CPT® Code 34715

Add-On Code

Open axillary/subclavian artery exposure for delivery of endovascular prosthesis by infraclavicular or supraclavicular incision, unilateral (List separately in addition to code for primary procedure)

The procedure described by CPT® Code 34715 involves the surgical exposure of the axillary or subclavian artery through an incision made either below (infraclavicular) or above (supraclavicular) the clavicle. This exposure is essential for the delivery of an endovascular prosthesis, which is a device used to treat vascular conditions. The procedure may also be performed to facilitate cardiopulmonary bypass, a technique that temporarily takes over the function of the heart and lungs during surgery. The process begins with a careful incision in the skin, followed by meticulous dissection of the surrounding tissues to access the artery while protecting adjacent veins and nerves. The surgeon dissects the arterial branches and controls any bleeding that may occur using ligation or electrocautery. The axillary or subclavian artery is then freed from surrounding tissues over a length of approximately 5-6 cm and secured with vessel loops to maintain its position. Once adequately exposed, the artery is clamped and incised to allow for the insertion of a conduit, which is tailored to fit the artery and anastomosed accordingly. This conduit may be used for the delivery of an endovascular prosthesis or for establishing cardiopulmonary bypass. After the procedure, the clamps are removed, and any vascular leaks at the anastomosis site are reinforced with sutures. It is important to note that this procedure is unilateral and is reported separately in addition to the primary procedure, as indicated by the CPT® guidelines.
