Leucocoria, left eye

This code describes the presence of leucocoria, specifically in the left eye. Leucocoria, also known as a "white pupil," is an abnormal white reflection from the retina of the eye, often observed during an ophthalmic examination. It is a sign of various underlying ocular pathologies.

Use this code when documentation clearly indicates the presence of leucocoria affecting the patient's left eye. This often occurs during pediatric eye exams or when a parent reports a white reflex in a child's pupil. Supporting documentation would include ophthalmologist notes detailing the observation of a white pupillary reflex in the left eye.

• Always specify laterality (left, right, or bilateral) when documenting and coding leucocoria.
• Leucocoria is a symptom, not a diagnosis; always code the underlying cause if known (e.g., retinoblastoma, cataract, Coats' disease).
• Do not confuse with other pupillary abnormalities like anisocoria or miosis/mydriasis, which have distinct codes.
