ICD-10 Code H26.012 – Infantile and Juvenile Cortical, Lamellar, or Zonular Cataract, Left Eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H26.012 – Infantile and juvenile cortical, lamellar, or zonular cataract, left eye
What it is
This code identifies a cataract affecting the left eye in infancy or childhood, with opacity in the cortical, lamellar, or zonular portion of the lens. Use it when the record specifically documents this congenital or juvenile pattern.
Clinical signs
Clinical features may include reduced visual clarity, abnormal red reflex, or lens opacity seen on eye examination. Clinical features vary; refer to documentation.
When to use this code
Use H26.012 when the provider documents infantile or juvenile cortical, lamellar, or zonular cataract in the left eye. It is appropriate for ophthalmology notes, problem lists, and claims that specify laterality. If the note only says “cataract,” check documentation for type and eye.
Do not use for
Do not use this code for cataracts in the right eye, both eyes, or unspecified eye. Also avoid it when the chart does not confirm the infantile or juvenile cortical, lamellar, or zonular type.
Coding tip
Verify both laterality and cataract subtype before assigning H26.012.
