ICD-10 Code H53.012 – Deprivation amblyopia, left eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H53.012 – Deprivation amblyopia, left eye
What it is
H53.012 identifies amblyopia caused by visual deprivation in the left eye. The left eye has reduced visual development because something blocked clear vision during the critical period.
Clinical signs
Findings usually include decreased visual acuity in the left eye that is not fully explained by refractive error alone. Clinical features vary; refer to documentation.
When to use this code
Use this code when the record states deprivation amblyopia affecting the left eye, such as from congenital cataract, ptosis, or another documented obstruction to vision. Code it only when the provider links the amblyopia to the left eye. Check documentation if laterality is unclear.
Do not use for
Do not use this code for amblyopia of the right eye, bilateral amblyopia, or unspecified amblyopia. Do not assign it when the chart only notes decreased vision without a documented deprivation cause.
Coding tip
Verify both laterality and the deprivation cause in the note before assigning H53.012.
