ICD-10 Code H47.23 – Glaucomatous optic atrophy (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H47.23 – Glaucomatous optic atrophy
What it is
H47.23 identifies optic nerve damage caused by glaucoma. Use it when the record documents glaucomatous optic atrophy, meaning the optic disc has been damaged from chronic glaucomatous disease.
Clinical signs
Typical findings include optic disc cupping, rim thinning, and corresponding visual field loss. Clinical features vary; refer to documentation for the specific eye findings supporting the diagnosis.
When to use this code
Use this code when the provider documents glaucomatous optic atrophy or optic nerve atrophy due to glaucoma. It may appear in assessments, problem lists, or ophthalmology notes describing established glaucomatous damage. Code it only when the condition is explicitly stated, not when glaucoma is merely suspected.
Do not use for
Do not use it for glaucoma without optic atrophy, optic atrophy from another cause, or nonspecific visual loss. Check documentation if the note does not clearly link the optic nerve damage to glaucoma.
Coding tip
Confirm the provider links the optic atrophy to glaucoma before assigning H47.23.
