ICD-10 Code H26 – Other cataract (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H26 – Other cataract
What it is
H26 identifies cataracts that do not fit a more specific category. Use it for lens opacity when the record documents an “other” cataract type rather than age-related, traumatic, congenital, or drug-induced disease.
Clinical signs
Clinical features vary; refer to documentation. Common findings include gradual blurred vision, glare, reduced contrast, and lens opacity on eye examination.
When to use this code
Use H26 when the provider documents an unspecified “other cataract” or a cataract type not captured by a more specific ICD-10 code. It may apply when the note identifies cataract morphology or cause, but not enough detail for a narrower code. Check documentation if the record suggests a more specific cataract category.
Do not use for
Do not use H26 for age-related, congenital, traumatic, or drug-induced cataracts when those are documented. Also avoid it when the chart supports a more specific cataract code.
Coding tip
Query the provider for laterality, cause, and cataract type if the note only says “cataract.”
