TRICARE Authorizations: What Services Require Approval? (2026)

While routine care from your primary doctor usually doesn't need paperwork, most specialty care, surgeries, and high-tech imaging require "Prior Authorization" or a referral before you receive the service. If you skip this step, TRICARE may deny the claim entirely or apply a "Point-of-Service" deductible that can cost you hundreds of dollars out of pocket.

In detail

In the TRICARE system, "Authorization" is the process where your regional contractor (Humana Military in the East or TriWest in the West) reviews a requested medical service to ensure it is medically necessary and a covered benefit.

### Services that almost always require Authorization Regardless of your plan, the following services typically require prior approval from your regional contractor: * **Applied Behavior Analysis (ABA):** All ABA services for Autism Spectrum Disorder. * **Inpatient Admissions:** Stays for rehabilitation, mental health, or substance use disorders. * **High-Tech Imaging:** MRI, MRA, PET scans, and CT scans (except in emergencies). * **Home Health Care:** Including skilled nursing and physical therapy at home. * **Durable Medical Equipment (DME):** Items like oxygen concentrators or specialized wheelchairs costing over a specific threshold (often $2,000+). * **Transplants:** All organ and bone marrow transplants. * **Hospice Care:** Requires specialized authorization to trigger the hospice benefit. * **Gender Affirming Care:** Specific hormone therapies or surgical consultations (subject to strict DHA policy).

### Referrals vs. Authorizations A **referral** is when your Primary Care Manager (PCM) sends you to a specialist (e.g., a cardiologist). An **authorization** is the contractor's "okay" for a specific procedure (e.g., heart surgery). Often, the specialist handles the authorization request after your first referral visit.

### Plan-Specific Requirements (2026 Rules) * **TRICARE Prime:** You must have a referral for almost all specialty care. If you see a specialist without a referral, it is processed under the **Point-of-Service (POS) Option**, which carries a **$300 individual / $600 family deductible** (2026 rates) followed by a 50% cost share. * **TRICARE Select:** You generally do not need referrals for most office-based specialty care if you use a network provider. However, you **do** still need prior authorization for the high-level services listed above (imaging, inpatient stays, etc.). * **TRICARE For Life (TFL):** Because Medicare is primary, TRICARE acts as a secondary payer. You typically follow Medicare's rules. If Medicare covers it, TRICARE usually pays its portion without a separate authorization.

### The Role of Regional Contractors As of 2026, the contractors responsible for processing these authorizations are: * **East Region:** Humana Military * **West Region:** TriWest Healthcare Alliance (T-5 Contract)

## Who this applies to * **Active Duty Service Members (ADSMs):** Must have a referral/authorization for *all* care outside of a Military Hospital or Clinic. There are no exceptions; skipping this can lead to "fitness for duty" issues. * **Active Duty Family Members (ADFMs):** On Prime, you need referrals for specialists. On Select, you only need prior authorization for major procedures/imaging. * **Retirees and their Families:** Requirements vary by plan (Prime vs. Select), but prior authorization for inpatient stays is universal. * **TRICARE Reserve Select (TRS) / TRICARE Retired Reserve (TRR) Members:** These plans function like TRICARE Select; authorizations are required only for specific "high-cost" or "high-tech" services.

Common scenarios

### Scenario 1: The MRI (TRICARE Select) Jane is on TRICARE Select in the West Region. Her doctor wants an MRI of her knee to check for a meniscus tear. Even though Jane doesn't need a referral to see an orthopedic specialist, the specialist must submit a prior authorization request to **TriWest** before the MRI is scheduled. If Jane gets the MRI without this, she might face a $500+ bill depending on the facility's rates.

### Scenario 2: The Self-Referral (TRICARE Prime) Mark is an Army retiree on TRICARE Prime in the East Region. He has a skin rash and decides to see a dermatologist in town without telling his PCM. Because he didn't get a referral via **Humana Military**, the claim is processed under the Point-of-Service option. Mark must pay the first **$300 (2026 POS deductible)** plus 50% of the remaining bill.

### Scenario 3: Emergency Room Visit Sara (Active Duty) goes to a civilian ER because she thinks she is having a heart attack. This does **not** require prior authorization. Emergency care is always covered first; however, if the ER wants to admit her to a non-military hospital for a three-day stay, the hospital must notify the regional contractor within 24–48 hours for "continued stay" authorization.

## Related terms * **Medical Necessity:** The criteria used by contractors to decide if a service is actually needed to treat a condition. * **Point-of-Service (POS) Option:** A feature of Prime plans allowing patients to see any doctor without a referral, but at a much higher cost. * **PCM (Primary Care Manager):** The "gatekeeper" doctor responsible for issuing referrals in TRICARE Prime. * **Network Provider:** A doctor who has a contract with Humana or TriWest and agrees to handle the authorization paperwork for you. * **Non-Availability Statement (NAS):** An older term mostly replaced by modern authorizations, denoting care cannot be provided at a military facility.
