A patient presented to vascular surgery for treatment of shaggy aorta with evidence of atheroembolic sequelae to bilateral feet. The patient underwent endovascular thoracoabdominal aortic repair, with deployment of chimney stent grafts into the celiac, superior mesenteric and bilateral renal arteries. A left common femoral to right common femoral artery bypass graft was performed, with endarterectomies of the femoral arteries, and distal external iliac artery. Are separate codes assigned for placement of the chimney stent grafts?
Yes, separate codes are assigned for placement of the chimney stent grafts, because the insertions of the stent grafts were a distinct surgical objective from the other procedures performed. The chimney stent grafts were placed to maintain and preserve blood flow to the branch arteries and sustain end organ function. The root operation “Insertion” is appropriate for the placement of the chimney stent grafts for this purpose. Assign the following ICD-10-PCS codes:
