ICD-10 Code H47.239 – Glaucomatous optic atrophy, unspecified eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H47.239 – Glaucomatous optic atrophy, unspecified eye
What it is
This code identifies optic nerve damage from glaucoma when the eye is not specified. It describes glaucomatous optic atrophy, meaning the optic disc shows loss or thinning related to chronic glaucomatous injury.
Clinical signs
Typical findings include optic nerve cupping, pallor, and visual field loss consistent with glaucoma. Clinical features vary; refer to documentation.
When to use this code
Use this code when the record documents glaucomatous optic atrophy but does not identify the right, left, or bilateral eye. It is appropriate when the clinician links optic nerve atrophy to glaucoma and laterality is missing or not stated. Check documentation if the note is unclear.
Do not use for
Do not use this code for optic atrophy from non-glaucomatous causes or for suspected glaucoma without documented optic atrophy. Do not assign it when laterality is clearly documented and a more specific code is available.
Coding tip
Confirm that the provider explicitly documents glaucomatous optic atrophy and that eye laterality is unspecified before coding H47.239.
