TRICARE Prior Authorization Denied: How to Appeal" class="auto-link">Prior Authorization Denied: How to Appeal
TRICARE provides healthcare coverage to active duty service members, retirees, and their dependents. Many TRICARE plans require prior authorization (PA) for certain procedures, specialist visits, or services. When a PA request is denied, it can delay or prevent access to needed care. This guide explains why TRICARE PA denials happen and how to navigate the appeal process.
TRICARE Plans and Prior Authorization Requirements
TRICARE offers several plans with different PA requirements:
TRICARE Prime: An HMO-type plan where most care is coordinated through a primary care manager (PCM). Many services require referrals from the PCM and prior authorization from the regional contractor. This plan has the most PA requirements.
TRICARE Select: A PPO-type plan with more flexibility. PA is required for fewer services, but certain high-cost procedures (surgery, inpatient care, specialty drugs, mental health residential treatment) typically require authorization.
TRICARE for Life (TFL): For Medicare-eligible retirees. TRICARE acts as a secondary payer after Medicare. PA requirements are minimal since Medicare's rules govern most coverage decisions.
TRICARE Reserve Select and Retired Reserve: Similar to TRICARE Select; PA required for specific services.
Services that commonly require TRICARE prior authorization include:
- Inpatient hospital admissions (non-emergency)
- Outpatient surgery at non-network facilities
- Certain specialty care beyond a PCM referral
- Mental health inpatient and residential treatment
- Substance use disorder treatment
- Home health care
- Skilled nursing facility care
- Durable medical equipment above a cost threshold
- High-cost specialty pharmaceuticals
- Some imaging (MRI, CT) outside network facilities
Why TRICARE PA Requests Are Denied
- Medical necessity not established: The contractor determines the service does not meet the Defense Health Agency's (DHA) medical necessity criteria
- Service is a TRICARE exclusion: TRICARE specifically excludes certain services (cosmetic surgery, some fertility treatments, experimental procedures)
- Wrong plan type or authorization route: The authorization was requested in the wrong way or the plan requires a different pathway
- Incomplete documentation: The request lacked required clinical documentation
- Network provider available: TRICARE Prime requires use of network providers except in emergencies; a non-network authorization may be denied if a network alternative is available
- Step therapy: TRICARE requires trying less costly alternatives first
How to Appeal a TRICARE Prior Authorization Denial
TRICARE's appeals process has two main levels:
Level 1: Reconsideration (Internal Appeal)
File a formal reconsideration request with your TRICARE regional contractor (Humana Military in the East, or Health Net Federal Services in the West; TRICARE Overseas is handled by International SOS):
Timeframe to file: Within 90 days of the denial notice.

- Written request for reconsideration identifying the denied service and the basis for your appeal
- Letter of medical necessity from the referring physician, clearly explaining the clinical basis for the request, what alternatives have been considered and why they are inappropriate, and relevant clinical guidelines or evidence
- Supporting medical records
- Reference to specific TRICARE/DHA clinical coverage policy criteria if the denial misapplied them
Standard decision timeline: 30 days for non-urgent requests. For urgently needed care, request expedited review and explicitly state that a delay would cause harm — expedited decisions must be issued within 72 hours.
Level 2: Formal Hearing (Independent Review)
If the contractor upholds the denial after reconsideration, you may request a formal hearing before an Independent Hearing Officer (IHO), an official with the Defense Health Agency.
- File within 90 days of the reconsideration denial
- Hearings can be conducted in person or by telephone
- You may present new evidence, call witnesses, and have legal or other representation
- The IHO issues a written decision
Level 3: DHA Appeal Board (for Benefit Denials)
If the IHO upholds the denial, you may appeal to the Defense Health Agency (DHA) appeal board, which is the highest administrative level of TRICARE appeals.
After exhausting all TRICARE administrative levels, you can seek review in federal court.
Key References for TRICARE PA Appeals
TRICARE's clinical coverage policies are published by the Defense Health Agency and are available at health.mil/Military-Health-Topics/Access-Cost-Quality-and-Safety/Health-Care-Program-Evaluation/Clinical-Quality/Clinical-Coverage-Policies. These are the standards contractors must apply when evaluating PA requests. If the contractor denied your PA using criteria inconsistent with the published clinical coverage policy, that is a strong ground for appeal.
Special Situations
Active Duty Service Members: Active duty service members (not dependents or retirees) receive care primarily through military treatment facilities (MTFs). When MTF care is unavailable and they are referred to civilian providers through TRICARE Prime, PA requirements still apply — but the MTF's referral carries significant weight in any appeal.
Mental Health and Substance Use Disorder: TRICARE is required to cover mental health and SUD services in compliance with the Mental Health Parity and Addiction Equity Act (MHPAEA). If your mental health PA was denied using criteria more restrictive than medical/surgical criteria, cite MHPAEA in your appeal.
Children with Special Health Care Needs: The Extended Care Health Option (ECHO) provides supplemental benefits for eligible dependents with qualifying conditions. ECHO has its own authorization process and appeals pathway.
