ICD-10 Code H53.019 – Deprivation amblyopia, unspecified eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H53.019 – Deprivation amblyopia, unspecified eye
What it is
H53.019 identifies deprivation amblyopia in an unspecified eye, meaning reduced visual development caused by blocked or limited visual input. Use it when the record documents amblyopia from obstruction or deprivation but does not specify the eye.
Clinical signs
Typical findings include decreased visual acuity in the affected eye, often with a history of cataract, ptosis, corneal opacity, or another visual obstruction. Clinical features vary; refer to documentation.
When to use this code
Use this code when the clinician documents deprivation amblyopia and does not identify the right or left eye. It also fits cases where the cause is recorded as reduced visual stimulus from an obstructive condition. If the eye is specified, choose the laterality-specific code instead.
Do not use for
Do not use H53.019 for refractive amblyopia, strabismic amblyopia, or nonspecific blurred vision. Check documentation if the note describes another amblyopia type or identifies a different eye.
Coding tip
Confirm both the amblyopia type and laterality in the ophthalmology note before assigning this unspecified-eye code.
