ICD-10 Code H47.621 – Disorders of Visual Cortex in (Due to) Inflammatory Disorders, Right Side of Brain (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H47.621 – Disorders of visual cortex in (due to) inflammatory disorders, right side of brain
What it is
This code identifies a visual cortex disorder caused by an inflammatory condition affecting the right side of the brain. Use it when documentation links the visual disturbance to right-sided cerebral inflammation.
Clinical signs
Clinical features vary; refer to documentation. Findings may include visual processing problems, such as difficulty interpreting what is seen, with evidence that the cause is inflammatory and localized to the right cerebral hemisphere.
When to use this code
Use this code when the provider documents a disorder of the visual cortex due to inflammation, and specifies the right side of the brain. It is appropriate when the visual abnormality is secondary to a confirmed inflammatory neurologic process. If laterality or inflammatory cause is not stated, check documentation.
Do not use for
Do not use this code for nonspecific visual loss, eye disease, or visual symptoms without a documented cortical and inflammatory cause. If the record does not confirm right-sided involvement, check documentation.
Coding tip
Code only when the record clearly links the visual cortex disorder to right-sided inflammatory brain disease.
