ICD-10 Code H47.529 – Disorders of Visual Pathways in (Due to) Neoplasm, Unspecified Side (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H47.529 – Disorders of visual pathways in (due to) neoplasm, unspecified side
What it is
This code identifies a disorder affecting the visual pathways caused by a neoplasm, when the affected side is not specified. Use it when the record links the visual pathway problem to a tumor but does not name left or right.
Clinical signs
Clinical features vary; refer to documentation. Common findings may include visual field loss, reduced visual acuity, or other neurologic visual deficits related to optic pathway involvement.
When to use this code
Use this code when the provider documents a visual pathway disorder due to a neoplasm and laterality is not stated. It fits cases where imaging, exam, or consultation notes tie the visual abnormality to tumor involvement. If the record identifies a specific side, code the laterality instead.
Do not use for
Do not use this code for visual problems without a documented neoplastic cause. Also avoid it when the affected side is clearly documented and a laterality-specific code is available.
Coding tip
Check documentation for the tumor type, site, and laterality before assigning H47.529.
