2025 CPT code 35583
(Active) Effective Date: N/A Revision Date: N/A Surgical Procedures on the Cardiovascular System - In-Situ Vein Bypass Graft Procedures Surgery Feed
In-situ vein bypass; femoral-popliteal. This procedure uses the patient's own saphenous vein to create a bypass around a blocked femoral artery, restoring blood flow to the lower leg.
Modifiers may be applicable to indicate specific circumstances, such as bilateral procedures or distinct procedural services. Refer to current CPT guidelines.
Medical necessity is established by documentation of inadequate blood flow to the lower extremity due to arterial blockage, resulting in symptoms such as pain, non-healing ulcers, or gangrene.
The surgeon is responsible for all aspects of the procedure, including incisions, dissection, vein preparation, anastomoses, and closure.
In simple words: This procedure uses a vein from your leg to create a detour around a blocked artery in your leg. This helps restore blood flow to your lower leg and foot.
The surgeon makes incisions in the groin and near the knee to access the femoral and popliteal arteries and the saphenous vein. Branches of the vein are divided, and the vein is left in its original place but its valves are disrupted. The vein is then attached to the arteries above and below the blockage to reroute blood flow.
Example 1: A patient with peripheral artery disease and a blocked femoral artery causing pain and reduced blood flow to the lower leg undergoes this procedure to restore circulation., A diabetic patient with a non-healing ulcer on the foot due to poor blood flow in the femoral artery undergoes this bypass procedure to promote healing., A patient with severe claudication (pain with walking) caused by a blocked femoral artery undergoes this procedure to alleviate symptoms and improve mobility.
Documentation should include the reason for the bypass, the location and severity of the blockage, the condition of the saphenous vein, the details of the bypass procedure, and post-operative assessment of blood flow.
