What 35188 covers

A vascular surgeon typically reports this service for operative treatment of an acquired arteriovenous fistula in the head or neck, such as one resulting from trauma or a prior procedure. The surgeon exposes the abnormal connection and repairs it to interrupt the direct flow between artery and vein. The service is generally performed in a hospital operating room.

Select the code when the operative record supports an acquired fistula and identifies its head-and-neck location; congenital fistulas and fistulas in the thorax, abdomen, or extremities have different codes. The 90-day global includes the day-before preoperative visit and 90 days of related postoperative care. When multiple procedures occur in one session, the highest-valued procedure is paid in full and other procedures are subject to the standard reduction. Modifier 50 is not appropriate for this repair. Assistant-at-surgery payment may be available; co-surgeon payment requires supporting documentation, and team surgery is not permitted.
