ICD-10 Code H26.22 – Cataract Secondary to Ocular Disorders (Degenerative) (Inflammatory) (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H26.22 – Cataract secondary to ocular disorders (degenerative) (inflammatory)
What it is
This code identifies a cataract that develops because of another eye disorder, such as a degenerative or inflammatory condition. Use it when the documentation shows the cataract is secondary to an ocular disease rather than age-related change.
Clinical signs
Typical findings include blurred or cloudy vision, glare, and reduced visual acuity. Clinical features vary; refer to documentation for the underlying ocular disorder and the cataract relationship.
When to use this code
Use H26.22 when the provider documents cataract due to an inflammatory or degenerative eye condition, or states the cataract is secondary to another ocular disorder. The record should link the cataract to the eye disease. Check documentation if the cause is not clearly stated.
Do not use for
Do not use this code for age-related cataracts, traumatic cataracts, or cataracts from non-ocular causes. If the chart does not specify the secondary cause, check documentation.
Coding tip
Assign the underlying eye disorder code as well, when documented, to show the full clinical picture.
