Supreme Court of the United States

(1) Whether a group health plan that provides uniform reimbursement of all dialysis treatments observe the prohibition provided by the Medicare Secondary Payer Act that group health plans may not “take into account” the fact that a plan participant with end stage renal disease is eligible for Medicare benefits; (2) whether a plan that provides the same dialysis benefits to all plan participants, and reimburses dialysis providers uniformly regardless of whether the patient has end stage renal disease, observe the prohibition under the Medicare Secondary Payer Act that a group health plan also may not “differentiate” between individuals with end stage renal disease and others “in the benefits it provides”; and (3) whether the Medicare Secondary Payer Act is a coordination-of-benefits measure designed to protect Medicare, not an antidiscrimination law designed to protect certain providers from alleged disparate impact of uniform treatment.
