Prescription Drug Affordability Board - Authority and Stakeholder Council Membership (Lowering Prescription Drug Costs for All Marylanders Now Act)

HB 424 creates a Prescription Drug Affordability Board with authority to set upper payment limits for prescription drugs causing affordability challenges in Maryland. The Board must consider costs like administration and delivery when setting limits, and it must reconsider limits if a drug becomes a "current shortage" (listed on the FDA shortage database or determined by the Board). This directly affects drug manufacturers (who set wholesale costs), pharmacies (receiving reimbursements), and healthcare providers, particularly those in the 340B program. The bill prohibits setting new limits for drugs in shortage and bans enforcement of limits against Medicare Part C/D plan reimbursements.
