CPT® Code 34711

Add-On Code

Delayed placement of distal or proximal extension prosthesis for endovascular repair of infrarenal abdominal aortic or iliac aneurysm, false aneurysm, dissection, endoleak, or endograft migration, including pre-procedure sizing and device selection, all nonselective catheterization(s), all associated radiological supervision and interpretation, and treatment zone angioplasty/stenting, when performed; each additional vessel treated (List separately in addition to code for primary procedure)

The CPT® Code 34711 refers to the delayed placement of a distal or proximal extension prosthesis following an endovascular repair procedure for specific vascular conditions. This procedure is indicated in cases where there is a need to address complications such as an endoleak, endograft migration, or other issues related to infrarenal abdominal aortic or iliac aneurysms, false aneurysms, or dissections. The term 'delayed placement' signifies that this intervention occurs after the initial endovascular repair has been performed, typically when complications arise that necessitate further intervention to ensure the integrity and functionality of the vascular repair. The procedure involves accessing the femoral arteries, utilizing fluoroscopic guidance to navigate catheters and wires to the aorta, and deploying extension grafts to reinforce or repair the existing endograft. This complex intervention requires careful planning, including pre-procedure sizing and device selection, as well as comprehensive radiological supervision and interpretation to ensure successful outcomes. The procedure also includes angioplasty or stenting of the treatment zone when necessary, and it is important to note that each additional vessel treated during this procedure is reported separately using this code in conjunction with the primary procedure code 34710.
