Quick answer
CHAMPVA assignment is a billing agreement. When an authorized non-VA provider accepts assignment, the provider agrees to accept the CHAMPVA-determined allowable amount as payment in full for covered services and supplies. The beneficiary can still owe an applicable CHAMPVA deductible and cost share, but an assigning provider cannot bill the beneficiary for the difference between the provider's usual charge and CHAMPVA's allowable amount.
That is different from a provider who does not accept assignment. VA's current CHAMPVA care guidance says you may still receive care from such a provider, but you may need to pay the provider first, file your own claim, and pay any amount above the CHAMPVA allowable amount.
If a provider accepted assignment and later bills you for the difference between its billed charge and CHAMPVA's allowable amount, do not assume that excess amount is valid patient responsibility. Compare the bill with the CHAMPVA Explanation of Benefits (EOB), ask the billing office to review the assignment rules, and contact CHAMPVA if the issue is not corrected.
What accepting assignment means
The CHAMPVA regulation defines accepted assignment in 38 CFR § 17.270.
In practical terms, assignment means that the provider:
- accepts the CHAMPVA-determined allowable amount as full payment for the covered service or supply;
- bills CHAMPVA for the covered care; and
- may collect the beneficiary's applicable deductible and cost-share amounts, but not the difference between the provider's normal charge and the CHAMPVA allowable amount.
VA's current CHAMPVA Guidebook gives the same instruction: a provider that accepts assignment cannot bill the beneficiary for the difference between the allowable amount and what the provider normally charges.
This is why it is useful to ask a provider before care:
Do you accept CHAMPVA assignment and bill CHAMPVA directly?
That question is more precise than asking only whether the office "takes CHAMPVA."
For more on the difference between provider access and assignment, see Does CHAMPVA Have a Provider Network?.
The allowable amount is not the provider's sticker price
Under 38 CFR § 17.272(b), the CHAMPVA-determined allowable amount is the maximum level of payment CHAMPVA recognizes for a covered service or supply before applying deductible, cost sharing, or other health insurance.
A provider may bill a higher retail or usual charge. The important question is whether the provider accepted assignment.
If the provider accepted assignment
For a covered assigned service, the provider agrees to the CHAMPVA allowable amount as payment in full. The beneficiary's remaining liability is limited by the applicable CHAMPVA deductible and cost-share rules rather than the provider's higher billed charge.
If the provider did not accept assignment
VA says the beneficiary may still use the provider, but the financial risk is different. The beneficiary may have to pay the provider's full charge, submit a claim for reimbursement, and remain responsible for amounts above CHAMPVA's allowable amount.
The current CHAMPVA Guidebook says that when CHAMPVA is the beneficiary's only insurance, a non-assigning provider can require payment of the entire bill at the time of service. The beneficiary can then submit the itemized bill with a CHAMPVA claim. CHAMPVA reimbursement is based on the allowable amount, not necessarily the provider's full charge.
For the current filing process, see VA's How to file a CHAMPVA claim guidance.
What the regulation says about excess billing after assignment
Section 17.272(b) specifically excludes charges above the CHAMPVA-determined allowable amount from CHAMPVA coverage.
It also states that an authorized non-VA provider who accepts responsibility for the care of a CHAMPVA beneficiary agrees to accept the CHAMPVA allowable amount as full payment—that is, accepted assignment. The regulation says the provider's acceptance of that amount extinguishes the beneficiary's payment liability to the provider, subject to the applicable deductible and cost-share rules in the CHAMPVA definition of accepted assignment.
The regulation further states that attempts to collect an additional amount from the beneficiary may result in exclusion from federal benefits programs.
That regulatory consequence is administered by the government. A beneficiary does not need to decide whether a provider should face a federal sanction in order to challenge a bill. The practical first question is simply whether the provider accepted assignment for the service at issue.
Accepting CHAMPVA and accepting assignment are not the same question
CHAMPVA does not have a medical provider network. An office can be willing to see a CHAMPVA beneficiary while handling payment in different ways.
These questions therefore have different meanings:
| Question | What it tells you |
|---|---|
| Will you see a CHAMPVA beneficiary? | Whether the office is willing to provide care |
| Are you an authorized provider for this service? | Whether the provider meets CHAMPVA's qualification rules for the service |
| Do you accept CHAMPVA assignment? | Whether the provider agrees to accept the CHAMPVA allowable amount as payment in full, apart from applicable beneficiary cost sharing |
| Will you bill CHAMPVA directly? | Whether the office will submit the claim rather than require the beneficiary to seek reimbursement |
See What Counts as an Authorized CHAMPVA Provider? for the provider-qualification rules and CHAMPVA Key Terms in Plain English for a broader glossary.
What counts as balance billing in this context?
For this topic, balance billing means an assigning provider trying to collect the difference between:
- the provider's billed or usual charge, and
- the lower CHAMPVA-determined allowable amount.
Example: suppose a provider bills $300 for a covered service and CHAMPVA's allowable amount is $200. If the provider accepted assignment, the provider cannot treat the extra $100 simply as additional patient responsibility. The beneficiary may still owe a CHAMPVA deductible or cost share calculated under the program's rules, but the difference between $300 and the $200 allowable amount is not converted into a valid balance bill just because it appeared on the provider's statement.
This should not be confused with every bill a patient receives. A statement can also include legitimate patient responsibility, such as an applicable deductible or cost share, or charges tied to a service CHAMPVA did not cover. Those issues need to be reviewed separately.
What to do if an assigning provider balance bills you
1. Compare the provider bill with the CHAMPVA EOB
Start with the same date of service and compare:
- the provider's billed charge;
- the CHAMPVA allowable amount;
- the amount CHAMPVA paid;
- the deductible or cost share shown as patient responsibility; and
- the amount the provider is now asking you to pay.
The EOB is important because it shows how CHAMPVA adjudicated the claim. VA's current claim guidance says CHAMPVA sends an EOB explaining the covered amount and patient responsibility after a claim is processed.
2. Confirm whether the provider accepted assignment
Ask the billing office to confirm whether the provider accepted CHAMPVA assignment for the service.
If the provider did not accept assignment, a charge above the CHAMPVA allowable amount may be the beneficiary's responsibility. If the provider did accept assignment, the allowable amount is the payment-in-full ceiling for the covered assigned service, apart from the applicable deductible and cost share.
3. Ask the billing office to reprocess or correct the account
If the provider accepted assignment and the statement appears to bill the difference between the normal charge and CHAMPVA's allowable amount, give the billing office a copy of the CHAMPVA EOB and ask it to review the account under the CHAMPVA assignment rule.
You can point the office to:
- VA's CHAMPVA care page;
- the CHAMPVA Guidebook; and
- 38 CFR § 17.272(b).
The goal is to have the provider distinguish legitimate deductible or cost-share responsibility from an amount that should be adjusted off because the provider accepted assignment.
4. Contact CHAMPVA if the billing office will not correct the issue
VA's current provider guidance lists the VA Customer Call Center at 800-733-8387 for CHAMPVA questions. If the provider is unfamiliar with CHAMPVA, the Guidebook also directs providers to that number for program information.
When you call, have the relevant EOB, itemized bill, date of service, provider name, and any notes showing that the provider accepted assignment.
Do not ignore a bill that is approaching a provider deadline or collection action. Contact the billing office and CHAMPVA promptly so there is a record that the amount is being disputed and reviewed.
5. Keep the billing issue separate from a CHAMPVA claim decision
A provider balance-billing problem and a disagreement with CHAMPVA's own claim adjudication are not always the same thing.
If CHAMPVA denied a service, applied other health insurance incorrectly, or calculated the claim in a way you believe is wrong, the issue may require claim correction or a VA review process. If CHAMPVA processed the claim correctly but an assigning provider is trying to collect above the allowable amount, start with the provider's billing office and CHAMPVA's customer-service route.
What if the provider never accepted assignment?
If the provider did not accept assignment, current VA guidance says you can still receive care from that provider in many situations, but you should expect a different payment flow:
- You may need to pay the provider directly.
- You may need to submit the claim yourself.
- CHAMPVA calculates reimbursement from its allowable amount, not the provider's full billed amount.
- You can be responsible for charges above the CHAMPVA allowable amount.
If CHAMPVA is your only insurance, the Guidebook says the beneficiary should submit the provider's itemized bill with VA Form 10-7959a for reimbursement. Current VA claim guidance also explains the supporting documentation and direct-deposit requirements.
This is why confirming assignment before planned care can materially change your out-of-pocket exposure.
Medicare-participating hospitals have a specific inpatient rule
There is a specific rule for inpatient hospital services.
Under 38 CFR § 17.272(b), a Medicare-participating hospital must accept the CHAMPVA-determined allowable amount as payment in full for inpatient services provided to a CHAMPVA beneficiary. VA's Guidebook also states that Medicare-participating hospitals, and hospital-based health care professionals employed by or contracted to those hospitals, are required to accept CHAMPVA for inpatient hospital services.
That rule is narrower than saying every Medicare provider in every setting must accept CHAMPVA. The hospital rule is tied to inpatient services.
A short checklist before your next appointment
Before planned non-VA care:
- Ask whether the provider will see CHAMPVA beneficiaries.
- Ask specifically whether the provider accepts CHAMPVA assignment.
- Confirm whether the provider will bill CHAMPVA directly.
- If you have other health insurance, make sure the provider knows which plan pays first.
- Ask whether the specific service needs CHAMPVA preauthorization.
- Keep the EOB and itemized bill after the claim is processed.
The most important billing question is not simply "Do you take CHAMPVA?" It is "Do you accept CHAMPVA assignment?"
Bottom line
When a provider accepts CHAMPVA assignment, the provider agrees to accept CHAMPVA's allowable amount as payment in full for the covered assigned service, apart from the beneficiary's applicable deductible and cost share. The provider cannot turn the difference between its usual charge and the CHAMPVA allowable amount into an additional balance due from the beneficiary.
When a provider does not accept assignment, VA allows a different path: the beneficiary may pay the provider, file a claim, and remain responsible for amounts above the allowable amount.
If a bill looks inconsistent with assignment, compare it with the CHAMPVA EOB, confirm the provider's assignment status, ask the billing office to correct the account, and contact CHAMPVA at 800-733-8387 if the problem remains unresolved.
