## Quick answer TRICARE covers most uniformed service members, retirees, and their families, providing "medically necessary" and "proven" medical care. This includes preventive screenings, outpatient visits, hospitalizations, and prescriptions, though specific costs and rules for seeing specialists depend on whether you are in a Prime or Select plan.

## In detail To understand TRICARE coverage, you must distinguish between **who** is eligible and **what** services meet the clinical criteria for payment.

### Who is Covered? Eligibility is managed through the Defense Enrollment Eligibility Reporting System (DEERS). Generally, coverage extends to: * **Active Duty Service Members (ADSMs):** Mandatory enrollment in TRICARE Prime; 100% of care is covered. * **Active Duty Family Members (ADFMs):** Eligible for Prime (no out-of-pocket costs) or Select (deductibles and copays apply). * **Retirees and their families:** Eligible for TRICARE Select or TRICARE Prime (requires enrollment fees). * **National Guard/Reserve:** Eligible for TRICARE Reserve Select (TRS) while in a qualified status. * **Survivors & Former Spouses:** Subject to specific "20/20/20" or "20/20/15" rules regarding years of marriage and service.

### What is Covered? TRICARE policy dictates that a treatment must be **medically necessary** and **proven**. This means it must be accepted by the professional medical community as safe and effective.

| Category | Coverage Status | Notes | | :--- | :--- | :--- | | **Preventive Care** | Covered 100% | Includes annual exams, immunizations, and cancer screenings. No copay for any plan. | | **Hospitalization** | Covered | Emergency stays are covered; elective stays require prior authorization. | | **Prescriptions** | Covered | Managed by Express Scripts. Generic formulary drugs are cheapest ($16 for 90-day mail order in 2026). | | **Mental Health** | Covered | Includes outpatient therapy and inpatient residential treatment. | | **Maternity** | Covered | Includes prenatal care, delivery, and postpartum care. | | **Dental** | Limited | Separate enrollment required (TRICARE Dental Program or FEDVIP). | | **Vision** | Limited | ADSMs/Prime get routine eye exams; others vary by plan. |

### Exclusions (What is NOT covered) TRICARE generally excludes: * **Cosmetic Surgery:** Unless required due to accidental injury or congenital anomaly. * **Acupuncture:** Usually not covered (unless part of specific pilot programs). * **Experimental Treatments:** Procedures not yet backed by clinical evidence. * **Custodial Care:** Non-medical care that helps with daily living (bathing, dressing).

## Who this applies to * **Group A Beneficiaries:** Those whose sponsor entered service before Jan. 1, 2018. They generally have lower enrollment fees. * **Group B Beneficiaries:** Those whose sponsor entered service on or after Jan. 1, 2018. They have higher enrollment fees and fixed copays. * **Medicare-Eligible Retirees:** Must enroll in TRICARE For Life (TFL), which acts as secondary coverage to Medicare Part B. * **Young Adult Dependents:** Children aged 21–26 who are not married or eligible for employer-sponsored insurance may buy TRICARE Young Adult (TYA).

Common scenarios

**Scenario 1: Active Duty Spouse (TRICARE Select)** Jane is an Army spouse using TRICARE Select in the East Region (Humana Military). In 2026, she visits an in-network specialist for a sinus infection. Because she has met her deductible, she pays a fixed copay (estimated at $30–$40 for Group B in 2026) instead of the full bill.

**Scenario 2: Retired Officer (TRICARE Prime)** Mark retired in 2020 (Group A). He and his wife pay an annual enrollment fee (approximately $390+ for a family in 2026). Mark needs knee surgery. Because he is on TRICARE Prime, he gets a referral from his Primary Care Manager (PCM), and his surgery costs are $0 out-of-pocket, provided he stays in the network.

**Scenario 3: Pharmacy Pick-up** A beneficiary fills a 30-day supply of a brand-name "preferred" medication at a retail network pharmacy. In 2026, they pay a $43 copay. If they switched to mail-order via Express Scripts, they would pay $38 for a 90-day supply.

## Related terms * **DEERS:** The database used to verify identity and TRICARE eligibility. * **Medically Necessary:** Care that is appropriate, reasonable, and required for the diagnosis or treatment of an illness/injury. * **Prior Authorization:** Approval required from a regional contractor (Humana or TriWest) before specialized care. * **Catastrophic Cap:** The maximum amount a family will pay out-of-pocket for covered services each year. * **Point-of-Service (POS) Option:** An expensive choice for Prime users to see any provider without a referral.
