Hello Everybody, I have a dilemma. We usually bill for a Brain MRI with and without contrast 70553 and for a Brain MRA w/o contrast 70544 on the same day of service. According to Medicare under NCCI edits, I can unbundle these services, however, I am not sure If I can use modifier 59? 25? or 51? I thought I could use modifier "59", however Noridian JE Part B aka (Medicare) does not even have modifier 59 listed! Does anyone knows if it is appropriate to use modifier 59 to unbundle those two services????
