Because of the prescription drug law, known as the Inflation Reduction Act, Medicare is able to negotiate directly with drug companies to improve access to some of the costliest single-source brand-name Medicare Part B and Part D drugs.

Negotiated Prices for Selected Drugs in the First Negotiation Cycle

Selected Drug List (ZIP) 

This list contains 10 drugs covered under Medicare Part D that were selected for the first cycle of negotiation based on Total Expenditures under Part D and other criteria as required by the law; the list will be updated over time. Potential updates to the list include the addition of drugs covered under Medicare Part D or Part B selected for negotiation in future years. 

File for Negotiated Prices, also known as Maximum Fair Prices in Statute (ZIP)

This file contains information on the negotiated prices under the Medicare Drug Price Negotiation Program, which the statute refers to as Maximum Fair Prices (MFPs), for 10 drugs covered under Medicare Part D that will go into effect beginning January 1, 2026, based on negotiations and agreements reached between CMS and participating drug companies. The file contains the single negotiated price for a 30-day equivalent supply of each selected drug, NDC-9 per unit price, and NDC-11 per package price. The file also contains other important information regarding updates to the NDCs and MFPs. 

The file is updated annually each year subsequent to the first initial price applicability year of the price applicability period for each selected drug, at a minimum, to show the inflation-adjusted negotiated price for the selected drug. Additional updates are made on a recurring basis to account for the application of the negotiated price to new NDC-11s of selected drugs or when an NDC-11 should no longer have the negotiated price applied. Lastly, additional updates are made to account for when a drug is no longer selected. CMS will publish the file in both .xlsx and .csv file formats.

Contract Year 2026 Medicare Advantage and Part D Proposed Rule (CMS-4208-P)

New provisions for Medicare Drug Price Negotiation Program

The Contract Year (CY) 2026 Medicare Advantage and Part D proposed rule includes a provision that would require that Part D sponsors’ network contracts with pharmacies require such pharmacies to be enrolled in the Medicare Drug Price Negotiation Program’s Medicare Transaction Facilitator Data Module. The rule also proposes to shorten the Prescription Drug Event (PDE) submission timeliness requirement for initial PDE records for selected drugs from 30 calendar days to 7 calendar days to help ensure prompt payments by drug manufacturers to dispensing entities to provide access to the MFP. To review or comment on the CY 2026 MA and Part D proposed rule during its 60-day public comment period, visit the Federal Register. Comments must be submitted no later than January 27, 2025.
