Unspecified amblyopia, left eye

This code signifies a "lazy eye" in the left eye where the exact type of amblyopia (e.g., strabismic, refractive, deprivation) has not been determined or documented. It indicates reduced vision in the left eye due to abnormal visual development during childhood, without an identifiable organic cause.

Use this code when the medical record clearly states amblyopia affecting the left eye, but the specific underlying cause or type of amblyopia is not documented. This is appropriate for initial diagnoses where further investigation is pending or when the etiology remains unknown after evaluation.

• Avoid using this code if the specific type of amblyopia (e.g., strabismic, anisometropic) is known and documented; use a more specific code instead.
• Always specify laterality (left, right, bilateral) when documented.
• Query the provider for clarification if the type of amblyopia is suspected but not explicitly stated.
