What 46600 covers

A clinician inserts a short anoscope to inspect the anal canal and nearby distal rectum. Colorectal surgeons, gastroenterologists, and other clinicians may perform the exam in an office or outpatient setting to evaluate symptoms such as anal pain or bleeding, or findings such as suspected hemorrhoids, fissures, or an anal canal lesion. Collection of a specimen by brushing or washing can be part of this diagnostic service.

Report 46600 when the anoscopy is diagnostic and does not include a separately defined service such as biopsy, dilation, or lesion removal. Document the indication, examination findings, and any brushing or washing performed. CMS assigns a 0-day global period, so same-day preoperative and postoperative care is included. When multiple procedures are performed in one session, the highest-valued procedure is paid in full and other procedures are subject to the standard 50% reduction. Bilateral adjustment is inappropriate; assistant-at-surgery payment is restricted, and co-surgeon and team-surgery payment 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.

46600 billing questions

When should 46600 be used instead of 46601?

Use 46600 for standard diagnostic anoscopy. Use 46601 when the examination uses high-resolution magnification.

Can brushing or washing be reported separately?

No. Specimen collection by brushing or washing is included in the diagnostic anoscopy service.

Which code applies if the clinician takes a biopsy?

Use 46606 for anoscopy with biopsy without high-resolution magnification, or 46607 when high-resolution magnification and biopsy are performed.

Does 46600 have a postoperative global period?

It has a 0-day global period. Same-day preoperative and postoperative care is included.

How does the multiple-procedure rule affect 46600?

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

Can 46600 be billed with bilateral or surgical-team modifiers?

Bilateral adjustment is inappropriate for this code. Assistant-at-surgery payment is restricted, and co-surgeon and team-surgery payment 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.
