The United States Public Health Service Commissioned Corps (PHSCC), also referred to as the Commissioned Corps of the United States Public Health Service, is the federal uniformed service of the U.S. Public Health Service (PHS), and is one of the eight uniformed services of the United States. The commissioned corps' primary mission is the protection, promotion, and advancement of health and safety of the general public.
Along with the NOAA Commissioned Officer Corps, the Public Health Service Commissioned Corps is one of two uniformed services that consist only of commissioned officers and has no enlisted or warrant officer ranks, although warrant officers have been authorized for use within the service. Officers of the commissioned corps are classified as noncombatants, unless directed to serve as part of the military by the president or detailed to a service branch of the military. Members of the commissioned corps wear uniforms modeled after the United States Navy and the United States Coast Guard, with special PHS Commissioned Corps insignia, and hold naval ranks equivalent to officers of the Navy and Coast Guard. Commissioned corps officers typically receive their commissions through the commissioned corps's direct commissioning program.
As with its parent division, the Public Health Service, the commissioned corps is under the direction of the United States Department of Health and Human Services. The commissioned corps is led by the surgeon general, who holds the rank of vice admiral. The surgeon general reports directly to the Department of Health and Human Services assistant secretary for health. The assistant secretary for health may be appointed to the rank of admiral if he or she is also a serving uniformed officer of the commissioned corps.
