CPT code 0505T represents an endovascular femoral–popliteal stent placement performed via a catheter introduced through a venous access site, with comprehensive intraprocedural imaging, mapping and radiological supervision and interpretation. The code captures a specialized technique used to treat peripheral arterial disease, severe limb ischemia, or disabling claudication in the lower extremity by restoring arterial blood flow through the femoral–popliteal segment. This procedure is clinically significant given the burden of peripheral arterial disease nationally and the importance of minimally invasive options that can reduce recovery time and limb loss risk.
