What Medicare Part D Changes Mean for 2027
Medicare Part D is not ending in 2027, but the rules and financial support around it are changing. The drug benefit continues, while costs and plan details may shift. The temporary premium subsidy ends, not Medicare Part D.
The 2026 Medicare Part D out-of-pocket maximum and the 2027 increase
In 2026, the Medicare Part D out-of-pocket maximum is $2,100 for covered Part D drugs. In 2027, it rises to $2,400 annual cap. The cap applies to covered Part D drugs, not Part B drugs.
The maximum standard deductible rises from $615 in 2026 to $700 in 2027. A deductible is the amount you pay for eligible prescription drug costs before your plan begins sharing those costs, when the plan applies one.
Once you reach the Part D out-of-pocket cap, covered Part D drugs cost $0 for the rest of that year.
That cap first stood at $2,000 in 2025, when the coverage gap was eliminated. Medicare Part D changes 2026 included those protections, while the 2027 limit rises.
Is Medicare Part D going away in 2027?
No, Medicare Part D is not going away in 2027. The federal prescription drug coverage benefit remains in place; a temporary program supporting some premiums is what ends.
Drug price negotiation also continues to affect covered medicines. Prices for 15 additional Part D drugs negotiated by Medicare take effect January 1, 2027.
Why premiums may change when the subsidy ends
The Premium Stabilization Demonstration began in 2024 as an approximately $9.8 billion subsidy program. It was scheduled to last three years or more and ends January 1, 2027.
It applied to participating stand-alone drug plans, limiting premium increases to $35 between 2024 and 2025. CMS later allowed increases of no more than $50.
CMS Administrator Mehmet Oz said most beneficiaries could expect Part D premiums to rise by less than $10 in 2027. Treat the less-than-$10 premium forecast as an expectation for most beneficiaries, not a promise about your individual plan.
How Can Arizona Residents Check Medicare Advantage Plan Changes?
A plan can change its service area or benefits without Medicare Advantage itself disappearing. Your own notice shows what may change for the coming year, so read the Annual Notice of Change carefully.
Check the notice for changes to costs, drugs, pharmacies, and extra benefits. Part D plans can change their formularies, or lists of covered drugs, and their cost sharing from year to year.
What to look for in the Annual Notice of Change
The Annual Notice of Change lists next year’s premiums, deductibles, copayments, coinsurance, covered drugs, pharmacy networks, and extra benefits. Match each item against what you use, not what sounds nice in a brochure.
| Notice area | What to verify | Why it matters |
|---|---|---|
| Premiums and deductibles | Monthly premium and annual deductible | Changes affect yearly spending |
| Copayments and coinsurance | Costs for visits and services | Your share may rise |
| Covered drugs and formulary | Each prescription on the drug list | A medicine may move or leave |
| Pharmacy network | Your usual pharmacy’s status | Out-of-network fills may cost more |
| Extra benefits | Dental, vision, and other benefits | Added coverage can change |
How Medicare Part C differs from Part D
Medicare Part C is Medicare Advantage, a private plan that provides Medicare health coverage. Medicare Part D is prescription drug coverage, which can come through a stand-alone plan or a Medicare Advantage plan.
The Premium Stabilization Demonstration applied to stand-alone drug plans, not Medicare Advantage plans. The projected average monthly Medicare Advantage premium in 2026 is $14.00, down from $16.40 in 2025.
In 2026, the Medicare Advantage out-of-pocket maximum for approved services is $9,250, though plans may set a lower limit. That medical maximum does not include Part D cost sharing. Check the plan’s service area for your own ZIP code and county before assuming your coverage will renew unchanged.
When Can You Change Medicare Coverage?
For 2027 coverage, the main chance to change plans is October 15 through December 7, 2026. This Annual Enrollment Period lets you change several kinds of Medicare coverage.
Changes made during that period take effect January 1, 2027. You can switch between Original Medicare and Medicare Advantage, switch Medicare Advantage plans, or join, switch, or drop Part D.
Which enrollment window lets you make the change?
The Medicare Advantage Open Enrollment Period runs from January 1 through March 31. It is for people already enrolled in Medicare Advantage, and it allows one change.
During that window, you can switch to another Medicare Advantage plan or return to Original Medicare and join a Part D plan. It is not a second chance for everyone to switch any coverage.
Going 63 consecutive days or more without other creditable prescription drug coverage may mean waiting for an enrollment period to sign up. It can also lead to a late enrollment penalty.
How to change a Medicare Part D plan online
You can compare and choose a plan online through Medicare.gov. Enter your ZIP code and prescriptions, review the options, then submit your enrollment in the plan you choose.
That is how to change a Medicare Part D plan online without mailing a form. Watch for confirmation from the new plan, since an online application is not the same as a welcome letter.
Your old drug coverage ends when the new coverage begins, so you do not need to cancel the old plan separately. Keep the new plan’s confirmation letter so you can verify when the replacement coverage starts.
What Should You Check Before Choosing a Plan?
The best plan is the one that covers your own drugs and fits your expected yearly spending, not the one with the prettiest premium number. The right fit depends on your medicines, pharmacies, providers, and budget.
Compare your total yearly costs, not the premium alone. Medicare.gov Plan Finder compares Medicare Advantage and Part D plans by ZIP code using your prescriptions.
How to choose the best Medicare Part D plan for 2027
The best Medicare Part D plans for 2027 cover your medications at convenient pharmacies and fit your total-cost needs. A low monthly premium may still come with higher drug costs or a pharmacy you rarely visit.
Use these six actions to compare Medicare Part D plans:
- Read the Annual Notice of Change.
- List your medications and doctors.
- Compare plans on Medicare.gov.
- Check dental and vision benefits.
- Estimate total yearly cost.
- Enroll and save your confirmation.
Medicare Plan Finder can compare plans by ZIP code using the prescriptions you enter. Check that each drug and pharmacy fits your needs before you focus on the monthly premium.
What your yearly cost comparison should include
Projected 2026 average monthly premiums differ by plan type. Stand-alone Part D averages $34.50, Medicare Advantage with drug coverage averages $11.50, and Medicare Advantage overall averages $14.00.
| Coverage type | Projected 2026 average monthly premium | What the figure covers |
|---|---|---|
| Stand-alone Part D | $34.50 | Prescription drug plan |
| Medicare Advantage with prescription drug coverage | $11.50 | Medicare Advantage plan with drug coverage |
| Medicare Advantage overall | $14.00 | All Medicare Advantage plans |
Premiums are only one part of yearly costs. A deductible may apply once per plan year and only to certain drug tiers.
For example, a plan with a $400 deductible for Tiers 3-5 may charge $400 toward a $600 Tier 3 drug. With 20% coinsurance, the first fill costs $440, and the second costs $120.
The Medicare Prescription Payment Plan lets beneficiaries spread eligible out-of-pocket drug costs into monthly installments. Extra Help is available to older adults with incomes up to 150% of the federal poverty level.
Original Medicare has separate Part A and Part B costs, with no annual out-of-pocket maximum for those parts. The standard Part B monthly premium in 2026 is $202.90, and the annual Part B deductible is $283.
Add premiums, deductibles, copays, and coinsurance before deciding that a lower monthly premium is actually a bargain.

How to respond to fake Medicare calls
Unexpected callers may sound polished, but that alone does not prove they represent Medicare. Take a calm pause and use an official contact route instead.
Do not share Medicare or payment information with an unexpected caller, even if the caller claims there is an urgent problem.
- End the call and contact Medicare through an official channel.
- Review your Medicare Summary Notice for claims you do not recognize.
- Report suspected fraud at Medicare.gov/fraud.
- Call 1-800-MEDICARE at 1-800-633-4227 for official help.
You can review Medicare Summary Notices and report suspected fraud through Medicare.gov/fraud. Save the number for 1-800-MEDICARE so you can reach Medicare without relying on a caller’s instructions.
If a claim looks unfamiliar, check the notice and contact Medicare through an official number or website before responding to the caller.
Conclusion
A quick plan check now is less painful than discovering a surprise at the pharmacy later. Medicare Part D is not ending, but its plans can change their costs, drug lists, and networks.
Automatic renewal does not tell you whether next year’s coverage still fits. Open your current plan notice and set a reminder to compare options before the enrollment cutoff.
The 55/20/25 budget post is an optional way to think about your money, though it is not Medicare advice. Set a reminder to review your coverage, then visit the 55/20/25 budget post if you want another way to think about your money.
