Defense Health Agency

"On October 1, 2013, the Department of Defense established the Defense Health Agency (DHA) to manage the activities of the Military Health System. These activities include those previously managed by TRICARE Management Activity (TMA), which was disestablished on the same date. During the next several months, all TMA websites will change to reflect the new DHA. We appreciate your patience during this transition."
