ICD-10 Code H47 – Other disorders of optic [2nd] nerve and visual pathways (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H47 – Other disorders of optic [2nd] nerve and visual pathways
What it is
H47 covers disorders affecting the optic nerve or visual pathways that are not classified elsewhere. Use it when the record identifies a nonspecific or other optic pathway problem without a more precise diagnosis.
Clinical signs
Clinical features vary; refer to documentation. Findings may include decreased vision, visual field defects, or abnormal optic nerve examination, but the exact presentation depends on the underlying disorder.
When to use this code
Use H47 when the clinician documents an “other” disorder of the optic nerve or visual pathways and no more specific ICD-10-CM code applies. It is also appropriate when the note confirms optic pathway involvement but does not identify a separate, coded condition. Check documentation for laterality and specificity if available.
Do not use for
Do not use this code for clearly specified optic nerve diseases that have their own ICD-10-CM code, or for visual symptoms alone without a documented disorder. If the condition is better described elsewhere, code that diagnosis instead.
Coding tip
Before assigning H47, look for a more specific optic nerve or visual pathway diagnosis in the chart.
