ICD-10 Code H53.023 – Refractive amblyopia, bilateral (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H53.023 – Refractive amblyopia, bilateral
What it is
H53.023 identifies reduced vision in both eyes caused by unequal or uncorrected refractive error during visual development. The brain does not learn to use clear images from either eye properly.
Clinical signs
Common findings include decreased visual acuity in both eyes and poor improvement with standard correction. Clinical features vary; refer to documentation for laterality, refractive error, and amblyopia confirmation.
When to use this code
Use this code when the record documents bilateral amblyopia due to refractive error, not just blurred vision or myopia. It fits pediatric or other developmental cases where both eyes are affected. Code the condition only when the provider links the vision loss to refractive amblyopia.
Do not use for
Do not use it for unilateral amblyopia, unspecified amblyopia, or refractive error without amblyopia. Check documentation if the note only states decreased vision or needs glasses.
Coding tip
Confirm that the provider explicitly documents bilateral refractive amblyopia before assigning H53.023.
