Most Favored Nation (MFN) Model

Résumé

This interim final rule with comment period (IFC) implements the Most Favored Nation (MFN) Model, a new Medicare payment model under section 1115A of the Social Security Act (the Act). The MFN Model will test whether more closely aligning payment for Medicare Part B drugs and biologicals (hereafter, referred to as "drugs") with international prices and removing incentives to use higher-cost drugs can control unsustainable growth in Medicare Part B spending without adversely affecting quality of care for beneficiaries.
