If you have a new baby or have adopted a child, take the necessary steps to give your child access to health care: (1) register your child, newborn or adoptee, in the Defense Enrollment Eligibility Reporting System (DEERS). You need to register in DEERS to get TRICARE. You do not have to wait the 2-6 months it may take for a formal state department birth certificate; (2) enroll your child in Prime by calling your regional contractor or by submitting a Prime enrollment form. If your family is growing with an adopted child, start the process as soon as you have the information to register them in DEERS. For more information, visit the Enroll or Purchase a Plan webpage on the TRICARE website. You can find the nearest DEERS registration site here.
