Audit of Medicare Part D Pharmacy Fees: Geisinger Health Systems, Inc.

Medicare Part D is an optional program to help Medicare beneficiaries pay for prescription drugs. For drugs dispensed to Part D beneficiaries, Part D prescription drug plan sponsors may receive direct and indirect remuneration (DIR), which consists of rebates, subsidies, or other price concessions that decrease the costs that a sponsor incurs for a Part D drug. Part D sponsors or their pharmacy benefit managers (PBMs) may negotiate with pharmacies to charge various fees, and these fees are included as DIR. Part D sponsors are required to report their DIR to the Centers for Medicare & Medicaid Services (CMS) each year.
