ICD-10 Code H26.033 – Infantile and juvenile nuclear cataract, bilateral (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H26.033 – Infantile and juvenile nuclear cataract, bilateral
What it is
This code identifies a nuclear cataract affecting both eyes in an infant or child. It means the central lens opacity is present early in life and is documented as bilateral.
Clinical signs
Typical findings include decreased visual clarity, abnormal red reflex, or a visible central lens opacity on eye exam. Clinical features vary; refer to documentation.
When to use this code
Use H26.033 when the provider documents infantile or juvenile nuclear cataract in both eyes. Apply it when the record clearly states bilateral involvement, even if the cataract is found during routine pediatric eye evaluation.
Do not assume laterality from a single-eye finding or from unspecified cataract wording. If the note only says cataract or lens opacity without age-related detail, check documentation before coding.
Do not use for
Do not use this code for unilateral nuclear cataract or for adult-onset cataracts. Also avoid it when the documentation does not confirm both infantile or juvenile onset and bilateral involvement.
Coding tip
Confirm both age-related wording and laterality in the ophthalmology note before assigning H26.033.
