CHAMPVA pays the claim. Weeks later a bill shows up from the doctor's office anyway. Almost every CHAMPVA family hits this, and almost nobody is told the rule that settles it: a provider who accepts CHAMPVA has to take the CHAMPVA allowable amount as payment in full. The gap between what they charged and what CHAMPVA allowed is theirs to write off, not yours to pay. This guide shows you how to read the statement, check the math yourself, and handle a bill that should never have been sent.
The rule that settles most bills
A provider who accepts CHAMPVA cannot bill you the difference between their charge and the CHAMPVA allowable amount.
This is federal regulation, not a courtesy. CHAMPVA prints it right on the statement, in the remark that reads CFR 17.272(b)(3) requires provider to accept CHAMPVA allowable as full payment. You owe your deductible and your cost share. The write-off is the provider's problem.
Read that carefully, because there is one real exception further down: a service CHAMPVA does not cover at all is different from an amount CHAMPVA discounted. The first one can be your bill. The second one never is. Telling them apart is most of the work, and the next section does it.
What each column on the statement means
CHAMPVA's Explanation of Benefits is not a bill. It says "Information only, no check enclosed" near the top. It is a receipt for a decision. Here is what the columns are actually saying.
| Column | What it means | Is it yours to pay? |
|---|---|---|
| Amount Billed | What the provider's office charged. A wish, not a price. | No |
| Amount Allowed | The most CHAMPVA will recognize for that service. This is the real price, and every percentage below is figured on this number. | This is the basis |
| Amount Not Covered | The trap. It is two very different things added together: the discount between billed and allowed, and any service CHAMPVA does not cover. | Sometimes, see below |
| OHI Paid | What your other health insurance paid first. OHI means Other Health Insurance. | No |
| HAC Payments | What CHAMPVA itself paid the provider. | No |
| Cost Share | Your 25 percent of the allowable, after your deductible. | Yes |
| Deductible | $50 per person per calendar year, $100 per family, outpatient only. | Yes |
| Cat Cap Accrual | A running total of what you have paid this year toward the $3,000 family catastrophic cap. Watch this number. | Progress bar |
The single most misread column is Amount Not Covered. Split it in two:
- The discount. Provider charged $389, CHAMPVA allowed $149.13, so $239.87 is "not covered." That is the write-off. You do not owe it, and a provider who accepts CHAMPVA cannot chase you for it.
- A non-covered service. If a line item is flagged as a service CHAMPVA does not cover at all, such as routine eye exams, hearing aids, chiropractic care, or cosmetic work, that one genuinely can be billed to you. Our costs guide lists what is excluded.
If a bill arrives, this is the first question to answer: is the office chasing a discount, or a service CHAMPVA never covered?
Check the math yourself
Two minutes with a calculator settles most disputes, and our CHAMPVA Bill Checker will do it for you: enter the numbers off your statement and it tells you what you owe and whether the bill is right. To do it by hand, work only from the Amount Allowed.
Your share = any remaining deductible, plus 25 percent of what is left of the allowable.
Worked example. Allowable is $149.13, and you have already met your $50 deductible this year:
- 25 percent of $149.13 is $37.28. That is your cost share.
- CHAMPVA pays the other $111.85 to the provider.
- The provider charged $389. The $239.87 above the allowable is written off. Nobody pays it.
Same visit, but the deductible is not met yet. The first $50 of the allowable goes to your deductible, then 25 percent of the remaining $99.13 is $24.78. Your total that day is $74.78, which is exactly half the allowable. This is why people say their cost share "looks like 50 percent." It is not. It is the deductible landing all at once in January, and it does not repeat.
If the number on your statement is bigger than this math allows, the usual culprits are a non-covered line item, a deductible you had forgotten, or a claim processed in the wrong order when you have other insurance.
When you have other insurance too
CHAMPVA is almost always the payer of last resort. Your other insurance, including Medicare, pays first and CHAMPVA pays second. When that happens correctly, CHAMPVA usually picks up most or all of what the primary left behind, and the VA's own provider fact sheet says the beneficiary will normally have no cost share at all.
Two things go wrong here often enough to check for:
- The claim was billed to CHAMPVA first. If CHAMPVA paid nothing and the statement looks strange, ask the office which payer they billed first. Billed out of order, the claim gets denied or underpaid and has to be resubmitted.
- Your statement says OHI when you have no other insurance. That usually means CHAMPVA still has an old policy on file. It is fixed by updating your other-insurance information with the VA, and until it is fixed your claims will keep processing wrong.
One more rule worth knowing before you appeal anything: CHAMPVA prints that you must exhaust all appeal levels with your primary insurance before it will consider a claim for reimbursement. Fight it with the primary first, then bring CHAMPVA the paperwork.
The remark codes you keep seeing
The block of codes at the bottom of the statement is where the useful information hides. These are the ones CHAMPVA families see most:
| Provider must accept the allowable as full payment | The write-off rule. Quote this one when an office bills you the difference. |
| Charge exceeds the fee schedule or maximum allowable | The office charged more than the allowable. That excess is the write-off, not your bill. |
| Cost share may not always be patient liability | Other insurance or the catastrophic cap can wipe out the cost share shown. |
| Exhaust all appeals with your primary insurance first | CHAMPVA will not consider reimbursement until the primary has finished denying it. |
| Attach the CHAMPVA EOB when resubmitting | A resubmitted claim without the prior statement attached gets rejected again. |
| Service, equipment, or drug not covered under the current benefit plan | This is a genuine non-covered service. This one can be your responsibility. |
What to do when the office bills you anyway
Work in this order. Most of these end at step two.
- Compare the bill to the statement. If the office is asking for more than the cost share and deductible shown, and the line is not a genuinely non-covered service, the bill is wrong.
- Call the billing office, not the front desk. Say this: "CHAMPVA processed this claim. Your remittance shows the requirement to accept the CHAMPVA allowable as payment in full. I owe the cost share of $X. Please adjust the balance." Billers know this rule. Schedulers do not.
- Ask them to reprocess if the order was wrong. If they billed CHAMPVA before your primary insurance, the claim needs to go back in the right sequence with the primary's statement attached.
- Call CHAMPVA at 800-733-8387 and ask them to confirm the payment and the write-off in writing. Provider offices can verify eligibility any time at 888-820-1756.
- If it reaches a collection agency, send a written dispute rather than paying. Include a copy of the statement showing what CHAMPVA allowed and what your responsibility was. Do this in writing, keep a copy, and do not rely on a phone call. A balance that should have been written off is a billing error, and it is a great deal easier to unwind before it is reported than after.
If you already paid out of pocket
If your provider will not bill CHAMPVA at all, you can pay and file the claim yourself. Use VA Form 10-7959a, one form per claim, attached to an itemized bill. If you have other insurance, attach that statement too, because CHAMPVA needs to see what the primary paid before it will consider the balance.
File within one year of the date of care. Reimbursement checks are issued to the beneficiary named on the claim, which means a child's claim generates a check in the child's name. Most banks will deposit a minor's check into a parent's account, but call your branch first rather than finding out at the counter.

If you are reading this from the billing side
Same document, different question. If you are reconciling a remit rather than checking a bill, our guide to billing CHAMPVA covers the payer IDs, the secondary-payer order, the one-year filing deadline, and why the difference between your charge and the allowable cannot be billed to the patient.
When the real answer is a different provider
Sometimes the office understands the rule perfectly and simply will not follow it, or will not bill CHAMPVA at all. You are not required to keep paying for that. A provider who accepts CHAMPVA and accepts the allowable amount as payment in full costs you 25 percent of a controlled rate and nothing more.
Search verified local providers by state and city or by specialty, then ask one question before you book: will you bill CHAMPVA and accept the allowable amount as payment in full? A yes from the billing office is worth more than a yes from anyone else in the building.
Common questions
Can a doctor bill me the difference between their charge and what CHAMPVA allowed?
No. Federal regulation requires a provider who accepts CHAMPVA to accept the CHAMPVA allowable amount as payment in full, and CHAMPVA prints that requirement on the statement itself. You owe your deductible and your 25 percent cost share. The amount above the allowable is written off.
What does Amount Not Covered mean on a CHAMPVA EOB?
It combines two different things: the discount between what the provider charged and what CHAMPVA allowed, which is written off and is not your bill, and any service CHAMPVA does not cover at all, which can be your responsibility. Check which one the line item is before paying anything.
Why is my cost share more than 25 percent?
Almost always the deductible. The first $50 per person each year comes out before the 25 percent is figured, so an early-in-the-year visit can look close to half the allowable. It does not repeat once the deductible is met.
Why does my EOB say OHI when CHAMPVA is my only insurance?
OHI means Other Health Insurance, and it usually means CHAMPVA still has an old policy on file for you. Update your other-insurance information with the VA, because until you do, claims will keep processing as though something else should pay first.
A CHAMPVA bill went to collections. What do I do?
Dispute it in writing rather than paying, and include a copy of the CHAMPVA statement showing the allowable amount and your actual responsibility. If the balance was an amount the provider was required to write off, it should never have been billed to you at all. Keep copies of everything.
Is the CHAMPVA EOB a bill?
No. It says information only, no check enclosed. It is a record of how CHAMPVA processed the claim. The only numbers on it you may owe are the deductible and the cost share.
