CPT® Code 35256

The procedure described by CPT® Code 35256 involves the surgical repair of a blood vessel in the lower extremity using a vein graft. This procedure is typically indicated when there is an injury to a blood vessel in the leg that requires reconstruction to restore proper blood flow. The approach taken during the surgery is contingent upon the specific blood vessel that has sustained damage. Initially, the injured blood vessel is accessed surgically, and clamps are applied both proximal and distal to the site of injury. This clamping is crucial as it helps to control any bleeding that may occur during the procedure. In some cases, to maintain blood flow to the area while the repair is being performed, a temporary shunt may be placed. Once the area is adequately prepared, the extent of the injury is carefully assessed. A segment of vein, often harvested from the saphenous vein located in the lower leg, is then prepared for use as a graft. The edges of the damaged blood vessel are debrided to ensure a clean surface for the grafting process. The prepared vein graft is meticulously sewn to both the proximal and distal ends of the injured blood vessel, effectively bridging the gap created by the injury. After the graft is secured, the temporary shunt is removed, and the clamps are released. At this stage, the surgical team checks for hemostasis along the suture line to ensure that there is no further bleeding. Finally, the overlying tissues are sutured back together in layers to complete the procedure, ensuring that the surgical site is properly closed and that healing can begin.
