Medicare With VA or TRICARE: How They Work Together

If you have TRICARE and qualify for Part A, you must also have Part B to keep TRICARE coverage. With VA health care, Medicare is your choice. Still, signing up for Part B when first eligible avoids a late penalty that lasts as long as you have Part B.

Key takeaways

• VA care and Medicare do not work together on one bill. The VA pays for VA care, and Medicare pays for care outside the VA.
• With TRICARE, Part A and Part B turn your coverage into TRICARE For Life at 65.
• VA coverage is not job-based coverage, so delaying Part B can bring a late penalty.
• VA and TRICARE drug coverage both count as creditable drug coverage, so many people skip Part D.
• Plan details for Medicare Advantage, Part D and Medigap vary by location and carrier.

How do VA care and Medicare work together?

The VA and Medicare are separate programs. They do not split a bill the way two insurance plans can. Each one pays for its own kind of care.

The VA pays for care you get at a VA facility, or from a community doctor the VA approves first. Medicare pays for care from doctors and hospitals outside the VA that accept Medicare. If you go to a non-VA doctor without VA approval, the VA usually will not pay.

Having both gives you choices. You can use the VA for some care and a local doctor or hospital for other care. This can matter in an emergency, or if the nearest VA facility is far from home.

Should veterans sign up for Part B?

Part B is optional with VA care, but the VA encourages veterans to enroll. VA health benefits depend on your priority group (the VA's ranking of veterans for care) and on VA funding. They can change over time.

VA coverage does not let you delay Part B without a penalty. The Part B late penalty adds 10% to your premium for each full 12-month period you could have had Part B but did not. You pay it for as long as you have Part B.

Here is one case. If you wait 2 full years, your penalty is 20%. With the 2026 standard Part B premium of $202.90, that is about $40.60 more a month in 2026. The premium is set each year, so the penalty changes with it.

If you choose to wait, you can sign up later during the General Enrollment Period, January 1 to March 31. Coverage starts the month after you sign up. For every window, see Medicare enrollment periods.

Do veterans need a Part D plan?

VA drug coverage counts as creditable drug coverage (drug coverage at least as good as Medicare's). So you can skip Part D while you have VA drug coverage, with no Part D penalty later.

Some veterans join Part D anyway. The VA usually fills only prescriptions written by VA doctors. A Part D plan can help with drugs from a non-VA doctor at a local pharmacy.

If you ever leave VA drug coverage, join a Part D plan within 63 days. A longer gap can bring a Part D late penalty. Our guide to avoiding Part D late penalties shows how it is figured.

What is TRICARE For Life?

TRICARE is health coverage for military retirees, service members and their families. When a TRICARE member gets Part A and Part B, their coverage becomes TRICARE For Life. This usually happens at 65.

TRICARE For Life works like a supplement. Medicare pays first for care that both cover. TRICARE For Life then pays its share of what is left.

In 2026, you still pay the standard Part B premium of $202.90 a month; it is set each year. TRICARE For Life itself has no enrollment fee.

Must you keep Part B with TRICARE?

Yes, in most cases. If you qualify for Part A with no premium, you must have Part B to keep TRICARE. Without Part B, TRICARE coverage ends.

There is one main exception. If your spouse or you are on active duty, you can delay Part B. You get a special enrollment period (a sign-up window outside the usual ones) to enroll later. It lasts 8 months after active duty ends or TRICARE coverage based on it ends.

This rule also covers people under 65. Someone who gets Medicare because of a disability and has TRICARE must have Part B too.

How do VA and TRICARE compare?

The main difference is Part B. With TRICARE, Part B is required. With VA care, Part B is your choice, but waiting can raise your premium for as long as you have Part B.

Some people have both VA care and TRICARE For Life. They can use either, and they still need Part B to keep TRICARE.

Do you need Medigap or Medicare Advantage?

Many people with TRICARE For Life do not buy a Medigap policy (private insurance that helps pay Original Medicare's costs). TRICARE For Life already pays much of what Medicare leaves, such as the 2026 Part B deductible of $283.

Veterans with VA care may still look at Medigap or a Medicare Advantage plan. These can help pay for care outside the VA. Premiums, networks and costs vary by plan, location and carrier.

If you travel or live abroad, rules differ. Medicare usually does not pay outside the U.S., but TRICARE For Life can. See Medicare Away From Home for details.
