Medicare Part D in 2026
Part D changed more in the last two years than in the previous fifteen. The donut hole is gone, there's now a hard cap on what you can spend out of pocket, and the phases work differently than most guides still describe. Here's the current structure — and how to pick a plan based on your actual prescriptions.

Quick Answer
How does Medicare Part D work in 2026?
Part D covers outpatient prescription drugs through private plans. In 2026 the deductible is capped at $615, you pay 25% of drug costs during initial coverage, and once your out-of-pocket spending reaches $2,100 your plan pays 100% for the rest of the year. The old coverage gap — the donut hole — was eliminated starting in 2025 and no longer exists.
The donut hole no longer exists
For years, Part D had a coverage gap where your plan largely stopped paying and you covered 25% of drug costs yourself until catastrophic coverage kicked in. That phase was eliminated starting in 2025. If a guide, a mailer, or an agent is still explaining the donut hole to you as a current feature of Part D, that information is out of date — and it matters, because the replacement is a hard annual cap that protects you far better.
2026 Part D Costs
What changed year over year. Individual plan premiums vary widely by insurer, area, and formulary.
| 2025 | 2026 | |
|---|---|---|
| Maximum deductible | $590 | $615 |
| Annual out-of-pocket cap | $2,000 | $2,100 |
| Average standalone premium | $38.31/mo | $34.50/mo |
| Coverage gap (donut hole) | Eliminated | Eliminated |
| Your share in initial coverage | 25% | 25% |
The Three Phases of Part D
1. Deductible phase
You pay full negotiated price for your drugs until you meet the plan deductible — up to $615 in 2026. Many plans set a lower deductible, or none at all, usually in exchange for a higher monthly premium.
2. Initial coverage
You pay 25% of your drug costs. Your plan covers 65% and drug manufacturers pick up the remaining 10% under the redesigned benefit. This continues until your out-of-pocket spending reaches the annual cap.
3. Catastrophic — the cap
Once your out-of-pocket drug spending hits $2,100 in 2026, you pay nothing more for covered drugs for the rest of the calendar year. This hard ceiling is the single biggest change to Part D in a generation.
The lowest premium is often the wrong plan
Every Part D plan covers a different list of drugs at different tiers. A $9/month plan that puts your medication on a high tier — or leaves it off the formulary entirely — can cost you thousands more per year than a $40/month plan that covers it well. Always compare total annual cost against your actual prescription list, not the advertised premium.
Medicare Part D FAQs
Is the Medicare Part D donut hole gone?
Yes. The coverage gap — the phase people called the donut hole, where beneficiaries paid 25% of drug costs on their own after passing an initial coverage limit — was eliminated starting in 2025 under the Inflation Reduction Act's benefit redesign. Part D now moves from the deductible phase straight through initial coverage to a hard annual out-of-pocket cap. A great deal of older content online still describes a three-phase benefit with a gap; that structure no longer exists.
How much does Medicare Part D cost in 2026?
Three numbers matter. The maximum deductible any plan can charge is $615. The average standalone Part D premium is about $34.50 per month, down from $38.31 in 2025 — though individual plans range from under $10 to over $100 depending on the insurer, your area, and the formulary. And your annual out-of-pocket spending on covered drugs is capped at $2,100. Higher-income beneficiaries also pay an IRMAA surcharge on top of their plan premium.
What is the Part D out-of-pocket cap in 2026?
$2,100, up from $2,000 in 2025. Once your out-of-pocket costs for covered prescriptions reach that amount in a calendar year, your plan pays 100% of your covered drug costs through December 31. For someone taking expensive specialty medications, this cap can be the difference between a manageable year and a financially devastating one — it is the most important number in the entire Part D benefit.
Do I need Part D if I don't take any prescriptions?
Usually yes, and the reason is the late enrollment penalty. If you go 63 or more days without Part D or other creditable drug coverage after your Initial Enrollment Period, you can be charged a permanent penalty added to your premium for as long as you have Part D. Because the penalty never goes away, enrolling in a low-cost plan while healthy is often cheaper over a lifetime than skipping coverage and paying the penalty later.
How do I choose the right Part D plan?
Match the plan's formulary to your actual medications, not the premium alone. Every plan covers a different list of drugs at different tiers, so the cheapest premium can easily be the most expensive plan for your specific prescriptions. The right approach is to price your exact drug list against every plan available in your ZIP code, then compare total annual cost — premium plus expected copays. Philip runs that comparison at no cost.
