TRICARE is the uniformed services* health care program for active duty service members and their families, retired service members and their dependents,  members of the National Guard and Reserve and their families, survivors, and
others who are eligible. TRICARE’s primary objective is to deliver a world-class health care benefit for all Military Health System (MHS) beneficiaries that ensures the highest level of patient satisfaction.


TRICARE brings together the health care resources of the uniformed services and networks of civilian health care professionals, institutions, pharmacies, and suppliers to provide access to high-quality health care services while maintaining
the capability to support military operations.


TRICARE is available worldwide. In the United States, TRICARE is divided into three separate regions—TRICARE North, TRICARE South, and TRICARE West. The TRICARE Overseas Program is administered as one overseas region
divided into three areas—TRICARE Eurasia- Africa, TRICARE Pacific, and TRICARE Latin America and Canada.


In the United States, TRICARE is managed jointly by the TRICARE Management Activity (TMA) and TRICARE Regional Offices. TMA has contracted with civilian managed care support contractors in the North, South, and West regions
to assist TRICARE regional directors and military treatment facility (MTF) commanders in operating an integrated health care delivery system.
