Benign carcinoid tumor of the rectum

This code signifies a non-cancerous neuroendocrine tumor originating in the rectum. These tumors are typically slow-growing and arise from enterochromaffin cells within the rectal wall. While benign, they have the potential for local growth and, in rare instances, can metastasize.

Use this code when documentation explicitly states a diagnosis of a benign carcinoid tumor located in the rectum. This diagnosis is typically confirmed through biopsy and histopathological examination. It applies to cases where the tumor is localized and has not demonstrated malignant behavior or distant spread.

• Ensure the pathology report confirms "benign" and "carcinoid tumor" specifically of the "rectum."
• Do not use this code for malignant carcinoid tumors; refer to the C7A.0xx series for malignant neuroendocrine tumors.
• Verify the exact anatomical site; D3A.02x codes differentiate by specific intestinal locations.
