What 46270 covers

This service treats a superficial anal fistula whose tract is confined to tissue beneath the skin around the anus. The surgeon opens or excises the tract to treat the fistula. Colorectal and general surgeons typically perform the procedure in an operating room or ambulatory surgery setting. The operative note should establish the tract’s course and its relationship to the sphincter muscles.

Select this code by the documented anatomy and extent of the fistula, not simply by the fact that a fistula was treated. A tract involving the sphincter or a complex course points to a different code. The 90-day global period includes the day-before preoperative visit and 90 days of related postoperative care. When multiple procedures are performed 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 for this service. Medicare does not pay an assistant at surgery; 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.

46270 billing questions

How does 46270 differ from 46275?

46270 is for a fistula confined to subcutaneous tissue. Use 46275 when the documented tract is intersphincteric.

When is 46280 a better fit?

46280 describes treatment of a complex anal fistula. Choose based on the documented tract anatomy and complexity rather than the procedure name alone.

Can 46270 be reported with modifier 50?

No. The anatomy and service do not support bilateral adjustment, so modifier 50 is inappropriate.

What documentation supports 46270?

Document the fistula tract’s course, its depth and relationship to the sphincter muscles, and the surgical treatment performed.

Are related postoperative visits separately reported?

Related postoperative care during the 90-day global period is included, as is the day-before preoperative visit.

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.
