CMS Most Favored Nation

Most Favored Nation Model for Medicare Part B Drugs and Biologicals Interim Final Rule with Comment Period

The Centers for Medicare & Medicaid Services (CMS) is announcing a new payment model, the Most Favored Nation (MFN) Model (or the “MFN Model”), and issuing a corresponding Interim Final Rule with Comment Period (IFC). The MFN Model will lower prescription drug costs by paying no more for high-cost Medicare Part B drugs and biologicals (hereinafter called “drugs”) than the lowest price that drug manufacturers receive in other similar countries. The MFN Model will also pay providers a flat add-on amount for each dose of an MFN drug, instead of a percentage of each drug’s cost, removing the tie between drug cost and the add-on amount. Beneficiaries will pay lower coinsurance for these high-cost Part B drugs and will not pay coinsurance on the add-on payment. The MFN Model will require participation of Medicare providers and suppliers that receive separate Medicare Part B fee-for-service payment for the model’s included drugs, with certain exceptions, and begin nationally January 1, 2021.
