ICD-10 Code H46.01 – Optic papillitis, right eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H46.01 – Optic papillitis, right eye
What it is
H46.01 identifies inflammation of the optic nerve head in the right eye. Use it when the chart specifically documents optic papillitis affecting the right optic disc.
Clinical signs
Common findings include decreased vision, pain with eye movement, and optic disc swelling on exam. Clinical features vary; refer to documentation.
When to use this code
Use this code when the provider diagnoses optic papillitis and clearly states the right eye is involved. It may appear in ophthalmology or neurology notes with optic disc inflammation, visual complaints, or abnormal funduscopic findings.
If laterality is documented, code the right eye rather than an unspecified optic neuritis code. Check documentation when the note uses broader terms such as optic neuritis or papilledema.
Do not use for
Do not use H46.01 if the record only says optic neuritis without laterality, or if the swelling is from another cause. Check documentation.
Coding tip
Confirm both the diagnosis term and laterality in the assessment before assigning H46.01.
