Seems clear cut to me. (Full disclosure, I’m a radiologist). He is a physician who is practicing medicine. He would be hard pressed to claim that he has no patients as he would soon discover if he had a misdiagnosis leading to a malpractice suit. He may not be subject to inspections (radiologists are typically are not) but he practices under a state license and its stipulations and is held to the standards of the American Board of Radiology assuming that he is board certified. He is practicing medicine in an office, i.e. , a medical office.
