Health: pharmaceuticals; reporting certain information and regulating certain conduct related to drugs and the federal 340B program; provide for. Creates new act.

HB 4878 regulates Michigan's participation in the federal 340B drug pricing program, which allows qualifying hospitals to purchase drugs at discounted prices. The bill requires drug manufacturers to report annual price increases exceeding 15% for drugs costing over $40 per treatment course (Sec. 7), and mandates hospitals using 340B discounts to spend savings on patient services or community health programs (Sec. 11). Hospitals must also report detailed financial data about 340B drug transactions to the state by November 2026 (Sec. 15). These provisions directly affect drug manufacturers, hospitals, and pharmacies participating in the 340B program, aiming to increase transparency and ensure discounts benefit patient care.
