ICD-10 Code H53.002 – Unspecified amblyopia, left eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H53.002 – Unspecified amblyopia, left eye
What it is
H53.002 identifies amblyopia affecting the left eye when the type is not specified. It means reduced visual acuity in that eye that is not fully explained by a structural eye problem.
Clinical signs
Typical findings include decreased vision in the left eye, often with reduced best-corrected acuity compared with the other eye. Clinical features vary; refer to documentation.
When to use this code
Use this code when the record states amblyopia in the left eye but does not document the subtype, such as strabismic, refractive, or deprivation amblyopia. It also fits when the provider documents amblyopia without further detail and laterality is clearly left. Check documentation if the cause or type is specified elsewhere.
Do not use for
Do not use H53.002 if the chart identifies a specific amblyopia type or a different eye. Do not use it for general blurred vision or other visual disturbance without a documented diagnosis of amblyopia.
Coding tip
Verify laterality and whether the provider documented a specific amblyopia subtype before selecting the unspecified code.
