The primary mission of Navy Medical Department facilities is to provide medical and dental care for members of the Navy and Marine Corps and for members of the other uniformed services who may be sick, injured, or disabled. In addition, Navy Medical Department facilities may provide medical and dental care to dependents of military personnel, to members not on active duty, and to such other persons as authorized by law, U.S. Navy regulations, and Department of Defense directives. These authorizations also provide that Navy Medical Department facilities may be called upon to furnish medical and dental care, under laws of humanity or principles of international courtesy, to civilians and to other persons not otherwise entitled to medical and dental care.
