Trump administration ends temporary Medicare Part D insurer subsidy amid cost concerns

The Trump administration has moved to end a provisional, non-statutory subsidy that has been paying insurers under Medicare Part D, with the phase-out scheduled for 2027. Launched by the Biden administration as a “premium stabilization demonstration,” the aid was designed to prevent large premium hikes ahead of the 2024 election but effectively transferred the bulk of costs to taxpayers. The California Democratic Party accused the move of jeopardizing the health of roughly 25 million seniors, though the underlying Part D program, established in 2003, remains untouched.

Estimates indicate the bailout added about $40 billion in federal outlays for 2025 and 2026, inflating the program’s long-term cost projections. CMS projects that most enrollees will experience either unchanged or lower premiums, while about 30 percent may see increases under $10 per month. By ending the extralegal aid, the administration aims to reduce federal spending while preserving the competitive structure of Part D, which has already seen inflation-adjusted premium declines over the past 15 years.
