    CHAMPVA and Medicare Before Age 65: Disability and Part B Rules

    If you get Medicare Part A before 65 through disability, ESRD, or ALS, you need Part B to keep CHAMPVA. Here's how it works and what to report.

    The short answer

    Getting Medicare before 65 doesn't end CHAMPVA. But if you're entitled to Medicare Part A, you must also enroll in Part B to keep CHAMPVA. If you cancel Part B, CHAMPVA ends the same day. Medicare Advantage counts. Then Medicare pays first and CHAMPVA second. Send VA your Medicare card and Form 10-7959c.

    What's the rule?

    38 U.S.C. 1781(d) and 38 CFR 17.271 say someone under 65 who's entitled to Part A must be enrolled in Part B to keep CHAMPVA. With both, CHAMPVA becomes secondary.

    Your Medicare statusWhat it means
    Not entitled to Part AThe Part B rule doesn't apply
    Part A and Part BYou keep CHAMPVA. Medicare pays first.
    Part A but not Part BYou don't meet CHAMPVA's Medicare rule
    Medicare AdvantageCounts as A and B. The plan pays first.

    The key date is when your Part A entitlement starts, not your age.

    Why would you get Medicare before 65?

    Usually through Social Security disability, end-stage kidney disease, or ALS. Medicare's before-65 page explains the timing for each.

    Don't cancel Part B

    The CHAMPVA Guidebook says if you cancel Part B, CHAMPVA ends the same day. For you, Part B isn't optional extra coverage. It's what keeps CHAMPVA.

    CHAMPVA doesn't pay your Part B premium.

    The June 5, 2001 grandfather rule only covers people who were already 65 then. It can't apply to anyone under 65 today.

    How do claims work?

    1. The provider bills Medicare first.
    2. Medicare processes it and usually forwards it to CHAMPVA.
    3. CHAMPVA pays what's left under its rules. VA's CHAMPVA care page says it may cover some or all of the Part B deductible.
    4. Check both EOBs.

    If you have job-based insurance too, it doesn't remove the Part B requirement. Ask Medicare and your plan which pays first. More here: CHAMPVA and Medicare.

    What do you send VA?

    VA Form 10-7959c and a copy of the front and back of your Medicare card.

    1. Check your Part A and Part B start dates on your card or award letter.
    2. Make sure Part B starts when Part A does.
    3. Send VA the form and card.
    4. Give providers both cards.
    5. Watch your first few EOBs.

    If the start dates don't match, call Medicare or Social Security and CHAMPVA right away.

    Other things that change

    • Part D isn't required. More here: CHAMPVA and Part D.
    • CITI care at VA facilities ends. VA says beneficiaries eligible for Medicare can't use CITI. Find a new provider before Medicare starts. More here: CHAMPVA CITI.
    • Medicare Advantage rules apply if you pick one, like networks and referrals.
