The regional contractors administer TRICARE Prime in each region. We will refer regularly to your regional contractor throughout this handbook, and describe differences in each region. In cases where there are differences, refer to the information specific to your region. We encourage you to visit your regional contractor’s Web site, which includes information about how to change PCMs, how to enroll a newborn or adopted child, covered and non-covered services, referral and authorization requirements, and other helpful information. You can also call your regional contractor toll-free for assistance at the numbers listed below. Regional contractors also have TRICARE Service Centers (TSCs) located throughout the region, typically at MTFs, that have customer service representative to assist you.
