Other benign neuroendocrine tumors

This code represents the presence of a non-cancerous tumor originating from neuroendocrine cells, located in an unspecified or "other" site not covered by more specific D3A subcategories. These tumors typically grow slowly and do not metastasize, but can produce hormones leading to various clinical syndromes.

Apply this code when documentation confirms a benign neuroendocrine tumor in a site not otherwise specified (e.g., adrenal medulla, pituitary, pancreas, gastrointestinal tract) or when the specific site is unknown. This code is appropriate when the pathology report definitively states "benign neuroendocrine tumor" without further site specificity or when the tumor is in a less common neuroendocrine location.

• Always seek a more specific code if the anatomical site of the benign neuroendocrine tumor is documented (e.g., D3A.0-D3A.1).
• Do not use this code for malignant neuroendocrine tumors; refer to the C7A category for those.
• Code any associated functional syndromes (e.g., Cushing's syndrome, carcinoid syndrome) as additional diagnoses.
