In a unanimous decision, the Justices found that the Department of Health and Human Services (HHS) exceeded its legal authority when it cut Medicare reimbursement rates for outpatient drugs by 28.5 percent at 340B-eligible hospitals in 2018. The justices wrote that the Centers for Medicare and Medicaid Services (CMS) shouldn’t have cut payments to these hospitals without first surveying their average drug acquisition costs, as required by statute.
CMS must now figure out how to repay 340B hospitals the difference in reimbursement for 2018 and 2019, the two years the unlawful cuts were in effect, during which time it redistributed those savings to all hospitals in the form of higher reimbursement for outpatient services. (For an explainer on the mechanics of the 340B program, see our overview here, and for more details on this Supreme Court case, see our summary here.)
The Gist: This decision was a narrow ruling on administrative grounds, and did not touch on the larger policy debates concerning the 340B program. While 340B-eligible health systems can breathe a momentary sigh of relief, they are still facing significant, ongoing revenue disruptions as at least 17 pharmaceutical manufacturers are restricting discounted drug sales to contract pharmacies.
Scrutiny of the 340B program, which has grown to include over 40 percent of US hospitals, will continue to raise questions about whether there are better ways to subsidize the operations of hospitals serving low-income patients, and to ensure that underserved patients have access to lifesaving treatments.
