Insurance Claim Denied? A Guide for Veterans

Veterans have served their country and earned specific healthcare benefits in return. Yet VA healthcare denials, CHAMPVA rejections, and TRICARE disputes are common — and the appeal processes are often confusing, bureaucratic, and slow. Veterans also face unique challenges when claiming commercial insurance for conditions connected to military service, such as PTSD (ICD-10 F43.10), traumatic brain injury (ICD-10 S09.90XA/S09.90XD), military sexual trauma, and toxic exposure conditions recognized under the PACT Act of 2022. This guide explains the distinct appeal landscape for veterans across all major coverage programs and how to fight back effectively.

Why Veterans' Insurance Claims Get Denied

VA service connection denials. For VA disability compensation claims, the Department of Veterans Affairs denies benefits when it determines that the current condition is not connected to military service. Establishing service connection requires a current diagnosis, an in-service event, and a nexus linking the two. Nexus letters from physicians are often the critical missing element — and VA raters frequently discount inadequate or insufficiently detailed nexus letters.

PACT Act condition denials. The Sergeant First Class Heath Robinson Honoring our Promise to Address Comprehensive Toxics (PACT) Act of 2022 expanded presumptive service connection for veterans exposed to burn pits, Agent Orange, and other toxic substances. Despite this expansion, VA regional offices continue to deny PACT Act claims on incorrect procedural grounds. Veterans with qualifying toxic exposures should have presumptive service connection without needing to prove causation.

TRICARE Prior Authorization Denied: How to Appeal" class="auto-link">prior authorization and network denials. TRICARE (administered by the Defense Health Agency, DHA) denies claims for services provided without required prior authorization, services from out-of-network providers without referral, or services the TRICARE Medical Officer determines are not medically necessary. TRICARE's clinical criteria are published in the TRICARE Policy Manual, which is the relevant reference for TRICARE appeals.

CHAMPVA denials. CHAMPVA covers eligible dependents and survivors of permanently and totally disabled veterans. CHAMPVA denials commonly involve services excluded from CHAMPVA coverage (dental care, cosmetic procedures), coordination of benefits disputes when the beneficiary also has Medicare or other coverage, or claims that exceed CHAMPVA's allowable fees.

VA community care authorization disputes. Under the VA MISSION Act of 2018, veterans are eligible for community care (non-VA providers) when VA cannot provide the needed service within specified wait time or drive time standards. VA community care authorization denials — or failures to authorize care within the required timeframes — are a growing source of veteran appeals.

How to Appeal Veterans' Insurance Denials

Step 1: Identify the Specific Program and Appeal Pathway

The appeal process differs significantly by program. VA disability compensation: use VA Form 10-0998 (Notice of Disagreement) to initiate a Higher-Level Review, Supplemental Claim, or Board of Veterans' Appeals (BVA) appeal, depending on the evidence available. TRICARE: file a written appeal within 90 days of the denial through the TRICARE Regional Office or TRICARE contractor (Humana Military or HealthNet Federal Services, depending on your region). CHAMPVA: file a written appeal to the VA's CHAMPVA Center in Denver within 1 year of the denial.

Step 2: Obtain a Comprehensive Nexus Letter for VA Service Connection Disputes

For VA disability compensation denials, a strong nexus letter from a licensed physician — ideally a specialist in the relevant condition — is the most important element of an appeal. The letter must state: the veteran's current diagnosis, the specific in-service event or exposure, and the physician's medical opinion that the condition is at least as likely as not caused or aggravated by military service (the "at least as likely as not" standard under 38 CFR §3.102). Vague or conclusory nexus letters are routinely rejected by VA raters.

Step 3: Gather Buddy Statements and Military Service Records

VA appeals benefit from lay statements (buddy statements) from fellow service members who witnessed the in-service event or conditions. Obtain your complete service records through a Records Request to the National Personnel Records Center (NPRC). If in-service medical records are unavailable, the lay statements and secondary evidence of an in-service event become even more important.

Step 4: File a TRICARE Appeal Addressing the TRICARE Policy Manual

For TRICARE denials, the appeal must address the specific TRICARE policy provision cited in the denial. Reference the TRICARE Policy Manual (TPM) online at tricare.mil. If the denial involves a medical necessity determination, obtain a letter from the treating physician citing TRICARE's own clinical criteria and demonstrating that the denied service meets those criteria. Peer-to-peer review with the TRICARE Medical Officer is available for TRICARE prior authorization denials.

Step 5: Request VA Community Care Authorization Under the MISSION Act

For VA community care denials, invoke the MISSION Act standards (38 USC §1703): if the VA cannot provide the needed service within 20 days (primary care) or 28 days (specialty care), or within 30 miles of the veteran's residence for certain services, community care must be authorized. File a formal complaint with the VA Patient Advocate at your VA medical center and document the wait time or drive time standard that has not been met.

Step 6: Escalate to the Board of Veterans' Appeals or TRICARE Independent Review

For complex VA claims that are not resolved through Higher-Level Review, the Board of Veterans' Appeals (BVA) provides formal adjudication, including hearings before a Veterans Law Judge. The BVA can order a Veterans Benefits Administration (VBA) examination, obtain additional medical evidence, and issue binding decisions. For TRICARE, an IROs) Explained" class="auto-link">Independent Review Organization (IRO) process is available for medical necessity disputes, administered through the TRICARE contractor.

What to Include in Your Veterans' Insurance Appeal

• Nexus letter from a licensed physician with explicit language stating the required "at least as likely as not" causal standard under 38 CFR §3.102, with specific reference to the in-service event or toxic exposure
• Complete service records and military occupational specialty documentation establishing the nature of service and exposure history
• Current diagnostic records establishing the diagnosis, severity, and functional impact of the condition being claimed
• PACT Act eligibility documentation if the claim involves toxic exposure — deployment location, dates of service, and evidence of burn pit or Agent Orange exposure
• For TRICARE appeals: written denial letter from the TRICARE contractor, treating physician letter citing TRICARE Policy Manual clinical criteria, and any prior authorization correspondence

Fight Back With ClaimBack

Veterans' insurance denials — whether from the VA, TRICARE, or CHAMPVA — require appeals that speak the specific language of each program's clinical criteria and legal standards. A nexus letter that uses the right legal standard, a TRICARE appeal that cites the TRICARE Policy Manual, and a MISSION Act community care request that documents wait time standards are all more effective than generic appeals. ClaimBack generates a professional appeal letter in 3 minutes.
