Leucocoria, bilateral

This code signifies the presence of a white pupillary reflex in both eyes. Leucocoria is a non-specific sign that indicates an underlying ocular pathology, often serious, which prevents the normal red reflex from being observed. It can be caused by various conditions affecting the posterior segment of the eye.

Use this code when documentation explicitly states bilateral leucocoria. This is typically observed during a fundoscopic examination or when a parent/guardian reports a white reflex in a child's eyes. Supporting documentation would include ophthalmology notes detailing the finding in both eyes.

• Always specify laterality when documented; if only one eye is affected, use the appropriate unilateral code.
• Leucocoria is a sign, not a diagnosis; always code the underlying definitive diagnosis if known and documented (e.g., retinoblastoma, cataract, retinal detachment).
• Sequence this code as a secondary diagnosis when the underlying cause is identified and coded as the primary diagnosis.
