Ilio-mesenteric bypass using a harvested vein
Date: Nov 4, 2022
Question:
How do you code an arterial bypass involving the anastomosis of the iliac artery and mesenteric artery? Code 35633 is for other than a vein; however, in our case a vein was used. Procedure described as being performed was "right common iliac artery to superior mesenteric artery bypass graft with a segment of the femoral vein harvested from the right lower extremity". Patient had a postoperative diagnosis of mesenteric arterial ischemia with occluded superior mesenteric artery bypass graft. Should this be an unlisted code?
