Benign carcinoid tumor of the hindgut, unspecified

This code represents a non-cancerous, slow-growing neuroendocrine tumor originating in the hindgut (distal colon, rectum, or anus) that has not been further specified regarding its exact location or behavior. These tumors arise from enterochromaffin cells and typically produce hormones, though they are often asymptomatic.

Use this code when documentation confirms a benign carcinoid tumor located in the hindgut, and no further specificity regarding the exact anatomical site within the hindgut is provided. This code is appropriate when the pathology report definitively states "benign carcinoid tumor" and specifies the hindgut as the origin.

• Ensure the documentation explicitly states "benign" and "carcinoid tumor" of the hindgut.
• Avoid using this code if a more specific anatomical site within the hindgut (e.g., rectum, sigmoid colon) is documented; instead, use the more precise D3A.09x code.
• Do not use this code for malignant carcinoid tumors; refer to the C7A category for malignant neuroendocrine tumors.
