ICD-10 Code H26.03 – Infantile and Juvenile Nuclear Cataract (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H26.03 – Infantile and juvenile nuclear cataract
What it is
H26.03 identifies a nuclear cataract that develops in infancy or childhood. It refers to lens opacity centered in the nucleus, affecting visual clarity in a young patient.
Clinical signs
Findings may include decreased visual acuity, abnormal red reflex, or visible lens opacity on eye examination. Clinical features vary; refer to documentation.
When to use this code
Use this code when the record clearly states infantile or juvenile nuclear cataract, or when the ophthalmologist documents nuclear cataract in a child. Apply it for confirmed diagnosis, not for nonspecific blurred vision alone.
If the note only says cataract without age or type, check documentation before coding. Confirm laterality and any associated ocular conditions separately when documented.
Do not use for
Do not use H26.03 for age-related cataract, traumatic cataract, or congenital cataract unless the provider specifically documents infantile or juvenile nuclear cataract. Check documentation.
Coding tip
Code from the ophthalmology assessment, and verify that both the age group and nuclear type are explicitly documented.
