Can a physician assistant inject or prescribe in Michigan?

Short answer
Yes — but only under a written practice agreement with a participating physician, which cannot assign any act outside the PA's license scope; the board may restrict high-risk services and rules may bar certain drug classes from PA prescribing.

Michigan makes the written agreement the precondition, not the paragraph afterwards. “a physician’s assistant shall not engage in the practice as a physician’s assistant except under the terms of a practice agreement that meets the requirements of this section.” It must set out a process for communication, availability and decision making; an alternative physician for consultation when the participating physician is not available; both signatures; a 30-day written termination provision; the duties and responsibilities of each; and a requirement that the participating physician verify the physician assistant’s credentials. It may not assign what either of them cannot DO: the agreement “shall not include as a duty or responsibility of the physician’s assistant or participating physician an act, task, or function that the physician’s assistant or participating physician is not qualified to perform by education, training, or experience and that is not within the scope of the license held” by them.
