ICD-10 Code H25.819 – Combined forms of age-related cataract, unspecified eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H25.819 – Combined forms of age-related cataract, unspecified eye
What it is
This code identifies an age-related cataract in which more than one lens opacity type is present, but the affected eye is not specified. Use it when the record confirms a combined senile cataract and laterality is not documented.
Clinical signs
Patients typically have gradually blurred vision, glare, and reduced contrast sensitivity. Clinical features vary; refer to documentation, but exam findings often include lens clouding consistent with cataract.
When to use this code
Use H25.819 when the provider documents combined forms of age-related cataract and does not identify the right or left eye. It also fits notes that describe mixed cataract changes without further laterality detail. If the record names a specific eye, code that laterality instead.
Do not use for
Do not use this code for traumatic, congenital, diabetic, or other non-age-related cataracts. Do not assign it when the documentation clearly specifies another cataract type or a different eye.
Coding tip
Check the ophthalmology note for laterality before defaulting to the unspecified-eye code.
