Military health clinics and other authorized organizations access the DEERS (Defense Eligibility Enrollment System) database to verify benefit eligibility of military sponsors, family members and other beneficiaries. They also use addresses entered in DEERS to mail information and educational material to beneficiaries. The TRICARE Management Activity has selected International SOS, Inc., as the TRICARE Overseas Program contractor effective September 1. Information and educational material will be mailed soon to beneficiaries to explain how the new overseas managed care contract will benefit them.
