TRICARE is the healthcare program of the United States Department of Defense Military Health System, providing health coverage to active-duty service members, retirees, their families, and survivors. TRICARE serves approximately 9.6 million beneficiaries worldwide and is one of the most comprehensive health insurance programs in the country.
TRICARE offers several plan options that vary by beneficiary category and preference. Active-duty service members receive TRICARE Prime at no cost, while retirees and family members can choose between TRICARE Prime (managed care), TRICARE Select (PPO-style), and TRICARE For Life (Medicare supplement for retirees 65+). Reservists and National Guard members have access to TRICARE Reserve Select and TRICARE Retired Reserve.
Care is delivered through military treatment facilities (MTFs) such as military hospitals and clinics, as well as a large civilian provider network managed by regional contractors. TRICARE covers beneficiaries both within the United States and overseas, making it unique among health insurance programs in its global reach.
