Medicare’s imminent coverage of obesity drugs opens a major new market for GLP-1 manufacturers while posing fiscal challenges for the U.S. health program
Executive summary: Medicare will start covering obesity drugs such as GLP-1 agonists for eligible beneficiaries beginning July 1, 2026, marking the first time the program includes weight-loss medications. This expands access to effective obesity treatment for millions of seniors, potentially improving health outcomes while increasing Medicare outpatient drug expenditures and creating a new revenue stream for drug manufacturers.
Who is involved: Centers for Medicare & Medicaid Services (CMS), pharmaceutical companies Eli Lilly and Novo Lilly, and approximately 65 million Medicare beneficiaries.
Likely next: CMS will conduct outreach to inform beneficiaries, monitor utilization and costs, and may adjust coverage criteria based on early utilization data.
On June 28, 2026, CNBC reported that Medicare’s upcoming coverage of obesity drugs will begin July 1, yet many seniors remain unaware due to limited government and manufacturer outreach. The decision follows years of debate over the cost-effectiveness of GLP-1 therapies and reflects a broader shift toward covering preventive treatments under Medicare. While the move could boost sales for Eli Lilly and Novo Nordisk, it also raises questions about the program’s budgetary impact and the need for safeguards against overuse.
