Common scenarios

### Scenario 1: Specialist Referral in San Diego An Active Duty spouse in San Diego is enrolled in TRICARE Prime. Her PCM at the Naval Medical Center San Diego refers her to a civilian neurologist. TRIWOPS (via TriWest) processes the authorization. Because she is Active Duty Family, her copay for the specialist visit is **$0**, provided the authorization is on file.

### Scenario 2: Retiree Urgent Care in Denver A retiree in Denver enrolled in TRICARE Select (Group A) visits an in-network urgent care center. Under 2026 rates, they do not need a referral. TRIWOPS processes the claim, and the retiree pays a flat **$37 copay** at the time of the visit.

### Scenario 3: TRS Member in Seattle A member of the Washington National Guard is enrolled in TRICARE Reserve Select. They visit an in-network primary care doctor for a check-up. TRIWOPS processes the claim against their 2026 deductible. Once the deductible is met, the member pays a **20% cost-share** of the TRICARE-allowable amount.
