CPT® Code 35241

The procedure described by CPT® Code 35241 involves the surgical repair of an intrathoracic blood vessel using a vein graft. This complex operation typically requires the chest to be opened, often through a median sternotomy, which is a surgical procedure that involves making an incision along the sternum to access the thoracic cavity. In cases where the injury to the blood vessel is significant, cardiopulmonary bypass may be initiated to maintain blood circulation and oxygenation during the surgery. The injured blood vessel is carefully exposed, and clamps are applied both proximal and distal to the injury site to control any bleeding. The surgeon evaluates the extent of the damage to the blood vessel before proceeding with the repair. A segment of vein, most commonly harvested from the saphenous vein located in the lower leg, is prepared for use as a graft. The edges of the damaged blood vessel are debrided to ensure a clean surface for the graft. The prepared vein graft is then meticulously sewn to the ends of the injured blood vessel, allowing for restoration of blood flow. After the clamps are released, the surgical team checks for hemostasis along the suture line to ensure there is no further bleeding. If cardiopulmonary bypass was utilized during the procedure, the patient is carefully taken off bypass. Finally, the overlying tissues are sutured back together in layers to complete the surgical repair. It is important to note that CPT® Code 35241 is specifically used for repairs performed with cardiopulmonary bypass, while CPT® Code 35246 is designated for repairs conducted without the use of bypass.
