ICD-10 Code H47.62 – Disorders of Visual Cortex in (Due to) Inflammatory Disorders (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H47.62 – Disorders of visual cortex in (due to) inflammatory disorders
What it is
This code identifies visual cortex dysfunction caused by an inflammatory disorder affecting the brain. Use it when the problem is centered in the occipital visual pathways rather than the eye itself.
Clinical signs
Clinical features vary; refer to documentation. Commonly noted findings include visual field loss, reduced visual perception, or cortical visual impairment with a neurologic inflammatory cause.
When to use this code
Use H47.62 when the provider documents a disorder of the visual cortex due to inflammation, such as inflammatory involvement of the central nervous system. Code it when the record links the visual deficit to the cortical lesion, not to refractive, retinal, or optic nerve disease.
Do not use for
Do not use this code for visual loss from eye disorders, optic nerve disease, or unspecified vision problems. Check documentation if the inflammatory cause or cortical location is not clearly stated.
Coding tip
Look for documentation that ties the visual disturbance to an inflammatory cortical process before assigning H47.62.
