Ask Dr. Z

Our surgeon attempted to perform a FEVAR on the patient, but, due to graft rotation and multiple attempts to salvage the orientation, it was unsuccessful. Catheters were selectively placed into the renals, and bilateral renal angioplasty was done prior to FEVAR attempt. He then converted to open repair of AAA and assoc. iliac artery occlusive dz with aortobifemoral bypass (18 x 9 bifurcated Dacron graft). Cutdown on both groins over femoral arteries. Explant of proximal body of a Cook Zenith fenestrated graft. Open repair ensued of above stated procedure." Please tell me how you would code this.
