Benign neoplasm of bones of skull and face

This code signifies the presence of a non-cancerous growth originating from the bony structures of the skull or facial bones, excluding the mandible. These are typically slow-growing lesions that do not spread to other parts of the body. Examples include osteomas, fibrous dysplasia, or benign giant cell tumors affecting the cranium, maxilla, nasal bones, or zygoma.

Apply this code when documentation confirms a benign neoplasm located in any bone of the skull or face, such as the frontal, parietal, temporal, occipital, sphenoid, ethmoid, nasal, lacrimal, palatine, or zygomatic bones. This diagnosis is often established through imaging studies (e.g., CT, MRI) and sometimes confirmed by biopsy.

• Carefully review documentation to ensure the neoplasm is explicitly stated as benign and its location is within the skull or facial bones, excluding the lower jaw.
• Distinguish this code from malignant neoplasms of these sites, which would be classified under C41.0 or C41.1.
• Always confirm the specific bone involved; if the lower jaw (mandible) is affected, a different code is required.
