ICD-10 Code H47.219 – Primary optic atrophy, unspecified eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H47.219 – Primary optic atrophy, unspecified eye
What it is
H47.219 identifies primary optic atrophy affecting an unspecified eye. It means the optic nerve has lost function and appears pale, without a documented cause or laterality in the record.
Clinical signs
Typical findings include reduced visual acuity, color vision loss, and optic disc pallor on eye examination. Visual field defects may be present; clinical features vary, so refer to documentation.
When to use this code
Use this code when the provider documents primary optic atrophy but does not specify the affected eye. It also fits when the note confirms optic nerve atrophy without an identified underlying cause. If laterality is documented, choose the more specific code instead.
Do not use for
Do not use this code for optic atrophy with a documented cause, such as glaucoma, ischemia, or trauma. Check documentation if the record identifies a different optic nerve disorder or specifies right, left, or bilateral involvement.
Coding tip
Verify that “primary” optic atrophy is explicitly documented before assigning H47.219.
