ICD-10 Code H53.48 – Generalized contraction of visual field (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H53.48 – Generalized contraction of visual field
What it is
H53.48 identifies a generalized narrowing of the visual field, meaning the patient sees less than normal in all directions. Use it when documentation describes diffuse peripheral field loss rather than a localized defect.
Clinical signs
Patients may report tunnel vision, bumping into objects, or difficulty seeing in the periphery. Clinical features vary; refer to documentation and visual field testing when available.
When to use this code
Use this code when the record specifically states generalized contraction of the visual field, concentric field loss, or similar wording. It may support coding after ophthalmology evaluation or formal perimetry. Do not assume the cause from the field defect alone; code the documented underlying condition separately if reported.
Do not use for
Do not use H53.48 for a localized blind spot, hemianopia, or other named field defects unless the provider documents generalized contraction. Check documentation if the chart only notes blurred vision or reduced acuity.
Coding tip
Match the code to the exact visual field wording and avoid upgrading a partial defect to generalized contraction.
