What is NAICS 621112

NAICS code 621112 covers establishments primarily engaged in the independent practice of psychiatry and psychoanalysis by health practitioners holding M.D. (Doctor of Medicine) or D.O. (Doctor of Osteopathic Medicine) degrees. These practitioners provide specialized mental health services, typically operating private or group practices in their own offices, clinics, or as part of hospital and health maintenance organization (HMO) facilities.
