CPT® Code 34834

Add-On Code

Open brachial artery exposure for delivery of endovascular prosthesis, unilateral (List separately in addition to code for primary procedure)

The procedure described by CPT® Code 34834 involves the surgical exposure of the brachial artery to facilitate the delivery of an endovascular prosthesis. This procedure is performed unilaterally, meaning it is conducted on one side of the body. The brachial artery, located in the upper arm, is carefully accessed through an incision, ensuring that surrounding nerves and blood vessels are adequately protected and mobilized to prevent any damage. The dissection of the brachial artery is performed over a length of approximately 5 to 6 centimeters, allowing for sufficient access to the artery. Once exposed, the artery is secured using vessel loops to maintain its position during the procedure. An incision is then made in the brachial artery itself, through which guidewires, sheaths, and catheters are introduced as necessary to assist in the delivery of the endovascular prosthesis. This prosthesis is typically utilized for repairs related to defects in the aorta or iliac arteries. After the endovascular procedure is completed, the brachial artery is meticulously repaired, followed by a layered closure of the surgical wound. It is important to note that this code is reported separately in addition to the code for the primary procedure being performed.
