If the doctors are in the same speciality only one dr can bill per day. So if dr (a) saw the patient first, he gets to bill the intial visit.. If dr (b) saw the patient the next day, he has to bill subsequent visits... There should be only one specialist in any one catagory seeing this patient. Ex: neurology--you can't have two neuros seeing the same patient.
oh and if the patient comes back to the hosptial then the initial visits starts all over.. One initial visit per stay then the rest are subsequent.
sorry forgot about the caps rule.. Will try to remember next time.
