The Trump administration will end a temporary Medicare Part D subsidy that has reduced prescription-plan premiums for two years. Federal officials say most increases should be under $10 a month, but final costs vary by plan and will not be known until fall enrollment information is released. The subsidy was created in 2024 to soften premium changes associated with the Inflation Reduction Act’s redesign of Medicare prescription coverage.
The program cost the federal government an estimated $3.6 billion in 2026. CMS Administrator Mehmet Oz said most beneficiaries would see increases below $10 a month and some could pay less. About 25 million Americans hold Medicare Part D plans, though plan availability and premiums differ by location.
Part D beneficiaries paid an average monthly premium of $36 in 2026, and the subsidy offset an average of $16 according to MedPAC. The change does not remove the annual out-of-pocket cap, which is projected to rise from $2,100 in 2026 to $2,400 in 2027. The federal government separately negotiates prices for selected high-cost Medicare drugs under authority enacted in 2022.
CMS is scheduled to release 2027 premium information in September before the annual plan-selection period. Older adults can compare and change plans annually, so a premium increase in one plan does not establish the lowest available cost in a market.
The evidentiary boundary at publication is specific: Final plan premiums are not available, CMS has not established how many beneficiaries will pay more, and estimates do not include each person’s drug list or plan choices. The current account therefore distinguishes completed events from announced, proposed or still-contested steps. Statements by governments, companies, litigants and advocacy organizations establish what those parties said; they are not treated as independent proof of every underlying assertion. Numerical values describe the source period and category identified in the reporting and may be revised by the responsible institution.
The next public records expected to update this account are CMS’s September premium and plan files and insurer bids and beneficiary choices during open enrollment. Until those records appear, the dates, totals, procedural posture and attributed descriptions above are the latest checked account for the July 31 edition. A later filing, official release, verified field report or corrected dataset could change a total or timetable without erasing the documented sequence at this cutoff.
