ICD-10 Code H47.233 – Glaucomatous optic atrophy, bilateral (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H47.233 – Glaucomatous optic atrophy, bilateral
What it is
This code identifies optic nerve damage from glaucoma in both eyes. It reflects glaucomatous optic atrophy, meaning the optic discs show chronic loss of nerve tissue.
Clinical signs
Typical findings include optic disc cupping, pallor, and visual field loss consistent with glaucoma. Clinical features vary; refer to documentation.
When to use this code
Use H47.233 when the provider documents glaucomatous optic atrophy affecting both optic nerves. It may support a diagnosis recorded after eye examination, imaging, or visual field testing. Code the bilateral condition only when both eyes are specifically documented.
Do not use for
Do not use this code for glaucoma without documented optic atrophy, or for unilateral disease. Check documentation if the record only states optic nerve changes without a clear glaucomatous cause.
Coding tip
Confirm that the provider links optic atrophy to glaucoma and states bilateral involvement before assigning H47.233.
