Anorectal endoscopy
About 46606: Anoscopy with tissue biopsy
Report this service when standard anoscopy is used to inspect the anal canal and obtain one or more tissue biopsies for pathologic examination.
A clinician examines the anal canal through an anoscope and takes one or more tissue samples from an abnormal area for pathologic evaluation. Colorectal surgeons and gastroenterologists commonly perform this service in an office or procedure room when inspection identifies tissue that needs histologic assessment, such as a suspicious mucosal lesion or ulcer. The biopsy distinguishes this service from diagnostic anoscopy without tissue sampling and from procedures that remove or ablate a lesion.
Report the code when the documented service includes tissue biopsy; record the finding and sampling site. Same-day preoperative and postoperative care is included in its 0-day global period. When related endoscopies are performed together, endoscopy family pricing applies, so the procedures are priced under the family rules rather than each being treated as an unrelated service. Modifier 50 is inappropriate for this code. Medicare does not pay an assistant at surgery, and co-surgeon and team-surgery billing are not permitted.

46606 billing questions
When should this be reported instead of 46600?
Report 46606 when anoscopy includes tissue biopsy. Use 46600 for diagnostic inspection without tissue biopsy.
How does 46606 differ from 46607?
Both include biopsy, but 46607 is for diagnostic anoscopy using high-resolution magnification. Report 46606 for biopsy with standard anoscopy.
Can the biopsy be reported separately from the anoscopy?
The biopsy is part of this anoscopy service; do not report a separate code for the tissue sampling itself.
Should modifier 50 be appended for bilateral findings?
No. Bilateral adjustment does not apply, and modifier 50 is inappropriate for this code.
What happens when related endoscopies are performed in the same session?
CMS applies endoscopy family pricing to related endoscopies performed together. Same-day preoperative and postoperative care is included in this code's 0-day global period.
Where these rates come from
FeeBase calculates base physician payments from CMS work, practice-expense, and malpractice RVUs, adjusted by each locality’s geographic indices and the applicable conversion factor. Unavailable or separately priced services are labeled rather than assigned a made-up amount.
