2026 ICD-10-CM Diagnosis Code H26.05 – Posterior subcapsular polar infantile and juvenile cataract
What it is
This code identifies a cataract with posterior subcapsular and polar features that begins in infancy or childhood. Use it for a lens opacity documented as congenital, infantile, or juvenile in onset.
Clinical signs
Typical findings include decreased visual acuity, glare, and cloudy or opaque lens changes on eye examination. Clinical features vary; refer to documentation.
When to use this code
Use H26.05 when the provider documents posterior subcapsular polar cataract affecting an infant or child, or when the diagnosis clearly states infantile or juvenile cataract with these features. You may also use it when the chart specifies the condition without additional laterality detail.
Do not use for
Do not use this code for age-related cataracts, traumatic cataracts, or other specified cataract types unless the record clearly supports H26.05. Check documentation.
Coding tip
Confirm the exact cataract type and onset age in the ophthalmology note before assigning H26.05.
