ICD-10 Code H53.01 – Deprivation amblyopia (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H53.01 – Deprivation amblyopia
What it is
Deprivation amblyopia is reduced vision that develops when the eye is not getting a clear image during early visual development. It is usually linked to an obstruction or other condition that blocks normal sight in one or both eyes.
Clinical signs
Clinical features vary; refer to documentation. Common findings include decreased visual acuity, poor fixation, and reduced vision not fully explained by refractive error alone. The underlying cause may be cataract, corneal opacity, ptosis, or another visual deprivation source.
When to use this code
Use this code when the record identifies amblyopia caused by visual deprivation rather than strabismus or anisometropia. It fits cases where the clinician documents loss of visual development from an opaque lens, droopy lid, or similar barrier to vision. Check documentation if the cause is not stated clearly.
Do not use for
Do not use this code for amblyopia due to strabismus or unequal refractive error. If the note describes only decreased vision without a documented deprivation cause, verify the diagnosis before assigning H53.01.
Coding tip
Code the deprivation cause separately when documented, and confirm that the record supports amblyopia rather than another vision disorder.
