Endoscopy
About 45300: Rigid diagnostic proctosigmoidoscopy
Reports rigid-scope examination of the rectum and distal sigmoid for diagnostic evaluation, including brushing or washing specimen collection when performed.
A physician passes a rigid scope through the anus to examine the rectum and distal sigmoid, commonly to evaluate rectal bleeding, pain, or a suspected distal lesion. Brushing or washing to collect specimens is included when performed. Gastroenterologists and colorectal surgeons may perform the examination in an office or facility setting.
Select this code for a diagnostic rigid examination; a documented biopsy or therapeutic maneuver may call for a different procedure code. The report should identify the indication, examination findings, and any brushing or washing performed. The service has a 0-day global period, so same-day preoperative and postoperative care is included. When multiple procedures occur in the same session, the highest-valued is paid in full and others are subject to the standard 50% reduction. Modifier 50 is inappropriate; assistant-at-surgery payment is restricted, and co-surgeon and team-surgery payment are not permitted.
