CPT® Code 35456

The procedure described by CPT® Code 35456 refers to a transluminal balloon angioplasty performed on the femoral-popliteal artery. This is a minimally invasive surgical technique used to treat blockages or narrowing in the artery that can impede blood flow to the lower extremities. The term "transluminal" indicates that the procedure is performed within the lumen of the artery, utilizing a balloon catheter to dilate the narrowed area. The femoral-popliteal artery is a critical vessel that supplies blood to the thigh and lower leg, and blockages here can lead to significant complications, including pain, ulcers, or even limb loss. During the procedure, the physician makes an incision to access the artery, allowing for direct intervention. A guidewire is then navigated through the artery to the site of the blockage, where a balloon catheter is positioned. Once in place, the balloon is inflated to compress the plaque against the arterial wall, thereby widening the artery and restoring blood flow. This inflation may be repeated multiple times to achieve optimal results. Following the angioplasty, a completion angiography is performed to confirm the success of the procedure and ensure that the artery remains open. The access site is then repaired, and the skin incision is closed, marking the end of the procedure. This technique is essential for improving circulation and alleviating symptoms associated with arterial blockages in the lower extremities.
