ICD-10 Code H47.211 – Primary optic atrophy, right eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H47.211 – Primary optic atrophy, right eye
What it is
H47.211 identifies primary optic atrophy in the right eye. It means the optic nerve has lost function and shows degeneration without a documented underlying cause.
Clinical signs
Typical findings include decreased 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 record specifically documents primary optic atrophy affecting the right eye. It is appropriate when the provider identifies optic nerve atrophy and laterality is clearly right-sided. Check documentation if the cause, laterality, or acuity is unclear.
Do not use for
Do not use this code for optic atrophy with a documented underlying cause, such as inflammation, glaucoma, or trauma. Do not use it when the left eye, both eyes, or unspecified eye is recorded.
Coding tip
Confirm that “primary” and “right eye” are both documented before assigning H47.211.
