What must the supervising physician actually do in Arizona?
Oversight · part of The Practice Perimeter
Short answer
For injections by a medical assistant, a physician, PA or nurse practitioner must be in the same room or office suite; being reachable by phone isn't enough. Failing to supervise assistants is unprofessional conduct.
A medical assistant may take body fluid specimens and administer injections only under the direct supervision of a doctor of medicine, physician assistant or nurse practitioner. Arizona lists separately the tasks a medical assistant may do WITHOUT direct supervision — billing, coding, insurance, scheduling, charting, visual acuity screening — and injections are not among them.

“Direct supervision” has a physical threshold in Arizona: it means the physician, physician assistant or nurse practitioner is within the same room or office suite as the medical assistant, in order to be available for consultation about the tasks performed under §32-1456. Reachable by phone is not direct supervision.

A medical assistant is an unlicensed person who may perform delegated tasks commensurate with their training but may not diagnose or design/modify a treatment program. Failing to adequately supervise medical assistants or other personnel is itself unprofessional conduct.

It is not legal, medical, or compliance advice, and using it creates no attorney-client relationship. A summary can lag its source or leave out detail, and monitoring itself can be interrupted — so an absence of alerts means nothing reached you, not that nothing happened.
