What 45520 covers

This service covers a treatment directed at rectal prolapse without the formal abdominal or perineal repair described by the related repair codes. A colorectal or general surgeon may perform a local treatment, such as injection therapy, in an outpatient setting. The record should identify the prolapse and the treatment method performed so the service can be distinguished from repair of the rectum or surgery to correct prolapse through an abdominal or perineal approach.

Report the service based on the treatment actually performed, not simply the diagnosis of prolapse. CMS assigns a 0-day global period, so same-day preoperative and postoperative care is 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 code. Medicare does not pay an assistant at surgery; co-surgeons and team surgery 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.

45520 billing questions

When should this code be chosen over a prolapse repair code?

Use it for a local treatment, such as injection therapy, rather than a formal abdominal or perineal repair. Select a repair code when the operative service matches that approach and repair.

What documentation supports reporting this service?

Document the rectal prolapse, the method used to treat it, and the work performed. The record should make clear that the service was not an abdominal or perineal repair.

Is same-day care included in the service?

Yes. The 0-day global period includes same-day preoperative and postoperative care.

Can modifier 50 or an assistant-at-surgery claim be reported?

Modifier 50 is inappropriate for this code. Medicare does not pay an assistant at surgery, and co-surgeons and team surgery are not permitted.

How is this code affected when another procedure is 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.

Where these rates come from

FeeBase calculates base physician payments from CMS work, practice-expense and malpractice RVUs, adjusted by each locality’s geographic indexes and the conversion factor. Services without a published rate are labeled, never given a made-up amount. Amounts are Medicare allowed amounts before claim adjustments: not a patient’s bill or a commercial rate.
