Official Description

Bypass graft, with other than vein; popliteal-tibial or -peroneal artery

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

A bypass graft using other than vein is a surgical procedure performed on the arteries of the lower extremity, specifically targeting the popliteal-tibial or peroneal arteries. This procedure is indicated when there is a need to restore blood flow to the lower leg due to blockages or narrowing of the arteries that can lead to ischemia or other complications. The surgery involves creating a new pathway for blood to flow, bypassing the obstructed segment of the artery. In this case, the procedure is performed through an incision made behind the knee, allowing access to the popliteal artery. The distal anastomosis site is also prepared, which may involve the anterior tibial, posterior tibial, or peroneal arteries. A synthetic graft is utilized instead of a vein, which is selected based on the size required for the grafting. The graft is then surgically attached to both the proximal and distal ends of the artery, ensuring that blood can flow freely through the newly created bypass. This procedure is critical for patients suffering from peripheral artery disease or other vascular conditions that compromise blood circulation in the lower extremities.

1. Indications

The bypass graft procedure using other than vein is indicated for patients experiencing significant arterial blockages or narrowing in the lower extremities, particularly affecting the popliteal, tibial, or peroneal arteries. The following conditions may warrant this surgical intervention:

  • Peripheral Artery Disease (PAD) - A condition characterized by narrowed arteries reducing blood flow to the limbs, often leading to pain and mobility issues.
  • Critical Limb Ischemia - A severe obstruction of the arteries that significantly reduces blood flow, potentially resulting in pain at rest, non-healing wounds, or gangrene.
  • Rest Pain - Pain in the feet or toes while resting, indicating inadequate blood supply.
  • Non-healing Ulcers or Wounds - Ulcers or wounds on the lower extremities that do not heal due to insufficient blood flow.

2. Procedure

The procedure for a bypass graft with other than vein involves several critical steps to ensure successful grafting and restoration of blood flow. The following procedural steps are performed:

  • Step 1: Incision - An incision is made on the affected side behind the knee to access the popliteal artery. This incision allows the surgeon to expose the artery and prepare for the grafting procedure.
  • Step 2: Exposure of Arteries - The popliteal artery is carefully exposed, and the distal anastomosis site is identified on the anterior tibial, posterior tibial, or peroneal artery. This step is crucial for determining where the graft will connect to restore blood flow.
  • Step 3: Creation of Tunnel - A tunnel is created from the proximal anastomosis site to the distal anastomosis site. This tunnel will facilitate the passage of the synthetic graft from one site to the other.
  • Step 4: Graft Selection and Preparation - An appropriately sized tubular synthetic graft is selected based on the dimensions required for the bypass. The graft is then prepared for surgical implantation.
  • Step 5: Anastomosis of Graft - The synthetic graft is anastomosed to the proximal anastomosis site. The proximal artery is clamped, incised, and the proximal end of the graft is attached securely.
  • Step 6: Distal Anastomosis - The distal artery is similarly clamped and incised, allowing for the distal end of the graft to be anastomosed. This step completes the connection of the graft to both ends of the artery.
  • Step 7: Hemostasis and Blood Flow Check - After the graft is in place, vascular clamps are released, and hemostasis at all anastomosis sites is checked. Blood flow through the graft is assessed using Doppler ultrasound, and distal pulses are evaluated to ensure the patency of the bypass graft.

3. Post-Procedure

Post-procedure care involves monitoring the patient for any signs of complications, ensuring that the graft remains patent, and that blood flow is adequate. Patients may require follow-up imaging studies to assess the success of the graft. Pain management and rehabilitation may also be necessary to aid recovery and improve mobility. Regular follow-up appointments are essential to monitor the patient's progress and to address any potential issues that may arise following the surgery.

22 Increased procedural services: when the work required to provide a service is substantially greater than typically required, it may be identified by adding modifier 22 to the usual procedure code. documentation must support the substantial additional work and the reason for the additional work (ie, increased intensity, time, technical difficulty of procedure, severity of patient's condition, physical and mental effort required). note: this modifier should not be appended to an e/m service.
51 Multiple procedures: when multiple procedures, other than e/m services, physical medicine and rehabilitation services or provision of supplies (eg, vaccines), are performed at the same session by the same individual, the primary procedure or service may be reported as listed. the additional procedure(s) or service(s) may be identified by appending modifier 51 to the additional procedure or service code(s). note: this modifier should not be appended to designated "add-on" codes (see appendix d).
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.
78 Unplanned return to the operating/procedure room by the same physician or other qualified health care professional following initial procedure for a related procedure during the postoperative period: it may be necessary to indicate that another procedure was performed during the postoperative period of the initial procedure (unplanned procedure following initial procedure). when this procedure is related to the first, and requires the use of an operating/procedure room, it may be reported by adding modifier 78 to the related procedure. (for repeat procedures, see modifier 76.)
79 Unrelated procedure or service by the same physician or other qualified health care professional during the postoperative period: the individual may need to indicate that the performance of a procedure or service during the postoperative period was unrelated to the original procedure. this circumstance may be reported by using modifier 79. (for repeat procedures on the same day, see modifier 76.)
80 Assistant surgeon: surgical assistant services may be identified by adding modifier 80 to the usual procedure number(s).
82 Assistant surgeon (when qualified resident surgeon not available): the unavailability of a qualified resident surgeon is a prerequisite for use of modifier 82 appended to the usual procedure code number(s).
