Hello,
I'm looking for written proof (CMS) stating that an Anesthesiologist must remain present in the OR for the duration of a case when billing with modifier AA. Is there any policy that states the definition of Modifier AA, other than "Anesthesia services performed personally by anesthesiologist"? The cases in question involve Monitored Anesthesia Care. The doctor would like to leave the room and have an RN (not a CRNA) monitor the case. I think the answer is no you can't do that but would like written proof from Medicare.
Thanks in advance.
