TRICARE Sign In: Portals & Login Guide 2026

*Note: TRICARE.Com is an independent reference site and is not an official government platform. For official policy and secure personal data, visit TRICARE.mil.*

## Quick answer There is no single "sign-in" for TRICARE; instead, you use different portals depending on what you need to do. To check eligibility or update contact info, you log into **milConnect**; to manage medical claims/referrals, you log into your regional contractor’s site (**Humana Military** for East, **TriWest** for West); and for prescriptions, you use **Express Scripts**.

In detail

Managing your TRICARE benefits requires navigating three primary secure portals. Most of these sites require a **DS Logon**, **Common Access Card (CAC)**, or **DFAS myPay credentials**.

### 1. Personal Info and Eligibility (milConnect) Managed by the Defense Manpower Data Center (DMDC), this is the "master" record for all beneficiaries. This is where you go to: * Update your address, phone number, and email (essential for keeping coverage). * Enroll in a new plan (e.g., switching from TRICARE Select to TRICARE Prime). * View your proof of coverage letter. * Transfer Post-9/11 GI Bill benefits to dependents. * **Sign-in Site:** [milConnect](https://milconnect.dmdc.osd.mil/)

### 2. Medical Claims and Referrals (Regional Contractors) Once enrolled, your day-to-day medical management happens through your specific regional contractor. As of 2026, the contractors are: * **TRICARE East (Humana Military):** Covers 32 states in the eastern U.S. Use this portal to check if a referral was approved, view the status of a claim, or pay monthly premiums for 2026 plans like TRICARE Reserve Select. * **TRICARE West (TriWest Healthcare Alliance):** Covers 21 states in the western U.S. (Since Jan 1, 2025). Use this portal for the same functions as the East portal if you live in the West. * **TRICARE Overseas (International SOS):** For beneficiaries living outside the U.S.

### 3. Pharmacy Benefits (Express Scripts) To manage your medications, see your formulary, or set up home delivery, you must sign in through the Express Scripts TRICARE portal. * **Sign-in Site:** [Express Scripts TRICARE](https://www.express-scripts.com/tricare)

Comparison of Sign-In Portals (2026)

## Who this applies to * **Active Duty Service Members:** Primarily use milConnect for family enrollment and the regional contractor for specialty care referrals. * **Retirees and Families:** Must sign in to regional portals to track 2026 catastrophic caps and deductible spending. * **National Guard & Reserve:** Use milConnect to verify eligibility for TRICARE Reserve Select and to set up initial premium payments. * **Young Adult Dependents:** Use milConnect to enroll in TRICARE Young Adult (TYA) after aging out of standard coverage at 21 (or 23 if a full-time student).

Common scenarios

**Scenario 1: Checking a Specialist Referral** Jane is a TRICARE Prime enrollee in California (West Region). She was referred to a cardiologist. To see if the authorization is ready, she signs into the **TriWest Healthcare Alliance** portal. She sees her 2026 referral is "Approved" and prints the authorization number for her doctor.

**Scenario 2: Moving from Florida to Texas** The Smith family is moving from Florida (East) to Texas (West). They first sign into **milConnect** to update their address. Once the address change is processed, they must sign into the **TriWest** portal to select a new Primary Care Manager (PCM) in their new location.

**Scenario 3: Tracking Out-of-Pocket Costs** Mark, a retiree on TRICARE Select (Group A), has had several surgeries in 2026. He signs into the **Humana Military** portal to check his "Explanation of Benefits" (EOB). He sees he has reached his $4,171 catastrophic cap for 2026, meaning his remaining covered medical costs for the year will be $0.

## Related terms * **DS Logon:** A secure identity credential used to access various DoD and VA websites. * **DEERS:** The Defense Enrollment Eligibility Reporting System; the database that milConnect views and updates. * **EOB (Explanation of Benefits):** An itemized statement showing what TRICARE paid and what the patient owes. * **PCM (Primary Care Manager):** The specific doctor or clinic assigned to coordinate care for Prime enrollees. * **Catastrophic Cap:** The maximum out-of-pocket amount a family pays for covered services in a calendar year.
