ICD-10 Code H47.63 – Disorders of visual cortex in (due to) neoplasm (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H47.63 – Disorders of visual cortex in (due to) neoplasm
What it is
This code identifies visual cortex dysfunction caused by a neoplasm. Use it when a tumor affects the brain’s visual processing areas and produces visual pathway symptoms.
Clinical signs
Clinical features vary; refer to documentation. Common findings may include visual field loss, visual perceptual problems, or difficulty interpreting visual input when the occipital cortex is involved.
When to use this code
Use H47.63 when the record clearly links a visual cortex disorder to a neoplasm, such as a brain tumor causing cortical visual impairment. You should also use it when the provider documents visual cortex involvement due to mass effect or direct tumor extension. Check documentation if the cause is not explicitly stated.
Do not use for
Do not use this code for visual problems from eye disease, optic nerve disorders, or unspecified visual loss without cortical involvement. If the neoplasm is not documented as the cause, check documentation.
Coding tip
Link the visual cortex disorder to the neoplasm in the record before assigning H47.63.
