ICD-10 Code H26.222 – Cataract secondary to ocular disorders (degenerative) (inflammatory), left eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H26.222 – Cataract secondary to ocular disorders (degenerative) (inflammatory), left eye
What it is
This code identifies a cataract in the left eye that develops because of another eye disorder, such as a degenerative or inflammatory condition. Use it when the record clearly links the cataract to that underlying ocular disease.
Clinical signs
Common findings include lens opacity, blurred or reduced vision, glare, and difficulty with visual tasks. Clinical features vary; refer to documentation for the underlying ocular disorder and laterality.
When to use this code
Use H26.222 when the provider documents a secondary cataract in the left eye caused by a degenerative or inflammatory eye disorder. Code the underlying condition as well when it is documented and applicable. Check documentation if the cause, eye, or cataract type is unclear.
Do not use for
Do not use this code for age-related, traumatic, congenital, or unspecified cataracts. Do not assign it if the chart does not support a left-eye cataract secondary to another ocular disorder.
Coding tip
Verify both the secondary cause and the left-eye laterality before assigning H26.222.
