## Quick answer Prior authorization is a requirement where your doctor must get approval from your TRICARE regional contractor (Humana Military or TriWest) before you receive certain medical services or medications. Without this approval, TRICARE may not pay for the care, leaving you responsible for the full cost or a significant penalty fee.

## Details Prior authorization (PA) focuses on medical necessity and ensuring you receive the appropriate level of care. It is distinct from a "referral," which is simply a request for you to see a specialist.

### When Prior Authorization is Generally Required While specific requirements vary by plan, TRICARE usually requires prior authorization for the following: * **Applied Behavior Analysis (ABA):** All services under the Autism Care Demonstration. * **Inpatient Admissions:** Most non-emergency hospital stays, including mental health and substance use disorder treatment. * **Home Health Care:** Specific nursing or therapy services provided at home. * **Durable Medical Equipment (DME):** High-cost items like power wheelchairs or specific prosthetics. * **Transplants:** All organ and bone marrow transplants. * **Specialty Medications:** Many high-cost drugs managed through Express Scripts.

### Regional nuances and the T-5 Contract As of 2026, the management of these authorizations depends on your region: * **East Region:** Managed by **Humana Military**. * **West Region:** Managed by **TriWest Healthcare Alliance**. TriWest took over the T-5 contract (replacing HNFS) and utilizes an updated portal for authorization tracking.

### Penalties for Missing Authorization If you are enrolled in **TRICARE Select** and receive a service that required prior authorization without getting it, you may face a **$300 penalty** per occurrence (2026 rate). This is in addition to your standard deductible and cost-shares. If the service is later deemed "not medically necessary," TRICARE will pay $0.

### Pharmacy Prior Authorizations For prescriptions, **Express Scripts** manages the PA process. If your doctor prescribes a non-formulary drug or a high-cost specialty medication (like certain weight-loss drugs or biologics), the pharmacist will notify you that a PA is required. Your doctor must then submit clinical documentation proving that cheaper alternatives have failed or are contraindicated.

### Active Duty Special Rules Active Duty Service Members (ADSMs) have the strictest requirements. Almost all care received from a civilian provider requires both a referral and prior authorization to ensure "fitness for duty" standards are met.

## Who this affects * **Active Duty Service Members (ADSMs):** Required for nearly all civilian care. * **Active Duty Family Members (ADFMs):** Required for specific high-cost services and most specialty care (if using TRICARE Prime). * **Retirees and their Families:** Required for specialty drugs, inpatient stays, and certain DME. * **TRICARE Reserve Select (TRS) & TRICARE Retired Reserve (TRR) Users:** Subject to the same $300 penalty as TRICARE Select if PA is missed.
