Answer: Helping intubate a patient is usually a courtesy to the other practitioner and not generally billed separately. If, however, the anesthesiologist spent a substantial amount of time on the intubation -- and thoroughly documented his work -- some carriers might reimburse for the time spent helping or a reduced service.
If you have enough documentation to support the claim, report 31500 (Intubation, endotracheal, emergency procedure). Append modifier 52 (Reduced services) because this was not an emergency.
