Hospitals provide a range of outpatient health care services in different settings (such as outpatient departments, clinics, and ambulatory surgery centers) under various organizational and ownership arrangements. These outpatient facilities may be located on or off the hospital campus or in satellite facilities. A range of different health care professionals and practitioners treat patients in these settings. Simply, the way that the various health care services are categorized, covered, and reimbursed will vary by payor. Under the Medicaid program, outpatient hospital (OPH) services are a mandatory benefit for most beneficiaries. In FY2006, expenditures for outpatient hospital services totaled roughly $11.5 billion, or 3.9% of total Medicaid spending (about $299.0 billion). Current Medicaid regulations broadly define hospital outpatient services to include preventive, diagnostic, therapeutic, rehabilitative, or palliative services provided under the direction of a physician or a dentist in the hospital. States use a number of different reimbursement methods for different types of services provided in outpatient hospital departments and clinics. For example, some states pay a flat per-visit rate for a clinic visit, use a fee schedule for surgery, and pay on a cost-basis for certain specialized services. In 2002, about half of the states based their OPH reimbursement largely on hospital-specific costs (e.g., actual costs or prospective rates based on historic costs with a limit on annual increases, or paid a fixed percentage of actual costs). In addition, more recent 2006 data indicate that 11 states used Medicare groupings and/or methodologies for determining reimbursement rates for some OPH services. Finally, in general, Medicaid payments for institutional services (e.g., hospitals and nursing homes) cannot, in the aggregate, and within three provider categories (state government, non-state government, and private), exceed a reasonable estimate of what Medicare would pay for the same services. This is called the Medicaid upper payment limit (UPL) rule. This UPL rule is applied separately to inpatient and outpatient facility care; no UPL rule applies to professional services. Under the Medicare program, hospitals are paid for certain services provided to outpatients through Medicare's outpatient prospective payment system (OPPS), which uses a fixed payment rate that reflects expected resource use for specific ambulatory patient classifications or APCs (which groups sets of hospital outpatient diagnoses and procedure codes into broader categories, which are reimbursed by specified Medicare payment amounts). Generally, the OPPS payments cover the facility costs associated with a procedure performed in an outpatient department. Other services are provided by hospitals in outpatient settings that are not paid under OPPS. These include professional services provided by physicians and health practitioners (e.g., psychologists, social workers, physical therapists) paid under the physician fee schedule, as well as clinical diagnostic services, ambulance services, dialysis services, and most durable medical equipment, all paid using different methods. Off-campus or satellite outpatient facilities that meet certain provider-based requirements are treated as part of a hospital, not freestanding, independent entities, and are paid under alternative payment methods. These determinations affect Medicare (and Medicaid) payment amounts, the scope of benefits available to a beneficiary (in or at the facility), and/or beneficiary out-of-pocket liability. The proposed rule (72 Federal Register 55158, September 28, 2007) would limit the definition and scope of Medicaid outpatient services in a hospital clinic, hospital facility, or rural health clinic. Federally reimbursable Medicaid outpatient services would include only those facility services (1) that Medicare would pay for under its OPPS or recognized by Medicare as an OPH service under an alternate payment methodology; (2) provided by an outpatient hospital facility, including only those entities that meet standards for provider-based status as a department of an outpatient hospital as defined in Medicare rules; and (3) not covered under the scope of any other Medicaid benefit category. Under the proposed rule, the UPL for privately operated outpatient hospital facilities would remain tied to a reasonable estimate of what Medicare would pay for the same services. However, the calculations used to demonstrate compliance with this UPL would be required to include only services that (1) may be covered under the new Medicaid outpatient services definition and (2) are reimbursable under Medicare (i.e., appear on outpatient-specific Medicare cost report worksheets). With respect to the second criterion, states would be required to base this UPL calculation on the hospital-specific ratios (cost-to-charge or payment-to-charge) as reported in the most recently filed Medicare hospital cost report, or an equivalent state cost report. A different UPL calculation would apply to privately operated clinics that are not part of a hospital. For these entities, states would choose one of two UPL methods: (1) a defined percentage, not to exceed 100% of what Medicare pays under the non-facility fee schedule, or (2) a comparison by individual procedure code of Medicare payment amounts for equivalent Medicaid services when Medicaid reimbursements are based on a specific fee schedule or encounter rate. For this second method, the calculation may be conducted in the aggregate for clinic type or by specific facilities (for end stage renal disease, ambulatory surgical centers, etc.). Services for which the Medicaid statute defines a separate UPL (e.g., clinical diagnostic laboratory services ) must be excluded from this clinic UPL. Finally, for dentists providing services in such clinics, the UPL calculation may include payment amounts that Medicaid would otherwise pay outside the facility. CMS stated that it cannot determine the fiscal impact of this proposed rule because of a lack of available data. However, CMS believes this rule would not significantly alter current practices in most states. In the preamble to this rule, CMS indicated it had approved outpatient hospital reimbursement methods submitted by 32 states over a four-year period, and only 1 state (not named) used methods that may be minimally affected by the rule. In early 2008, CBO estimated that this rule would reduce federal Medicaid outlays by $0.3 billion over 5 years and $0.7 billion over 10 years. A 2008 congressional report indicated that this rule would result in a loss of roughly $2.1 billion over the next five years in four states that could provide such estimates. Eighteen other states reported that there might be a financial impact, but could not provide a dollar estimate. CMS argues that the current definition of outpatient hospital services in regulations overlaps with other covered Medicaid benefits, so that identical services are sometimes paid a higher amount under the outpatient hospital benefit than would otherwise be available under other Medicaid benefit categories. CMS also finds the current definition to be overly broad, including services over which outpatient hospital departments have no oversight or control, and can include services outside the normal responsibility of outpatient hospital departments (e.g., non-facility physician and practitioner services, and non-traditional OPH services such as school-based and rehabilitation services). CMS noted that some states may need to move services that would no longer meet the new definition of outpatient hospital services to other appropriate coverage categories and payment methodologies under the state plan. CMS noted that a number of states requested that the agency clarify in regulation the requirements for calculating Medicare comparable UPLs on outpatient and clinic services. In calculating the UPL for hospital and clinic services in private facilities, CMS argued that the current regulation does not indicate how this estimate should be made, and it does not address treatment of services that are not comparable to those provided under Medicare (e.g., dental services). In addition, CMS indicated that some states have used their own state-specific hospital cost reports to determine compliance with this UPL and such reports may not represent finalized data or accurately reflect Medicare payment and/or charge ratios. CMS considers the Medicare cost reports or equivalent state cost reports to be a more accurate measure of this UPL. CMS received a number of comments on this proposed rule. Examples of some of those comments are summarized here. First, under current law, states make certain supplemental payments to selected providers that treat a large number of low-income and Medicaid patients for their uncompensated hospital services. Federal statute establishes a ceiling on such "disproportionate share hospital," or DSH, allotments for each state. States must identify hospitals qualifying as DSH hospitals and must specify DSH payment formulas. Opponents argue that the proposed rule's new definition of OPH services would exclude many of the costs that states now consider in calculating DSH payments, which could in turn limit such payments to hospitals. Other arguments highlight the potential negative impact of the proposed rule on Medicaid children and children's hospitals. First, one argument notes that while Medicare serves as a benchmark for this new rule, Medicare covers very few children and would not cover preventive and screening services provided under "Early and Periodic Screening, Diagnostic, and Treatment Services" (EPSDT), a mandatory Medicaid benefit for most Medicaid beneficiaries under the age of 21. The commenter also concludes that the regulation directly contravenes the Medicaid EPSDT provision by excluding federal matching dollars for OPH programs that provide required EPSDT diagnostic and treatment services that may not be covered under Medicare. More generally, other commenters observed that the OPH services no longer permitted under this rule may continue to be provided by hospitals in other ways, albeit at a reduced payment rate. Second, with respect to the rule's requirement to use Medicare's cost-to-charge and payment-to-charge ratios in calculating the UPL for private providers, other opponents of the rule argue that hospitals with a significantly different patient mix from Medicare, such as children's hospitals, would not have their costs appropriately accounted for in the new UPL. Children's hospitals that submit low-volume cost reports and other hospitals with nontraditional charge structures may not readily be able to comply with the new UPL requirements. Other commenters raise additional concerns that the new definition of OPH services under the proposed rule will exclude coverage of various services previously offered through this benefit, which may limit beneficiary access to such services in some states. OPH services are a mandatory benefit under Medicaid and are likely to include, for example, physical therapy (PT) for outpatients. While Medicare also covers PT in OPH settings, these services are not reimbursed under the OPPS and thus would be excluded from the new definition of OPH services for Medicaid. Outside of EPSDT, PT may be otherwise available under Medicaid, but as an optional benefit. Data from 2005 show that eight states do not offer this optional PT benefit. Concerns about the proposed calculations for demonstrating compliance with the UPL for private facilities were also expressed. One comment letter noted that it was unclear whether compliance with the UPL for OPH services must be demonstrated in the aggregate, for each individual provider, and/or at the cost center level. Different descriptions of the proposed UPL calculations in both the preamble and the new regulatory language in the proposed rule contributed to this confusion. Several commenters argued that specific provisions in the proposed OPH rule violate the one-year moratorium in P.L. 110-28 on implementation or further action on two other rules: (1) the final rule establishing Medicaid cost limits for public providers (72 Federal Register 29748, May 29, 2007) and (2) the proposed rule on graduate medical education (GME) expenditures under Medicaid (72 Federal Register 28930, May 23, 2007). Specifically, the proposed OPH services rule incorporates the new definition of hospital categories that was adopted in the final rule regarding cost limits on public providers, which eliminates references to provider ownership status; commenters argue that including this language directly contravenes the moratorium on implementing any provision of the public provider rule. Commenters also argue that the OPH services rule violates the moratorium on the GME rule, because the proposed UPL calculations use Medicare cost report calculations that have excluded GME costs. Other procedural concerns have been noted. Specifically, commenters objected that the proposed rule was more than a clarification of existing policy and that implementation of the rule would impose substantial administrative changes on state Medicaid programs and significantly decrease hospital revenues. CMS's determination that no regulatory impact analysis was necessary was considered by commenters to be inaccurate and did not constitute appropriate notification or provide sufficient data to the affected parties. This shortcoming was compounded by the length of the comment period (30 days and not 60 days), which also undermined the ability of interested parties to submit informed comments. Certain commenters raised substantive technical objections to the proposed UPL methodologies. For instance, a UPL calculated using the Medicare payment-to-charge ratio established from the cost report worksheets referenced in the proposed rule would not include the beneficiary co-payment and coinsurance amounts, which constitute at least 20% of Medicare's allowed payment amounts under OPPS. The other UPL calculation that would potentially limit Medicaid payments for OPH services to costs was challenged as well. The statement by CMS that the cost-to-charge ratio would produce the highest amount that CMS would pay for hospital outpatient services was seen as inaccurate, because under the Medicare OPPS, efficient hospitals are allowed to retain APC-based payments above service costs. Also, CMS did not address the application of this proposed rule to critical access hospitals, which receive Medicare payments based on 101% of their allowable costs. Finally, the proposed methodology to establish the UPL for freestanding clinic services was criticized, because it did not recognize the prevalence of cost-based reimbursement for private clinic services by Medicaid and would result in significant access problems for these services. The final rule, issued on November 7, 2008 (73 Federal Register 66187), made a major change to the proposed rule. As noted above, commenters on the proposed OPH rule argued that, because it incorporated the new definition of hospital categories adopted in the final rule regarding cost limits on government providers, this rule violated the moratorium on implementing any provision of the rule on cost limits for government providers. In light of these views, and given this moratorium, CMS elected to exclude from its final OPH rule the proposed regulatory language delineating methods for demonstrating compliance with the Medicaid upper payment limit on outpatient hospital and clinic services provided in privately operated facilities. CMS did adopt the proposed outpatient hospital service definition effective December 8, 2008. As of January 26, 2009, 12 states have submitted pending state plan amendments to comply with the new final regulation. During the 110 th Congress, legislation to delay implementation of the OPH services rule, as well as other recent Medicaid regulations, was introduced (e.g., S. 2460 and S. 2819 ). H.R. 5613 , as passed by the House, and H.R. 2642 (a war supplemental spending bill), subsequently passed by the Senate, would provide for a moratorium until April 1, 2009, on any administrative action with respect to the OPH services rule, if that action is more restrictive than policies in place on September 27, 2007 (the day preceding the publication of the proposed OPH services rule). However, on June 19, the House passed an amendment to the Senate-passed version of H.R. 2642 that did not include a moratorium on the OPH services rule. Subsequently, on June 26, the Senate agreed to the House version that excluded such a moratorium on this rule. On June 30, this bill became P.L. 110-252 . Subsequent legislation (e.g., H.R. 7219 , H.R. 7241 , S. 3656 ) would also establish a moratorium on the OPH services rule. The American Recovery and Reinvestment Act of 2009 ( P.L. 111-5 ) prohibits the Secretary of Health and Human Services from taking any action until after June 30, 2009 (through regulation, regulatory guidance, use of federal payment audit procedures, or other administrative action, policy, or practice, including a Medical Assistance Manual transmittal or state Medicaid director letter), to implement the final regulation covering outpatient hospital facility services. The Congressional Budget Office and the Joint Committee on Taxation estimate that this moratorium, in combination with extended moratoria on other Medicaid rules (affecting case management services, school-based services, and provider taxes) and a Sense of the Congress that the Secretary should not promulgate final rules for three additional regulations (affecting cost limits for public providers, graduate medical education and rehabilitative services), would increase federal spending by $105 million in FY2009. Separate cost estimates for the provisions affecting each individual regulation were not provided. On May 6, 2009, CMS issued a proposed rule (74 Federal Register 21292) that would rescind the Medicaid outpatient services rule in its entirety, among other actions. CMS would reinstate the prior regulatory definition of outpatient hospital services at 42 CFR 440.20 that existed before their rulemaking process was initiated; it would also remove provisions that defined Medicaid outpatient services as those recognized under Medicare's OPPS (or an alternative payment methodology) and those furnished by an hospital outpatient department or facility. The requirement that Medicaid's definition of outpatient services would exclude services covered and reimbursed under the scope of another Medicaid service category under the state plan would also be eliminated. Finally, CMS would withdraw the provisions that provided regulatory guidance on the calculation of the UPL for outpatient hospital and clinic services. Public comments on this proposed rule will be accepted until June 1, 2009.

Summary:
On September 28, 2007, a proposed Medicaid rule was published that would (1) change the definition of outpatient hospital and rural health clinic services and (2) change the methods states must use to demonstrate compliance with the federal upper payment limit on outpatient hospital services provided in private outpatient facilities. A number of groups have expressed concern that this rule will have a significant negative impact on coverage of certain services, which may harm Medicaid beneficiaries. On November 7, 2008, the Centers for Medicare and Medicaid Services (CMS) issued a final Medicaid rule on outpatient hospital services that excluded the proposed regulatory language delineating methods for demonstrating compliance with the upper payment limit on outpatient hospital services provided in private outpatient facilities. The effective date of the regulation had been December 8, 2008. As of January 26, 2009, 12 states have submitted state plan amendments in response to the regulation. The American Recovery and Reinvestment Act of 2009 (P.L. 111-5) prohibits the Secretary of Health and Human Services from taking any action until after June 30, 2009 (through regulation, regulatory guidance, use of federal payment audit procedures, or other administrative action, policy, or practice, including a Medical Assistance Manual transmittal or state Medicaid director letter), to implement the final regulation covering outpatient hospital facility services. On May 6, 2009, CMS issued a proposed rule that, among other actions, rescinded the final Medicaid rule defining outpatient services. Public comments on this proposal will be accepted until June 1, 2009.
