The MC traces its earliest origins to the first physicians recruited by the Medical Department of the Army, created by the Continental Congress in 1775. The US Congress made official the designation "Medical Corps" in 1908, although the term had long been in use informally among the Medical Department's regular physicians.

Currently, the MC consists of over 4,400 active duty physicians representing all the specialties and subspecialties of civilian medicine. They may be assigned to fixed military medical facilities, to deployable combat units or to military medical research and development duties. They are considered fully deployable soldiers. The Chief of the Medical Corps Branch (under the Army's Human Resources Command) is a colonel and the senior-most Medical Corps officer in the Army is the U.S. Army Surgeon General, a lieutenant general.
