What 46611 covers

The clinician examines the anal canal with an anoscope and removes a tumor, polyp, or other lesion using a snare. Colorectal surgeons and gastroenterologists commonly perform this focused anorectal procedure in an office procedure room or facility setting. It is distinct from diagnostic-only anoscopy and from removal by other techniques.

Document the lesion treated and the snare technique used. Do not separately report diagnostic anoscopy as though it were a separate service when it is part of the removal. CMS assigns a 0-day global period, so same-day preoperative and postoperative care is included. When related endoscopies are performed together, endoscopy-family pricing applies. Modifier 50 is inappropriate for this anatomy and service. Medicare does not pay an assistant at surgery for this code; 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.

46611 billing questions

When should this code be selected instead of diagnostic anoscopy?

Use this code when the clinician removes a tumor, polyp, or other lesion with a snare. Diagnostic-only examination without snare removal is reported with 46600.

Can diagnostic anoscopy be billed separately on the same encounter?

The examination performed to locate and treat the lesion is part of the snare-removal service, rather than a separate diagnostic anoscopy.

How does this differ from anoscopic lesion removal with cautery?

This code identifies snare technique. Code 46612 is for lesion removal using hot biopsy forceps or bipolar cautery.

Should modifier 50 be used for lesions on both sides?

No. CMS identifies bilateral adjustment as inappropriate for this code; modifier 50 does not describe this anorectal service.

What staffing and same-day care rules affect payment?

The 0-day global period includes same-day preoperative and postoperative care. Medicare does not pay an assistant at surgery, and co-surgeons and team surgery are not permitted.

What happens when related endoscopies are performed during the same session?

CMS endoscopy-family pricing applies when related endoscopies are performed together. The record should identify the services performed and the lesion-removal technique.

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.
