Leucocoria, right eye

This code signifies the presence of a white pupillary reflex in the right eye. Leucocoria is a non-specific sign that can indicate various underlying ocular pathologies, particularly those affecting the posterior segment of the eye.

Apply this code when documentation explicitly states "leucocoria, right eye" or describes a white reflex observed in the right pupil. This often occurs during pediatric eye examinations or when a parent reports a "cat's eye reflex" in their child.

• Always specify laterality (right, left, bilateral, or unspecified) when documented.
• Leucocoria is a symptom, not a diagnosis; code the underlying definitive diagnosis if known and documented (e.g., retinoblastoma, cataract, Coats' disease).
• If the underlying cause is unknown or not yet diagnosed, this code can be used as a primary diagnosis.
