TRICARE Young Adult: 2026 Guide to Coverage & Costs
*Disclaimer: TRICARE.com is an independent reference site and is not the official TRICARE program. For official policy and the most current government updates, visit TRICARE.mil.*
## Quick answer TRICARE Young Adult (TYA) is a premium-based health plan for adult children (ages 21 to 26) who have "aged out" of regular TRICARE coverage and do not have access to employer-sponsored health insurance. It functions as an extension of the military's healthcare benefits, offering either Prime or Select coverage levels in exchange for a monthly premium.
In detail
When a military dependent turns 21 (or 23 if enrolled in full-time college), they typically lose eligibility for standard TRICARE coverage. TRICARE Young Adult was created to fill the gap until these adult children turn 26.
### Plan Options: Prime vs. Select You cannot "mix and match" these plans; your eligibility for them depends on where you live and your sponsor's status.
* **TYA Prime:** Operates similarly to TRICARE Prime. You have a Primary Care Manager (PCM) and need referrals for specialty care. This is generally available in "Prime Service Areas" in the U.S. and for certain beneficiaries overseas. * **TYA Select:** Operates like TRICARE Select. You have more flexibility to choose your own doctors and do not need referrals, but you pay higher out-of-pocket costs (deductibles and cost-shares) when you receive care.
### 2026 Costs and Premiums Because TYA is not subsidized by the government in the same way active-duty care is, the premiums reflect the actual cost of the insurance.
* **TYA Prime Monthly Premium (2026):** Varies by plan year — check TRICARE.mil for current rates. * **TYA Select Monthly Premium (2026):** Varies by plan year — check TRICARE.mil for current rates.
In addition to monthly premiums, beneficiaries are responsible for: 1. **Enrollment Fees:** None (the monthly premium replaces this). 2. **Deductibles:** Based on the sponsor’s status (Group A or Group B). 3. **Cost-Shares/Copays:** These apply once the deductible is met.
### The 2025 Contractor Shift As of January 1, 2025, the **TriWest Healthcare Alliance** became the sole contractor for the **West Region** under the T-5 contract. If you live in the West, your TYA claims and authorizations are handled by TriWest. In the **East Region**, **Humana Military** remains the contractor.
### Pharmacy Benefits TYA includes full pharmacy coverage managed by **Express Scripts**. You can fill prescriptions at military pharmacies (usually $0), via Home Delivery, or at retail network pharmacies.
## Who this applies to To qualify for TRICARE Young Adult, you must meet all of the following requirements: * **Unmarried:** You must be a single dependent child of an eligible TRICARE sponsor. * **Age:** At least 21 (or 23 if a full-time student) but not yet 26. * **No Employer Coverage:** You must **not** be eligible to enroll in an employer-sponsored health plan under your own employment. * **Not a Sponsor:** You cannot be a member of the selected reserve or on active duty yourself (as you would have your own TRICARE coverage).
Common scenarios
**Scenario 1: The Recent College Grad (TYA Select)** Sarah graduated from college at 23 and moved to a city without a Prime Service Area. She enrolls in TYA Select. In 2026, she pays her monthly premium (e.g., ~$300/mo) and visits an in-network doctor for an injury. She pays her Group B deductible first, then a 20% cost-share for the visit.
**Scenario 2: The Job Seeker (TYA Prime)** Marcus is 22 and living at home while searching for a job. His father is retired Navy living in San Diego (West Region). Marcus enrolls in TYA Prime. Since Jan 1, 2025, his care is managed by TriWest. He pays his monthly premium but has $0 copays for most primary care visits at the local Naval Medical Center.
**Scenario 3: The Waitress (Ineligibility)** Chloe is 24 and works for a large restaurant chain that offers a high-deductible health plan to all employees. Because Chloe is *eligible* for her employer's plan, she is legally disqualified from enrolling in TRICARE Young Adult, even if the employer's plan is more expensive than TYA.
## Related terms * **Sponsor:** The active-duty, retired, or Guard/Reserve member whose service makes the child eligible for TRICARE. * **Premium:** The fixed monthly amount paid to keep the insurance active, regardless of whether care is used. * **Catastrophic Cap:** The maximum out-of-pocket amount a family pays for covered services in a calendar year (Note: TYA premiums do **not** count toward this cap). * **DEERS:** The Defense Enrollment Eligibility Reporting System; the database used to verify TRICARE eligibility. * **Qualifying Life Event (QLE):** A change like turning 21 or graduating college that allows you to enroll in TYA outside of an open enrollment period.
