## Quick answer The milConnect portal is the centralized web gateway managed by the Defense Manpower Data Center (DMDC) that allows TRICARE beneficiaries to manage their healthcare eligibility, enroll in plans, and update personal information. It is the primary tool for accessing the Defense Enrollment Eligibility Reporting System (DEERS) to ensure your military health coverage remains active.

Details

The milConnect portal (milconnect.dmdc.osd.mil) serves as the administrative backbone for TRICARE. While regional contractors (Humana Military or TriWest) handle claims and referrals, milConnect handles the fundamental "who, what, and where" of your benefits.

### Essential Functions for TRICARE Users * **DEERS Updates:** This is the most critical function. If your address, marital status, or contact info is wrong in DEERS (via milConnect), your TRICARE claims may be denied. * **Beneficiary Web Enrollment (BWE):** This tool within milConnect allows you to enroll in or switch plans (e.g., moving from TRICARE Select to TRICARE Prime) during Open Season or following a Qualifying Life Event (QLE). * **Proof of Coverage:** You can generate and print "Wallet Cards" or formal "Proof of Coverage" letters, which are often required when applying for supplemental insurance or proving coverage to outside providers. * **eCorrespondence:** This section contains official notifications regarding your TRICARE eligibility changes or enrollment status.

### Accessing the Portal To log in, you must use one of the following secure methods: 1. **Common Access Card (CAC):** Generally for active duty and GS employees. 2. **DS Logon:** The most common method for retirees and family members. 3. **DFAS myPay credentials:** Use the same login you use to view Leave and Earnings Statements (LES).

### Regional Contractor Integration As of 2026, the TRICARE West Region is managed by **TriWest Healthcare Alliance** and the East Region by **Humana Military**. While you go to milConnect to *enroll* in a plan, you will go to the specific contractor's portal to view claims, find a doctor, or check the status of a referral.

### Important 2026 Deadlines * **Open Season:** Typically runs from the Monday of the second full week in November to the Monday of the second full week in December. Changes made in milConnect during this window take effect January 1, 2027. * **QLE Window:** You generally have 90 days from the date of a life event (marriage, birth, move) to update milConnect/DEERS to maintain or change coverage.

## Who this affects * **Active Duty Service Members:** To manage family enrollment and update contact info. * **National Guard and Reserve:** To check eligibility for TRICARE Reserve Select (TRS). * **Retirees:** To manage TRICARE Select or Prime enrollment and pay premiums. * **Military Families:** To ensure dependents are correctly listed for health and dental benefits. * **Survivors:** To maintain continuity of care and update eligibility status.
