ICD-10 Code H47.539 – Disorders of Visual Pathways in (Due to) Vascular Disorders, Unspecified Side (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H47.539 – Disorders of visual pathways in (due to) vascular disorders, unspecified side
What it is
This code identifies a disorder of the visual pathways caused by a vascular condition, when the affected side is not specified. Use it for documented vascular injury or impairment involving the optic pathways.
Clinical signs
Clinical features vary; refer to documentation. Typical findings may include vision loss, visual field defects, or other neurologic visual disturbances linked to a vascular event affecting the visual pathway.
When to use this code
Use H47.539 when the provider documents a vascular disorder affecting the visual pathways and does not specify left or right side. It may apply after evaluation of stroke-related or ischemic visual pathway involvement. Check documentation for laterality and the exact vascular cause before assigning this code.
Do not use for
Do not use this code if the visual problem is from a nonvascular cause, such as trauma, infection, or a primary eye disease. Also avoid it when documentation identifies a specific side or a more precise diagnosis.
Coding tip
Confirm both the vascular etiology and the unspecified laterality in the record before coding.
