In simple words: This procedure restores blood flow in the leg arteries (except those below the knee) by breaking up blockages, inserting stents to keep the vessels open, and removing plaque buildup. This is done through a small incision or by inserting a catheter into the artery.

Revascularization, endovascular, open or percutaneous, lower extremity artery(ies), except tibial/peroneal; with intravascular lithotripsy and transluminal stent placement(s), and atherectomy, includes angioplasty within the same vessel(s), when performed.

Example 1: A patient presents with severe blockage in the femoral artery. The physician performs an endovascular procedure using intravascular lithotripsy to fracture the blockage, places a stent to keep the artery open, and performs atherectomy to remove any remaining plaque. Angioplasty is performed within the same vessel to further improve blood flow., A patient with a history of peripheral artery disease experiences recurring claudication in the thigh. The physician performs an open revascularization procedure on the popliteal artery using intravascular lithotripsy, stent placement, and atherectomy to restore blood flow. Angioplasty is performed in the affected vessel to ensure optimal results., A patient undergoes a percutaneous procedure to address a blockage in the iliac artery. Intravascular lithotripsy is used to break up the blockage, followed by stent placement and atherectomy to clear the vessel. Angioplasty is performed within the same vessel to improve blood flow to the leg.

Documentation should include details of the procedure, including the location of the blockage(s), the type of stent used, and any complications encountered. Pre- and post-procedure angiograms should be included to demonstrate the improvement in blood flow. The medical necessity of the procedure, including the patient's symptoms and failed conservative treatments, should be clearly documented.
