The Trump administration is ending the Medicare Part D Premium Stabilization Demonstration, a Centers for Medicare & Medicaid Services (CMS) program that provided payments to insurers to help keep prescription drug plan premiums stable. Quartz reports that the initiative, which has delivered billions to participating insurers to limit premium increases, is being discontinued and will end after this year. Newsweek reports that CMS announced the demonstration’s expiration and specifies that it will end after 2026. CMS’s announcement indicates that the program will not continue beyond its current timeframe, meaning insurers and Medicare beneficiaries may see changes in how Part D premiums are set once the subsidy stops. Across both reports, the core point is that a federal subsidy supporting stable Medicare Part D premiums is scheduled to end, following CMS direction, with the program’s termination occurring at the end of the current period.
