In simple words: The doctor uses a thin, flexible tube with a camera and light (sigmoidoscope) to examine the rectum and a portion of the large intestine. They might collect samples for testing if needed.

This code reports a flexible sigmoidoscopy performed for diagnostic purposes.The procedure involves inserting a flexible sigmoidoscope through the anus to examine the rectum and sigmoid colon, extending to the splenic flexure.Specimen collection via brushing or washing may be included. This is considered a separate procedure and should not be reported with certain other codes (45331-45342, 45346, 45347, 45349, 45350).

Example 1: A patient presents with rectal bleeding. The physician performs a flexible sigmoidoscopy to visualize the rectum and sigmoid colon, identifying a small polyp. A biopsy is taken., A patient experiences persistent constipation and abdominal pain. Flexible sigmoidoscopy is performed to assess the rectum and sigmoid colon for any structural abnormalities or inflammatory changes. No significant findings., A patient undergoes a routine colon cancer screening. A flexible sigmoidoscopy is performed to examine the rectum and sigmoid colon. No polyps or other abnormalities were detected.

* Pre-procedure patient preparation details (e.g., bowel prep).* Indication for the procedure (e.g., symptoms, screening).* Description of the procedure including depth of insertion and visualization of the rectum and sigmoid colon.* Findings during the procedure (e.g., presence or absence of abnormalities, polyps, masses).* Specimen collection and pathology results (if applicable).* Post-procedure patient management.

** The depth of insertion and visualization must be documented to ensure proper coding.Appropriate documentation is crucial for accurate reimbursement.
