Medicare Part D in 2027: 7 Changes to Know Before October 15
Medicare Part D is changing again for 2027. Some changes may help protect beneficiaries from high prescription costs. Others may affect premiums, deductibles, or the way your current plan covers your medications.
The 2027 Medicare Annual Enrollment Period runs from October 15 through December 7, 2026. During this time, you can review and change your Medicare Advantage or Medicare Part D coverage for the coming year. Changes made during this period generally take effect on January 1, 2027.
You do not have to wait until October 15 to prepare. Gathering your medication list and reviewing your current coverage before enrollment begins can make the process clearer and less stressful.
Seven Changes and Considerations to Know
1. The Temporary Part D Premium Stabilization Subsidy Is Ending
The temporary Part D Premium Stabilization Demonstration is scheduled to end after 2026.
This demonstration helped reduce premium volatility for participating stand-alone prescription drug plans during the early years of the redesigned Medicare Part D benefit.
CMS reduced the level of support in 2026 and has announced that the demonstration will not continue for 2027.
The end of this temporary subsidy does not mean every Part D plan will have the same premium increase.
Plan premiums will continue to vary by insurer, plan, service area, and benefit design.
CMS reported that the 2027 national base beneficiary premium is $41.33. This is a national calculation used in determining plan premiums. It is not necessarily the amount each individual will pay.
The Inflation Reduction Act’s separate premium stabilization rule remains in place through 2029. That provision limits annual increases in the national base beneficiary premium to no more than 6% per year.
What this means for you: Do not assume that your current plan will remain the lowest-cost option. Review the actual 2027 premium and estimated annual prescription costs before deciding whether to stay enrolled.
2. The Standard Part D Deductible Rises to $700
For 2027, the standard Medicare Part D deductible increases from $615 to $700.
A deductible is the amount you may pay for covered prescriptions before your plan begins sharing costs, although some plans may charge different amounts or cover certain medications before the deductible applies.
The deductible is only one part of your prescription costs. A plan with a lower deductible may still cost more overall if it has higher premiums, less favorable copayments, or limited coverage for your specific medications.
That is why comparing deductibles alone can be misleading.
3. The Annual Part D Out-of-Pocket Cap Rises to $2,400
The Medicare Part D annual out-of-pocket threshold increases from $2,100 in 2026 to $2,400 in 2027.
This cap applies to covered Part D prescription drugs. Once you reach the annual limit, you generally do not pay additional cost-sharing for covered Part D drugs for the rest of the calendar year.
The cap can provide important protection for people who take high-cost medications. However, it does not mean every prescription will be inexpensive. Your medications must be covered by the plan, and the plan’s formulary, pharmacy network, and coverage rules still matter.
The out-of-pocket cap also does not automatically include every healthcare expense. Medical services, premiums, non-covered medications, and other costs may be handled separately.
What this means for you: If you take specialty medications or several ongoing prescriptions, compare your estimated annual drug costs: not just the monthly premium.
4. Your Monthly Premium May Change When the Subsidy Ends
The end of the temporary stabilization demonstration may cause some stand-alone Part D premiums to rise in 2027.
CMS has indicated that many beneficiaries may see increases of approximately $10 per month or less, but actual plan-specific changes can be higher, lower, or nonexistent.
Your premium may also be affected by factors such as:
- The plan’s bid for 2027
- Your county or service area
- The plan’s benefit design
- Whether you receive financial assistance
- Whether you have income-related Medicare adjustments
- Changes in the plan’s pharmacy network or formulary
The national base premium is useful for understanding Medicare’s overall calculations, but it does not replace a personalized plan review.
A plan with a slightly higher premium could still be less expensive overall if it covers your medications at lower costs.
The reverse can also be true.
5. Negotiated Prices Begin for 19 Brand-Name Products
Negotiated Medicare drug prices take effect on January 1, 2027 for a second group of selected Part D drugs.
CMS identifies 15 selected drug groupings, representing 19 brand-name products. The products include:
- Ozempic, Rybelsus, and Wegovy
- Trelegy Ellipta
- Xtandi
- Pomalyst
- Ibrance
- Ofev
- Linzess
- Calquence
- Austedo and Austedo XR
- Breo Ellipta
- Tradjenta
- Xifaxan
- Vraylar
- Janumet and Janumet XR
- Otezla
These negotiated maximum fair prices may lower costs for some beneficiaries who take the selected medications. However, the effect on your personal costs depends on your plan, dosage, pharmacy, coverage stage, and other benefit rules.
A negotiated price does not guarantee that a particular plan will be the best option for you. You still need to check whether your medication is covered, what tier it occupies, and whether your preferred pharmacy participates in the plan’s network.
For the official list and details, review the CMS Medicare Drug Price Negotiation Program information.
6. Formularies, Tiers, and Pharmacy Networks Can Change
Every year, Part D plans can change their formularies and cost-sharing rules. A formulary is the plan’s list of covered prescription drugs.
For 2027, review whether:
- Each of your medications remains covered
- A medication has moved to a different cost tier
- Your plan requires prior authorization
- Step therapy applies
- Quantity limits have changed
- Your preferred pharmacy remains in-network
- Mail-order pricing is available
- Your medication is covered under Part D or another part of Medicare
These details can affect your costs more than the premium alone.
A medication review should use your complete list, including the drug name, dosage, frequency, and the pharmacy you normally use. Even a small change in dosage or pharmacy can affect the comparison.
7. Annual Enrollment Is the Right Time to Recheck Your Entire Prescription Strategy
The Annual Enrollment Period is not only for people who are unhappy with their plans. It is also an opportunity to confirm that your existing coverage still fits your current needs.
Your situation may have changed since last year.
You may have:
- Started or stopped a prescription
- Changed doctors
- Added a new diagnosis
- Moved to a different pharmacy
- Experienced higher medication costs
- Begun using mail-order services
- Lost access to a preferred pharmacy
- Changed your household income
- Reached a new stage of treatment
Even if your plan worked well last year, it may not be the most suitable choice for 2027.
