ICD-10 Code H26.09 – Other infantile and juvenile cataract (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H26.09 – Other infantile and juvenile cataract
What it is
This code identifies a cataract developing in infancy or childhood that does not fit a more specific congenital or juvenile cataract category. It refers to lens opacity in a young patient that affects vision or is documented as clinically significant.
Clinical signs
Typical findings include decreased visual acuity, abnormal red reflex, leukocoria, or visual developmental delay. Clinical features vary; refer to documentation.
When to use this code
Use H26.09 when the clinician documents an infantile or juvenile cataract and no more specific cataract type is named. It is appropriate for unilateral or bilateral cases if the record supports this diagnosis. Check documentation when the chart only says “cataract” without age-related detail.
Do not use for
Do not use this code for age-related cataract, traumatic cataract, or cataract due to another documented cause. If the record identifies a different congenital cataract subtype, code that more specific diagnosis instead.
Coding tip
Verify the patient’s age and the provider’s exact cataract description before assigning H26.09.
