Bypass graft, with vein; tibial-tibial, peroneal-tibial, or tibial/peroneal trunk-tibial.
Modifiers may be applicable, such as 50 for bilateral procedures, or anatomical modifiers (LT, RT) to distinguish laterality.
Medical necessity must be established by documenting the severity of the circulatory impairment, failed conservative treatments, and the expected improvement in limb function or prevention of limb loss.
The surgeon prepares the patient, makes incisions to expose the arteries, creates a path for the graft, harvests the vein graft, connects the graft to the artery above and below the blockage, checks for proper blood flow, and closes the incisions.
In simple words: This procedure creates a detour around a blocked blood vessel in the lower leg using a healthy vein from the patient.The surgeon connects the vein to the artery above and below the blockage, allowing blood to flow freely again.
This procedure involves creating a bypass from the tibial to tibial artery, peroneal to tibial artery, or tibial/peroneal trunk to tibial artery using a vein graft. This is performed to circumvent a blocked or damaged section of the tibial, peroneal, or tibioperoneal trunk artery.
Example 1: A patient with severe peripheral artery disease in the lower leg has a blockage in the tibial artery. A tibial-tibial bypass using a vein graft is performed to restore blood flow., A patient with a traumatic injury to the peroneal artery requires a peroneal-tibial bypass using a vein graft to salvage the limb., A patient with a blockage in the tibioperoneal trunk undergoes a tibial/peroneal trunk-tibial bypass using a saphenous vein graft to improve circulation.
Documentation should include details of the blockage, the reason for the bypass, the type of graft used, operative details, and post-operative assessment of blood flow.
