What is Part D?
Medicare Part D helps pay for prescription drugs. It’s offered by private insurance companies approved by Medicare.
You can get Part D as a stand-alone drug plan alongside Original Medicare and a Medicare Supplement, or as part of a Medicare Advantage plan that includes drug coverage.
How it works
- Formulary: each plan has its own list of covered drugs.
- Tiers: drugs are grouped into tiers, and lower tiers usually cost less.
- Pharmacies: plans often have preferred pharmacies with lower prices.
- Yearly cap: in 2026, your out-of-pocket costs for covered drugs are capped at $2,100 for the year.
Avoiding the late penalty
If you go too long without Part D or other creditable drug coverage after you’re first eligible, you may owe a late enrollment penalty for as long as you have Part D. That’s true even if you don’t take many medications today.
What to compare each year
- Whether all of your prescriptions are covered
- Your total yearly cost: premium plus what you pay for your drugs
- Your pharmacy’s pricing
Plans change every year, so it’s worth reviewing yours during the Annual Enrollment Period, October 15 to December 7. Bring your medication list and we’ll compare plans for you.
