CPT® Code 35685

Add-On Code

Placement of vein patch or cuff at distal anastomosis of bypass graft, synthetic conduit (List separately in addition to code for primary procedure)

The CPT® Code 35685 refers to the procedure involving the placement of a vein patch or cuff at the distal anastomosis of a bypass graft that utilizes a synthetic conduit. This procedure is performed during a separately reportable arterial bypass operation and is intended to enhance the patency, or openness, of the synthetic bypass graft. The vein patch or cuff serves as an additional support structure at the connection point where the synthetic graft meets the artery, thereby potentially improving blood flow and reducing the risk of complications associated with graft failure. Two primary techniques are utilized for this procedure: the Taylor patch technique and the Miller cuff technique. In the Taylor patch technique, a small segment of the patient's own vein is harvested and then sutured to the artery at the distal anastomosis site, followed by the attachment of the synthetic graft to this vein patch. Conversely, the Miller cuff technique involves creating a short cuff from the harvested vein that is directly sutured to the artery, with the synthetic graft then attached to this cuff. Both techniques aim to optimize the surgical outcome by ensuring a secure and effective connection between the synthetic graft and the arterial system.
