## Bottom line **Lowest cost** is almost always **TRICARE Young Adult (TYA)** because it offers military-subsidized rates that are not income-dependent. **Most flexibility** goes to the **Health Care Marketplace**, which offers hundreds of private plans with varying networks. **Best for families** and **Best for retirees** generally remains **TYA** if the child is between ages 21 and 26 and needs to maintain the same continuity of care they had while active duty dependents.

## Side-by-side comparison The following 2026 rates apply to TYA Prime and Select compared to a standard "Silver" tier Marketplace plan. Marketplace costs vary significantly by state and income-based subsidies (APTC).

| Feature | TYA Prime (2026) | TYA Select (2026) | Marketplace (Silver Plan) | | :--- | :--- | :--- | :--- | | **Eligibility** | Unmarried child of sponsor, age 21–25, not eligible for own employer plan | Unmarried child of sponsor, age 21–25, not eligible for own employer plan | U.S. citizens/nationals; no age limit (usually vs. TYA) | | **Monthly Premium** | ~$650 - $700 (varies by year) | ~$300 - $350 (varies by year) | Varies by income/age ($0 - $600+) | | **Annual Deductible** | $0 | $60 - $300 (Group A/B dependent) | Average $4,500 - $5,500 | | **Primary Care Copay** | $0 (MTF) or ~$25-35 | ~$35 - $45 | ~$30 - $60 | | **Specialist Copay** | ~$40 - $65 | ~$50 - $65 | ~$60 - $100 | | **ER Copay** | ~$100 - $190 | ~$120 - $250 | ~$400 - $700 or % of cost | | **Pharmacy (30-day)** | $16 (Brand) / $68 (Non-prev) | $16 (Brand) / $68 (Non-prev) | Varies; often high deductible applies | | **Referrals Required** | Yes (from PCM) | No | Sometimes (if HMO) | | **Network** | MTF + Humana/TriWest | Any TRICARE-authorized | Plan-specific (PPO/HMO/EPO) | | **Catastrophic Cap** | $4,399+ (Varies by Sponsor) | $4,399+ (Varies by Sponsor) | Up to $9,200 (Individual) |

*Note: 2026 TYA premiums are set annually by the Defense Health Agency and typically increase each January 1st.*

## When to choose each **Choose TRICARE Young Adult** if you are a healthy adult under age 26 who wants to keep your existing military doctors or live near a military treatment facility (MTF). It is the superior choice for those who anticipate needing surgery or high-cost specialty care, as the "catastrophic cap" (the maximum you pay out of pocket) is significantly lower than most private Marketplace plans. TYA is also better if your parents are still active duty or retired and you want to remain within the same administrative system.

**Choose a Marketplace Plan** if your household income is low enough to qualify for substantial Advanced Premium Tax Credits (APTC). If you qualify for a "Silver" plan with cost-sharing reductions, your monthly premium could be near $0, which is significantly cheaper than the TYA Select premium. The Marketplace is also the only option once you turn 26 or if you get married, as both events disqualify you from TRICARE Young Adult.

## Switching between them You can switch from Marketplace to TYA (or vice-versa) during the annual **Open Season** (typically mid-November to mid-December). However, you can switch at any time if you experience a **Qualifying Life Event (QLE)**. Common QLEs include: * Losing "minimum essential coverage" (e.g., turning 21 and losing regular TRICARE). * Moving to a new zip code. * Marriage or having a baby (this would move you off TYA and onto the Marketplace). * Gaining or losing a job that offers health insurance.

If you are aging out of regular TRICARE, you have 90 days from your 21st birthday (or 23rd if a full-time student) to enroll in TRICARE Young Adult to avoid a gap in coverage.
