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.
