Doctor of Osteopathic Medicine (DO or D.O., or in Australia DO USA) is a medical degree conferred by the 38 osteopathic medical schools in the United States. DO and Doctor of Medicine (MD) degrees are equivalent: a DO graduate may become licensed as a physician or surgeon and thus have full medical and surgical practicing rights in all 50 US states. As of 2023, there were 186,871 osteopathic physicians and medical students in DO programs across the United States. Osteopathic medicine (as defined and regulated in the United States) emerged historically from the quasi-medical practice of osteopathy, but has become a distinct and proper medical profession.
