The short answer
Whether a veteran needs a Medigap plan depends on the other coverage you have. If you have TRICARE for Life, it works much like a supplement already — it pays after Medicare for covered care — so an additional Medigap plan is usually unnecessary. If you rely on VA health care, the picture is different, because VA coverage doesn't help outside the VA system.
So the answer hinges on which military-related coverage you have and how you use civilian care.
TRICARE for Life and Medicare
TRICARE for Life is available to Medicare-eligible military retirees who have Part A and Part B, and it acts as a secondary payer to Medicare, covering much of what Medicare leaves. Because it fills those gaps, most people with TRICARE for Life don't also need a Medigap plan — that would generally duplicate coverage.
The key requirement is keeping Part B, since TRICARE for Life works with Medicare. Our guide to VA benefits and Medicare covers how these programs coordinate.
VA health care and Medicare
VA health care is excellent within the VA system but doesn't cover care you get from civilian providers outside the VA. So if you want the freedom to see non-VA doctors — for convenience, access, or specialty care — pairing Medicare with a supplement (or an Advantage plan) fills that gap. Many veterans keep VA care for some needs and Medicare-based coverage for others.
The right combination is personal. If you mostly use the VA, you may need little else; if you want civilian access, a supplement can make sense. Our Medicare Supplement overview explains how a supplement works.
Frequently Asked Questions
Do I need Medigap if I have TRICARE for Life?
Usually no. TRICARE for Life acts as a secondary payer to Medicare and fills most gaps, so an additional Medigap plan would generally duplicate coverage. Keeping Part B is the key requirement.
Do veterans with VA care need a Medicare supplement?
VA care doesn't cover civilian providers outside the VA. If you want to see non-VA doctors, a Medicare supplement (or Advantage plan) can fill that gap. If you use the VA for everything, you may need little else.
Should I keep Part B with military coverage?
For TRICARE for Life, yes — it requires Part B to coordinate with Medicare. With VA care, keeping Part B preserves flexibility to use civilian providers.
