ICD-10 Code H47.292 – Other optic atrophy, left eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H47.292 – Other optic atrophy, left eye
What it is
H47.292 identifies optic nerve atrophy affecting the left eye when the record does not specify a more exact type. It means the optic nerve has lost function or appearance consistent with wasting.
Clinical signs
Typical findings include decreased visual acuity, reduced color vision, and optic disc pallor on eye examination. Clinical features vary; refer to documentation.
When to use this code
Use this code when the clinician documents other optic atrophy limited to the left eye and no more specific optic nerve diagnosis is stated. It is appropriate for confirmed optic nerve atrophy, not for vague visual complaints alone. If the note names a different laterality or a more specific cause, code that instead.
Do not use for
Do not use this code for bilateral optic atrophy, unspecified optic atrophy, or optic neuritis. Check documentation if the record does not clearly identify the left eye.
Coding tip
Verify laterality and the exact wording “other optic atrophy” before assigning H47.292.
