ICD-10 Code H53.039 – Strabismic amblyopia, unspecified eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H53.039 – Strabismic amblyopia, unspecified eye
What it is
H53.039 identifies amblyopia caused by strabismus, with the affected eye not specified. Use it when reduced vision is due to eye misalignment and documentation does not name the right or left eye.
Clinical signs
Findings usually include decreased visual acuity in one eye, suppression of the image from that eye, and a history or exam showing strabismus. Clinical features vary; refer to documentation.
When to use this code
Use this code when the record states strabismic amblyopia but does not identify which eye is affected. It also fits when the provider documents amblyopia linked to strabismus and laterality is not recorded. Check documentation if the note distinguishes another amblyopia type.
Do not use for
Do not use H53.039 for amblyopia from anisometropia, deprivation, or unspecified reduced vision without a strabismic cause. Do not assign it if the affected eye is documented separately and a laterality-specific code is available.
Coding tip
Confirm both the cause and laterality in the ophthalmology note before selecting H53.039.
