Some retirees may get an unwelcome surprise when they compare their 2027 Medicare drug-plan premium with what they are paying today. A federal program that has silently cushioned stand-alone Medicare Part D premiums for two years ends December 31. On July 28, 2026, the Centers for Medicare & Medicaid Services (CMS) announced that the Part D Premium Stabilization Demonstration will not continue into 2027.
That puts extra weight on this fall's open enrollment. Someone who lets a stand-alone drug plan renew without checking the 2027 premium could be carrying forward a plan whose economics just changed. The effect will not be identical everywhere, and final plan premiums will not be public until September. But for the nearly 25 million people using stand-alone Part D coverage, the federal cushion underneath 2025 and 2026 premiums is going away.
What the Subsidy Was Actually Doing
The subsidy was essentially a temporary shock absorber. When the Inflation Reduction Act changed who pays what for expensive prescriptions, standalone Part D plans were asked to shoulder a bigger share of the cost. Rather than let all of that pressure spill immediately into premiums, the federal government stepped in to soften the landing.

In 2025, participating plans received a $15-per-member monthly premium reduction, along with a limit on how sharply premiums could rise from the year before. The cushion shrank to $10 a month in 2026. In 2027, it disappears altogether. That does not mean every drug-plan premium is about to jump by the same amount. It does mean standalone Part D plans will be setting 2027 prices without a federal assist they had for the past two years. Medicare Advantage plans with drug coverage were never part of this particular program, so the ending of the subsidy is specifically a standalone Part D issue.
One Premium Protection Is Still in Place
The end of the subsidy does not mean Part D premiums can suddenly run wild. Another guardrail is still in place: through 2029, the national base beneficiary premium cannot rise by more than 6% a year. For 2027, that benchmark moves from $38.99 to $41.33.
That does not mean everyone will pay $41.33. Think of it as a reference point CMS uses when plan premiums are calculated. What lands on an enrollee's bill can be higher or lower depending on the plan. And one of the biggest protections remains untouched. In 2027, out-of-pocket spending on covered Part D drugs is still capped at $2,400 for the year. So retirees are losing one layer of help, not every layer. The temporary premium cushion is going away, while the ceiling on covered drug spending stays put.
IRMAA Still Sits on Top
Higher-income beneficiaries have another layer to consider. The income-related monthly adjustment amount (IRMAA) for Part D is added to the plan's own premium and generally looks back two years at modified adjusted gross income (MAGI). That means 2025 income will generally determine whether someone pays Part D IRMAA in 2027.
For Medicare, MAGI is adjusted gross income plus tax-exempt interest, so even income that feels "tax-free" can still matter. The final 2027 thresholds and surcharge amounts are not yet available, so the 2026 table should not be treated as next year's bill. A qualifying life-changing event that later offsets income can support an SSA-44 request. A voluntary Roth conversion or investment sale generally cannot. (IRMAA is one of several premium traps we mapped in a free Medicare guide.)
September Will Supply the Number That Matters
You do not need to make a decision yet. The full 2027 plan prices will arrive in September, which gives retirees time to see what actually changed before open enrollment begins. Once they do:
-
Put your current prescriptions into Medicare Plan Finder and compare what you would spend for the full year, not just the monthly premium. Drug coverage and pharmacy costs can shift too.
-
See how your current plan stacks up against the 2027 alternatives before letting it renew automatically.
-
If your income is high enough for IRMAA, check the new 2027 thresholds when they are released so you know how much of the bill comes from the plan and how much comes from the surcharge.
The federal cushion disappears December 31, but that does not mean every premium is headed sharply higher or that everyone needs a new plan. It simply makes this a good year to open the renewal notice instead of letting it make the decision for you.
