Medicare Part D Premium Stabilization Subsidy Ends Early, Raising Premium Uncertainty for Millions

Core Event
The federal government is ending the Medicare Part D Premium Stabilization Demonstration—a roughly $9.8 billion subsidy that helped keep standalone prescription-drug plan premiums low. The program, launched in 2024 after the Inflation Reduction Act capped deductibles, will cease at the beginning of 2027, a year earlier than originally planned.
Background & Context
The subsidy was created to offset cost increases insurers expected once the 2025 deductible caps took effect. It limited premium hikes to $35 in 2024-2025 and later to $50, while providing direct payments to insurers. In 2025, beneficiaries’ premiums were on average $26 lower than they would have been without the subsidy; in 2026 the average reduction was about $16, according to a federal report.
Impact on Beneficiaries
Without the subsidy, many enrollees could see higher monthly premiums and altered cost-sharing. The Low-Income Subsidy (Extra Help) remains unchanged, but those not qualifying may face larger out-of-pocket costs. Protected drug classes—such as antidepressants, immunosuppressants, and cancer treatments—must continue to be covered, with specialty-tier co-insurance ranging from 25 % to 33 %. The Medicare GLP-1 Bridge program, an 18-month pilot offering $50 copays for certain weight-loss drugs, is unaffected but will end at the close of 2027.
Official Statements & Responses

- Ryan Ramsey, associate director of health coverage and benefits at the National Council on Aging, emphasized that Medicare Part D itself is not ending and urged those considering Medicare Advantage to verify eligibility for supplemental Medigap coverage.
