ICD-10 Code H53.013 – Deprivation amblyopia, bilateral (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H53.013 – Deprivation amblyopia, bilateral
What it is
Use this code for bilateral amblyopia caused by visual deprivation, where normal visual development is interrupted by a cloudy or blocked visual pathway in both eyes. It reflects reduced vision from lack of clear retinal image formation.
Clinical signs
Typical findings include decreased visual acuity in both eyes and a history of bilateral media opacity, ptosis, or other obstruction affecting vision during development. Clinical features vary; refer to documentation.
When to use this code
Assign H53.013 when the record documents deprivation amblyopia affecting both eyes, such as from bilateral congenital cataracts or other bilateral obstruction. Use it only when the provider identifies amblyopia as deprivation-related, not merely reduced vision. Check documentation if the cause is unclear.
Do not use for
Do not use this code for unilateral deprivation amblyopia, other amblyopia types, or vision loss without documented amblyopia. Avoid it when the chart only notes cataract, ptosis, or refractive error without the diagnosis.
Coding tip
Code the amblyopia diagnosis only when the provider links it to deprivation and specifies bilateral involvement.
