Costs & coverage

Do I need Part D if I don't take any drugs?

Usually yes — it's the smart move even if you take no medications today. If you go 63 days or more without Part D or other creditable drug coverage after you're first eligible, you'll face a permanent late-enrollment penalty when you do sign up. A low-premium plan now protects you from that and from surprise drug costs later.

The penalty is the real reason

Medicare wants people to keep continuous drug coverage. If you skip Part D and later go 63 days or more without creditable coverage, a permanent surcharge gets added to your premium when you finally enroll — and it grows the longer you waited. Enrolling on time, even in an inexpensive plan, avoids that for good.

Health changes

Most people don't take regular medications until they do. A new diagnosis can mean an expensive prescription overnight, and without a plan you'd pay full price and might have to wait for the next enrollment window to get covered.

The exceptions

If you have creditable drug coverage elsewhere — often through an employer or union plan — you can keep that instead and avoid the penalty; just confirm in writing that it counts. And if you choose a Medicare Advantage plan, drug coverage is usually built in. A licensed agent can find a low-cost Part D plan or confirm your existing coverage qualifies.
