The Medicare Part D subsidy ending announcement arrived Tuesday, July 29, 2026, when the Centers for Medicare and Medicaid Services confirmed that a key premium stabilization program for Medicare prescription drug plans will expire at the end of 2026 and will not be renewed for 2027. The decision, announced by CMS Administrator Dr. Mehmet Oz, ends a two-year demonstration program that the Biden administration established in 2024 to keep stand-alone Medicare drug plan premiums stable during the rollout of the Inflation Reduction Act’s new Part D benefit structure. The program cost approximately $9.8 billion across 2025 and 2026, and its expiration is expected to affect the approximately 25 million seniors enrolled in stand-alone Part D prescription drug plans, with some facing premium increases and others potentially seeing stable or lower costs depending on their plan and location.
What the Medicare Part D Subsidy Actually Was
Understanding what is ending requires a brief explanation of what the program was. The Medicare Part D prescription drug benefit is not included in standard Medicare and must be purchased separately through private insurance companies. Currently the government pays billions of dollars to insurance companies as a subsidy to keep prescription drug insurance at an average of $36 per person per month, according to KFF, a health policy nonprofit.
The demonstration program was established in 2024 specifically to address a problem created by the Inflation Reduction Act. The IRA capped out-of-pocket drug spending for Part D enrollees and shifted more costs onto Part D plan sponsors, which led to higher expected costs and premiums, particularly for stand-alone prescription drug plans. To prevent a shock to beneficiaries during the transition, CMS created the premium stabilization demonstration, which provided additional federal support to insurers in two ways: reducing the base beneficiary premium used in individual plan premium calculations, and capping year-over-year premium increases. According to MedPAC, the demonstration reduced the average monthly premium by $26 in 2025 and $16 in 2026. Stand-alone Part D enrollment grew from 22.8 million in 2024 to 24.9 million in 2026 during the subsidy period.
Why the Trump Administration Is Ending the Program
The Trump administration’s rationale for ending the program is framed around two arguments. The first is that the demonstration has achieved its stabilization purpose. CMS stated that Part D plan sponsors have gained sufficient experience to support bid development, suggesting that the extra financial support provided is no longer needed as the market has adjusted to the IRA’s new cost structure. The second argument is explicitly political and anti-industry. Trump administration officials decried the Biden administration for signing the Inflation Reduction Act, which they allege bailed out major insurance companies and resulted in increased premiums for Americans. Trump officials also claim that billions of dollars were funneled to the companies through Biden’s signature legislation.
Dr. Oz articulated the administration’s position on X: “We are stabilizing the market so this bailout is no longer needed. Premiums will go up by less than $10 for most Medicare recipients, with many even seeing lower premiums.” He added that every Medicare beneficiary still has access to low-cost plans and that the administration would continue to lower prescription drug prices through most favored nation deals and the $50-per-month GLP-1 access policy for seniors.
What It Means for Your Premiums: The Competing Projections
The administration’s projection and the independent health policy analysis diverge in ways beneficiaries should understand before drawing conclusions about their own costs. The Trump administration projects that about half of enrollees will either see a premium increase of less than $10 or a premium decrease, and that most will have plans available at $10 or less per month. Oz’s X post said premiums will go up by less than $10 for most recipients.
The independent analysis from KFF is more cautious. KFF says ending the subsidies may increase premiums for some by as much as $20 a month. Juliette Cubanski, director of KFF’s program on Medicare policy, told the Washington Post: “It’s certainly possible that without this enhanced financial support in place for 2027, some Medicare beneficiaries enrolled in Part D plans could face relatively steep premium increases for drug coverage next year.”
The critical limitation of both projections is that neither is definitive yet. CMS will not publish final 2027 premiums and individual plan details until September 2026, meaning beneficiaries do not yet know precisely how much their own coverage will cost. The insurance companies offering Part D plans, which include UnitedHealth Group, Humana, and Aetna, are currently in the process of submitting their 2027 bids to CMS based on the new subsidy-free framework.
Who Will Be Most Affected
The subsidy’s expiration will not affect all Medicare Part D enrollees equally. The subsidies have been most helpful for stand-alone Medicare drug plans rather than Medicare Advantage plans, which have more flexibility to keep premiums low. As a result, removing the subsidies will affect people with traditional Medicare plans the most.
Stacie Dusetzina, a professor of health policy at the Vanderbilt University School of Medicine, acknowledged that the subsidies were never meant to be permanent but expressed concern about the timing: while the subsidies were never meant to be permanent, ending them now is concerning. Her concern reflects the fact that the IRA’s Part D changes are still relatively new, and the market’s adjustment to the new cost structure is not yet complete in all segments.
Advocacy group Protect Our Care said even small rises in premiums could be too much for some seniors, pointing to the population of fixed-income Medicare beneficiaries for whom a $10 to $20 monthly increase represents a meaningful percentage of their available income for healthcare spending.
The Broader Healthcare Cost Context
The Medicare Part D subsidy decision arrives at a moment when healthcare costs are consistently among the top concerns for American voters. The move comes as Affordable Care Act subsidies have also expired, compounding the cost pressure on Americans purchasing health insurance through the marketplace. The ACA subsidy expiration affected people purchasing coverage through the health insurance exchange, while the Medicare Part D change affects seniors already enrolled in the government’s prescription drug program.
Together, the two subsidy expirations represent a significant withdrawal of federal support for private health insurance markets, with the administration framing both as corrections to programs that benefited insurance companies rather than patients. Critics of both decisions argue that the practical effect falls on beneficiaries, not insurers, who will adjust their pricing to reflect the new subsidy environment regardless of the administration’s framing.
What to Do Before Open Enrollment
The Medicare annual enrollment period runs from October 15 through December 7, 2026, with 2027 plan details becoming available in September. Beneficiaries enrolled in stand-alone Part D plans should take three specific steps before open enrollment begins. First, do nothing until September, when CMS publishes actual 2027 plan premiums and benefit details. Any decision made before that date will be based on projections rather than confirmed numbers. Second, use the Medicare Plan Finder at medicare.gov during open enrollment to compare actual 2027 plan costs against your current coverage, including premiums, deductibles, and the cost of your specific medications under each available plan. Third, contact your State Health Insurance Assistance Program, known as SHIP, for free one-on-one counseling. SHIP counselors can review your specific medications and circumstances and help you identify the plan that minimizes your total drug costs, not just the premium.
Latest Updates
The Trump administration’s decision to end the Medicare Part D premium stabilization demonstration was first reported by the Wall Street Journal and officially confirmed by CMS on July 29, 2026. ABC News confirmed the full details of the announcement, Dr. Oz’s X post, the administration’s projection that most enrollees will see increases of less than $10 or premium decreases, and the competing KFF projection that some could face increases of up to $20 per month. The Washington Post confirmed KFF’s Juliette Cubanski’s more cautious assessment and the September timeline for final premium details. The New York Times confirmed the context of the IRA’s Part D changes as the backdrop for the demonstration program and the approximately 25 million stand-alone Part D enrollees who will be most directly affected.

Broader Implications
The Medicare Part D subsidy decision is a meaningful test of the Trump administration’s claim that eliminating insurance industry support mechanisms will benefit patients rather than harm them. The administration’s argument that the subsidies primarily benefited insurers rather than beneficiaries will be evaluated against real-world premium data when September’s plan details are released. If the September numbers confirm the administration’s projection that most enrollees see increases of less than $10 or premium decreases, the decision will be difficult to criticize on practical grounds. If the numbers confirm KFF’s more cautious projection that some enrollees face increases of $20 or more, the political pressure on the administration will intensify heading into the midterm elections the ABC News report explicitly referenced as the backdrop for this healthcare cost environment.

3. FREQUENTLY ASKED QUESTIONS
- What is the Medicare Part D subsidy that is ending in 2027?
The Medicare Part D premium stabilization demonstration was a two-year program established by the Biden administration in 2024 to keep stand-alone prescription drug plan premiums stable during the rollout of the Inflation Reduction Act’s new Part D benefit structure. The program cost approximately $9.8 billion across 2025 and 2026 and reduced average monthly premiums by $26 in 2025 and $16 in 2026, according to MedPAC.
- Will my Medicare Part D premiums go up in 2027?
It depends on your specific plan and location. The Trump administration projects that about half of enrollees will see a premium increase of less than $10 or a premium decrease. KFF projects some enrollees could see increases of up to $20 per month. Final 2027 plan premiums will not be published by CMS until September 2026, so no one can confirm their specific cost change until then.
- Who will be most affected by the Medicare Part D subsidy ending?
The subsidy ending will have the greatest impact on seniors enrolled in stand-alone Medicare drug plans, which are purchased separately alongside traditional Medicare. Medicare Advantage plan enrollees will be less directly affected because those plans have more flexibility to manage premium costs. People on fixed incomes who rely on traditional Medicare for their primary coverage are the most financially vulnerable to any premium increase.
- Why is the Trump administration ending the Medicare Part D subsidy?
The administration said the premium stabilization demonstration has achieved its purpose and that plan sponsors now have sufficient experience to set bids without additional support. CMS Administrator Dr. Mehmet Oz also characterized the subsidy as a bailout for insurance companies rather than a benefit to patients, and said eliminating it is consistent with the administration’s broader approach of removing what it views as unnecessary industry support mechanisms.
- When will I know what my Medicare Part D premiums will be in 2027?
CMS will publish final 2027 Medicare plan premiums and benefit details in September 2026, before the Medicare annual enrollment period runs from October 15 through December 7, 2026. Beneficiaries should use the Medicare Plan Finder at medicare.gov during open enrollment to compare their options, or contact their State Health Insurance Assistance Program for free counseling.
