ICD-10 Code H53.459 – Other localized visual field defect, unspecified eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H53.459 – Other localized visual field defect, unspecified eye
What it is
H53.459 identifies a localized defect in the visual field affecting an unspecified eye. Use it when documentation describes a limited area of vision loss or missing field without naming the eye.
Clinical signs
Findings may include a scotoma, sector defect, or other focal field loss on formal visual field testing. Clinical features vary; refer to documentation.
When to use this code
Use this code when the clinician documents a localized visual field defect but does not specify right or left eye. It also fits charted diagnoses that describe a focal field deficit without a more precise cause. Confirm that the record supports a field defect, not reduced visual acuity.
Do not use for
Do not use it for generalized vision loss, blurry vision, or refractive error. If the eye is specified or a more exact visual field diagnosis is documented, code that instead.
Coding tip
Check whether the note identifies the eye or a specific field pattern before defaulting to unspecified eye.
