Retirees Face Sticker Shock on Medicare Drug Plans
27 Aug
Summary
- Federal subsidy for Medicare Part D premiums ends Dec 31, 2026.
- Nearly 25 million people using stand-alone Part D face higher costs.
- Medicare Advantage plans with drug coverage are not affected.

Retirees may soon face higher Medicare drug plan premiums as a federal program that stabilized costs concludes. The Part D Premium Stabilization Demonstration, which has buffered premiums for two years, will end on December 31, 2026. This means that by 2027, nearly 25 million individuals using stand-alone Medicare Part D coverage will likely see an increase in their monthly payments.
The federal subsidy acted as a temporary measure. It absorbed some of the cost increases that stand-alone Part D plans faced following changes from the Inflation Reduction Act. Participating plans received a monthly premium reduction of $15 per member in 2025, which decreased to $10 per month in 2026. This federal support will be entirely absent in 2027.
This development places greater importance on this fall's open enrollment period for Medicare beneficiaries. Those who do not actively review their options may unintentionally renew a plan with a substantially higher premium. It is important to note that this subsidy specifically applied to stand-alone Part D plans and did not include Medicare Advantage plans that offer prescription drug coverage.
