What 46258 covers

This service combines excision of one internal and external hemorrhoid group with surgical removal of an anal fistula. It is typically performed by a colorectal surgeon or general surgeon in an operating room or ambulatory surgery center when both conditions are treated in the same operation. The hemorrhoid component is limited to one column or group; the fistulectomy is part of the service described by this code.

Select this code when the operative report supports treatment of one hemorrhoid group and fistulectomy, rather than fissurectomy or treatment of multiple groups. Document the hemorrhoid site and extent, the fistula treated, and the procedures actually performed. The 90-day global period includes the day-before preoperative visit and 90 days of related postoperative care. For multiple procedures in the same session, the highest-valued procedure is paid in full and additional procedures at 50%. Modifier 50 is inappropriate for this single-group service. Assistant-at-surgery payment requires documented medical necessity; co-surgeon and team-surgery payment are not permitted.
