Trump Administration Ends Medicare Part D Premium Subsidy
7/29/2026, 7:44:11 PM
Core Event
On July 28, 2026, the Centers for Medicare & Medicaid Services (CMS) announced that the Medicare Part D Premium Stabilization Demonstration will expire after the 2026 plan year. The temporary subsidy, created under the Biden administration, will not be renewed for 2027, meaning insurers will set premiums without the federal support that has kept them lower for the past two years.
Background and Policy Context
The Inflation Reduction Act of 2022 redesigned Medicare Part D, adding a $2,000 annual out-of-pocket cap and allowing limited drug-price negotiations. To smooth the transition, the Premium Stabilization Demonstration was launched in 2025 as a voluntary program that paid insurers an estimated $3.6 billion in 2026 (part of a total $9.8 billion over two years) to curb sudden premium spikes. CMS now argues that insurers have accumulated enough experience with the new benefit structure to price plans without additional federal assistance.
Data and Expected Premium Impact
- Enrollment: Roughly 25 million beneficiaries were enrolled in stand-alone Part D plans in 2026 (KFF).
- Base premium projection: CMS projects the national base beneficiary premium for 2027 at $41.33, up from $38.99 in 2026.
- Bid amount: The average monthly bid used to calculate subsidies is expected to be $296.05 in 2027.
- Premium change distribution (CMS estimate):
- About 25 % of enrollees will see premiums stay flat or decline.
- Roughly 30 % are expected to face increases of less than $10 per month.
- The remaining ?45 % could see rises of $11–$20 per month, depending on plan and location.
Official Statements and Agency Rationale
CMS Administrator Dr. The agency also noted that the Inflation Reduction Act caps annual premium increases at 6 %** through 2029.
Conflicting Projections and Gaps
Sources differ on the magnitude of expected premium hikes. CMS’s internal estimates suggest most beneficiaries will see modest increases (under $10) or even lower premiums, while the Wall Street Journal cites a broader range with “nearly half” facing $11–$20 increases. Final plan-specific premiums have not been released; CMS indicated that detailed numbers will be published in September 2026, leaving beneficiaries without precise cost information for the upcoming enrollment season.
What’s Next
CMS plans to release the final 2027 Part D premium bids and plan details in September 2026. Beneficiaries will receive their individual premium notices that fall, coinciding with the 2027 Medicare enrollment period and the lead-up to the 2026 midterm elections.
