Medicare Part D

Still Have Drug Coverage at Work or the VA? Read This First

Kingsport, Tenn. — If you're approaching 65 in the Tri-Cities and already have prescription drug coverage through a job, a spouse's plan, a union, the VA, or TRICARE, you've probably wondered whether you need to sign up for Medicare Part D right away. The short answer: not always. What matters is whether your current drug coverage is considered "creditable" — and whether you have the paperwork to prove it.

Key takeaways

Creditable drug coverage is coverage Medicare considers at least as good as a standard Part D plan, and it lets you delay Part D without a lifetime penalty.
VA, TRICARE, most Federal Employees Health Benefits plans, and many employer and union plans are typically creditable — but you should confirm in writing every year.
Your plan or benefits office must send you a Notice of Creditable Coverage each year, usually before Oct. 15; keep it in case Medicare asks for proof later.
If you lose creditable coverage, you generally have 63 days to enroll in a Part D or Medicare Advantage drug plan before a penalty can start adding up.

That single word, creditable, is what protects you from a lifelong late-enrollment penalty if you decide to join a Medicare drug plan later.

What "creditable" actually means

Medicare uses "creditable" to describe drug coverage that is expected to pay, on average, at least as much as a standard Medicare Part D plan would. If your current coverage meets that bar, Medicare treats it as a fair substitute for Part D. You can stay on it, skip Part D for now, and enroll later when you actually need to — with no late-enrollment penalty attached.

If your coverage is not creditable and you go 63 days or more without Part D, a penalty begins building. It's small each month, but it's permanent once it starts. That's why the label matters.

Coverage that is usually creditable

Most of the following typically counts as creditable, though you should always confirm with the plan itself:

Employer or union group health plans with drug benefits, including retiree coverage
VA prescription benefits for enrolled veterans
TRICARE (including TRICARE for Life)
Federal Employees Health Benefits (FEHB) plans
Indian Health Service coverage
Some COBRA plans (check the notice — not all COBRA drug coverage is creditable)

Kingsport is in Sullivan County, and many local retirees carry coverage from Eastman, the state of Tennessee, a former federal job, or military service. Any of those can be creditable, but "usually" isn't "always." Ask.

The notice that proves it

Once a year — generally before the Annual Enrollment Period begins on Oct. 15 — your plan is required to send you a Notice of Creditable Coverage. It's a plain letter or email that says, in essence, "Yes, this coverage is creditable" (or, sometimes, "No, it isn't").

Keep it. File it with your Medicare paperwork. If you ever enroll in Part D later, Medicare may ask you to prove you had creditable coverage for the years you delayed. Without the notice, you may end up owing a penalty you didn't earn.

If you didn't get one for 2026, call your benefits office or plan administrator and request it.

When you should still look at Part D

Even if your coverage is creditable, it's worth a second look during Medicare's Annual Enrollment Period (Oct. 15 – Dec. 7). A few reasons:

Your employer or retiree plan's drug benefit could change in 2027.
You may be paying more for a group plan than a stand-alone Part D plan would cost.
Part D has real consumer protections worth knowing about: an annual out-of-pocket cap on covered drugs of $2,100 in 2026 and $2,400 in 2027, a maximum deductible of $615 in 2026 and $700 in 2027, and the elimination of the old "donut hole" coverage gap. There's also the Medicare Prescription Payment Plan, which lets you spread drug costs across the year in monthly installments.

Higher earners should also know that Part D can carry an income-related surcharge (IRMAA) starting above $109,000 in income for a single filer in 2026. That doesn't apply to VA or employer drug coverage.

What to do if you lose creditable coverage

If you retire, age off a spouse's plan, or your employer drops drug coverage, you generally have a 63-day window to enroll in a Medicare Part D plan or a Medicare Advantage plan that includes drug coverage. Miss it, and the late-enrollment penalty clock starts.

This is a Special Enrollment Period — you don't have to wait for October. But you do have to act.

Good to know

Frequently asked questions

Is VA prescription coverage creditable for Medicare Part D?

Yes. VA drug coverage is considered creditable, so veterans enrolled in VA health care can generally delay Part D without a late-enrollment penalty. Some veterans still choose to enroll in a Part D plan for access to non-VA pharmacies; that's a personal call. Check with the VA if you're unsure of your status.

What happens if I never got a Notice of Creditable Coverage?

Call your plan or benefits administrator and ask for one. Plans are required to send the notice at least once a year and any time coverage changes. If you enroll in Part D later, Medicare may ask for proof, and that notice is the easiest way to show you weren't uncovered.

How is the late-enrollment penalty calculated?

Medicare adds roughly 1% of the national base Part D premium for every full month you went without creditable drug coverage after becoming eligible. The penalty is added to your Part D premium for as long as you have Medicare drug coverage — it doesn't go away.

Can I keep my employer drug plan and also join Part D?

Sometimes, but it can backfire. Some employer and retiree plans will drop you (and your dependents) from all coverage if you enroll in Part D. Always ask your benefits office before signing up for a Medicare drug plan on the side. --- For personalized help, start at **medicare.gov**, call **1-800-MEDICARE**, or reach out to the Tennessee SHIP for free counseling. When it comes to creditable coverage, a five-minute phone call today can save you a penalty that lasts the rest of your life on Medicare.
