TRICARE Sign In Guide: milConnect, TriWest, & Humana

*This site is an independent reference and is not affiliated with the Department of Defense or TRICARE.mil. Use TRICARE.mil for official policy and medical records.*

## Quick answer To sign in to your TRICARE-related accounts, you must use the **milConnect** portal for enrollment, or your specific regional contractor’s website (**Humana Military** in the East or **TriWest** in the West) to view claims and referrals. Most logins require a **DS Logon**, a Common Access Card (CAC), or a DFAS myPay credential.

In detail

Because TRICARE is managed by different entities depending on your region and the type of information you need, there is no single "Sign In" button that does everything. You generally need to access three distinct portals:

### 1. milConnect (The Master Portal) This is managed by the DMDC (Defense Manpower Data Center). This is where you go to update your DEERS information, change your TRICARE plan, or enroll a new dependent. * **Website:** [milconnect.dmdc.osd.mil](https://milconnect.dmdc.osd.mil) * **Authentication:** DS Logon (Levels 1 or 2), CAC, or myPay credentials.

### 2. Regional Contractors (Claims & Referrals) Depending on where you live, you will sign in to a private contractor's portal to see your Explanation of Benefits (EOB), track a referral, or pay monthly premiums (for 2026 plans like TRICARE Reserve Select). * **TRICARE East (Humana Military):** Covers the Eastern US. * **TRICARE West (TriWest Healthcare Alliance):** Covers the Western US. *Note: TriWest assumed management of the West Region as of January 1, 2025.* * **TRICARE Overseas (International SOS):** For beneficiaries living outside the US.

### 3. Pharmacy (Express Scripts) To manage home delivery prescriptions, check co-pays (which for 2026 vary by drug type and pharmacy), or view your medication history, you must sign in to the Express Scripts portal. * **Website:** [militaryrx.express-scripts.com](https://militaryrx.express-scripts.com)

## Who this applies to * **Active Duty Service Members:** Use CAC login for milConnect and MHS GENESIS (medical records). * **Active Duty Family Members:** Primarily use DS Logon to track referrals on Humana Military or TriWest portals. * **National Guard & Reservists:** Must sign in to milConnect to verify eligibility for TRICARE Reserve Select (TRS). * **Retirees:** Use DS Logon or myPay to manage TRICARE Select or Prime enrollment and pay 2026 enrollment fees.

Common scenarios

### Scenario A: Checking a Referral John is a TRICARE Prime enrollee in California (West Region). He was seen by his PCM and needs to see a specialist. He signs in to the **TriWest Healthcare Alliance** patient portal using his DS Logon. He can see if the referral is "Approved" and find the authorization number for the specialist.

### Scenario B: Updating an Address Sarah, an Active Duty spouse, just moved from Virginia to Texas. Because this is a move between the East and West regions, she signs in to **milConnect**. She updates her address in DEERS first, then uses the Beneficiary Web Enrollment (BWE) link within the portal to transfer her enrollment to the West Region for the 2026 plan year.

### Scenario C: Checking RX Status Mark needs to refill a maintenance medication. He signs in to the **Express Scripts** portal. He checks his 2026 co-pay (for example, $16 for a 90-day supply of a generic formulary drug via home delivery) and confirms the shipping status.
