2026 ICD-10-CM Diagnosis Code H26.042 – Anterior subcapsular polar infantile and juvenile cataract, left eye
What it is
This code identifies a cataract located at the front part of the lens capsule in the left eye, present in infancy or childhood. It describes a specific lens opacity, not a cause or treatment.
Clinical signs
Clinical features vary; refer to documentation. You may see decreased visual acuity, abnormal red reflex, or a visible anterior lens opacity in the left eye.
When to use this code
Use H26.042 when the record clearly documents an anterior subcapsular polar infantile or juvenile cataract in the left eye. Code it when the diagnosis is confirmed by an eye specialist or supported by exam findings. Check documentation if laterality or age-related wording is unclear.
Do not use for
Do not use this code for cataracts in another eye, bilateral cataracts, or cataracts with a different anatomic location. If the type is not specified, check documentation.
Coding tip
Verify both laterality and cataract subtype before assigning H26.042.
