Benign carcinoid tumor of the small intestine, unsp portion

This code describes a non-cancerous, slow-growing tumor originating from neuroendocrine cells within the small intestine. These tumors, while benign, can produce hormones and may cause symptoms related to their location or hormonal activity. "Unspecified portion" indicates that the exact segment of the small intestine (duodenum, jejunum, or ileum) is not documented.

Use this code when diagnostic imaging (e.g., CT, MRI, endoscopy) or biopsy confirms a benign carcinoid tumor located in the small intestine, but the specific segment is not identified in the medical record. It is appropriate for initial diagnosis, surveillance, or follow-up of such a tumor when no malignant features are present.

• Ensure the pathology report explicitly states "benign" and "carcinoid tumor" of the small intestine.
• Avoid using this code if the tumor is documented as malignant or of uncertain behavior; instead, refer to the C7A series.
• If the specific portion of the small intestine (e.g., duodenum, jejunum, ileum) is documented, use the more specific D3A.01- subcodes.
