Vascular surgery

About 35188: Acquired head and neck arteriovenous fistula repair

Reports operative repair of an acquired abnormal artery-to-vein connection in the head or neck, rather than a congenital fistula or one at another site.

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.

35188 billing questions

How is this code distinguished from 35180?

35188 is for an acquired head-and-neck fistula. 35180 is the corresponding code for a congenital fistula in that region.

Which code applies when the acquired fistula is outside the head and neck?

Use the acquired-fistula code matching the documented location: 35189 for the thorax or abdomen, or 35190 for an extremity.

What documentation supports reporting 35188?

The operative report should establish that the fistula is acquired, identify its head-and-neck location, and describe the repair performed.

Are related postoperative visits included?

Yes. The 90-day global includes the day-before preoperative visit and 90 days of related postoperative care.

Can modifier 50 be used, and what about assistant or co-surgeon billing?

Modifier 50 is not appropriate for this repair. Assistant-at-surgery payment may be available, while co-surgeon payment requires supporting documentation.

How are other procedures performed in the same session paid?

The highest-valued procedure is paid in full; other procedures in the same session are subject to the standard multiple-procedure reduction.
