CPT code 46607: Anoscopy, high-resolution exam with biopsy2026 Medicare rate & RVUs in Texas

What 46607 covers
This service uses high-resolution magnification to inspect the anal canal and obtain one or more tissue samples from areas that look abnormal. It is commonly performed by colorectal surgeons and other clinicians trained in high-resolution anoscopy to evaluate findings such as abnormal anal cytology or suspected anal dysplasia. The magnified examination helps identify areas for biopsy; routine anoscopy with biopsy does not include this high-resolution component.
Report the code when the documented service includes both high-resolution anoscopy and biopsy. The record should identify the reason for examination, use of magnification, relevant findings, biopsy sites, and whether tissue was collected. The 0-day global period includes same-day preoperative and postoperative care. When related endoscopies are performed together, endoscopy-family pricing applies. A bilateral modifier is inappropriate. Medicare does not pay an assistant at surgery for this service, and co-surgeons and team surgery are not permitted.

How to choose
- 46606Anoscopy biopsyBiopsy performed
- Choose 46607 when the biopsy is performed during high-resolution magnified anoscopy. Choose 46606 for anoscopy with biopsy without that high-resolution component.
- 46601AnoscopyHigh-resolution, without biopsy
- 46601 describes high-resolution anoscopy without biopsy. When tissue is collected during the high-resolution examination, 46607 captures the combined service.
- 46600Diagnostic anoscopyStandard visualization, optional washing
- 46600 is diagnostic anoscopy without high-resolution magnification or biopsy. It does not represent the magnified examination and tissue collection included in 46607.
46607 billing questions
How does this differ from anoscopy with biopsy without high-resolution magnification?
This code includes high-resolution magnification as well as biopsy. Use the standard anoscopy biopsy code when biopsy is performed without that magnified examination.
Can the high-resolution examination be reported separately when a biopsy is taken?
The biopsy code includes the high-resolution examination. Do not separately report the high-resolution anoscopy-only service for the same examination.
Does the code include pathology analysis of the biopsy?
It covers the anoscopy and tissue collection, not the laboratory’s histologic examination of the specimen. Pathology may be reported by the provider or laboratory performing that separate service.
How many units are reported when multiple areas are biopsied?
The code covers single or multiple biopsies during the high-resolution anoscopy session; the number of tissue samples does not determine units.
Can modifier 50 or an assistant-at-surgery modifier be used?
No. CMS identifies bilateral adjustment as inappropriate for this code and does not pay an assistant at surgery for it.
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.
