2027 Part D amounts
| Part D amount | 2027 | 2026 |
|---|---|---|
| Yearly out-of-pocket cap | $2,400 | $2,100 |
| Highest deductible a plan can charge | $700 | $615 |
| Covered insulin, per month's supply | No more than $35 | No more than $35 |
CMS set these amounts in its 2027 Rate Announcement. Your plan's deductible can be lower than the maximum, or zero.
How the cap works through the year
- Deductible. If your plan has one, you pay the full cost of covered drugs until you meet it. Covered insulin and recommended vaccines aren't subject to the deductible.
- Your share. After the deductible, you pay your plan's copays or coinsurance.
- The cap. When your out-of-pocket spending reaches $2,400, you automatically pay $0 for covered Part D drugs for the rest of the calendar year.
- Next January. The count starts over on January 1, 2028.
Spreading costs over the year
The Medicare Prescription Payment Plan lets you pay your drug costs in monthly amounts across the year instead of all at once at the pharmacy. It doesn't lower your total costs, and it's most helpful if you have high costs early in the year. Ask your drug plan to sign you up. You still pay your plan premium separately.
Drug coverage in Oklahoma for 2027
- Plan choices: CMS data show 9 standalone Part D plans in Oklahoma for 2027, plus Medicare Advantage plans with drug coverage that vary by county. See Part D in Oklahoma.
- Extra Help: lowers your Part D costs if your income and resources are limited. In 2027, the most you pay for a covered drug with Extra Help is $5.80 for a generic and $14.40 for a brand-name drug. OKDHS says that when it tells Social Security you qualify for a Medicare Savings Program, Social Security signs you up for Extra Help. See Medicare Savings Programs in Oklahoma.
- Check your drugs every fall. Plans change their drug lists and pharmacies each year. Use the drug cap calculator to estimate your year.

Frequently asked questions
Do my monthly premiums count toward the cap?
No. The cap counts your deductible, copays and coinsurance for covered drugs, plus certain payments made for you, such as through Extra Help. You keep paying your plan's monthly premium, if it has one, even after you reach the cap.
Is there still a donut hole?
No. The Part D coverage gap ended in 2025. In 2027 you pay up to the deductible, then your plan's cost sharing until you reach the cap, and then nothing for covered drugs.
Does a drug discount card count toward the cap?
No. Medicare.gov says that when you use a discount card instead of your Medicare drug plan, what you pay doesn't count toward your deductible or out-of-pocket maximum.
