Infantile & juv cortical/lamellar/zonular cataract, unsp eye

This code describes a congenital or early-onset cataract affecting the lens cortex, lamellae, or zonules in infants or juveniles, without specifying laterality. This type of cataract obstructs light passage, leading to impaired vision in young patients. It is distinct from age-related cataracts and other specific types of congenital cataracts.

Use this code when documentation indicates an infantile or juvenile cortical, lamellar, or zonular cataract, and the specific eye affected (right, left, or bilateral) is not documented. This diagnosis is typically made by an ophthalmologist based on slit-lamp examination and patient history. Supporting documentation should clearly state the cataract type and the patient's age group.

• Only use this code when the laterality is truly unspecified in the medical record.
• Review documentation carefully for more specific cataract types (e.g., H26.03- for traumatic, H26.04- for drug-induced).
• Always attempt to query the provider for laterality if not documented to allow for a more specific code assignment.
