ICD-10 Code H53.489 – Generalized Contraction of Visual Field, Unspecified Eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H53.489 – Generalized contraction of visual field, unspecified eye
What it is
H53.489 identifies a generalized narrowing of the visual field in an unspecified eye. Use it when documentation describes overall field loss or “tunnel vision” without naming a more specific cause.
Clinical signs
Typical findings include reduced peripheral vision on visual field testing and complaints of difficulty seeing to the sides. Clinical features vary; refer to documentation.
When to use this code
Use this code when the record states generalized contraction of the visual field and does not specify the affected eye. It also fits cases where the clinician documents field constriction but gives no underlying diagnosis. If the note identifies a cause, code that condition instead when instructed.
Do not use for
Do not use it for normal visual field findings, isolated central vision loss, or a clearly documented specific eye disorder. Check documentation if the narrowing is part of another diagnosed disease process.
Coding tip
Confirm whether the chart identifies one eye, both eyes, or a more specific disorder before assigning H53.489.
