Benign carcinoid tumor of the transverse colon

This code signifies a non-malignant neuroendocrine tumor originating in the transverse segment of the large intestine. These tumors are typically slow-growing and arise from enterochromaffin cells. While benign, they have the potential to secrete vasoactive substances, leading to carcinoid syndrome in some cases.

Apply this code when documentation clearly states a benign carcinoid tumor located specifically in the transverse colon. This diagnosis is often established through biopsy and histopathological examination. Use this code for surveillance, treatment of symptoms, or surgical resection of the benign tumor.

• Ensure the documentation specifies "benign" and "transverse colon" to differentiate from malignant or unspecified carcinoid tumors.
• Do not use this code if the tumor is described as malignant or if the specific colon segment is not documented.
• Consider additional codes for any associated carcinoid syndrome (e.g., E34.0) if present and documented.
