What 46080 covers

This procedure divides anal sphincter muscle, most often the internal sphincter in a lateral sphincterotomy for a chronic anal fissure. A colorectal or general surgeon typically performs it in an operating room or outpatient surgical facility. The operative note should identify the indication and describe the sphincter division performed.

Report 46080 when sphincterotomy itself is the service. If the surgeon excises the fissure and performs sphincterotomy as part of that operation, report 46200 rather than separately reporting 46080 for the included sphincterotomy. The 10-day global period includes related postoperative visits during that period. 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% multiple-procedure reduction. Modifier 50 is inappropriate for this code. Medicare does not pay an assistant at surgery, and 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.

46080 billing questions

When should 46080 be reported instead of 46200?

Report 46080 when the service is sphincter division. Use 46200 when the surgeon performs fissurectomy and includes sphincterotomy in that operation; do not separately report 46080 for the included division.

What documentation supports 46080?

Document the indication, the sphincter muscle divided, and the operative technique. For a fissure, the note should make clear that sphincterotomy was performed rather than only an examination or another anorectal procedure.

Can modifier 50 be used for bilateral sphincterotomy?

No. The CMS bilateral adjustment does not apply to 46080, and modifier 50 is inappropriate for this code.

Are postoperative visits separately reportable during the global period?

Related postoperative visits for 10 days are included in the procedure's global period.

How does the multiple-procedure rule affect 46080?

When other procedures are performed in the same session, the highest-valued procedure is paid in full and the other procedures are subject to the standard 50% multiple-procedure reduction.

Can an assistant or co-surgeon be reported?

Medicare does not pay an assistant at surgery for 46080. 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.
