Bypass graft, with other than vein; popliteal-tibial or -peroneal artery.
Modifiers may be applicable to indicate specific circumstances, such as increased procedural services or bilateral procedures.
Medical necessity for this procedure is established by documenting impaired blood flow to the lower extremity due to popliteal artery blockage, resulting in symptoms such as claudication or critical limb ischemia, where less invasive treatments are unsuitable.
The surgeon performs the bypass procedure, including prepping the patient, making the incision, preparing and attaching the graft, checking for leaks, and confirming graft patency.
In simple words: A synthetic tube is used to create a detour around a blocked artery in the back of the knee, rerouting blood flow to the lower leg.
This procedure involves creating a bypass around a blocked popliteal artery using a synthetic graft. The graft redirects blood flow from the popliteal artery to the tibial or peroneal artery, restoring blood supply to the lower leg.The surgeon makes an incision in the leg, prepares the graft, clamps the affected artery, and attaches the graft above and below the blockage.Patency of the graft is often confirmed via arteriography or ultrasound.
Example 1: A patient with severe peripheral artery disease in the popliteal artery causing claudication undergoes bypass surgery using a synthetic graft to the tibial artery., A patient presents with critical limb ischemia due to a popliteal artery blockage. A synthetic bypass graft to the peroneal artery is performed to salvage the limb., A patient with a failed previous vein graft to the popliteal artery now requires a synthetic bypass graft to the tibial artery to restore blood flow.
Documentation should include details of the blockage, the type of graft used, the location of the bypass, intraoperative findings, and confirmation of graft patency. Preoperative diagnostic tests like angiography or ultrasound should also be documented.
