Official Description

Repair blood vessel with vein graft; intrathoracic, with bypass

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

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.

1. Indications

The procedure associated with CPT® Code 35241 is indicated for the repair of an intrathoracic blood vessel that has sustained injury. This may occur due to various conditions, including trauma, aneurysms, or other vascular diseases that compromise the integrity of the blood vessel. The need for surgical intervention arises when the injury is significant enough to require a graft to restore normal blood flow and prevent complications such as hemorrhage or ischemia.

  • Trauma Injury to the intrathoracic blood vessel due to blunt or penetrating trauma.
  • Aneurysms Presence of an aneurysm that necessitates repair to prevent rupture.
  • Vascular Diseases Conditions affecting the blood vessels that lead to significant damage requiring surgical intervention.

2. Procedure

The surgical procedure for CPT® Code 35241 involves several critical steps to ensure the successful repair of the injured blood vessel.

  • Step 1: Accessing the Thoracic Cavity The procedure begins with the patient being placed under general anesthesia. The surgeon makes an incision in the chest, typically through a median sternotomy, to gain access to the intrathoracic structures.
  • Step 2: Initiating Cardiopulmonary Bypass If the nature of the injury requires it, cardiopulmonary bypass is initiated to maintain blood circulation and oxygenation while the surgery is performed. This involves connecting the patient to a heart-lung machine.
  • Step 3: Exposing the Injured Blood Vessel The injured blood vessel is carefully exposed, and clamps are applied both proximal and distal to the injury site. This clamping is essential to control bleeding and provide a clear field for repair.
  • Step 4: Evaluating the Injury The surgeon evaluates the extent of the injury to determine the appropriate course of action for repair. This assessment is crucial for ensuring that the graft will adequately restore blood flow.
  • Step 5: Harvesting the Vein Graft A segment of vein, usually the saphenous vein from the lower leg, is harvested and prepared for grafting. This vein is selected for its suitability in providing a durable and effective graft.
  • Step 6: Debriding the Blood Vessel The edges of the injured blood vessel are debrided to remove any damaged tissue, ensuring a clean surface for the graft to adhere to.
  • Step 7: Attaching the Vein Graft The prepared vein graft is sewn to the proximal and distal ends of the injured blood vessel, effectively bridging the gap and restoring continuity of blood flow.
  • Step 8: Releasing Clamps and Checking Hemostasis After the graft is securely in place, the clamps are released, and the surgical team checks for hemostasis along the suture line to ensure there is no bleeding.
  • Step 9: Weaning Off Cardiopulmonary Bypass If cardiopulmonary bypass was used, the patient is carefully weaned off the machine, and normal circulation is restored.
  • Step 10: Closing the Surgical Site Finally, the overlying tissues are sutured back together in layers, completing the surgical repair and ensuring proper healing.

3. Post-Procedure

Post-procedure care following the repair of an intrathoracic blood vessel with a vein graft involves close monitoring of the patient for any signs of complications, such as bleeding or infection. The patient may require intensive care initially, especially if cardiopulmonary bypass was utilized. Pain management is also an important aspect of post-operative care. The surgical site will be monitored for proper healing, and follow-up imaging may be necessary to assess the success of the graft. Patients are typically advised on activity restrictions and may undergo rehabilitation to aid recovery and restore normal function.

58 Staged or related procedure or service by the same physician or other qualified health care professional during the postoperative period: it may be necessary to indicate that the performance of a procedure or service during the postoperative period was: (a) planned or anticipated (staged); (b) more extensive than the original procedure; or (c) for therapy following a surgical procedure. this circumstance may be reported by adding modifier 58 to the staged or related procedure. note: for treatment of a problem that requires a return to the operating/procedure room (eg, unanticipated clinical condition), see modifier 78.
59 Distinct procedural service: under certain circumstances, it may be necessary to indicate that a procedure or service was distinct or independent from other non-e/m services performed on the same day. modifier 59 is used to identify procedures/services, other than e/m services, that are not normally reported together, but are appropriate under the circumstances. documentation must support a different session, different procedure or surgery, different site or organ system, separate incision/excision, separate lesion, or separate injury (or area of injury in extensive injuries) not ordinarily encountered or performed on the same day by the same individual. however, when another already established modifier is appropriate it should be used rather than modifier 59. only if no more descriptive modifier is available, and the use of modifier 59 best explains the circumstances, should modifier 59 be used. note: modifier 59 should not be appended to an e/m service. to report a separate and distinct e/m service with a non-e/m service performed on the same date, see modifier 25.
