TRICARE Login Guide: Access milConnect, TriWest & East Portals

*TRICARE.com is an independent reference site and is not affiliated with the Department of Defense or the official TRICARE program. For official policy and secure portal access, visit TRICARE.mil.*

## Quick answer There is no single "TRICARE login" for everything. Depending on what you need to do, you will use one of three main portals: the **milConnect / DS Logon** portal for eligibility and enrollment, your **Regional Contractor's portal** (Humana Military or TriWest) for claims and referrals, or **Express Scripts** for pharmacy management. Most users should start by securing a Level 2 (Premium) DS Logon.

In detail

Managing your TRICARE benefits electronically requires navigating different secure systems. As of 2026, the military health system relies on the **T-5 contract** framework, which determines which contractor portal you use based on your geographic location.

### 1. The Gateway: DS Logon (milConnect) The **Defense Self-Service Logon (DS Logon)** is your primary "master key." This is maintained by the Defense Manpower Data Center (DMDC). * **What you do here:** Update personal information, change your TRICARE plan (during Open Season or a QLE), and view your digital ID card. * **Access level:** You need a **Premium (Level 2) account** to view personal health data. You can obtain this via a CAC card, a remote identity proofing process, or by visiting a RAPIDS office.

### 2. Regional Contractor Portals (Claims & Referrals) Once you are enrolled, you will use your specific regional portal for day-to-day medical management. * **East Region (Humana Military):** Use this if you live in the eastern half of the U.S. You login here to check the status of a referral, view Explanation of Benefits (EOB) statements, and pay TRICARE Select or TRS premiums. * **West Region (TriWest Healthcare Alliance):** Effective January 1, 2025, TriWest took over the West region. You must create an account on the TriWest portal to manage claims and authorizations if you reside in the western U.S. * **Overseas (International SOS):** For members stationed outside the U.S., the TOP (TRICARE Overseas Program) portal handles claims and assistance.

### 3. Pharmacy & Vision Portals * **Express Scripts:** This is the universal login for TRICARE Pharmacy benefits. Here you order home delivery, check prescription prices, and manage refills. * **BENEFEDS:** Used specifically for the Federal Employees Dental and Vision Insurance Program (FEDVIP). If you are a retiree seeking vision coverage in 2026, you login here to enroll.

## Who this applies to * **Active Duty Service Members (ADSMs):** Primarily use MHS GENESIS for records and milConnect for DEERS updates. * **Active Duty Family Members (ADFMs):** Use regional portals (Humana/TriWest) to track authorizations for specialty care. * **Retirees & Survivors:** Must use regional portals to manage monthly premium payments (e.g., TRICARE Select enrollment fees, which in 2026 vary by Group — check TRICARE.mil for current rates). * **National Guard & Reserve:** Use milConnect to purchase TRICARE Reserve Select (TRS) and regional portals to manage payments.

Common scenarios

### Scenario 1: Checking a Referral A TRICARE Prime enrollee in California (West Region) is referred to a dermatologist. They login to the **TriWest Healthcare Alliance** patient portal using their DS Logon to see if the authorization has been approved before the specialist calls to schedule. There is no cost to view this status.

### Scenario 2: Updating a Mailing Address A family moves from Fort Liberty, NC to Fort Bliss, TX. The sponsor logs into **milConnect** first to update their address in DEERS. This ensures the 2026 enrollment records stay active. Because they moved from the East Region to the West Region, they then login to the TriWest portal to select a new Primary Care Manager (PCM).

### Scenario 3: Checking Pharmacy Costs A retiree is prescribed a Tier 3 (non-formulary) medication. They login to the **Express Scripts** portal. In 2026, they can use the "Price a Medication" tool to see if the copay is $68 (Home Delivery) or higher at a retail pharmacy, allowing them to choose the most cost-effective login-based option.

## Related terms * **DEERS:** The Defense Enrollment Eligibility Reporting System; the database that proves you are eligible for TRICARE. * **DS Logon:** A secure identity credential used to access multiple DoD and VA websites. * **MHS GENESIS:** The electronic health record system used at military hospitals and clinics for messaging doctors and viewing lab results. * **Explanation of Benefits (EOB):** A document found on contractor portals detailing what TRICARE paid and what the patient owes. * **Open Season:** The annual period (typically Nov-Dec) when you can login to milConnect to change your TRICARE plan for the following year.
