CPT® Code 35700

Add-On Code

Reoperation, femoral-popliteal or femoral (popliteal)-anterior tibial, posterior tibial, peroneal artery, or other distal vessels, more than 1 month after original operation (List separately in addition to code for primary procedure)

The CPT® Code 35700 refers to a reoperation procedure involving the femoral-popliteal or femoral (popliteal)-anterior tibial, posterior tibial, peroneal artery, or other distal vessels. This procedure is specifically indicated when a patient requires a second surgical intervention more than one month after the original arterial bypass operation. The need for reoperation often arises due to complications such as stenosis, which is a narrowing of the graft or the inflow and outflow arteries, leading to re-occlusion and potential graft failure. During this procedure, the physician makes an incision over the previously placed bypass graft to access the affected area. The graft, along with the inflow and outflow arteries, is meticulously dissected from the surrounding tissues to ensure proper identification and mobilization of new sites for the bypass. A new inflow site is selected and mobilized proximal to the original anastomosis, while a new outflow site is identified and mobilized distal to the original anastomosis. The reoperation may involve placing a new bypass graft or performing an in-situ bypass, which is a separately reportable procedure. This code is utilized in conjunction with the primary procedure code to accurately reflect the surgical intervention performed.
