Our practice just performed their first fenestrated EVAR. They used a fenestrated aortic cuff with a bifurcated stent graft. They also stented both renal arteries with iCAST stents and used an extension on the right iliac and used an iCAST stent on the left iliac. From what I have researched, I believe the codes would be 0078T, 0079T, 0080T, 0081T for the fenestrated cuff with bifurcated EVAR graft, and codes and 34825, 75953-26 for the extension on the right iliac. Are the renal stents included in the fenestrated graft codes, or can they be coded additionally? And can the iCAST stent for the left iliac be coded with 37221? A stent was done because 'there was only 4-5 mm of available iliac artery to extend the graft and there was noted to be poor apposition of the stent wall due to tortuosity of the proximal iliac artery'.
