Benign carcinoid tumor of the descending colon

This code signifies a non-malignant neuroendocrine tumor originating in the descending segment of the large intestine. These tumors are typically slow-growing and arise from enterochromaffin cells within the colonic mucosa. While benign, they can still produce hormones and may require surgical resection.

Apply this code when documentation explicitly states a benign carcinoid tumor located in the descending colon. This diagnosis is typically confirmed through biopsy and histopathological examination. Use for patients undergoing surveillance or treatment for this specific, non-metastatic tumor type.

• Ensure the pathology report confirms the benign nature and specific location (descending colon) of the carcinoid tumor.
• Distinguish from malignant carcinoid tumors (C7A.0xx series) or carcinoid tumors of unspecified behavior (D3A.09).
• Do not use for carcinoid tumors in other colonic segments; specify the correct anatomical site.
