ICD-10 Code H53.029 – Refractive amblyopia, unspecified eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H53.029 – Refractive amblyopia, unspecified eye
What it is
Use this code for amblyopia caused by unequal or uncorrected refractive error, where the affected eye is not specified. It describes reduced visual development from blurred retinal images rather than a structural eye disease.
Clinical signs
Typical findings include decreased visual acuity in one or both eyes that does not fully improve with standard correction. Clinical features vary; refer to documentation.
When to use this code
Assign H53.029 when the provider documents refractive amblyopia but does not identify the eye involved. Use it for charted diagnoses based on eye exam findings, vision testing, or ophthalmology assessment. If the record specifies laterality, choose the more specific code.
Do not use for
Do not use this code for amblyopia from strabismus, deprivation, or other non-refractive causes. Do not use it when the documentation clearly identifies the right or left eye.
Coding tip
Check the assessment for laterality and the cause of amblyopia before coding.
