The average Part D premium barely moves in 2027
CMS estimates the average monthly premium for a stand-alone Part D drug plan will go from $35.09 in 2026 to $36 in 2027. CMS also says 88% of people who don't get Extra Help can choose a basic Part D plan for $10.30 a month or less.
Why some plans will rise more than the average
In recent years, CMS ran the Part D Premium Stabilization Demonstration, which helped hold down stand-alone drug plan premiums. CMS narrowed it for 2026 and is ending it in 2027. Without that help, some plans raise their premium by more than the national average, while others hold steady or drop.
An average is not your plan. Your plan's Annual Notice of Change shows your exact 2027 premium. If it went up sharply, compare it with the other plans in your county before December 7, 2026.
Fewer plans to choose from

| Item | 2026 | 2027 | Status |
|---|---|---|---|
| Plans available to the average person | 11 | 9 | final |
The average person can choose from 9 stand-alone Part D plans in 2027, down from 11 in 2026.
Fewer stand-alone drug plans means less room to shop on price. If your plan is leaving your area, you will get a notice and a chance to pick a new plan. Medicare Advantage plans with drug coverage are another option, though they come with their own network rules.
The premium is only part of what you pay
A low premium can still be the more expensive plan over a year. What you pay for your own prescriptions depends on the plan's deductible, its drug tiers and its pharmacy network.
- Deductible. For 2027, a plan may charge up to $700 before it starts sharing the cost.
- Out-of-pocket cap. Your yearly spending on covered drugs is capped at $2,400 in 2027. Premiums don't count toward it.
- Extra Help. If your income and resources are limited, Extra Help can lower your premium, deductible and copays. See help paying for Medicare.
