If you have CHAMPVA and Medicare is on the horizon, the good news is that the two are built to work together. You do not have to choose between them. But there is one rule you cannot afford to miss: once you are eligible for Medicare, you must keep both Part A and Part B, or you can lose CHAMPVA entirely. This guide walks you through how the two coordinate, who pays first, what you owe, and the proof you will need to show, so nothing about your coverage catches you off guard.
First, what CHAMPVA is, and what it is not
CHAMPVA, the Civilian Health and Medical Program of the Department of Veterans Affairs, is a health benefits program for eligible spouses, dependents, and survivors of veterans who are rated permanently and totally disabled from a service-connected condition, or who died from a service-connected condition. Certain other categories of family members may also qualify.
Two distinctions matter, because they are easy to confuse and the rules are not the same for each. CHAMPVA is administered by the VA, but it is separate from the VA health care the veteran receives for themselves, and it is separate from TRICARE. If your situation involves the veteran's own VA coverage, Medicare and VA benefits is the guide that speaks to that. This guide is about your CHAMPVA coverage and how it lines up with your Medicare.
You must keep both Part A and Part B
This is the rule to hold onto above all others. If you are eligible for Medicare, for any reason and at any age, you must have both Medicare Part A and Part B to get or keep CHAMPVA. This applies whether you reach Medicare through age or through disability before 65.
The reason this matters so much is the consequence of getting it wrong. Because CHAMPVA requires Part B once you are Medicare-eligible, dropping Part B, or never enrolling in it, can cause you to lose CHAMPVA. People sometimes consider skipping Part B to avoid its monthly premium, not realizing that the choice can quietly cost them their CHAMPVA benefits too. If you are weighing when and how to enroll, Medicare enrollment periods covers the timing so you can sign up on schedule and avoid a gap.
Medicare pays first, CHAMPVA pays second
When you have both, the order of payment is set: Medicare is the primary payer, and CHAMPVA is the secondary payer. Medicare pays for your care first. Then, for services that CHAMPVA covers, CHAMPVA may cover costs you still owe, such as your Medicare deductibles and coinsurance.
In practice, this makes CHAMPVA function much like supplemental coverage sitting on top of Medicare. This secondary-payer arrangement is the same kind of coordination Medicare uses with other coverage you might have; if you want the broader picture of how Medicare decides who pays first, see coordination of benefits. The takeaway for you is simple: Medicare goes first, and CHAMPVA can help with what is left over on covered services.
| Question | How it works with CHAMPVA and Medicare |
|---|---|
| Do I need Part A and Part B? | Yes. Once you are Medicare-eligible, for any reason at any age, you must have both Part A and Part B to keep CHAMPVA. |
| Who pays first? | Medicare pays first. CHAMPVA is the secondary payer. |
| What does CHAMPVA cover after Medicare? | For CHAMPVA-covered services, costs you still owe, such as Medicare deductibles and coinsurance. |
| Who pays the Part B premium? | You do. CHAMPVA does not pay your Medicare Part B premium. |
| What proof do I need at 65? | Proof of your Medicare coverage. If you are not eligible for premium-free Medicare, a notice of disallowance from the Social Security Administration. |
CHAMPVA does not pay your Part B premium
It is worth being plain about this, because the surprise can sting. CHAMPVA does not pay your Medicare Part B premium. You are responsible for paying that monthly premium yourself, just as any other person on Medicare would.
That is the trade at the heart of keeping both coverages: Part B is required to keep CHAMPVA, and you carry the Part B premium yourself. CHAMPVA's help comes on the back end, after Medicare has paid, in the form of covering deductibles and coinsurance you would otherwise owe on covered services.
The proof you must show at 65
When you turn 65, the VA needs to confirm your Medicare status to keep your CHAMPVA benefits in place. There are two paths, depending on whether you qualify for premium-free Medicare.
If you are eligible for premium-free Medicare, you provide the VA with proof of your Medicare coverage. If you are not eligible for premium-free Medicare at 65, you must instead provide a document called a notice of disallowance from the Social Security Administration, showing that you do not qualify for it. Either way, the point is the same: the VA confirms your Medicare situation, and your CHAMPVA continues. Knowing which document you need before your 65th birthday arrives is the easiest way to keep your coverage uninterrupted.
Frequently asked questions
Yes. Once you are eligible for Medicare, for any reason and at any age, you must have both Medicare Part A and Part B to get or keep CHAMPVA. Dropping Part B, or never enrolling in it, can cause you to lose your CHAMPVA benefits, so keeping Part B is not optional once you are Medicare-eligible.
Medicare pays first. CHAMPVA is the secondary payer, so after Medicare pays, CHAMPVA may cover costs you still owe, such as Medicare deductibles and coinsurance, for CHAMPVA-covered services. This makes CHAMPVA work much like supplemental coverage on top of Medicare.
No. CHAMPVA does not pay your Medicare Part B premium. You pay the monthly Part B premium yourself. CHAMPVA's role is to help with the deductibles and coinsurance you still owe after Medicare pays, on services CHAMPVA covers.
When you turn 65, you must give the VA proof of your Medicare coverage to keep CHAMPVA. If you are not eligible for premium-free Medicare at 65, you instead provide a notice of disallowance from the Social Security Administration, showing that you do not qualify for premium-free Medicare.
