ICD-10 Code H26.01 – Infantile and juvenile cortical, lamellar, or zonular cataract (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H26.01 – Infantile and juvenile cortical, lamellar, or zonular cataract
What it is
This code identifies a cataract that develops in infancy or childhood and affects the lens cortex, lamellae, or zonular area. Use it when the record clearly describes one of these juvenile cataract patterns.
Clinical signs
Typical findings include lens opacity noted on eye examination, reduced visual acuity, leukocoria, or abnormal visual development. Clinical features vary; refer to documentation.
When to use this code
Use H26.01 when the provider documents an infantile or juvenile cataract with cortical, lamellar, or zonular involvement. It also fits ophthalmology notes that specify these anatomic patterns without another more specific cataract type. If the chart only says “childhood cataract,” check documentation before coding.
Do not use for
Do not use this code for congenital cataract unless the documentation specifically supports infantile or juvenile onset. Do not apply it when the cataract type or age at onset is unclear; check documentation.
Coding tip
Match the code to the provider’s exact cataract description and age wording; do not infer juvenile onset from a pediatric visit alone.
