Deprivation amblyopia, bilateral

This code describes a type of amblyopia affecting both eyes, caused by a significant visual deprivation during the critical period of visual development. This deprivation prevents the brain from properly processing visual input from both eyes, leading to reduced visual acuity that cannot be corrected by refractive means.

Use this code when documentation clearly indicates bilateral amblyopia resulting from conditions such as congenital cataracts, severe ptosis, or prolonged patching that obstructed vision in both eyes during infancy or early childhood. The physician's assessment should confirm the deprivation as the underlying cause and specify bilateral involvement.

• Ensure the documentation explicitly states "bilateral" involvement; otherwise, a unilateral code may be more appropriate.
• Distinguish from other types of amblyopia, such as strabismic or refractive, which have different ICD-10-CM codes.
• Code any underlying conditions causing the deprivation (e.g., congenital cataract) in addition to this amblyopia code.
