Sierra Military Health

Sierra Military Health Services (SMHS) was a specialized healthcare management company that primarily served as a contractor for the TRICARE program, providing managed care support to U.S. military personnel, retirees, and their families. As a subsidiary of Sierra Health Services, the company managed extensive networks of civilian healthcare providers and operated TRICARE Service Centers, particularly in the Northeast United States. In 2008, its parent company was acquired by UnitedHealth Group for approximately $2.6 billion, leading to the integration of its operations into UnitedHealthcare's military and veterans division. SMHS was known for its role in coordinating care between military treatment facilities and private sector providers to ensure comprehensive health benefits for the uniformed services.
