TRICARE Claim Denied? Military Health Insurance Appeal Guide

TRICARE covers active duty service members, military retirees, and their families across every plan type — Prime, Select, For Life, and Reserve Select. When TRICARE denies a claim or Prior Authorization Denied: How to Appeal" class="auto-link">prior authorization, the appeal process differs from civilian insurance in important ways: it involves contractor-based administration, distinct plan-specific rights, and a uniquely powerful escalation option through congressional liaison. This guide explains every step.

Why Insurers Deny TRICARE Claims

TRICARE claim denials follow recognizable patterns. Understanding which applies to your situation determines your appeal strategy.

Unauthorized referral or network issue (TRICARE Prime). Prime is an HMO-style plan requiring care through a Primary Care Manager (PCM) and referrals for specialty care. Denials frequently occur when a member sought specialty care without a PCM referral, or when the referral was not obtained through the correct authorization pathway.

Out-of-network use at higher cost-sharing (TRICARE Select). Select is a PPO allowing direct access to TRICARE network providers. Claims are denied or reduced when a member uses non-network providers without understanding the increased cost-sharing, or when there is a dispute about whether a provider was in-network at the time of service.

Medicare denial carries over to TRICARE For Life (TFL). TFL pays after Medicare for Medicare-eligible retirees. When Medicare denies a claim, TRICARE follows. Appeals for TFL denials where Medicare is the primary payer must target Medicare first — a TRICARE appeal alone will not resolve the issue.

Not medically necessary. TRICARE applies clinical criteria to determine whether a service is medically necessary. If the treating physician's documentation does not specifically address TRICARE's criteria, the claim is routinely denied on this basis.

Prior authorization not obtained. TRICARE requires prior authorization for specialty care under Prime, most inpatient admissions, certain procedures, and many specialty medications. Failure to obtain authorization before service is one of the most common denial reasons.

How to Appeal a TRICARE Denial

Step 1: File a Request for Reconsideration with Your Regional Contractor

Your first-level appeal goes to the TRICARE regional contractor — Humana Military (TRICARE East, 1-800-444-5445) or HealthNet Federal Services (TRICARE West, 1-844-866-9378). File within 90 days of the denial. Include a copy of the denial notice, your provider's letter of medical necessity with clinical details, supporting medical records, and a clear statement of the basis for your appeal. The contractor must respond in writing; standard processing is approximately 60 days.

Step 2: File a Formal Appeal with the Defense Health Agency (DHA)

If the contractor upholds the denial, file a formal written appeal directly with the Defense Health Agency. This is a higher-level review outside the contractor's authority. File within 90 days of the contractor's final adverse decision. Include all prior correspondence, denial notices, and supporting clinical documentation.

Step 3: Request a Peer-to-Peer Clinical Review

For prior authorization denials, your provider should request a peer-to-peer review with TRICARE's medical director before or alongside the formal appeal. Physician-to-physician clinical review resolves a significant proportion of prior authorization denials that would otherwise require full appeals.

Step 4: Request a Board of Review Hearing

For significant denials, TRICARE maintains a formal Board of Review process providing an independent administrative hearing. Contact the DHA for the specific procedures applicable to your claim type and plan.

Step 5: Contact Your Congressional Liaison

One of the most distinctive and effective escalation tools for TRICARE disputes is a congressional inquiry. Congressional casework carries significant administrative weight with the Defense Health Agency. Contact your U.S. Representative or Senator's office (house.gov and senate.gov), explain the denial and prior appeal attempts, and request a congressional inquiry to the DHA. Congressional liaisons at the DHA are required to respond to congressional inquiries promptly. This option is particularly effective for complex cases, unreasonably delayed appeals, and situations involving urgent medical need.

Step 6: File a Complaint with Your State Insurance Commissioner or CMS

For commercial plan aspects of TRICARE coverage, state insurance departments may have jurisdiction. For Medicare Advantage or coordination of benefits disputes, CMS complaints are available.
