ICD-10 Code H47.519 – Disorders of Visual Pathways in (Due to) Inflammatory Disorders, Unspecified Side (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H47.519 – Disorders of visual pathways in (due to) inflammatory disorders, unspecified side
What it is
Use this code for a disorder affecting the visual pathways that is caused by an inflammatory condition, when the affected side is not documented. It identifies the neurologic eye-related complication rather than the underlying inflammatory disease.
Clinical signs
Clinical features vary; refer to documentation. Common findings may include decreased visual acuity, visual field loss, or other visual pathway abnormalities linked to inflammation.
When to use this code
Use H47.519 when the provider documents a visual pathway disorder due to inflammation and does not specify right or left side. This is appropriate when the record supports an inflammatory cause, such as optic pathway involvement, but laterality is absent. Code the underlying inflammatory condition separately when instructed by the record and coding guidelines.
Do not use for
Do not use this code for unspecified visual loss without a documented inflammatory cause. Also avoid it when the side is documented, because a laterality-specific code may be more accurate.
Coding tip
Check the note for laterality and the named inflammatory diagnosis before assigning H47.519.
