Vascular surgery
About 35189: Acquired thoracoabdominal arteriovenous fistula repair
Open vascular surgery to close an acquired artery-to-vein communication in the thorax or abdomen, reported when operative repair targets that site.
This code describes operative repair of an acquired abnormal connection between an artery and a vein located in the thorax or abdomen. Such fistulas may follow trauma or a prior procedure. A vascular surgeon typically performs the repair in an operating room, using an approach suited to the affected vessels and the fistula’s location. The operative report should establish that the fistula is acquired and identify its thoracic or abdominal site.
Report the service for the repair itself, not for a congenital fistula or one in the head, neck, or extremity. The service 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 multiple-procedure reduction. Modifier 50 is inappropriate. Assistant-at-surgery payment may be available; co-surgeon payment requires supporting documentation, and team surgery is not permitted.

35189 billing questions
How do I distinguish this code from the congenital thoracoabdominal fistula repair code?
Use this code for an acquired fistula. The corresponding congenital code, 35182, is for a fistula documented as congenital.
Which anatomic sites qualify?
The fistula must be in the thorax or abdomen. Fistulas in the head or neck and in an extremity are represented by separate site-specific codes.
Can modifier 50 be used for bilateral repair?
No. The CMS facts specify that bilateral adjustment does not apply and modifier 50 is inappropriate for this code.
What postoperative care is included?
The 90-day global period includes the day-before preoperative visit and 90 days of related postoperative care.
Can an assistant or co-surgeon be paid?
Assistant-at-surgery payment may be made. Co-surgeon payment requires supporting documentation; team surgery is not permitted.
How does CMS handle other procedures performed in the same session?
The highest-valued procedure is paid in full, and other procedures are subject to the standard multiple-procedure reduction.
