Simulating the Impact of the Drug Price Negotiation Proposal in the Build Back Better Act

The Build Back Better Act (BBBA) includes a range of health and other proposals supported by President Biden, including a proposal to allow the federal government to negotiate the price of some prescription drugs covered under Medicare Part B (administered by physicians) and Medicare Part D (retail outpatient drugs). This brief illustrates the potential scope of the drug price negotiation proposal in the BBBA. This analysis is designed to highlight the types of Medicare-covered drugs that could be subject to negotiation, and which of the current top-spending drugs covered by Part B and Part D could be subject to price negotiation, and in what years, if the BBBA is enacted.
