ICD-10 Code H47.092 – Other disorders of optic nerve, not elsewhere classified, left eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H47.092 – Other disorders of optic nerve, not elsewhere classified, left eye
What it is
This code identifies a disorder affecting the left optic nerve that does not fit a more specific diagnosis. Use it when documentation names an optic nerve abnormality in the left eye but gives no clearer category.
Clinical signs
Clinical features vary; refer to documentation. Commonly reported findings may include decreased visual acuity, visual field loss, or abnormal optic nerve examination findings affecting the left eye.
When to use this code
Use H47.092 when the provider documents an unspecified or other optic nerve disorder limited to the left eye. It is appropriate when the record supports optic nerve involvement but does not name a more specific condition. Check documentation if laterality or diagnosis is unclear.
Do not use for
Do not use this code for optic nerve disorders with a more specific diagnosis or for bilateral, right-eye, or unspecified laterality documentation. Avoid it when the record does not clearly identify the left eye.
Coding tip
Verify the provider’s laterality and wording carefully; if the note is nonspecific, query for clarification before assigning H47.092.
