Title 42 › CHAPTER 7 — SOCIAL SECURITY › SUBCHAPTER XI — GENERAL PROVISIONS, PEER REVIEW, AND ADMINISTRATIVE SIMPLIFICATION › Part E — Price Negotiation Program To Lower Prices for Certain High-Priced Single Source Drugs › § 1320f–3
The Secretary must negotiate with a drug’s maker to set a maximum fair price while the agreement is in effect. The Secretary must use a single method that aims for the lowest fair price. The drug maker must send required information by March 1 of the year the drug is published. The Secretary must give a written first offer by June 1 after publication and must explain why that price was chosen. The maker has 30 days to accept or send a written counteroffer with its justification. The Secretary must reply in writing, and all talks must finish before November 1 after publication. The Secretary cannot agree to a price higher than the ceiling or lower than any required floor. The ceiling is the lower of two amounts. One is the Medicare Part D plan enrollment‑weighted negotiated price (net of all price concessions) summed across plans, or for Part B drugs the prior year Medicare Part B payment amount. The other is a percent of the drug’s average non‑Federal average manufacturer price (ANFMAP) from 2021 (or the first full year after market entry) adjusted by the Consumer Price Index from September 2021 (or December of that first full year) to the September before publication. For initial price year 2026 that adjusted 2021 price is used; for 2027 and later it is the lower of the adjusted 2021 price or the ANFMAP for the year before publication. The percent used is 75% for short‑monopoly drugs, 65% for extended‑monopoly drugs, and 40% for long‑monopoly drugs. An extended‑monopoly drug is one approved/licensed 12 to fewer than 16 years ago; a long‑monopoly drug is one approved/licensed at least 16 years ago. Vaccines licensed under the vaccine law are excluded from those two groups. A temporary floor of 66% of the adjusted 2021 ANFMAP applies for certain qualifying single‑source small biotech drugs whose first initial price year is 2029 or 2030. Starting in 2028, the Secretary must renegotiate prices for drugs that gain a new approved use, move into extended or long monopoly status, or have material changes in the facts used to set price. All extended‑ and long‑monopoly eligible drugs must be selected for renegotiation; other eligible drugs are chosen if renegotiation is likely to change the price substantially. The renegotiation process should follow the same steps, limits, and formulas as the original negotiations. A new maximum fair price must take effect no later than the first day of the first calendar quarter that starts after the applicable date set in the negotiation process.
