What GAO Found

Unlike beneficiaries seen at teaching hospitals paid under Medicare's prospective payment systems (PPS) in 2012, nearly all beneficiaries seen at PPS-exempt cancer hospitals (PCH)—a group of 11 facilities having met certain statutory criteria—had a diagnosis of cancer. However, the health status of Medicare beneficiaries with cancer who were treated at PCHs and PPS teaching hospitals was not markedly different. The average risk score—a Medicare measure of overall health—of cancer beneficiaries at PCHs was comparable to that of cancer beneficiaries at PPS teaching hospitals both in the inpatient and outpatient settings. This similarity was also evident in comparing the relative case mix—an indicator of the cost and resource intensity of care—for cancer beneficiaries admitted to PCHs and PPS teaching hospitals.

Compared with how PPS teaching hospitals are paid, the methodologies for paying PCHs provide little incentive for efficiency. Under a PPS, Medicare pays hospitals a predetermined amount based on the clinical classification of each service they provide. PPS hospitals can retain any cost savings relative to their Medicare payments. In contrast, as required by the exemption, Medicare pays PCHs for inpatient services based on their reported costs, subject to an upper limit, as well as potential add-on payments. For outpatient care, Medicare pays PCHs at service-specific rates with an upward payment adjustment based on reported costs.

In 2012, Medicare payments—both inpatient and outpatient—were substantially higher at PCHs than at PPS teaching hospitals in the same geographic area for beneficiaries with the same diagnoses or services. GAO estimated that PCHs received, on average, about 42 percent more in Medicare inpatient payments per discharge than what Medicare would have paid a local PPS teaching hospital to treat cancer beneficiaries with the same level of complexity. Similarly, Medicare outpatient payment adjustments to PCHs resulted in overall payments that were about 37 percent higher, on average, than payments Medicare would have made to PPS teaching hospitals for the same set of services. The estimated differences in Medicare payments varied greatly across PCHs. Furthermore, GAO found no association between the proportion of Medicare payments for cancer patient care and Medicare profit margins at PPS teaching hospitals, indicating that the PPS or an alternative payment methodology may be reasonable for cancer care.

Because Medicare's payment methodology for PCHs lacks strong incentives for cost containment, it has the potential to result in substantially higher total Medicare expenditures. If, in 2012, PCH beneficiaries had received inpatient and outpatient services at nearby PPS teaching hospitals—and the forgone outpatient adjustments were returned to the Supplementary Medical Insurance Trust Fund—Medicare may have realized annual savings of almost $0.5 billion. Until Medicare pays PCHs to at least, in part, encourage efficiency, Medicare remains at risk for overspending.

Why GAO Did This Study

To control costs and reward efficiency, Medicare pays the majority of hospitals under PPSs, which make payments on the basis of the clinical classification of each service. In response to concerns that cancer hospitals would experience payment reductions under a PPS, beginning in 1983, Congress required the establishment of criteria under which 11 PCHs are currently exempted from the inpatient PPS and are receiving payment adjustments under the outpatient PPS. As such, PCHs are paid largely on the basis of their reported costs. GAO was asked to examine PCHs in terms of their characteristics and Medicare payments.

This report compares (1) the characteristics of PCHs with those of PPS teaching hospitals, (2) the inpatient and outpatient methodologies Medicare uses to pay PCHs and PPS teaching hospitals, and (3) Medicare payments to PCHs with payments to PPS teaching hospitals. GAO analyzed CMS claims and cost report data for 2012 to determine various characteristics, estimate inpatient payment differentials for comparable beneficiaries, and calculate the average payment differences for outpatient services.

What GAO Recommends

Congress should consider requiring Medicare to pay PCHs as it pays PPS teaching hospitals, or provide the Secretary of Health and Human Services (HHS) with the authority to otherwise modify how Medicare pays PCHs. In doing so, Congress should provide that all forgone outpatient payments be returned to the Trust Fund. HHS had no general comments.

Matter for Congressional Consideration

  1. Status: Open

    Comments: The 21st Century Cures Act enacted in December 2016 slightly reduces the additional payments to PCHs for outpatient services furnished on or after January 1, 2018, and returns savings to the Supplementary Medical Insurance Trust Fund. However, the law does not substantively change how PCHs are paid for outpatient services, which differs from how Medicare pays PPS teaching hospitals. In addition, as of March 1, 2017, no legislative action had been identified that changes how PCHs are paid for inpatient services, as GAO suggested in February 2015. Until Medicare pays these cancer hospitals in a way that encourages greater efficiency, Medicare remains at risk for overspending.

    Matter: To help the Department of Health and Human Services better control spending and encourage efficient delivery of care, Congress should consider requiring Medicare to pay PCHs as it pays PPS teaching hospitals, or provide the Secretary with the authority to otherwise modify how Medicare pays PCHs. To generate cost savings from any reduction in outpatient payments to PCHs, Congress should also provide that all forgone outpatient payment adjustment amounts be returned to the Supplementary Medical Insurance Trust Fund.
