ICD-10 Code H44.539 – Leucocoria, unspecified eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H44.539 – Leucocoria, unspecified eye
What it is
Leucocoria means a white pupillary reflex, often seen when light reflects abnormally from the eye. This code identifies leucocoria when the affected eye is not specified in the documentation.
Clinical signs
Typical findings include a white or yellow-white pupil reflex on examination, sometimes noted in photographs or indirect ophthalmoscopy. Clinical features vary; refer to documentation.
When to use this code
Use H44.539 when the record documents leucocoria but does not identify the right or left eye. It may be used for initial evaluation, follow-up notes, or referrals when the provider has not specified laterality. Confirm that the documentation supports leucocoria rather than another ocular abnormality.
Do not use for
Do not use this code if the chart identifies the right or left eye, or if another diagnosis better explains the white reflex. Check documentation for a more specific ocular disorder.
Coding tip
If laterality appears anywhere in the note, select the more specific code instead of unspecified H44.539.
