CMS Unveils New List of Drugs Subject to Medicare Part B Inflation-Based Rebates

CMS on June 9 revealed a list of 43 Medicare Part B drugs that will be sanctioned for having their prices increase faster than the rate of inflation, as part of the Inflation Reduction Act (IRA). The number of drugs affected is almost double the number that made CMS’s initial list, which the agency made public in March. Starting in July, beneficiaries who normally pay 20% coinsurance under Part B for the 43 drugs will see their cost sharing decline based on an inflation-adjusted price. The federal government will invoice manufacturers for 2023 and 2024 Part B inflation rebates no later than fall 2025, and those funds will be deposited into the Medicare Trust Fund.

Seven of Amgen, Inc.’s medications made the list, including its blockbuster bone cancer treatment Prolia, cancer medications Kyprolis, Vectibix and Blincyto, and Nplate for immune thrombocytopenia.
