ICD-10 Code H47.032 – Optic nerve hypoplasia, left eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H47.032 – Optic nerve hypoplasia, left eye
What it is
H47.032 identifies underdevelopment of the optic nerve in the left eye. This congenital or early-life condition can limit visual signal transmission from that eye.
Clinical signs
Findings may include reduced vision, a small optic disc, and abnormal optic nerve appearance on eye examination. Clinical features vary; refer to documentation.
When to use this code
Use this code when the provider documents optic nerve hypoplasia specifically in the left eye. It fits ophthalmology or pediatric records that clearly identify unilateral involvement. If laterality is not stated, check documentation before assigning a code.
Do not use for
Do not use it for optic nerve disorders without hypoplasia or for right-eye or bilateral cases. If the record only says “optic nerve abnormality,” check documentation.
Coding tip
Always confirm laterality in the assessment or problem list before coding H47.032.
