The ultimate responsible organization for administration of Tricare is the
U.S. Department of Defense Military Health System, which organized the Tricare Management Activity. The Tricare Management Activity contracts with several large health insurance corporations to provide claims processing, customer service and other administrative functions to the Tricare program.
Basic structure Currently, there are three regional managed-care support contractors, a Medicare/Tricare dual-eligible fiscal intermediary contractor, and a Tricare pharmacy contractor, who administers both mail-order pharmacy and retail pharmacy programs. In addition several administrative contractors provide quality management, auditing, and statistical services.
