ICD-10 Code H47.622 – Disorders of Visual Cortex in (Due to) Inflammatory Disorders, Left Side of Brain (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H47.622 – Disorders of visual cortex in (due to) inflammatory disorders, left side of brain
What it is
This code identifies a visual cortex disorder caused by an inflammatory condition affecting the left side of the brain. Use it when documentation links visual processing problems to a left-sided inflammatory brain disorder.
Clinical signs
Clinical features vary; refer to documentation. Findings may include visual field loss, impaired visual interpretation, or other cortical visual deficits attributed to left hemispheric inflammation.
When to use this code
Use this code when the provider clearly documents a disorder of the visual cortex due to inflammation on the left side of the brain. It is appropriate when the neurologic or ophthalmic note ties the visual deficit to that specific cause and location. If the cause or side is not stated, check documentation.
Do not use for
Do not use this code for nonspecific vision loss, retinal disease, optic nerve disorders, or visual problems without documented cortical involvement. Do not assign it when the inflammatory cause or left-sided brain involvement is not documented.
Coding tip
Match both the anatomic site and the inflammatory cause in the chart before assigning H47.622.
