ICD-10 Code H53.03 – Strabismic amblyopia (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H53.03 – Strabismic amblyopia
What it is
Strabismic amblyopia is reduced vision in one eye caused by a misalignment of the eyes. The brain favors one eye and suppresses the other, leading to poor visual development.
Clinical signs
Typical findings include decreased visual acuity in the affected eye and a history or exam showing strabismus. Clinical features vary; refer to documentation.
When to use this code
Use this code when the provider documents amblyopia specifically attributed to strabismus. It fits cases where the visual deficit is linked to eye misalignment rather than refractive error or deprivation. If the record does not clearly state the cause, check documentation.
Do not use for
Do not use this code for amblyopia from anisometropia, deprivation, or unspecified amblyopia. Also avoid it when strabismus is present but amblyopia is not documented.
Coding tip
Confirm that the chart names strabismic amblyopia, not just strabismus, before assigning H53.03.
