In researching how many times you can use 61626 for embolization for epistaxis, the word is once per operative field..but not sure what this means. If pt has one procedure done, and 3 different vessels are embolized, the rt and lt internal maxillary, and the lt facial, then can you code 61626 3x with 75894 and 75798 3 times also, for each vessel embolized? (plus all the dx angios, and cath placements), Or since this was a single surgery just code it once ? It was done transcath by way of femoral artery..The info i found is contradictory...Dr. Z mentions using a 59 modifier so that makes me think i can code it for each vessel like you can with angioplasty/atherectomy rules, but then i read that only code it once per operative field....thanks!
