Since that time, there have been multiple healthcare reform measures, including the Inflation Reduction Act of 2022 (“IRA”) which, among other things, allows HHS to directly negotiate the selling price of a statutorily specified number of drugs and biologics each year that CMS reimburses under Medicare Part B and Part D. The negotiated price may not exceed a statutory ceiling price. Only high-expenditure single-source biologics that have been approved for at least 11 years (7 years for small molecule drugs) can be selected by CMS for negotiation, with the negotiated price taking effect two years after the selection year.
