Quick Answer: Medicare Part D is prescription drug coverage from a private, Medicare-approved plan, either standalone or bundled into a Medicare Advantage plan. It helps pay for your medications and caps how much you’ll spend out of pocket on covered drugs each year ($2,100 in 2026).
| Plan type | Standalone (PDP) or bundled into Medicare Advantage (MAPD) |
| Who it's for | Anyone with Medicare, even without current prescriptions (avoids a late penalty) |
| 2026 max deductible | $615 |
| 2026 out-of-pocket cap | $2,100 — 100% covered after that |
| Coverage gap ("donut hole") | Eliminated |
| Enrollment windows | Initial Enrollment Period, Oct 15–Dec 7 (AEP), Jan 1–Mar 31 (if in a Medicare Advantage plan) |
| Late enrollment penalty | Yes, if you go 63+ days without creditable drug coverage |
Medicare drug coverage (Part D) helps pay for the prescription drugs you take. It’s optional, but even if you don’t take medications now, it’s worth understanding your options: if you decide not to get drug coverage when you’re first eligible and don’t have other creditable coverage (like coverage from an employer or union) or qualify for Extra Help, you’ll likely pay a late enrollment penalty if you join a plan later — generally for as long as you have Medicare drug coverage.
To get Medicare drug coverage, you must join a Medicare-approved plan. Costs and covered drugs (the plan’s “formulary”) vary significantly between plans, so it’s worth comparing rather than picking the first one you see.

In either case, you must live in the plan’s service area and be lawfully present in the U.S.
What Does Part D Cost In 2026?
Costs vary by plan and depend on your income, but as of 2026 the Part D standard benefit works in three phases: a deductible phase (plans can charge up to $615 before coverage kicks in), an initial coverage phase where you pay a percentage of drug costs, and a catastrophic phase once your out-of-pocket spending on covered drugs reaches $2,100 for the year — after that, your plan covers 100% of costs for the rest of the year. There’s no more “coverage gap” or “donut hole.” If you’d rather not pay large amounts at the pharmacy counter, the Medicare Prescription Payment Plan lets you spread your out-of-pocket drug costs into monthly installments across the year instead.
When Can I Join, Switch, Or Drop A Plan?
Already Have Coverage? It’s Worth Checking Every Year.
Plan formularies, pharmacy networks, and premiums can change from year to year, even if your plan’s name stays the same. We recommend reviewing your Part D or Medicare Advantage drug coverage every Annual Enrollment Period to make sure your medications are still covered at a price that makes sense, especially if you’re also weighing a Medicare Supplement plan or hospital indemnity coverage.

Talk to us when you’re first eligible for Medicare, every Annual Enrollment Period, or any time your doctor changes or adds a new prescription.
Do I need Part D if I don’t take any medications? It’s worth having minimal coverage to avoid a late enrollment penalty, since needs can change quickly.
Can I get help paying for Part D if I have a limited income? Yes, the Extra Help program can lower premiums, deductibles, and copays for those who qualify.
What happens if my drug isn’t on my plan’s formulary? You may be able to request a formulary exception, switch plans during an eligible enrollment period, or ask about a therapeutic alternative.

If you go 63 days or more without creditable prescription drug coverage after you’re first eligible, you’ll likely pay a late enrollment penalty added to your premium for as long as you have Medicare drug coverage.
The penalty is based on how many months you went without creditable drug coverage. It’s calculated as a percentage of the national base beneficiary premium and is added to your monthly Part D premium.
No. As of 2025, the donut hole was eliminated. Part D now works in three phases — deductible, initial coverage, and catastrophic — with an annual out-of-pocket cap ($2,100 in 2026) after which your plan covers 100% of costs for the rest of the year.
Yes. During the Annual Enrollment Period (October 15 – December 7), you can switch, join, or drop a Part D or Medicare Advantage drug plan for coverage starting the following January 1.
Not necessarily. Plan formularies and pharmacy networks can change annually even if the plan name stays the same, which is why we recommend reviewing your coverage every Annual Enrollment Period rather than assuming it will auto-renew the same way.
