Optic papillitis, right eye

This code represents inflammation of the optic nerve head (papilla) specifically affecting the right eye. Optic papillitis is a form of optic neuritis characterized by swelling of the optic disc, often leading to acute vision loss. It can be unilateral or bilateral and may be associated with various underlying systemic conditions or be idiopathic.

Assign this code when documentation clearly indicates a diagnosis of optic papillitis in the right eye. This typically occurs following an ophthalmological examination revealing optic disc edema and associated visual disturbances. Supporting documentation should include findings from fundoscopy, visual field testing, and potentially MRI to rule out other etiologies.

• Ensure laterality is explicitly documented as "right eye" to support this specific code.
• Distinguish from retrobulbar optic neuritis (H46.02-H46.03), where the optic disc appears normal.
• Code any underlying systemic conditions (e.g., multiple sclerosis, autoimmune diseases) as additional diagnoses.
