Medicare allowed amount for participating (non-QP) physicians, before deductible, coinsurance and claim adjustments. Not a patient’s bill or a hospital charge.

What 45905 covers

A colorectal or general surgeon dilates the anal sphincter to relieve tightness or spasm, often in a patient with an anal fissure. The procedure addresses the sphincter itself; it is distinct from dilation directed at a narrowing higher in the rectum. It may be performed in a procedural setting or operating room, depending on the patient and technique.

Report the service when the record supports actual sphincter dilation and identifies the indication and the structure treated. Document the relevant examination findings and the procedure performed; an evaluation or examination alone does not establish that dilation occurred. CMS assigns 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 50% multiple-procedure reduction. The anatomy is not suited to modifier 50. Medicare does not pay for an assistant at surgery, and co-surgeon and team-surgery billing are not permitted.

This summary was written with AI assistance from CMS physician fee schedule data and checked against the CMS billing rules shown here. Rates on this page come directly from CMS files.
