Quick Summary
Medicare Part D is optional, but going without Part D or other creditable prescription drug coverage can create a late enrollment penalty if you decide to enroll later.
Even if you don’t currently take prescription medications, Medicare recommends considering drug coverage when you’re first eligible.
If you go 63 consecutive days or more without Medicare drug coverage or other creditable prescription coverage after your eligible enrollment period, you may owe a Part D late enrollment penalty later.

What If You Don’t Take Any Medications?
This is one of the most common questions I hear.
You might think:
“I don’t take any prescriptions, so why should I pay for Part D?”
The problem is that you can’t always wait until you become sick and then immediately buy a plan.
Medicare drug plans have enrollment periods.
Going without coverage can also create a late enrollment penalty.
What Is Creditable Drug Coverage?
Creditable prescription coverage is coverage that’s expected to pay, on average, at least as much as standard Medicare drug coverage.
Examples may include certain coverage from:
- Current employer
- Former employer
- Union
- VA
- TRICARE
- Indian Health Service
Your current insurance should tell you whether your prescription coverage is considered creditable.
The 63-Day Rule
If you go:
63 consecutive days or more
without Part D or another source of creditable drug coverage after you’re eligible, you may owe a Part D late enrollment penalty when you eventually join.
Do You Need Part D With Medigap?
If you use:
Original Medicare + Medigap
you generally need to obtain prescription drug coverage separately if you want Part D.
Modern Medigap policies don’t include outpatient prescription drug coverage.
What If You Have Medicare Advantage?
Most Medicare Advantage plans include prescription drug coverage.
In many types of Medicare Advantage plans, you’re not permitted to add a separate standalone Part D plan.

Do You Really Need Medicare Part D?
Keith's Take
If you’re healthy and don’t take any medications, Part D can feel like insurance you’re paying for but not using.
But insurance is supposed to protect against what may happen later.
I usually don’t want someone going without Part D unless they have another source of creditable drug coverage and understand the rules.
A prescription you don’t need today can become very expensive six months from now.
