MILTON S. HERSHEY MEDICAL CENTER, ET AL v. ROBERT F. KENNEDY, JR
The D.C. Circuit affirmed the district court's grant of summary judgment, holding that the Secretary of Health and Human Services lacked the authority to unilaterally direct contractors to reopen final Medicare cost determinations outside the specific regulatory framework. The court ruled that the agency's attempt to apply a new reimbursement formula to settled reports was barred by explicit time limits and a prohibition on reopening based on changes in legal interpretation.
