ICD-10 Code H47.532 – Disorders of visual pathways in (due to) vascular disorders, left side (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H47.532 – Disorders of visual pathways in (due to) vascular disorders, left side
What it is
H47.532 identifies a disorder of the visual pathways on the left side caused by a vascular condition. Use it when the documented problem involves optic or visual pathway dysfunction linked to impaired blood flow or vascular disease.
Clinical signs
Clinical features vary; refer to documentation. Commonly reported findings may include unilateral visual loss, field defects, or other left-sided visual pathway abnormalities attributed to a vascular cause.
When to use this code
Use this code when the provider documents a left-sided visual pathway disorder due to vascular disease, such as ischemic injury affecting the optic pathway. It may also apply when the record clearly links the visual abnormality to a vascular etiology. Check documentation for laterality and cause before assigning the code.
Do not use for
Do not use this code for nonspecific visual complaints without a documented vascular cause. Avoid it when the problem is bilateral, unspecified, or better described by another eye or neurologic diagnosis.
Coding tip
Verify both the left-sided location and the vascular cause in the provider’s note before coding H47.532.
