ICD-10 Code H26.039 – Infantile and Juvenile Nuclear Cataract, Unspecified Eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H26.039 – Infantile and juvenile nuclear cataract, unspecified eye
What it is
This code identifies a nuclear cataract that begins in infancy or childhood and affects an unspecified eye. Use it when the record documents the type of cataract but does not state right or left eye.
Clinical signs
Typical findings include lens opacity in the central nucleus, with reduced visual clarity or abnormal red reflex. Clinical features vary; refer to documentation.
When to use this code
Use H26.039 when the provider diagnoses infantile or juvenile nuclear cataract and does not specify laterality. It also fits ophthalmology notes describing a congenital or early-onset nuclear lens opacity without further eye detail. If the chart names a different cataract type, check documentation.
Do not use for
Do not use this code for age-related cataracts, traumatic cataracts, or cataracts with a documented right or left eye. Check documentation if the cataract type or laterality is unclear.
Coding tip
Verify both onset category and laterality before assigning H26.039.
