What 46030 covers
This service covers removing a noncutting seton from an anal fistula tract, often after it has maintained drainage or controlled inflammation. A colorectal or general surgeon may remove a loose seton in an office or procedure setting, or during an operative encounter. The service is removal only; placement of a seton or operative treatment of the fistula describes different work.
Document the seton’s removal and the clinical status of the fistula tract. The code has a 0-day global period, so same-day preoperative and postoperative care is included. When multiple procedures are performed in the same session, the highest-valued procedure is paid in full and the others at 50%. Modifier 50 is inappropriate for this service. Assistant-at-surgery payment requires documentation of medical necessity; co-surgeons and team surgery are not permitted.

46030 billing questions
How is removal different from seton placement?
46030 describes taking out a noncutting seton. Use 46020 when the service is placement of a seton.
Is this the code for fistulotomy or definitive fistula surgery?
No. Report 46030 for seton removal itself; operative fistula treatment, such as fistulotomy, is a different service.
Can modifier 50 be reported?
No. CMS identifies bilateral adjustment as inappropriate for this code.
How are same-session procedures paid?
The highest-valued procedure is paid in full, and other procedures in the same session are subject to the standard multiple procedure reduction.
What documentation supports reporting 46030?
Document that a noncutting anal seton was removed and describe the fistula tract’s status. Same-day preoperative and postoperative care is included in the 0-day global period.
Can an assistant surgeon or co-surgeon be reported?
Assistant-at-surgery payment requires documentation of medical necessity. Co-surgeons and team surgery are not permitted.
