ICD-10 Code H47.522 – Disorders of Visual Pathways in (Due to) Neoplasm, Left Side (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H47.522 – Disorders of visual pathways in (due to) neoplasm, left side
What it is
H47.522 identifies a disorder of the left visual pathways caused by a neoplasm. Use it when a tumor is documented as affecting visual pathway structures on the left side.
Clinical signs
Findings may include visual field loss, reduced visual acuity, or other neuro-ophthalmic deficits linked to the left visual pathway. Clinical features vary; refer to documentation.
When to use this code
Use this code when the provider documents a neoplasm causing a left-sided visual pathway disorder, such as optic tract, chiasmal, or post-chiasmal involvement. It applies when the record clearly links the visual pathway abnormality to the tumor. Check documentation if laterality or cause is unclear.
Do not use for
Do not use this code for unspecified visual loss, benign eye complaints, or visual pathway disorders without a documented neoplasm cause. Do not assign it if the side is not documented.
Coding tip
Confirm both the neoplasm association and left-sided laterality in the clinical note before assigning H47.522.
