The HHS Office of Inspector General (OIG) has issued its annual report on top HHS management and performance challenges. One of the key areas identified by the OIG is incorporating program integrity into ACA implementation, given “[t]he magnitude of expenditures and impact on providers, insurers, employers, and beneficiaries from financial and health perspectives.” Areas of particular concern related to ACA implementation include, among others: programs implemented under expedited timeframes; ensuring accuracy of payments involving risk corridors, reconciliation payments, or similar payment structures; changes to Part D and other Medicare and Medicaid payments; and insurance scams and other activities that put patients at risk.
