Whatever your military status, your registration in the Defense Enrollment Eligibility Reporting System (DEERS) is especially necessary with respect to establishing your TRICARE eligibility. Without your enrollment in DEERS or an enrollment with the correct information, beneficiaries could find their coverage has lapsed, leaving problems with TRICARE claims. Not updating DEERS also hinders your healthcare team's ability to contact you. Updating DEERS is very easy and subsequent updates to the medical information systems happen almost instantaneously. DEERS updates should be made every time you reenlist, transfer, have a change in your dependents' status (marriage, divorce, or new child), move or change your phone number. For changes to information like address, e-mail or phone number, servicemembers can visit the milConnect webpage at www.dmdc.osd.mil/milconnect.
