ICD-10 Code H47.299 – Other optic atrophy, unspecified eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H47.299 – Other optic atrophy, unspecified eye
What it is
This code identifies optic nerve atrophy in an unspecified eye when the record does not name the right or left eye. It is used for a documented optic nerve wasting process that is not otherwise classified.
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 H47.299 when the provider documents other optic atrophy but does not specify the affected eye. It also fits cases where the note confirms optic nerve atrophy without further detail. If laterality is stated elsewhere in the record, code the specified eye instead.
Do not use for
Do not use this code for optic atrophy with a documented right or left eye, or when the diagnosis is a different optic nerve disorder. Check documentation.
Coding tip
Verify whether the note or imaging report identifies laterality before assigning the unspecified-eye code.
