Is it safe to say, AI modifier should only be applied when there is multiple providers using CPT 99221-23 on same day or it doesn't matter if different days?
first day = consulting provider = admits pt = 99222
second day = hospitalist = going to over see pts care = 99222
this is different days, no other providers saw the pt one first day or second day, should the hospitalist still append AI modifier? or no, because no other provider billed a 99222 on that day? or yes, still apply it because it will tell medicare who will be overseeing the pt.
