ICD-10 Code H47.232 – Glaucomatous optic atrophy, left eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H47.232 – Glaucomatous optic atrophy, left eye
What it is
H47.232 identifies optic nerve damage in the left eye caused by glaucoma. Use it when documentation states glaucomatous optic atrophy, reflecting characteristic loss of optic nerve tissue.
Clinical signs
Findings may include optic disc cupping, rim thinning, and corresponding visual field loss in the left eye. Clinical features vary; refer to documentation.
When to use this code
Use this code when the provider documents glaucomatous optic atrophy specifically affecting the left eye. It is appropriate when the record links optic nerve atrophy to glaucoma rather than to another optic neuropathy. If laterality is unclear, check documentation before coding.
Do not use for
Do not use it for glaucoma without documented optic atrophy, or for optic atrophy from non-glaucomatous causes. Check documentation if the condition is bilateral or the eye is not specified.
Coding tip
Confirm both the glaucomatous cause and left-eye laterality in the provider note before assigning H47.232.
