Optic papillitis, unspecified eye

This code describes inflammation of the optic disc, the portion of the optic nerve visible within the eye, without specifying which eye is affected. This condition can lead to sudden vision loss, visual field defects, and swelling of the optic nerve head. It is often associated with demyelinating diseases, infections, or autoimmune conditions.

Use this code when the medical record documents optic papillitis but does not specify laterality (left or right eye). This diagnosis is typically made based on ophthalmoscopic examination revealing a swollen optic disc, often accompanied by visual acuity changes and afferent pupillary defect. Supporting documentation should include findings from an ophthalmological examination.

• Avoid using this code if the medical record clearly specifies the affected eye; instead, use H46.01 (right eye) or H46.02 (left eye).
• Always look for an underlying cause (e.g., multiple sclerosis, infection) and code it as a primary diagnosis if applicable, with optic papillitis as a secondary diagnosis.
• Ensure the documentation differentiates optic papillitis from papilledema, which is optic disc swelling due to increased intracranial pressure.
