We have an ARNP in our office who saw a patient for a problem, spent 40 minutes with her. The patient wanted to discuss a procedure, ESSURE, that the mid-level cannot do so the supervising physician, an MD, then saw the patient for an additional 30 minutes (ARNP was no longer in the room) to discuss the procedure. I believe that this encounter should be billed with two office visits, one for each provider, but am being asked to bill it as a 99215 and 99354. I was looking for something to back up how I believe it should be coded, but have been unable to find anything. Am I incorrect? Can this be billed as a prolonged OV?
