Ask Dr. Z

Patient came in for calf mass excision, and vascular surgeon was called in to assist. Vascular surgeon harvested saphenous vein graft, then the vein was non-reversed in order to keep proper orientation for the venous reconstruction. An end-to-end venous anastomosis was created using a running 6-0 Prolente suture distally. The vein was then pressurized by releasing the distal control. MD then replaced and bulldog clamp on the saphenous vein segment. Then MD sewed end-to-end venovenous anastomosis with a running 6-0 Prolene suture. Following this, the proximal and distal clamps were removed. The right greater saphenous vein harvest site was irrigated with warm saline solution."

Should we go with unlisted because we can't find another code that would describe such procedure?
