ICD-10 Code H47.291 – Other optic atrophy, right eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H47.291 – Other optic atrophy, right eye
What it is
This code identifies optic nerve atrophy affecting the right eye when the documentation does not specify a more exact type. It indicates loss or thinning of optic nerve tissue, which can reduce visual function.
Clinical signs
Findings may include decreased visual acuity, visual field loss, or a pale optic disc on examination. Clinical features vary; refer to documentation.
When to use this code
Use H47.291 when the provider documents other optic atrophy in the right eye and no more specific optic neuropathy or atrophy type is stated. It is appropriate for confirmed unilateral right-eye involvement. Do not assume laterality if the record is unclear; check documentation.
Do not use for
Do not use this code for unspecified optic atrophy, left eye, or bilateral optic atrophy. Also avoid it when the chart identifies a different optic nerve disorder or a more specific cause.
Coding tip
Verify laterality and the exact wording in the assessment before assigning H47.291.
