CPT® Code 36870

Thrombectomy, percutaneous, arteriovenous fistula, autogenous or nonautogenous graft (includes mechanical thrombus extraction and intra-graft thrombolysis)

The CPT® Code 36870 refers to a percutaneous thrombectomy procedure specifically targeting an arteriovenous fistula, which can involve either autogenous or nonautogenous grafts. This procedure is designed to remove thrombus, or blood clots, that may obstruct blood flow within the fistula. The term 'thrombectomy' indicates the surgical removal of a thrombus, and in this context, it is performed using a catheter-based approach. The procedure incorporates mechanical thrombus extraction techniques, which may include the use of specialized devices that either fragment the thrombus or retrieve it entirely. The use of intra-graft thrombolysis may also be involved, where thrombolytic agents are administered to dissolve the clot. The percutaneous nature of this procedure means that it is performed through the skin, minimizing the need for larger incisions and allowing for a less invasive approach to treating clot-related complications in vascular access sites. The overall goal of the procedure is to restore patency to the arteriovenous fistula, thereby ensuring adequate blood flow for dialysis or other medical needs.
