What 35182 covers
This service is the operative correction of an abnormal artery-to-vein connection that is congenital and located in the thoracic or abdominal region. A vascular surgeon or another surgeon with relevant vascular expertise performs the repair, typically in a hospital operating room. The operative approach and any vessel reconstruction depend on the fistula’s anatomy and the structures involved. This code is distinct from repair of an acquired fistula and from congenital fistula repair in the head, neck, or extremities.
Select the code when the record establishes both congenital origin and a thoracic or abdominal site. The operative report should identify the location and document the repair performed. This major operation has a 90-day global period, including the day-before preoperative visit and 90 days of related postoperative care. When multiple procedures occur in the same session, the highest-valued procedure is paid in full and other procedures are subject to the standard 50% reduction. Modifier 50 is inappropriate. Assistant-at-surgery payment may be available; co-surgeon payment requires supporting documentation, and team surgery is not permitted.
