How to Check TRICARE Eligibility | 2026 Guide | TRICARE.com

## Quick answer To check your TRICARE eligibility, you must log into the **Defense Enrollment Eligibility Reporting System (DEERS)** via the milConnect website. While TRICARE manages health benefits, the Department of Defense (DoD) determines your eligibility based on your status in DEERS.

Details

Checking eligibility is not done through TRICARE directly, but through the DEERS database. If your information in DEERS is incorrect or outdated, you may be denied care or pharmacy benefits.

### 1. The Primary Method: milConnect The most reliable way to verify your status is online through the **milConnect** portal, managed by the Defense Manpower Data Center (DMDC). * **Action:** Visit [milConnect](https://milconnect.dmdc.osd.mil/). * **Login:** You will need a Common Access Card (CAC), DFAS (myPay) credentials, or a DS Logon. * **Menu:** Navigate to "Benefits" and then "Status" to see which TRICARE plans you are currently eligible for.

### 2. Checking by Phone or In-Person If you cannot access the portal, you can verify eligibility through the following channels: * **Phone:** Call the DMDC/DEERS Support Office at 1-800-538-9552. * **ID Card Office:** Visit a local Real-time Automated Personnel Identification System (RAPIDS) site. You can find locations using the [ID Card Office Online](https://idco.dmdc.osd.mil/idco/) locator.

### 3. Plan-Specific Eligibility (2026 Status) Eligibility is determined by your "sponsor" status. Common categories include: * **Active Duty & Families:** Automatically eligible for TRICARE Prime or Select. * **National Guard/Reserve:** Eligibility depends on your military status (Drilling, Active Duty orders, or Retired). You may need to purchase **TRICARE Reserve Select (TRS)**. * **Retirees:** Must be entitled to retired pay to maintain eligibility. At age 65, you must have Medicare Part A and B to remain eligible for **TRICARE For Life (TFL)**.

### 4. Special Considerations for 2026 * **The T-5 Transition:** As of 2025/2026, the West Region is managed by **TriWest Healthcare Alliance**. While your regional contractor manages your *claims*, they still pull your *eligibility* data from DEERS. If you move between the East (Humana Military) and West (TriWest) regions, you must update your address in DEERS immediately to ensure your eligibility reflects the correct regional plan. * **Qualifying Life Events (QLEs):** Outside of Open Season, you can only change your TRICARE plan if you have a QLE (marriage, birth, move, retirement). These must be updated in DEERS within 90 days.

## Who this affects * **Active Duty Service Members (ADSMs)** and their family members. * **Retirees** and their families (including those utilizing TRICARE For Life). * **National Guard and Reserve** members (Active Guard Reserve, Drilling, or Retired). * **Survivors** or former spouses who have not remarried. * **Medal of Honor recipients** and their families.
