On September 7, 2018, the United States District Court in the District of Columbia (“D.C. District Court”) vacated Medicare’s overpayment “report and return” rule as applied to Medicare Advantage Organizations (“MAOs”). The Patient Protection and Affordable Care Act (PPACA) created the requirement to report and return overpayments. The Centers of Medicare and Medicaid (CMS) issued rules to provide definitions that the PPACA did not define, create a procedure, payment options and timeframes. MAOs may no longer need to comply with CMS’ overpayment rule, but the PPACA remains intact. Providers who service Medicare beneficiaries will need to conduct the same analysis in order to comply with the PPACA “report and return” requirement.
