ICD-10 Code H47.213 – Primary optic atrophy, bilateral (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H47.213 – Primary optic atrophy, bilateral
What it is
H47.213 identifies primary optic atrophy affecting both eyes. It describes optic nerve damage with loss of nerve tissue, not caused by another eye disease or injury.
Clinical signs
Typical findings include reduced visual acuity, visual field loss, and a pale optic disc on examination. Clinical features vary; refer to documentation.
When to use this code
Use this code when the provider documents bilateral primary optic atrophy or bilateral optic nerve pallor without an identified underlying cause. It may also fit follow-up visits when the diagnosis remains active and documented. Check documentation if the record suggests a secondary cause instead.
Do not use for
Do not use this code for optic atrophy due to glaucoma, optic neuritis, ischemia, trauma, or another documented disorder. Those cases require the underlying condition to be coded instead.
Coding tip
Confirm that the note states “primary” and “bilateral”; laterality and cause are key to choosing H47.213 correctly.
