methods of transportation must be contraindicated. 
Ambulance services are currently paid on the basis of 
reasonable costs when such services are provided by a hospital; 
otherwise the payment is based on reasonable charge screens 
developed by individual carriers based on local billings (which 
may take a variety of forms). Based on these local billing 
methods, carriers develop screens for one or more of the 
following four main billing methods: (1) a single all inclusive 
charge reflecting all services, supplies, and mileage; (2) one 
charge reflecting all services and supplies, with separate 
charge for mileage; (3) one charge for all services and 
mileage, with separate charges for supplies; and (4) separate 
charges for services, mileage, and supplies. Within each broad 
payment method, additional distinctions are made based on 
whether the service is basic life support service or advanced 
life support, whether emergency or nonemergency transport was 
used, and whether specialized advanced life services were 
rendered.
    The Balanced Budget Act (BBA) of 1997 specified that the 
reasonable cost and charge limits would apply through 1999, 
with annual increases equal to the Consumer Price Index (CPI) 
minus 1.0 percentage point. A fee schedule was to be 
implemented in 2000. The aggregate amount of payments in 2000 
could not exceed what would be paid if the interim reductions 
remained in effect in that year. Annual increases in subsequent 
years would equal the CPI increase, except that in 2001 and 
2002 there would be a 1.0-percentage point reduction. 
Implementation of the fee schedule has been delayed until at 
least 2001.

                    END-STAGE RENAL DISEASE SERVICES

                                Coverage

    Medicare's End-Stage Renal Disease (ESRD) Program 
established in the Social Security Amendments of 1972, covers 
individuals who suffer from ESRD if they are: (1) fully insured 
for Old-Age and Survivors Insurance benefits; (2) entitled to 
monthly Social Security benefits; or (3) spouses or dependents 
of individuals described in (1) or (2). Such persons must be 
medically determined to be suffering from ESRD and must file an 
application for benefits.
    Benefits for qualified ESRD beneficiaries include all part 
A and part B medical items and services. ESRD beneficiaries are 
automatically enrolled in the part B portion of Medicare and 
must pay the monthly premium for such protection. 
Medicare+Choice (M+C) plans may provide ESRD benefits to the 
Medicare beneficiary who has been enrolled in an M+C 
organization and subsequently develops ESRD. However, 
beneficiaries with ESRD cannot enroll in an M+C plan.
    Table 2-25 shows expenditures, number of beneficiaries, and 
the average expenditure per person for all persons with ESRD 
(including the aged and disabled) from 1974 through 2005. Total 
projected program expenditures for the Medicare ESRD Program 
for fiscal year 2000 are estimated at $10.7 billion. In fiscal 
year 2000, there are an estimated 320,005 beneficiaries, 
including successful transplant patients and persons entitled 
to Medicare on the basis of disability who also have ESRD.

    When the ESRD Program was created, it was assumed that 
program enrollment would level out at about 90,000 enrollees by 
1995. That mark was passed several years ago, and no indication 
exists that enrollment will stabilize soon.
    Table 2-26 shows that new enrollment for all Medicare 
beneficiaries receiving ESRD services grew at an average annual 
rate of 4.6 percent from 1992 to 1998. Most of the growth in 
program participation is attributable to growth in the numbers 
of elderly people receiving services and growth in the numbers 
of more seriously ill people entering treatment. Table 2-26 
shows the greatest

rate of growth in program participation is in people over age 
75, at 10.2 percent, followed by people of ages 65-74 with a 
growth rate of 4.6 percent. The largest rate of growth in 
primary causes of people entering ESRD treatment was diabetes. 
People with diabetes frequently have multiple health problems, 
making treatment for renal failure more difficult.
    The rates of growth in older and sicker patients entering 
treatment for ESRD indicate a shift in physician practice 
patterns. In the past, most of these people would not have 
entered dialysis treatment because their age and severity of 
illness made successful treatment for renal failure less 
likely. Although the reasons that physicians have begun 
treating older and sicker patients are not precisely known, it 
is clear that these practice patterns have resulted, and will 
continue to result, in steady growth in the number of patients 
enrolling in Medicare's ESRD Program.
    ESRD is invariably fatal without treatment. Treatment for 
the disease takes two forms: transplantation and dialysis. 
Although the capability to perform transplants had existed 
since the 1950s, problems with rejection of transplanted organs 
limited its application as a treatment for renal failure. The 
1983 introduction of a powerful and effective immunosuppressive 
drug, cyclosporin, resulted in a dramatic increase in the 
number of transplants being performed and the success rate of 
transplantation.
    Table 2-27 indicates that a total of 13,272 kidney 
transplants were performed in Medicare-certified U.S. hospitals 
in 1998. Despite the significant increases in the number and 
success of kidney transplants, transplantation is not the 
treatment of choice for all ESRD patients. A chronic, severe 
shortage of kidneys available for transplantation now limits 
the number of patients who can receive transplants. Even absent 
a shortage of organs, some patients are not suitable candidates 
for transplants because of their age, severity of illness, or 
other complicating conditions. Finally, some ESRD patients do 
not want an organ transplant.
    For all of these reasons, dialysis is likely to remain the 
primary treatment for ESRD. Dialysis is an artificial method of 
performing the kidney's function of filtering blood to remove 
waste products. There are two types of dialysis: hemodialysis 
and peritoneal dialysis. In hemodialysis, still the most common 
form of dialysis, blood is removed from the body, filtered and 
cleansed through a dialyzer, sometimes called an artificial 
kidney machine, before being returned to the body. There are 
three types of peritoneal dialysis. Intermittent peritoneal 
dialysis and continuous cycling peritoneal dialysis (CCPD) 
requires the use of a machine while continuous ambulatory 
peritoneal dialysis does not require the use of a machine. 
Under peritoneal dialysis, filtering takes place inside the 
body by inserting dialysate fluid through a permanent surgical 
opening in the peritoneum (abdominal cavity). Toxins filter 
into the dialysate fluid and are then drained from the body 
through the surgical opening. Hemodialysis is usually performed 
three times a week, Intermittent peritoneal dialysis is 
performed once or twice a week, while continuous ambulatory 
peritoneal dialysis and CCPD require daily exchanges of 
dialysate fluid.

                             Reimbursement

    Medicare reimbursement for facility-based dialysis services 
provided by hospital-based and independent facilities are paid 
at prospectively determined rates for each dialysis treatment 
session. The rate, referred to as a composite rate, is derived 
from area wage differences and audited cost data adjusted for 
the national proportion of patients dialyzing at home versus in 
a facility. Adjustments are made to the composite rate for 
hospital-based dialysis facilities to reflect higher overhead 
costs.
    Beneficiaries electing home dialysis may choose either to 
receive dialysis equipment, supplies, and support services 
directly from the facility with which the beneficiary is 
associated (method I) or to make independent arrangements for 
equipment, supplies, and support services (method II). Under 
method I, the equipment, supplies, and support services are 
included in the facility's composite rate. Under method II, 
payments are made on the basis of reasonable charges and 
limited to 100 percent of the median hospital composite rate, 
except for patients on CCPD, in which case the limit is 130 
percent of the median hospital composite rate.
    Typically, neither the composite rate nor the reasonable 
charge payment for method II is routinely updated. To the 
extent that kidney transplantation services are inpatient 
hospital services, they are subject to the Medicare PPS. There 
is no specific update policy for reasonable costs of kidney 
acquisition, and 100 percent of reasonable costs is reimbursed. 
However, the composite rate for renal dialysis was updated in 
the Medicare Balanced Budget Refinement Act (BBRA) of 1999 
(Public Law 106-113). The act increased the composite rate by 
1.2 percent above the revised composite rate that was in effect 
in 1999. In fiscal year 2000, the composite rate is $132 for 
hospitals and $128 for freestanding facilities, following an 
additional increase of 1.2 percent in the rates in effect in 
1999.

                            MEDICARE+CHOICE

    Medicare has a longstanding history of offering its 
beneficiaries an alternative to the traditional fee-for-service 
program, beginning with private health plans contracts in the 
1970s and the Medicare Risk Contract Program in the 1980s. 
Then, in 1997, Congress passed BBA 1997 (Public Law 105-33), 
replacing the Risk Contract Program with the new 
Medicare+Choice (M+C) Program. The M+C Program established new 
rules for beneficiary and plan participation, along with a new 
payment methodology. In addition to controlling costs, the M+C 
Program was also designed to expand health plans to markets 
where access to managed care plans was limited or nonexistent 
and to offer new types of health plans. Most recently, Congress 
enacted legislation in order to address some of the issues 
arising from the BBA changes. BBRA 1999 (Public Law 106-33) 
changed the M+C Program in an effort to make it easier for 
Medicare beneficiaries and plans to participate in the program.
    By March 2000, M+C plans were available to about 72 percent 
of the 39 million Medicare beneficiaries, and about 16 percent 
of them chose to enroll in one of over 260 available M+C plans. 
The rapid growth rate of Medicare managed care enrollment in 
the 1990s has leveled off since the implementation of the M+C 
Program, and there was even a small decline in enrollment in 
2000. Despite this recent trend, the Congressional Budget 
Office (CBO) projects that M+C enrollment will almost double by 
2010, covering 31 percent of the Medicare population.
    In order to increase enrollment in Medicare managed care 
and to allow beneficiaries to better meet their health care 
needs, the M+C Program offers a diverse assortment of managed 
care plans. However achieving the goals of the M+C Program has 
been difficult, in part because the goal to control Medicare 
spending may have dampened interest by managed care entities in 
developing new markets, adding plan options, and in maintaining 
their current markets (see appendix E for further information 
about the M+C Program).

                            SELECTED ISSUES

       Utilization and Quality Control Peer Review Organizations

    The Medicare Utilization and Quality Control Peer Review 
Organization (PRO) Program was established by Congress under 
the Tax Equity and Fiscal Responsibility Act of 1982 (TEFRA, 
Public Law 97-35). Building on the former Professional 
Standards Review Organizations, the new PROs were charged by 
the 1982 law with reviewing services furnished to Medicare 
beneficiaries to determine if the services met professionally 
recognized standards of care, were medically necessary, and 
delivered in the most appropriate setting. Major changes were 
made to the PRO Program by the Social Security Act Amendments 
of 1983 (Public Law 98-21) and subsequent budget reconciliation 
acts. Most PRO review is focused on inpatient hospital care. 
However, there is limited PRO review of ambulatory surgery, 
postacute care, and services received from Medicare health 
maintenance organizations (HMOs).
    There are currently 53 PRO areas, incorporating the 50 
States and the territories. Organizations eligible to become 
PROs include physician-sponsored and physician-access 
organizations. In limited circumstances, Medicare fiscal 
intermediaries may also be eligible. Physician-sponsored 
organizations are composed of a substantial number of licensed 
physicians practicing in the PRO review area (for example, a 
medical society); physician access organizations are those 
which have available to them sufficient numbers of licensed 
physicians so that adequate review of medical services can be 
assured. Such organizations obtain PRO contracts from the 
Secretary of the U.S. Department of Health and Human Services 
(DHHS) through a competitive proposal process. Each 
organization's proposal is evaluated by HCFA for technical 
merit using specific criteria that are quantitatively valued. 
Priority is given to physician-sponsored organizations in the 
evaluation process. Effective October 1, 1999, all 53 PROs are 
operating under the sixth round of contracts (also referred to 
as the ``sixth scope of work'').
    In general, each PRO has a medical director and a staff of 
nurse reviewers (usually registered nurses), data technicians, 
and other support staff. In addition, each PRO has a board of 
directors, comprised of physicians and, generally, 
representatives from the State medical society, hospital 
association, and State medical specialty societies. The Omnibus 
Budget Reconciliation Act of 1986 (Public Law 99-509) requires 
each board to have a consumer representative. Because the board 
is usually consulted before a case is referred by the PRO to 
the DHHS inspector general for sanction, it assumes a major 
role in the PRO review process. Each PRO also has physician 
advisors who are consulted on cases in which there is a 
question regarding the nurse reviewer's referral. Only 
physician advisors can make initial determinations about 
services furnished or proposed to be furnished by another 
physician.
    PROs are paid by Medicare on a cost basis for their work. 
Outlays for PROs in fiscal year 1998 and in fiscal year 1999 
totaled $221.6 million and $213.4 million, respectively, with 
fiscal year 2000 outlays projected to be $484.9 million. 
Spending varies considerably from year to year depending on 
where the PROs are in their contract cycles. HCFA has indicated 
that actual outlays for fiscal year 2000 may be considerably 
lower than their current projection. Currently HCFA uses an 
allocation of 80 percent from the Medicare Hospital Insurance 
(HI) Trust Fund and 20 percent from the Supplementary Medical 
Insurance (SMI) Trust Fund to finance PRO activity.
    The PRO review process combines both utilization and 
quality review. In conducting utilization review, the PRO 
determines whether the services provided to a Medicare patient 
were necessary, reasonable, and appropriate to the setting in 
which they were provided. Although some utilization review is 
done on a prospective basis, the bulk of the reviews are done 
retrospectively. When a PRO determines that the services 
provided were unnecessary or inappropriate (or both), it issues 
a payment denial notice. The providers, the physicians, and the 
patient are given an opportunity to request reconsideration of 
the determination.
    The PRO checks for indications of poor quality of care as 
it is conducting utilization review. If a PRO reviewer detects 
a possible problem, further inquiry is made into the case. If 
it is determined that the care was of poor quality, the PRO 
must take steps to correct the problem. Specific sanctions are 
required if the PRO determines that the care was grossly 
substandard or if the PRO has found that the provider or the 
physician has a pattern of substandard care. In addition, under 
section 9403 of COBRA (Public Law 99-272), as amended by Public 
Law 101-239, authority exists for the PROs to deny payments for 
substandard quality care. This provision, however, has never 
been used.
    Each of the contracts between DHHS and the PROs must 
contain certain similar elements outlined in a document known 
as the Scope of Work. Under the third and previous scopes of 
work, PRO review was centered on case-by-case examinations of 
individual medical records, selected primarily on a sample 
basis. This approach to medical review was criticized by the 
Institute of Medicine and others as being costly, 
confrontational, and ineffective. The fourth scope of work 
incorporated a new review strategy called the Health Care 
Quality Improvement Initiative. PROs were required to use 
explicit, more nationally uniform criteria to examine patterns 
of care and outcomes using detailed clinical information on 
providers and patients. Instead of focusing on unusual 
deficiencies in care, the PROs were instructed to focus on 
persistent differences between actual indications of care and 
outcomes from those patterns of care and outcomes considered 
achievable. HCFA believed that this approach would encourage a 
continual improvement of medical practice in a way that would 
be viewed by physicians and providers as educational and not 
adversarial.
    The fifth scope of work similarly emphasized continuous 
quality improvement. Sample case reviews, other than those 
mandated by law (such as those relating to hospital notices of 
noncoverage and to beneficiary complaints) are no longer 
required. Instead, each PRO is required to conduct 4-18 quality 
improvement projects each year, depending on the size of their 
beneficiary populations.
    The sixth scope of work includes national and local quality 
improvement projects which address clinical priorities that are 
designed to improve the health status of Medicare 
beneficiaries. The intent is to increase the PRO's experience 
in collaborating with providers, practitioners, plans, 
purchasers, and beneficiaries to improve quality of care, test 
quality indicators and intervention strategies. One more 
controversial task has also been included in this most recent 
scope of work. PROs will implement a Payment Error Prevention 
Program to identify incorrect payments that result from billing 
errors. This is a cooperative program and does not include 
punitive actions. In the first year of the contract, PROs will 
implement review activities to identify unnecessary admissions 
and miscoded diagnosis-related group (DRG) assignments.

                            Secondary Payer

    Generally, Medicare is the ``primary payer,'' that is, it 
pays health claims first, with an individual's private or other 
public health insurance filling in some or all of Medicare's 
coverage gaps. However, in certain cases, the individual's 
other coverage pays first, while Medicare is the secondary 
payer. This phenomenon is referred to as the Medicare Secondary 
Payer Program.
    An employer (with 20 or more employees) is required to 
offer workers age 65 and older (and workers' spouses age 65 and 
older) the same group health insurance coverage as is made 
available to other employees. Workers have the option of 
accepting or rejecting the employer's coverage. If the worker 
accepts the coverage, the employer's plan is primary for the 
worker and/or spouse who is over age 65; Medicare becomes the 
secondary payer. Employers may not offer a plan that 
circumvents this provision.
    Similarly, a group health plan, offered by a large employer 
with 100 or more employees, is the primary payer for employees 
or their dependents who are on the Medicare Disability Program. 
The provision applies only to persons covered under the group 
health plan because the employee (generally the spouse of the 
disabled person) is in ``current employment status'' (i.e., is 
an employee or is treated as an employee by the employer).
    Secondary payer provisions also apply to ESRD individuals 
with employer group health plans (regardless of employer size). 
Prior to enactment of BBA 1997, the group health plan was the 
primary payer for 18 months for persons who became eligible for 
Medicare ESRD benefits. The employer's role as primary payer 
was limited to a maximum of 21 months (18 months plus the usual 
3-month waiting period for Medicare ESRD coverage). The BBA 
extended the application of the secondary payer provisions for 
the ESRD population from 18 to 30 months. This applies to items 
and services furnished on or after August 5, 1997 for periods 
beginning on or after February 5, 1997.
    Medicare is also the secondary payer when payment has been 
made, or can reasonably be expected to be made, under workers' 
compensation, automobile medical liability, all forms of no-
fault insurance, and all forms of liability insurance.
    The law authorizes a data match program which is intended 
to identify potential secondary payer situations. Medicare 
beneficiaries are matched against data contained in Social 
Security Administration and Internal Revenue Service files to 
identify cases in which a working beneficiary (or working 
spouse) may have employer-based health insurance coverage. 
Cases of previous incorrect Medicare payments are identified 
and recoveries are attempted. The BBA clarifies that recoveries 
can be initiated up to 3 years after the date the service was 
furnished. Further, recoveries may be made from third-party 
administrators except where such administrators cannot recover 
amounts from the employer or group health plan.
    Table 2-28 shows savings attributable to these Medicare 
secondary payer provisions. In fiscal year 1998, combined 
Medicare part A and B savings are estimated at $3.4 billion.

                    Supplementing Medicare Coverage

    Most beneficiaries depend on some form of private or public 
coverage to supplement their Medicare coverage. In 1996, only 
about 11.3 percent of beneficiaries relied solely on the 
traditional fee-for-service Medicare Program for protection 
against the costs of care; an additional 8.0 percent were 
enrolled in managed care organizations.
    The majority of the Medicare population (62.5 percent in 
1996) have private supplemental coverage. This private 
insurance protection may be obtained through a current or 
former employer (29.9 percent had such coverage in 1996). It 
may also be obtained through an individually-purchased policy, 
commonly referred to as a ``Medigap'' policy (28.4 percent had 
these plans in 1996). Some persons have both (4.2 percent in 
1996). In addition, a smaller percentage (about 16.5 percent in 
1996) have Medicaid coverage; a small group (1.7 percent in 
1996) have supplemental coverage from one of a variety of other 
public sources (such as the military) (table 2-29).

 Medigap
     Medigap policies offer coverage for Medicare's deductibles 
and coinsurance and for some services not covered by Medicare. 
Premiums vary widely by type of coverage, geographic location 
and whether premiums are community-rated or based on a 
beneficiary age. The Omnibus Budget Reconciliation Act of 1990 
provided for a standardization of Medigap policies; the 
intention was to enable consumers to better understand policy 
choices and to prevent marketing abuses. Implementing 
regulations generally limit the number of different types of 
Medigap plans that can be sold in a State to no more than 10 
standard benefit plans, known as ``plan A'' to ``plan J.'' The 
standardized plan A covers a core benefits package. Each of the 
other nine includes the core package plus a different 
combination of additional benefits. Only plan H, plan I, and 
plan J offer some drug coverage. Beneficiaries who purchased 
policies prior to the standardization requirement may renew 
these policies; however, policies issued after July 1992 must 
be one of the 10 standard plans.
    The law contains certain requirements which guarantee the 
ability of beneficiaries to enroll in Medigap plans under 
certain specified conditions. These guaranteed issue 
provisions, which are outlined below, were significantly 
expanded by the Balanced Budget Act of 1997.
    Six-month open enrollment.--Federal law establishes an open 
enrollment period for the aged. All insurers offering Medigap 
policies are required to offer open enrollment for 6 months 
from the date a person first enrolls in part B (generally when 
the enrollee turns 65). During this time an insurer cannot deny 
the issuance, or discriminate in the pricing of a policy 
because of an individual's medical history, health status, or 
claims experience This requirement is known as guaranteed open 
enrollment.
    There is no guaranteed open enrollment period for the 
nonaged disabled population. However, when a disabled person 
turns 65, that individual has the same open enrollment 
guarantee as other aged persons.
    Guaranteed issue.--The law guarantees issuance of specified 
Medigap policies (without an exclusion based on a preexisting 
condition) for certain persons whose previous supplementary 
coverage was terminated. Guaranteed issue also applies to 
certain persons who elect to try out an M+C plan but 
subsequently disenroll from such plan. In these cases, the 
insurer is prohibited from discriminating in the pricing of the 
Medigap policy on the basis of the individual's health status, 
claims experience, receipt of health care or medical condition. 
In general, this right must be exercised within 63 days of 
termination of other enrollment. In the case of terminating M+C 
plans, beneficiaries may elect to obtain the Medigap policy 
within 63 days of the notice of termination (rather than within 
63 days of the actual termination date).
    Certain requirements enable persons whose previous 
supplementary coverage was terminated to obtain Medigap 
coverage. These provisions may be particularly important to 
persons whose HMO terminates its participation in the M+C 
Program.
    The following groups of persons whose coverage is 
involuntarily terminated are guaranteed issue of any Medigap 
plan A, B, C, or F that is sold to new enrollees by Medigap 
issuers in the State:
 1. An individual enrolled under an employee benefits plan that 
        provides benefits supplementing Medicare and the plan 
        terminates or ceases to provide such benefits;
 2. A person enrolled with an M+C organization whose enrollment 
        is discontinued because the plan's certification is 
        terminated or the organization no longer provides the 
        plan in the individual's service area; the individual 
        moves outside of the entity's service area; or the 
        individual elects termination due to cause; and
 3. An individual enrolled under a Medigap policy if enrollment 
        ceases because: (i) of the bankruptcy or insolvency of 
        issuer and there is no provision under State law for 
        continuation of such coverage; (ii) the issuer violates 
        a material provision; or (iii) the issuer materially 
        misrepresented the policy's provisions.
    Guaranteed issue protections also extend to certain persons 
who elect to try out one of the options available under the M+C 
Program. An individual is guaranteed issuance of the Medigap 
policy in which he or she was previously enrolled if the 
individual terminated enrollment in a Medigap policy, enrolled 
in an M+C organization or similar entity, and terminated such 
enrollment within 12 months. (If the same policy is no longer 
sold by the insurer, the individual is guaranteed issuance of 
Medigap plans A, B, C, or F.) The guarantee only applies if the 
individual was never previously enrolled in an M+C or similar 
plan.
    One group of persons are guaranteed issuance of any Medigap 
policy sold in the State. These are persons who, when they 
first become entitled to Medicare at age 65, enroll in an M+C 
plan and disenroll from such plan within 12 months.
    Preexisting condition exclusions.--At the time insurers 
sell a Medigap policy, they are generally permitted to limit or 
exclude coverage for services related to a preexisting health 
condition; such preexisting condition exclusions cannot be 
imposed for more than 6 months. However, preexisting 
limitations may not be imposed in the following cases:
 1. During the first 6-month open enrollment period, if on the 
        date of application, the individual had health 
        insurance coverage meeting the definition of 
        ``creditable coverage'' under the Health Insurance 
        Portability and Accountability Act.
 2. An individual who has met the preexisting condition 
        limitation in one Medigap policy. The individual does 
        not have to meet the requirement under a new policy for 
        previously covered benefits; however, an insurer could 
        impose exclusions for newly covered benefits (for 
        example, for prescription drugs if not covered under 
        the previous policy).
 3. Any individual who falls into one of the qualifying events 
        categories discussed above under ``Guaranteed Issue.'' 
        These include persons whose previous coverage was 
        involuntarily terminated or persons who elect to try 
        out Medicare+Choice.
    The prohibition applies to persons who had coverage under a 
prior policy for at least 6 months. If the individual has less 
than 6 months prior coverage, the policy must reduce the 
preexisting exclusion by the amount of the prior coverage.
     The Balanced Budget Act (BBA) provides for high deductible 
Medigap plans. Specifically, it added 2 plan types to the list 
of 10 standard Medigap plans. These offer the benefit package 
of either plan F or plan J, except for the high deductible 
feature. The high deductible was set at $1,500 in 1998 and 
1999. In subsequent years, it is increased by the Consumer 
Price Index (CPI). The beneficiary would be responsible for 
expenses up to this amount. The 2000 deductible is $1,530.
 Employer-based policies
     In 1996, employer-based policies covered 34 percent of 
Medicare beneficiaries. Employer-based plans are typically more 
comprehensive than Medigap plans. Generally they are defined 
benefit plans which may overlap significantly with Medicare 
benefits. As a result, employers use a variety of approaches to 
coordinate their plans with Medicare (which is the primary 
payer for retirees). The costs of coverage are generally shared 
by the employer and retiree.
     In recent years, the percentage of employers offering 
retiree health coverage for their Medicare retirees has 
dropped. Between 1993 and 1999, the number of large firms (with 
500 or more employees) offering such coverage dropped from 40 
percent to 28 percent (Foster Higgins, 1999).
     In addition, many other employers are pursuing strategies 
to lower their liabilities for retiree health costs. Some 
employers are moving toward a defined contribution model for 
retiree health benefits. Others are using Medicare risk plans 
and other managed care organizations to deliver services to 
their retirees.
Impact of supplemental insurance on Medicare spending
    Medicare cost-sharing requirements are intended, in part, 
to encourage cost-conscious utilization. Insurance that 
supplements Medicare by covering deductibles and coinsurance 
removes these incentives. Many analyses have addressed how 
supplemental insurance affects beneficiaries' use of Medicare-
covered services and the cost of those services to Medicare. 
Typically, these studies have estimated that Medicare spending 
for beneficiaries with supplemental coverage are one-quarter to 
one-third higher, on average, than expenditures for 
beneficiaries without such coverage.
    A Physician Payment Review Commission analysis (Physician 
Payment Review Commission, 1997) of the Medicare Current 
Beneficiary Survey found a similar effect: Medicare 
expenditures for beneficiaries covered by supplemental 
insurance were about 30-percent higher than they were for those 
without such coverage. Subsequent analysis showed that the 
effect of secondary coverage on Medicare expenditures differs, 
depending on the source of coverage. Expenditures for 
beneficiaries having Medicare only are less than 75 percent of 
those for beneficiaries with Medigap. Spending for 
beneficiaries with employer-provided benefits average only 
about 10 percent less (chart 2-1).

  CHART 2-1. COMPARISON OF PROJECTED PER CAPITA SPENDING FOR AVERAGE 
       BENEFICIARIES, BY TYPE OF SUPPLEMENTAL INSURANCE AND YEAR 

    Note._These spending levels represent the expected 
differences in outlays after other factors have been taken into 
account.

    Source: Physician Payment Review Commission analysis of 
data from the 1993 and 1995 Medicare Current Beneficiary 
Survey. The sample size for 1993 was 11,285 and the sample size 
for 1995 was 13,261.

    Higher utilization among beneficiaries with supplemental 
insurance translates into increased Medicare costs because 
Medicare is the primary payer for those services. The Medicare 
Current Beneficiary Survey analysis found that per capita 
expenditures for Medicare beneficiaries with Medigap insurance 
were from $1,000 to $1,400 higher than those for beneficiaries 
with Medicare only. Per capita spending for beneficiaries with 
employer-provided supplements were from $700 to $900 higher 
than those for beneficiaries with no supplemental coverage.
    These results reflect the difference in spending by source 
of insurance, once other factors have been considered. High 
service use among beneficiaries with secondary insurance 
appears to be a consequence of having such insurance, 
presumably reflecting the reduced financial burden associated 
with using additional services.
Medicaid
    Some low-income aged and disabled Medicare beneficiaries 
are also eligible for full or partial coverage under Medicaid. 
Persons entitled to full Medicaid protection generally have all 
of their health care expenses met by a combination of Medicare 
and Medicaid. For these ``dual eligibles'' Medicare pays first 
for services both programs cover. Medicaid picks up Medicare 
cost-sharing charges and provides protection against the costs 
of services generally not covered by Medicare. Of particular 
importance for this population is coverage for prescription 
drugs and long-term care services.
    Several population groups are entitled to more limited 
Medicaid protection. These include qualified Medicare 
beneficiaries (QMBs), specified low-income Medicare 
beneficiaries (SLMBs), and certain qualified individuals. 
Persons meeting the qualifications for coverage under one of 
these categories, but not otherwise eligible for Medicaid, are 
not entitled to the regular Medicaid benefits package. Instead, 
they are entitled to have Medicaid make specified payments in 
their behalf.
    Qualified Medicare beneficiaries.--State Medicaid Programs 
are required to make Medicare cost-sharing assistance available 
to QMBs. A QMB is an aged or disabled Medicare beneficiary who 
has: (1) income at or below the Federal poverty line ($8,592 
for a single, $11,496 for a couple in 2000, including the $20 
per month disregard); and (2) resources below 200 percent of 
the resources limit set for the Supplemental Security Income 
(SSI) Program (the QMB resource limits are $4,000 for an 
individual and $6,000 for a couple). Certain items, such as an 
individual's home and household goods, are excluded from the 
calculation.
    Persons meeting the QMB definition are entitled to Medicare 
part A. Included is the relatively small group of aged persons 
who are not automatically entitled to part A coverage, but who 
have bought part A protection by paying a monthly premium. Not 
included are working disabled persons who have exhausted 
Medicare part A entitlement but who have extended their 
coverage by payment of a monthly premium.
    Medicaid is required to pay Medicare premiums and cost-
sharing charges for the QMB population as follows: (1) part B 
monthly premiums; (2) part A monthly premiums paid by the 
limited number of persons not automatically entitled to part A 
protection; (3) coinsurance and deductibles under part A and 
part B including the Medicare hospital deductible, the part B 
deductible, and the parts A and B coinsurance; and (4) 
coinsurance and deductibles that M+C plans charge their 
enrollees.
Payment of QMB benefits
    States are required to pay part A and part B premiums in 
full for the QMB population. They are also required to pay the 
requisite deductibles and coinsurance, though the actual amount 
of the payment may vary. State Medicaid Programs frequently 
have lower payment rates for services than those applicable 
under Medicare. Federal law permits States to either: (1) pay 
the full Medicare deductible and coinsurance amounts; or (2) 
only pay those amounts to the extent that the Medicare provider 
or supplier has not received the full Medicaid rate for the 
service.
    All States have buy-in agreements with the Secretary that 
allow them to enroll their QMB population in part B. Some 
States have also elected to include payment of part A premiums 
under their buy-in agreements. Payment of premiums under a buy-
in agreement is advantageous to the State because premiums paid 
through this method are not subject to delayed enrollment 
penalties which might otherwise be applicable in the case of 
delayed enrollment or reenrollment.
    The buy-in agreements for the QMB population are in 
addition to the traditional buy-in agreements that States have 
for other population groups. Under these traditional buy-in 
agreements, States enroll in Medicare part B persons who are 
eligible for both Medicare and Medicaid. As a minimum, States 
may limit buy-in coverage to persons receiving cash assistance; 
alternatively, they may add some or all categories of other 
persons who are eligible for both programs.
    Specified low-income Medicare beneficiaries.--States are 
also required to pay Medicare part B premiums for SLMBs. These 
are persons meeting the QMB criteria except that their income 
is slightly over the QMB limit. The SLMB income limit is 120 
percent of the Federal poverty line. In 2000 this is $10,260 
for a single and $13,740 for a couple (including the $20 per 
month disregard). Medicaid protection is limited to payment of 
the Medicare part B premiums, unless the beneficiary is 
otherwise eligible for Medicaid.
    Qualifying individuals.--BBA 1997 required State Medicaid 
Programs, effective January 1, 1998 through December 31, 2002, 
to pay part B premiums for beneficiaries with incomes up to 135 
percent of poverty. These persons are referred to as QI-1s. For 
Medicare beneficiaries with incomes between 135 and 175 percent 
of poverty, State Medicaid Programs are required to cover that 
portion of the Medicare part B premium attributable to the 
transfer of home health visits from part A to part B. These 
persons are referred to as QI-2s.
     The Federal Government will pay 100 percent of the costs 
associated with expanding Medicare part B premium assistance 
from 120 to 135 percent of poverty, as well as the extra 
premium cost attributable to the home health transfer for 
persons with incomes between 135 and 175 percent of poverty. To 
cover these costs, the Secretary is required to provide for 
allocations to States based on the sum of: (1) a State's number 
of Medicare beneficiaries with incomes between 135 and 175 
percent of poverty, and (2) twice the number of Medicare 
beneficiaries with incomes between 120 and 135 percent of 
poverty, relative to the sum for all eligible States. Total 
amounts available for allocations are $200 million for fiscal 
year 1998, $250 million for fiscal year 1999, $300 million for 
fiscal year 2000, $350 million for fiscal year 2001, and $400 
million for fiscal year 2002. The Federal matching rate for 
each participating State will be 100 percent up to the State's 
allocation. If a State exceeds its allocation, the matching 
rate on the excess is zero. Payments are to be made from 
Medicare part B for the costs of this program.
    Qualified disabled and working individuals (QDWIs).--
Medicaid is authorized to provide partial protection against 
Medicare part A premiums for QDWIs. QDWIs are persons who were 
previously entitled to Medicare on the basis of a disability, 
who lost their entitlement based on earnings from work, but who 
continue to have the disabling condition. Medicaid is required 
to pay the Medicare part A premium for such persons if their 
incomes are below 200 percent of the Federal poverty line, 
their resources are below 200 percent of the SSI limit, and 
they are not otherwise eligible for Medicaid. States are 
permitted to impose a premium, based on a sliding scale, for 
individuals between 150 and 200 percent of poverty.
Data
    As of July 1998, Medicare reported that there were 331,924 
Medicare part A beneficiaries for whom QMB payments for part A 
premiums were being made. As of the same date, States reported 
a total of 5,109,228 part B buy-ins of which 2,421,298 were 
separately identified as QMBs and 272,565 were separately 
identified as SLMBs (table 2-30). However, these numbers are 
low due to reporting problems. The QMB and SLMB numbers include 
persons who were eligible for the full Medicaid benefit 
package. No QMB-only or SLMB-only number is available. 
Nationwide there were 18 QDWIs in May 1997; this information is 
not broken down by State.

                      LEGISLATIVE HISTORY, 1980-99

    This section summarizes major Medicare legislation enacted 
into law since 1996. Previous editions of the Green Book review 
legislation enacted before 1996.
    The summary highlights major provisions; it is not a 
comprehensive list of all Medicare amendments. Included are 
provisions which had a significant budget impact, changed 
program benefits, modified beneficiary cost sharing, or 
involved major program reforms. Provisions involving policy 
changes are mentioned the first time they are incorporated in 
legislation, but not necessarily every time a modification is 
made. The descriptions include either the initial effective 
date of the provision or, in the case of budget savings 
provisions, the fiscal years for which cuts were specified.

Health Insurance Portability and Accountability Act of 1996, Public Law 
                                 104-1

     Added new criminal health care fraud provisions, 
strengthened existing civil and criminal fraud and abuse 
provisions and provided funding for new antifraud programs 
(generally effective on enactment or January 1, 1997).

          Balanced Budget Act (BBA) of 1997, Public Law 105-33

Hospitals
     Froze PPS hospital and PPS-exempt hospitals and units and 
limited updates for fiscal years 1999-2002. Established a PPS 
for inpatient rehabilitation hospitals, effective beginning in 
fiscal year 2001. Rebased capital payment rates and provided 
for additional reductions over the fiscal year 1997-2002 
period. Reduced the indirect medical education payment from the 
current 7.7 percent to 5.5 percent by fiscal year 2001 and 
reformed direct graduate medical education payments (generally 
effective on enactment or October 1, 1997).
 Skilled nursing facilities
     Provided for a phase in of a PPS that will pay a Federal 
per-diem rate for covered SNF services (generally effective 
July 1, 1998).
Home health
     Provided for the establishment of a PPS for home health 
services. Provided for a reduction in per-visit cost limits 
prior to the implementation of the PPS, clarified the 
definitions of part-time and intermittent care, and provided 
for a study of the definition of homebound. Provided for the 
transfer of some home health costs from part A to part B 
(prospective payment effective October 1, 1999, reduction in 
cost limits effective on enactment, definition clarification 
effective October 1, 1997, and transfer of costs effective 
January 1, 1998).
 Hospice
     Reduced the hospice payment update for each of fiscal 
years 1998-2002, and clarified the definition of hospice care 
(generally effective on enactment).
Physicians
     Provided for use of a single conversion factor; replaced 
the volume performance standard with the sustainable growth 
rate; provided for phased-in implementation of resource-based 
practice expenses; and permitted use of private contracts under 
specified conditions (generally effective January 1, 1998).
 Hospital outpatient departments
     Extended reductions in payments for outpatient hospital 
services paid on the basis of costs through December 1999 and 
established a PPS for hospital outpatient departments (OPDs) 
for covered services beginning in 1999 (generally effective on 
enactment).
Other providers
     Froze payments for laboratory services for fiscal years 
1998-2002; provided for establishment of a fee schedule in 2000 
for payment for ambulance services (generally effective on 
enactment).
 Beneficiary payments
     Permanently set the part B premium at 25 percent of 
program costs and expanded the premium assistance beginning in 
1998 available under the Specified Low-Income Medicare 
Beneficiary (SLMB) Program (effective on enactment).
 Prevention initiatives
     Authorized coverage for annual mammograms for all women 
over 40. Added coverage for screening pelvic exams, prostate 
cancer screening tests, colorectal cancer screening tests, 
diabetes self-management training services, and bone mass 
measurements for certain high-risk persons (generally effective 
in 1998, except prostate cancer screening effective 2000).
 Supplementary coverage
     Provided for guaranteed issuance of specified Medigap 
policies without a preexisting condition exclusion for certain 
continuously enrolled aged individuals (effective July 1, 
1998).
 Competitive bidding
     Provided for competitive bidding demonstrations for 
furnishing part B services (not including physicians services) 
(effective on enactment).
Commissions
     Established a 17-member National Advisory Commission on 
the Future of Medicare (with appointments to be made by 
December 1, 1997). Established the Medicare Payment Advisory 
Commission replacing the Prospective Payment Assessment 
Commission and the Physician Payment Review Commission (with 
appointments to be made by September 30, 1997).
 Medicare+Choice
     Established a new part C of Medicare called 
Medicare+Choice (M+C). This program is built on the existing 
Medicare Risk Contract Program which enabled beneficiaries to 
enroll, where available, in health maintenance organizations 
(HMOs) that contracted with the Medicare Program. The M+C 
Program expands, beginning in 1999, the private plan options 
that could contract with Medicare to other types of managed 
care organizations (for example, preferred provider 
organizations and provider-sponsored organizations), private 
fee-for-service plans, and, on a limited demonstration basis, 
high deductible plans (called medical savings account plans) 
offered in conjunction with medical savings accounts (effective 
on enactment).

    Balanced Budget Refinement Act (BBRA) of 1999 (Incorporated in 
      Consolidated Appropriations Act of 1999, Public Law 106-113)

Prospective payment system hospitals
    Froze the indirect medical education adjustment at 6.5 
percent through fiscal year 2000, reduced the adjustment to 
6.25 percent in fiscal year 2001 and to 5.5 percent in fiscal 
year 2002 and subsequent years. Froze the reduction in the DSH 
adjustment to 3 percent in fiscal year 2001; changed the 
reduction to 4 percent in fiscal year 2002. Changed the 
methodology for Medicare's direct graduate medical education 
payments to teaching hospitals to incorporate a national 
average amount calculated using fiscal year 1997 hospital-
specific per-resident amounts. Increased the number of years 
that would count as an initial period for child neurology 
residency training programs. Provided for the reclassification 
of certain counties and areas for the purposes of Medicare 
reimbursement.
PPS-exempt hospitals
    Adjusted the labor-related portion of the 75-percent cap to 
reflect the wage differences in the hospitals' area relative to 
the national average. Increased the amount of continuous bonus 
payments to eligible long-term care and psychiatric providers 
from 1 percent to 1.5 percent for cost reporting periods 
beginning on or after October 1, 2000 and before September 30, 
2001 and to 2 percent for cost reporting periods beginning on 
or after October 1, 2001 and before September 30, 2002. 
Required the Secretary to report on a discharge-based PPS for 
long-term care hospitals which would be implemented in a budget 
neutral fashion for cost reporting periods beginning on or 
after October 1, 2002. Required the Secretary to report on a 
per-diem-based PPS for psychiatric hospitals which would be 
implemented in a budget neutral fashion for cost reporting 
periods beginning on or after October 1, 2002. Required the 
Secretary base the PPS for inpatient rehabilitation hospitals 
on discharges and incorporate functional related groups as the 
basis for payment adjustments.
Rural providers
    Permitted reclassification of certain urban hospitals as 
rural hospitals. Updated existing criteria used to designate 
outlying rural counties as part of metropolitan statistical 
areas for the purposes of Medicare's hospital PPS. Changed 
certain requirements pertaining to Medicare's Critical Access 
Hospital Program. Extended the Medicare dependent hospital 
classification through fiscal year 2006. Permitted certain sole 
community hospitals to receive Medicare payments based on their 
hospital specific fiscal year 1996 costs. Increased the target 
amount for SCHs by the full market basket amount for discharges 
occurring in fiscal year 2001.
Skilled nursing facilities
    Increased, from April 1, 2000, until October 1, 2000, per-
diem payments by 20 percent for 15 resource utilization groups 
(RUGs) under the PPS. Permitted payment under the Federal PPS 
rate for agencies for which it is more advantageous than under 
the transition rates. Provided for payment beyond the 
designated PPS rate for ambulance services for dialysis 
patients and for specific chemotherapy items and services, 
radioisotope services, and prosthetic devices. Until October 1, 
2001, fixed PPS per-diem rates at 50 percent of the facility-
specific rate and 50 percent of the Federal rate for facilities 
in which 60 percent of the patients are immunocompromised.
Home health agencies
    Delayed the 15-percent reduction in home health payments 
until 12 months after implementation of the PPS but, within 6 
months of implementation, required the Secretary to assess the 
need for any reductions. Increased per-beneficiary limits by 2 
percent for older agencies; excluded DME from consolidated 
billing, and provided $10 per beneficiary to offset HHA costs 
for collecting outcome and assessment information set (OASIS) 
data.
Hospice
    Increased payment rates otherwise in effect under the 
hospice PPS for fiscal year 2001 by 0.5 percent and for fiscal 
year 2002 by 0.75 percent, provided that these increases are 
not to be included in the base on which subsequent increases 
will be computed.
Physicians
    Made technical changes to limit oscillations in the annual 
update to the conversion factor beginning in 2001 and provided 
that the sustainable growth rate is calculated on a calendar 
year basis. Required the Secretary, in determining practice 
expense relative values, to establish by regulation a process 
under which the Secretary would accept for use and would use, 
to the maximum extent practicable and consistent with sound 
data practices, data collected by outside organizations and 
entities.
Hospital outpatient departments
    Made seven major changes to Medicare payments under the 
hospital OPD PPS: (1) required the Secretary of the U.S. 
Department of Health and Human Services (DHHS) to provide 
payments (within specified limits, and on a budget neutral 
basis) over and above PPS payments for certain high cost 
(``outlier'') patients; (2) as a transition to the PPS, for 2-3 
years, on a budget neutral basis, required the Secretary of 
DHHS to provide ``passthrough payments'' to hospital OPDs above 
and beyond PPS payments for costs of certain ``current 
innovative'' and ``new, high cost'' devices, drugs, and 
biologicals; (3) limited the cost range of items or services 
that are included in any one PPS category and required the 
Secretary to review the PPS groups and amounts annually and to 
update them as necessary; (4) as a transition to the PPS, 
through 2003, limited the reduction in Medicare payments 
individual hospitals experience due to the PPS; (5) provided 
special payments until 2004 for small, rural hospitals to 
ensure that they receive no less under the outpatient PPS than 
they would have received under the prior system and provided 
the same protection permanently for cancer hospitals; (6) 
limited beneficiary copayments for outpatient care to no more 
than the amount of the beneficiary deductible for inpatient 
care; and (7) required that the pre-PPS payment base used as 
the budget neutrality benchmark for the PPS include beneficiary 
coinsurance amounts as paid under the pre-PPS system (i.e., 20 
percent of hospital charges).
Therapy services
    Suspended for 2 years (2001 and 2002) application of the 
caps on physical therapy and occupational therapy services.
Pap smears
    Set the minimum payment for the test component of a Pap 
smear at $14.60.
Immunosuppressive drugs
    Extended the 36-month limit on coverage of 
immunosuppressive drugs for persons exhausting their coverage 
in 2000-2004. Set the increase for persons exhausting benefits 
in 2000 at 8 months, and limited total expenditures to $150 
million over the 5 years.
Studies
    Required a number of studies including a Medicare Payment 
Advisory Commission comprehensive study of the regulatory 
burdens placed on all classes of providers under fee-for-
service Medicare and the associated costs. Required GAO to 
conduct a study of Medigap policies.
Medicare+Choice
    Contained several provisions designed to facilitate the 
implementation of M+C. Changed the phase in of the new risk 
adjustment payment methodology based on health status to a 
blend of 10 percent new health status method/90 percent old 
demographic method in 2000 and 2001, and not more than 20 
percent health status in 2002. Provided for payment of a new 
entry bonus of 5 percent of the monthly M+C payment rate in the 
first 12 months and 3 percent in the subsequent 12 months to 
organizations that offer a plan in a payment area without an 
M+C plan since 1997, or in an area where all organizations 
announced withdrawal as of January 1, 2000. Reduced the 
exclusion period from 5 years to 2 years for organizations 
seeking to reenter the M+C Program after withdrawing. Allowed 
organizations to vary premiums, benefits, and cost sharing 
across individuals enrolled in the plan so long as these are 
uniform within segments comprising one or more M+C payment 
areas. Provided for submission of adjusted community rates by 
July 1 instead of May 1. Provided that the aggregate amount of 
user fees collected would be based on the number of M+C 
beneficiaries in plans compared to the total number of 
beneficiaries.
    Delayed implementation of the Medicare+Choice Competitive 
Bidding Demonstration Project.

CBO SAVINGS AND REVENUE ESTIMATES FOR BUDGET RECONCILIATION AND RELATED 
                             ACTS, 1981-99

    Table 2-31 shows estimates of savings and revenue increases 
for budget reconciliation legislation enacted from 1981 to 1997 
and spending increases enacted in 1999. These estimates were 
made at the time of enactment by the Congressional Budget 
Office (CBO). It should be noted that the estimates are 
compared with the CBO budget baseline in effect at the time. 
The savings from the various reconciliation bills cannot be 
added together.
