ICD-10 Code H47.631 – Disorders of Visual Cortex in (Due to) Neoplasm, Right Side of Brain (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H47.631 – Disorders of visual cortex in (due to) neoplasm, right side of brain
What it is
This code identifies a visual cortex disorder caused by a neoplasm affecting the right side of the brain. Use it when the chart links the visual problem to a tumor or tumor-related mass effect in the right cerebral hemisphere.
Clinical signs
Clinical features vary; refer to documentation. Typical findings may include visual field loss, impaired visual processing, or other cortical visual deficits associated with a right-sided brain lesion.
When to use this code
Use this code when the provider documents a disorder of the visual cortex due to a neoplasm on the right side of the brain. It may apply in confirmed primary or secondary brain tumors when the visual deficit is attributed to the lesion. If laterality or cause is unclear, check documentation before coding.
Do not use for
Do not use it for visual loss from eye disease, optic nerve disorders, or unspecified brain tumors without documented visual cortex involvement. Check documentation if the neoplasm is not stated as the cause.
Coding tip
Link the visual deficit to the right-sided neoplasm in the provider note before assigning H47.631.
