milConnect: TRICARE Eligibility & Enrollment Portal Guide

## Definition milConnect is a secure Department of Defense (DoD) web portal that allows TRICARE beneficiaries to manage their enrollment, update personal contact information, and verify healthcare eligibility.

## What it means in practice For a TRICARE beneficiary, milConnect acts as the "master dashboard" for their relationship with the military health system. While your regional contractor (Humana Military or TriWest) handles claims and referrals, milConnect is where you go to make major administrative changes. If you move, get married, or have a child, you must update the Defense Enrollment Eligibility Reporting System (DEERS) via milConnect to ensure your coverage remains active. Failure to keep this information current can result in denied claims or being moved to the wrong TRICARE region.

Beyond DEERS updates, milConnect is the platform used to perform TRICARE Open Season changes. During the annual enrollment period (typically mid-November to mid-December), users log into the "Beneficiary Web Enrollment" (BWE) section of milConnect to switch between TRICARE Prime and TRICARE Select. This is also where you can download official proof of coverage (Eligibility Letters) or check your enrollment status to see if you are in Group A or Group B (which determines your 2026 copayment rates).

The portal also provides access to the "milConnect eCorrespondence" center. This is where the DoD sends critical notifications, such as "loss of eligibility" warnings or enrollment confirmation letters. In 2026, navigating this site is a requirement for service members transitioning to retirement, as they must use milConnect to select their new retiree health plan within 90 days of their retirement date to avoid a gap in coverage.
