What 46900 covers
This code covers destruction of simple lesions on the anus, including lesions such as condyloma, papilloma, or molluscum contagiosum. A colorectal or general surgeon commonly performs the service in an office or outpatient setting. The treatment destroys the lesion rather than removing it as a specimen for excisional pathology. The distinction from more extensive treatment and from technique-specific procedures is central to code selection.
Document the lesion location, number and extent, the destruction performed, and why the service meets the simple-lesion level. Report the code for the session’s service rather than treating each lesion as a separate unit. Related postoperative visits during the 10-day global period are included. When multiple procedures are performed in the same session, the highest-valued procedure is paid in full and other procedures are subject to the standard 50% multiple-procedure reduction. Modifier 50 is inappropriate for this anal-site service. Medicare does not pay an assistant at surgery, and co-surgeons and team surgery are not permitted.
