What 45300 covers
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.

45300 billing questions
How does 45300 differ from diagnostic flexible sigmoidoscopy?
45300 is for examination with a rigid scope. Use 45330 when the examination is performed with a flexible sigmoidoscope.
Can brushing or washing be reported separately?
No. Brushing or washing specimen collection is included in 45300 when performed.
Can a biopsy be reported as 45300?
No. A biopsy is a distinct service; 45305 describes rigid proctosigmoidoscopy with biopsy.
What should the procedure note support?
Document the diagnostic indication, rigid scope examination and findings, and whether brushing or washing was performed.
How does the multiple-procedure rule affect payment?
For procedures in the same session, the highest-valued procedure is paid in full and the others are subject to the standard 50% 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.
