Ask Dr. Z

Code 35121 is an open procedure, and code 37236 is for occlusive disease. Would I use an unlisted code?

"It was determined to repair the common hepatic artery aneurysm with placement of covered stent graft, as there was proximal and distal landing zone identified. The guidewire was exchanged to a 0.014 inch run-through wire. Next, a Gore Viabahn stent graft 6 mm x 25 mm was advanced and deployed distally in the common hepatic artery, and this was then expanded with a 5 mm balloon. Next, a Gore Viabahn 7 mm x 25 mm stent graft was advanced and deployed in the proximal common hepatic artery, allowing for adequate overlap, and the stent grafts were then angioplastied with a 6 mm balloon. Completion angiogram revealed excellent positioning of the stent grafts with adequate repair of the common hepatic artery aneurysm."
