Surgical body contouring is surgery and therefore a medical treatment Like all medical treatments, prior to your initial treatment the medical spa should conduct an in-person exam by either a doctor, a nurse practitioner or a physician assistant. Surgical body contouring is most typically performed by an MD, DO, PA or NP; however, AmSpa believes that only an MD or a DO should be performing this procedure. Please check with your local medical board, nursing board or health care attorney for more information.
