The Trump administration plans to end the Medicare Part D Premium Stabilization Demonstration after 2026, eliminating roughly $3.6 billion in annual subsidies that have helped insurers keep prescription drug plan premiums stable for seniors. The move, announced July 28, 2026, means that roughly 25 million people with Part D coverage will likely face higher rates starting in 2027.
The subsidy program, announced by the Centers for Medicare and Medicaid Services in July 2024, provides participating insurers with direct payments to offset premium increases. In 2025, the program offered up to a $15 monthly subsidy per plan; that was reduced to $10 for 2026. The demonstration also caps year-over-year premium increases at $35 per month for participating standalone drug plans.
A Trump administration official argued that the subsidies had the unintended effect of encouraging insurers to raise rates, knowing the government would absorb the extra cost. The official stated the subsidies were not necessary and that other policies remain in place to help control Part D costs.
The Premium Stabilization Demonstration was created to address sharp premium increases that occurred after the Inflation Reduction Act redesigned the Part D benefit in 2024 and 2025. The program was voluntary, allowing insurers to participate if they agreed to limit premium growth in exchange for federal support. Without the subsidy, experts anticipate that standalone Part D premiums could rise substantially in 2027, potentially prompting more seniors to switch to Medicare Advantage plans, which often bundle drug coverage with medical benefits.
The timing of the announcement is significant for the 2026 midterm elections, as healthcare affordability remains a top concern for older voters. Seniors typically learn about their 2027 Part D rates in the fall, which could influence the political landscape heading into the election cycle.
