The Tempting Logic — and the Trap
If you take no prescription drugs, paying for a Medicare Part D plan can feel like buying insurance for a problem you don't have. It's an understandable instinct. But Part D comes with a penalty structure specifically designed to discourage people from waiting until they're sick to sign up — and that penalty is permanent.
For most healthy 65-year-olds, the smart move isn't to skip Part D. It's to enroll in the cheapest available plan, accept a small monthly cost, and avoid a penalty that would follow you for life. Here's the math behind that.
How the Part D Late-Enrollment Penalty Works
If you go 63 or more days without Part D or other creditable drug coverage after your Initial Enrollment Period, Medicare adds a permanent penalty when you eventually enroll. The penalty is calculated as roughly 1% of the national base premium for every month you went without coverage — and it's added to your premium for as long as you have Part D. We break down the exact calculation in our Part D late-enrollment penalty guide.
The trap is that health changes. A 65-year-old on no medications may be on several by 72, and by then the penalty for those seven uncovered years is baked in permanently. Enrolling in a low-cost plan now is insurance against both future medications and the penalty itself.
The Case for a Cheap Plan Now
The practical strategy for someone with no current prescriptions is straightforward:
- Enroll in the lowest-premium Part D plan available in your county during your Initial Enrollment Period
- You'll pay a modest monthly premium, but avoid the lifelong penalty entirely
- You'll have coverage in place the moment a doctor prescribes something new
- Each year during Annual Enrollment, you can switch to a better-fitting plan as your medications change
- Remember the new $2,100 annual out-of-pocket cap protects you if you ever face high drug costs
The Exceptions Worth Knowing
There are legitimate reasons to skip a standalone Part D plan — but only if you have other creditable coverage. Veterans using VA pharmacy benefits, for example, have creditable drug coverage and can skip Part D without penalty (see VA benefits and Medicare). The same applies to some employer or retiree plans. The key is confirming in writing that your other coverage is 'creditable' — meaning at least as good as standard Part D.
If you're on a Medicare Advantage plan, drug coverage is usually built in, so you don't need a separate Part D plan. The one situation to avoid at all costs is having no creditable coverage and simply choosing to go without — that's the path to the permanent penalty. When in doubt, a quick review with a licensed advisor confirms whether you're covered or exposed, at no charge.
Frequently Asked Questions
What happens if I skip Part D and never take medications?
If you truly never need drugs, you'd pay premiums you didn't 'use' — but you'd also have coverage in place if that changed, and you'd avoid the lifelong late-enrollment penalty. Given how often medication needs arise with age, a cheap plan is usually the safer bet.
How much is the Part D penalty?
About 1% of the national base beneficiary premium for each full month you went without creditable coverage, added permanently to your premium. Ten years without coverage could roughly double your Part D premium for life.
Does VA drug coverage count instead of Part D?
Yes. VA pharmacy benefits are considered creditable coverage, so veterans using them can decline a standalone Part D plan without penalty. Keep documentation confirming it's creditable.
Can I add Part D later if I get sick?
You can, but generally only during specific enrollment windows (like Annual Enrollment), and you'll owe the late-enrollment penalty for the months you went without. You can't add it the moment you get a new prescription.
