CPT® Code 33894

Endovascular stent repair of coarctation of the ascending, transverse, or descending thoracic or abdominal aorta, involving stent placement; across major side branches

The procedure described by CPT® Code 33894 involves the endovascular stent repair of coarctation, which refers to a narrowing of the aorta, a major blood vessel that carries oxygenated blood from the heart to the rest of the body. This specific procedure targets coarctation occurring in the ascending, transverse, or descending thoracic or abdominal aorta. The endovascular approach utilizes a catheter, which is a thin, flexible tube that is inserted into the body through a small incision, typically in the groin area. This method allows for the placement of a stent, a mesh-like device, to widen the narrowed section of the aorta. The coarctation of the aorta is often congenital, meaning it is present at birth, but symptoms may not manifest until later in life. In some instances, the narrowing can result from other factors such as trauma, severe atherosclerosis, or inflammation. The endovascular stent repair is performed under imaging guidance, ensuring precise placement of the catheter and stent. The deployment of a balloon at the tip of the catheter expands the narrowed area, and the stent is then positioned to keep the artery open. This minimally invasive technique is generally preferred over traditional open surgery due to its reduced recovery time and lower risk of complications. However, there remains a possibility that the coarctation may recur, necessitating further intervention. The procedure is critical in preventing serious complications associated with untreated aortic coarctation, which can include life-threatening conditions such as heart failure, stroke, and aneurysms.
