CPT® Code 35081

Direct repair of aneurysm, pseudoaneurysm, or excision (partial or total) and graft insertion, with or without patch graft; for aneurysm, pseudoaneurysm, and associated occlusive disease, abdominal aorta

The CPT® Code 35081 refers to the surgical procedure for the direct repair of an abdominal aortic aneurysm or pseudoaneurysm, which may also involve excision (either partial or total) and the insertion of a graft, with or without the use of a patch graft. An abdominal aortic aneurysm is characterized by an abnormal enlargement or dilation of the abdominal aorta, which can lead to serious complications if not addressed. The causes of such aneurysms can include arteriosclerosis, mechanical obstructions like thoracic outlet syndrome, or malposition of the artery. Less frequently, conditions such as syphilis, tuberculosis, or abnormalities in the vessel wall, such as fibromuscular dysplasia, may also contribute to the formation of an aneurysm. In contrast, a pseudoaneurysm is a different entity; it does not involve all three layers of the arterial wall and is often the result of trauma—either blunt or penetrating—or complications from medical procedures, such as catheterization. This results in a pulsating hematoma that is encapsulated and communicates directly with the artery wall. The abdominal aorta itself is a critical vessel that extends from the thoracic aorta, traversing the abdominal cavity and bifurcating into the iliac arteries, which supply blood to the lower body. During the procedure, a midline abdominal incision is typically made to access the aorta, allowing for the careful dissection of surrounding tissues and the establishment of control over blood flow to facilitate the repair. The procedure is generally performed in a nonemergent, elective setting, distinguishing it from other codes that may pertain to emergency situations, such as the repair of a ruptured aneurysm.
