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

What 45900 covers

This service covers reducing prolapsed rectal tissue while the patient is under anesthesia. A surgeon or other qualified physician may perform it in an operating room or procedural setting when the prolapse needs reduction under anesthesia. It describes reduction, not definitive surgical repair of the prolapse.

Report the service when documentation supports both the rectal prolapse and its reduction under anesthesia. The procedure has a 10-day global period, so related postoperative visits during that period are included. When multiple procedures occur in the same session, CMS pays the highest-valued procedure in full and reduces payment for the others by the standard multiple-procedure rule. Modifier 50 is inappropriate for this service. Assistant-at-surgery payment requires documented medical necessity; co-surgeon and team-surgery payment 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.
