How do I bill a bilateral MRI for United Healthcare, when each procedure is done two days apart i.e."04/22/2013 (LEFT) and 04/24/2013 (RT)"? when procedures are done on the same day, the carrier states to put the item on one line with modifier 50, and put the total charge for two procedures listed as one unit. It doesn't specify how it is to be used on different days though.
thanks
