Low Anterior Resection with Sigmoidoscopy
The patient underwent open low anterior resection, takedown and repair of a chronically incarcerated ventral incisional hernia. During the procedure, an anastomosis was performed utilizing the left colon and the remainder of the proximal sigmoid at the level of the pelvic brim. After completion of the operative procedures, the surgeon performed a limited rigid sigmoidoscopy to the level of the anastomosis to test for anastomotic leaks. There were no leaks identified. Is it appropriate to assign a separate code for the rigid sigmoidoscopy performed to check the anastomosis? ...

Article Overview
This premium coding article examines a postoperative coding question arising in colorectal surgery, specifically whether an additional endoscopic service can be separately reported when used to inspect a completed anastomosis after a major abdominal operation. It is relevant to coders, auditors, and surgical billing staff working with gastrointestinal procedures and CPT guidance, especially where operative documentation describes leak testing or limited endoscopic inspection after the primary procedure. The article focuses on the coding rationale and procedure-context considerations, without providing a general coding tutorial.
Why This Topic Matters
Situations involving inspection of a completed surgical site can affect whether an additional service is reportable, which has implications for code selection, claim accuracy, and audit risk in surgical coding workflows.
