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.

This summary was written with AI assistance from CMS physician fee schedule data and checked against the CMS billing rules shown here. Rates on this page come directly from CMS files.

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.

Where these rates come from

FeeBase calculates base physician payments from CMS work, practice-expense and malpractice RVUs, adjusted by each locality’s geographic indexes and the conversion factor. Services without a published rate are labeled, never given a made-up amount. Amounts are Medicare allowed amounts before claim adjustments: not a patient’s bill or a commercial rate.
