US SB3159

Requires Medicare Part D prescription drug plans and MA-PD plans to pay long-term care pharmacies a supply fee of $30 per specified prescription in plan year 2026, with annual inflation adjustments for 2027

Supply fees apply only to drugs dispensed at the maximum fair price to eligible individuals under Medicare's drug price negotiation program, and must be paid in addition to existing pharmacy reimbursements without reducing other payments

Imposes civil money penalties of at least $10,000 per violation on plan sponsors that fail to pay the required supply fees to long-term care pharmacies

Secretary of HHS must reimburse PDP sponsors and MA organizations for the aggregate supply fees paid within 18 months after each plan year ends

Requires GAO to complete a study within 12 months on long-term care pharmacy economic sustainability, including analysis of payment trends, compliance costs, and recommendations for ensuring Medicare beneficiaries maintain access to long-term care pharmacy services
