Benign neoplasm of nasopharynx

This code signifies the presence of a non-cancerous tumor originating in the nasopharynx, the upper part of the pharynx located behind the nose. These benign growths are typically slow-growing and do not metastasize to other parts of the body.

Apply this code when documentation confirms a benign neoplasm of the nasopharynx, often identified through imaging studies, endoscopy, or biopsy. This includes conditions like nasopharyngeal angiofibroma or other non-malignant tumors confined to this specific anatomical site.

• Ensure the pathology report explicitly states "benign" for the nasopharyngeal lesion.
• Differentiate carefully from malignant neoplasms of the nasopharynx (C11.- series).
• Do not use for inflammatory polyps or cysts unless specifically diagnosed as a benign neoplasm.
