Optic papillitis, bilateral

This diagnosis code signifies inflammation of the optic nerve head (papilla) affecting both eyes. It is a form of optic neuritis characterized by swelling of the optic disc, often leading to visual disturbances. This condition can be idiopathic or associated with systemic diseases.

Apply this code when documentation clearly indicates bilateral optic papillitis, meaning both optic nerves are inflamed and swollen at their entry point into the eye. Supporting documentation should include ophthalmological exam findings such as disc edema, hyperemia, and visual field defects affecting both eyes. This code is appropriate for acute or subacute presentations.

• Ensure the documentation explicitly states "bilateral" involvement; otherwise, consider laterality-specific codes.
• Distinguish from retrobulbar neuritis (H46.1-), where the inflammation is behind the globe and the optic disc appears normal.
• Always code any underlying systemic disease (e.g., multiple sclerosis, sarcoidosis) as a primary or secondary diagnosis, if applicable.
