Why CHAMPVA Claims Are Denied or Delayed—and What to Do

Quick answer

A CHAMPVA claim can be delayed or denied for very different reasons, and the right fix depends on what VA actually says on the Explanation of Benefits (EOB) or letter.

Do not automatically submit the same claim again or jump straight to an appeal. First identify whether the problem is missing information, a billing or coding error, other health insurance (OHI), eligibility, a filing deadline, preauthorization, coverage or medical necessity, a duplicate submission, or a provider payment issue.

VA's current CHAMPVA claim instructions say routine claim processing takes about 90 days. If VA needs more information, it sends an EOB or letter explaining what is needed. If VA decides it cannot cover the claim and you disagree, that is when a decision review may be appropriate.

A useful first distinction is:

What VA tells you	What it usually means	Best next step
More information or documents are needed	The claim record is incomplete	Send the requested information as a resubmission for the existing claim
OHI information or an OHI EOB is missing	CHAMPVA cannot finish coordination of benefits	Update OHI information and submit the required EOBs
The claim is a duplicate	VA matched it to a previously processed claim	Do not resubmit again unless VA instructs you to
VA cannot cover or pay the claim and you disagree	VA made an adverse decision	Review the decision and use the appropriate current decision-review option

The most common reasons CHAMPVA claims are delayed or denied

VA publishes a current family member claim denial-code guide that identifies common problems and what to do about them. Your EOB is the best starting point because it ties the reason to your specific claim.

1. Other health insurance information is missing, incomplete, or outdated

CHAMPVA is generally secondary when a beneficiary has other health insurance. VA's current CHAMPVA Care guidance says the other plan should usually process the claim first and its EOB should be sent with the CHAMPVA claim.

Common denial-code examples include:

• 78 — an EOB from other insurance is required;
• 218 / 220 — OHI information is missing or incomplete; and
• 278 — more than one primary insurance plan is on file and EOBs are needed from each.

VA also says it reviews claims for OHI information and may stop claim payments when required OHI information is not being supplied or when a new OHI plan has been reported but not fully documented.

What to do: Make sure the other insurer has adjudicated the claim, gather the matching EOB or EOBs, and update CHAMPVA's OHI record when coverage has changed. See How CHAMPVA Works With Other Health Insurance.

2. The claim is missing billing, coding, or medical documentation

VA's claim instructions require enough information to identify the patient, provider, services, charges, diagnosis, and procedures. For beneficiary reimbursement claims, the itemized billing statement should include the diagnosis code and either CPT or HCPCS procedure coding in addition to the other required billing information.

VA's provider guidance also warns that claims can be delayed by incomplete provider identifiers or addresses, mismatched patient information, incomplete OHI attachments, missing surgery codes, and billing-format problems.

Common denial-code examples include:

• 224 — additional medical documentation is required; and
• 391 — the diagnosis code is invalid or missing.

What to do: Correct the missing information and resubmit it with the CHAMPVA EOB or request letter so VA can match the new material to the existing claim. If VA is asking for missing information, use the process in How to Resubmit a CHAMPVA Claim With Missing Information.

3. Eligibility does not match the date of service

Denial code 137 means VA's record shows that the beneficiary was not eligible for CHAMPVA on the date of service.

That can be a true eligibility problem, or it can be a date or record issue that needs correction. Eligibility is separate from whether the service itself is covered.

What to do: Verify the beneficiary's CHAMPVA eligibility for the exact date of service. If the eligibility record is wrong, address that record before repeatedly resubmitting the same medical claim.

4. VA identifies the submission as a duplicate claim

Denial codes 65, 159, and 177 are used for duplicate claims. VA specifically warns not to resubmit a duplicate again unless instructed, because another submission can simply produce another denial.

What to do: Compare the EOB's related claim information with the claim you submitted. If you believe VA matched the wrong claim, use the contact route shown by VA rather than sending another identical claim.

5. The claim was filed outside the applicable filing period

Denial code 124 signals a timely-filing problem. The governing rule is 38 CFR § 17.276.

For most non-inpatient care, the ordinary filing deadline is one year after the date of service. For inpatient care, the ordinary deadline is one year after discharge. The regulation also contains special 180-day rules for certain retroactive approvals and a written good-cause exception that VA reviews case by case.

What to do: Do not assume every claim uses the same clock. Identify which filing rule applies before deciding whether the denial is correct. See CHAMPVA Claim Filing Deadlines: 1-Year and 180-Day Rules.

6. Required preauthorization was not obtained

Most CHAMPVA care does not require advance authorization, but some categories do. VA currently identifies inpatient mental health care, substance-use treatment, limited covered dental care, and organ transplants among the categories requiring approval.

Under 38 CFR § 17.273, a missed required preauthorization does not always end the analysis. When CHAMPVA is the responsible payer and the claim is timely, the regulation provides for retrospective medical-necessity review in specified circumstances.

What to do: First confirm that the service actually required CHAMPVA preauthorization. If the care already occurred, review Missed CHAMPVA Preauthorization: What Happens Next?.

7. The service is excluded, not covered for the diagnosis, or not medically necessary

VA's denial-code guide includes:

• 27 — the billed service is not covered for the diagnosis submitted; and
• 148 — the billed service is not covered under CHAMPVA.

Separately, 38 CFR § 17.272 limits CHAMPVA payment for excluded services and services that do not meet the program's medical-necessity requirements.

A diagnosis-code mistake and a true coverage exclusion are not the same problem. A missing or incorrect code may be correctable; a true adverse coverage determination may require a decision review if you disagree.

8. The provider has a payment or EFT setup problem

VA's denial-code page lists CARC 299 / RARC N24 when payment requires Electronic Funds Transfer enrollment. VA instructs the provider to enroll in EFT and not resubmit the claim.

This is a good example of why repeated claim submissions can make troubleshooting worse: the claim itself may not be the part that needs correction.

A 5-step troubleshooting process

Step 1: Read the EOB or letter before doing anything else

Record:

• the claim or reference information;
• date or dates of service;
• provider;
• denial or remark code;
• the exact reason VA gives; and
• any document or action VA requests.

If you need help reading the fields, use How to Read a CHAMPVA Explanation of Benefits.

Step 2: Decide whether VA needs more information or has actually made an adverse decision

This distinction matters.

VA's current family-member review guidance says a decision review is not required just to submit missing documentation, an OHI EOB, or proof of payment. Those are completion or resubmission issues.

By contrast, VA's claim page says that when VA decides it cannot cover the claim and you disagree, you can request a decision review.

Step 3: Fix the underlying problem instead of creating a new one

Use the reason on the EOB:

• Missing OHI: submit the adjudicated EOB or EOBs and update OHI information if needed.
• Missing documents: send the requested medical or billing records with the EOB or request letter.
• Coding error: have the provider correct the required diagnosis or procedure information and resubmit as directed.
• Duplicate: do not send the same claim again unless VA instructs you to.
• EFT problem: the provider needs to correct payment enrollment, not duplicate the claim.

VA's provider page specifically says to include the CHAMPVA EOB when resubmitting a claim and warns that resubmitting with only a claim number may delay processing.

Step 4: Check filing, authorization, eligibility, and coverage separately

These four questions answer different things:

1. Was the beneficiary eligible on the date of service?
2. Was the claim filed on time?
3. Did the service require preauthorization, and if so, what review applies now?
4. Was the service otherwise covered and medically necessary?

A claim can pass three of these tests and still fail the fourth. Keeping them separate makes it easier to identify what actually needs to be fixed.

Step 5: Use decision review for a real disputed decision

If the issue is simply missing evidence, OHI, or proof of payment, send the missing material.

If VA made an adverse payment or coverage decision and you disagree, follow the current VA decision-review and appeal guidance for family member care and the instructions on the decision or EOB. The correct review route depends on what you are disputing and whether you are adding new evidence.

Claim-prevention checklist for beneficiaries

Before a claim is filed or resubmitted, confirm that:

• the beneficiary name and date of birth match CHAMPVA records;
• the date of service falls within the beneficiary's eligibility period;
• the provider bill is itemized rather than a simple balance statement;
• the bill includes diagnosis and procedure information required by VA;
• any applicable OHI has processed the claim first;
• every required OHI EOB is included;
• the claim is within the applicable filing deadline;
• any required preauthorization issue has been addressed; and
• you are responding to the specific EOB or letter rather than sending a blind duplicate.

Claim-prevention checklist for provider offices

VA's current provider guidance highlights several details that can prevent processing problems:

• include the complete nine-digit EIN/TIN;
• include both the billing address and physical service address;
• use the patient's legal name and accurate identifying information;
• make sure attachments match the patient and claim;
• include adjudicated EOBs from all applicable primary and secondary insurance plans;
• make sure the EOBs account for all billed services;
• use complete diagnosis and procedure coding; and
• when resubmitting, include the CHAMPVA EOB.

When the EOB reason still does not make sense

Do not guess from the word “denied” alone. A claim can be held for missing OHI, returned for documentation, rejected as a duplicate, denied for filing limits, or denied on substantive coverage grounds. Those outcomes require different responses.

Use the EOB code and the current VA guidance first. If the reason still appears inconsistent with the claim record, gather the EOB, billing documents, OHI EOBs, eligibility information, and relevant authorization records before contacting VA or choosing a formal review path.
