ICD-10 Code H53.001 – Unspecified amblyopia, right eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H53.001 – Unspecified amblyopia, right eye
What it is
H53.001 identifies amblyopia affecting the right eye when the type is not further specified. It means reduced visual function in that eye that is not explained by a structural eye disease alone.
Clinical signs
Clinical features may include decreased visual acuity in the right eye, poor visual development, or reduced binocular vision. Clinical features vary; refer to documentation.
When to use this code
Use this code when the provider documents amblyopia of the right eye but does not specify the subtype, such as strabismic, refractive, or deprivation amblyopia. It is also appropriate when the record clearly states unspecified amblyopia limited to the right eye. Check documentation if laterality or type is unclear.
Do not use for
Do not use H53.001 when the amblyopia type is documented more specifically, or when the condition involves both eyes or the left eye. Do not use it for general visual loss without a diagnosis of amblyopia.
Coding tip
Code the laterality exactly as documented, and query the provider if the eye or amblyopia type is missing.
