The American Medical Association (AMA) is a non-profit 501 (c) (6) – a professional association and the largest association of physicians – whose primary purpose is to:
- publish the Journal of the American Medical Association (JAMA) – a peer reviewed medical journal that includes original research, reviews, and editorials of medicine;
- maintain a code of medical ethics,
- create and maintain physician data which is sometimes referred to as master files; and
- update and maintain medical classification codes (referred to as CPT codes) used by the government, medical practices, hospitals, and insurance companies in return for royalty fees.
