ICD-10 Code H47.29 – Other optic atrophy (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H47.29 – Other optic atrophy
What it is
H47.29 identifies optic nerve atrophy that does not fit a more specific ICD-10 category. Use it when documentation states optic atrophy, but the cause or subtype is not further defined.
Clinical signs
Typical findings include reduced visual acuity, visual field loss, and a pale optic disc on eye examination. Clinical features vary; refer to documentation.
When to use this code
Use this code when the clinician documents other optic atrophy, optic nerve atrophy, or optic atrophy NOS without naming a more specific type. It may apply after prior optic nerve injury, disease, or unexplained optic nerve pallor when the record supports atrophy. Check documentation if the etiology is described elsewhere.
Do not use for
Do not use H47.29 when the record specifies a different optic nerve disorder or a more exact optic atrophy code. If the diagnosis is uncertain or only optic disc pallor is noted, check documentation before coding.
Coding tip
Code the documented cause separately when available, and use H47.29 only for the atrophy itself.
