ICD-10 Code H47.512 – Disorders of visual pathways in (due to) inflammatory disorders, left side (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H47.512 – Disorders of visual pathways in (due to) inflammatory disorders, left side
What it is
H47.512 identifies a disorder of the visual pathways on the left side caused by inflammation. Use it when the record links the visual pathway problem to an inflammatory condition affecting that side.
Clinical signs
Clinical features vary; refer to documentation. You may see left-sided visual pathway dysfunction with visual field loss, reduced visual processing, or other neurologic visual deficits described by the clinician.
When to use this code
Use this code when the provider documents an inflammatory disorder affecting the left visual pathways, such as optic pathway involvement or related neuro-ophthalmic inflammation. It is appropriate only when laterality and inflammatory cause are clearly stated. If the note is nonspecific, check documentation.
Do not use for
Do not use it for unspecified visual loss, noninflammatory eye disease, or visual pathway disorders without documented left-sided involvement. Check documentation if the cause or side is unclear.
Coding tip
Match both the inflammatory etiology and left laterality exactly as documented before assigning H47.512.
