ICD-10 Code H47.611 – Cortical blindness, right side of brain (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H47.611 – Cortical blindness, right side of brain
What it is
H47.611 identifies cortical blindness caused by damage to the right side of the brain, usually the visual cortex or related pathways. Vision loss is neurologic, not due to an eye disease.
Clinical signs
Patients may have absent or severely reduced vision with normal or near-normal eye examination findings. Clinical features vary; refer to documentation for laterality, extent of vision loss, and associated neurologic deficits.
When to use this code
Use this code when the provider documents cortical blindness affecting the right side of the brain. It may apply after stroke, trauma, or other brain injury if the record clearly links the blindness to right cerebral cortical damage. Code only when laterality is documented.
Do not use for
Do not use this code for blindness from retinal, optic nerve, or other ocular causes. If the record does not specify the right side of the brain, check documentation before assigning H47.611.
Coding tip
Verify that the note distinguishes cortical blindness from eye disease and includes right-sided brain involvement before coding.
