Wiki coding E/M when not in your office

[asagastume]

Our physician is located in a hospital and has her own office. She went to a different location in the hospital to see a patient can she still bill an E/M code for her service. Another specialist is also billing for service on the same day.

I'm assuming based on your question, that she rounded on a patient on the floor after leaving her hospital-based office. Yes, she can bill an E&M, as long as medical necessity is met. Multiple specialties (if appropriate) can round on the same patient during the same day. She would report the appropriate E&M code and POS based on the patient's hospital status (inpatient or observation). The attending provider identifies this based on the -AI modifier. If she's a specialist who is consulting, she'd report the initial hospital code for her first visit, then the subsequent codes for additional days.
I spoke of 'medical necessity'. If she's not the attending of record, and not a specialist asked to consult and is only seeing one of her patients because they are admitted and she simply wants to check in on them, that would not meet medical necessity and you would not bill.
