What 45500 covers

This operation repairs an injured rectum through a proctoplasty approach; the repair may also involve the anorectal sphincter when that structure is injured. It is typically performed by a colorectal or general surgeon in an operating room for a rectal injury requiring operative repair. The operative report should identify the injury and describe the repair performed, including any sphincter repair.

Report 45500 when the documented service is injury-related proctoplasty, rather than reconstruction for rectal narrowing or repair through a different operative approach. The Medicare global period includes the day-before preoperative visit and 90 days of related postoperative care. 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. Assistant-at-surgery payment requires documentation of medical necessity.
