Benign carcinoid tumor of the sigmoid colon

This code identifies a non-cancerous neuroendocrine tumor originating in the sigmoid colon. These tumors are typically slow-growing and have a low potential for metastasis. They arise from enterochromaffin cells within the gastrointestinal tract.

Assign this code when documentation confirms a benign carcinoid tumor specifically located in the sigmoid colon. This diagnosis is often made following endoscopic biopsy or surgical resection. Pathology reports confirming the benign nature and specific location are essential.

• Ensure the pathology report explicitly states "benign" and "carcinoid tumor of the sigmoid colon."
• Do not use this code if the tumor is described as malignant or of uncertain behavior; refer to the C7A category for malignant neuroendocrine tumors.
• Verify the specific colon segment; codes exist for other colonic locations (e.g., ascending, transverse, descending).
