If you're a veteran or military retiree approaching 65 — or already there — figuring out how Medicare works with your VA health care or TRICARE For Life can feel like nobody gives you a straight answer. This page is the plain-language version, written for San Diego County veterans, with the mistakes to avoid up front.
A quick note before anything else: the goal here is to help you understand your own coverage, not to talk you into a plan. For a lot of veterans, what you already have is excellent. Let's walk through it.
VA health care and Medicare: they don't coordinate
This is the part that surprises people most. VA benefits and Medicare do not work together as primary and secondary insurance. They're two separate systems:
- The VA covers care you get at VA facilities.
- Medicare covers care you get outside the VA — a local specialist, a non-VA hospital, an emergency room while traveling.
You essentially choose which system to use for a given visit. Having both simply gives you more places you can go.
The Part B mistake that costs veterans for life
Here's the trap: VA health care is not considered creditable coverage for Medicare Part B. That means if you skip Part B at 65 because "I've got the VA," you can be hit with a late-enrollment penalty — and it's not a one-time fee. It's added to your Part B premium for as long as you have Medicare, and it grows the longer you wait.
Most veterans should enroll in Part B when first eligible. VA coverage alone doesn't protect you from the penalty, and it doesn't help you at the non-VA doctors and hospitals Part B is built for.
The one thing the VA does cover you on: prescriptions
Good news on the drug side. VA prescription drug coverage is considered creditable for Medicare Part D. If you get your medications through the VA, you can delay or skip a standalone Part D drug plan without a penalty, as long as you keep your VA drug coverage.
That single fact is why many veterans look at MA-only plans — Medicare Advantage plans that don't include built-in drug coverage. If your prescriptions are already handled by the VA, you may not need to pay for drug coverage twice. (More on the trade-offs below.)

TRICARE For Life and Medicare
If you're a military retiree with TRICARE For Life (TFL), the rules are different — and there's one you can't ignore.
You must have both Medicare Part A and Part B to keep TRICARE For Life. If you don't enroll in Part B, or you drop it later, you lose TFL entirely. There's no separate TFL premium — the Part B premium is your only cost to keep it active.
When you have both, TFL works as wraparound coverage: Medicare pays first, TFL pays second, and for most Medicare-covered services that combination leaves you with little or nothing out of pocket. On the prescription side, TRICARE's pharmacy coverage is creditable too, so TFL beneficiaries generally don't need a separate Part D plan.
Do veterans need a Medicare Advantage plan?
Honestly? Not always — and any agent worth their salt will tell you that.
For many TRICARE For Life retirees, Original Medicare plus TFL is already comprehensive, low-cost coverage with wide provider access. A Medicare Advantage plan can be layered on, but it isn't automatically an upgrade, and it can introduce network restrictions you don't have today.
For VA-only veterans, the picture is different. Some choose an MA-only plan to get the medical coverage and extra benefits some plans offer for care outside the VA, while keeping the VA for prescriptions and routine care. The important caveats: Medicare Advantage plans use provider networks, so you'd want to confirm your non-VA doctors are in-network first, and remember that VA and Medicare Advantage still don't coordinate — you pick which one to use per visit.
There's no one right answer. It depends on your doctors, your medications, how much you rely on the VA, and what you want. That's exactly the kind of thing worth reviewing with someone who does it every day.

Frequently asked questions
Do veterans need Medicare if they have VA benefits?
Most should still enroll in Medicare Part B at 65. VA health care and Medicare don't coordinate, and VA coverage is not creditable for Part B — so skipping Part B can lead to a lifelong penalty and leaves you without coverage for non-VA care.
Do I need Medicare Part D if I get my prescriptions from the VA or TRICARE?
Generally no. VA and TRICARE drug coverage are both considered creditable, so you can delay or skip a standalone Part D plan without penalty as long as you keep that coverage.
Can I lose TRICARE For Life?
Yes — if you don't have Medicare Part A and Part B. Part B is required to keep TFL. If you drop Part B, you lose TRICARE For Life.
Can a veteran have both VA benefits and a Medicare Advantage plan?
Yes, but they don't coordinate. You'd use the VA for VA care and the Medicare Advantage plan for care in its network. Check that your non-VA doctors are in-network before enrolling.
