Benign neoplasm of orbit

This code signifies the presence of a non-cancerous growth originating within the orbital cavity, the bony structure surrounding the eye. These lesions are typically slow-growing and do not metastasize, but can cause symptoms due to mass effect on ocular structures or nerves.

Apply this code when documentation confirms a benign tumor located within the orbit, such as an orbital hemangioma, neurofibroma, or dermoid cyst. This diagnosis is often established through imaging studies (CT, MRI) and sometimes confirmed by biopsy.

• Differentiate from malignant orbital neoplasms, which are coded to the 190 series.
• Ensure the documentation specifies "benign" to avoid miscoding.
• Consider additional codes for specific symptoms or complications caused by the mass, such as proptosis or vision changes.
