What 46940 covers
This code describes procedural management of an anal fissure that includes dilation of the anal sphincter, such as manual or balloon dilation, without fissurectomy. A surgeon, commonly a colorectal or general surgeon, may perform the treatment for a symptomatic fissure in an outpatient or facility setting. The record should identify the fissure and describe the treatment performed, including the dilation method and whether fissure tissue was excised.
Report 46940 when the documented service meets this treatment approach; use the related fissure code when fissurectomy is performed. The service has a 10-day global period, so related postoperative visits during that 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 multiple-procedure reduction. 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.
