Anorectal endoscopy

About 46600: Diagnostic anoscopy without tissue biopsy

A clinician examines the anal canal with an anoscope for diagnostic purposes, optionally collecting cells or secretions by brushing or washing.

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.

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.
