ICD-10 Code H47.6 – Disorders of visual cortex (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H47.6 – Disorders of visual cortex
What it is
H47.6 identifies disorders affecting the visual cortex, the brain area that processes visual information. Use it when documentation indicates cortical visual dysfunction rather than an eye disease.
Clinical signs
Clinical features vary; refer to documentation. Findings may include impaired visual perception, visual field abnormalities, or difficulty recognizing objects despite preserved eye structures.
When to use this code
Use H47.6 when the provider documents a disorder of the visual cortex, cortical blindness, or similar central visual processing impairment. Code it when the problem is neurologic and not explained by primary ocular pathology. Check documentation for laterality and associated neurologic conditions if recorded.
Do not use for
Do not use this code for refractive errors, retinal disease, or optic nerve disorders. If the record does not clearly identify cortical involvement, check documentation before assigning H47.6.
Coding tip
Look for wording such as “visual cortex,” “cortical blindness,” or “central visual processing” in the assessment before coding.
