ICD-10 Code H25.0 – Age-related incipient cataract (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H25.0 – Age-related incipient cataract
What it is
Age-related incipient cataract means an early lens opacity caused by aging. The cataract is present, but it has not yet become advanced enough to cause major lens clouding.
Clinical signs
Patients may report mild blurred vision, glare, or reduced contrast, though findings can be subtle. Clinical features vary; refer to documentation.
When to use this code
Use H25.0 when the provider documents an age-related cataract in an early or incipient stage. It fits cases where the cataract is senile or age-related and the record does not describe a different cataract type.
Code it from ophthalmology notes, exam findings, or assessment lists that clearly identify incipient age-related cataract. Check documentation if the note only says “cataract” without staging or age-related wording.
Do not use for
Do not use this code for traumatic, congenital, diabetic, or drug-induced cataracts. It is also not appropriate when the documentation describes a mature cataract or another specific lens disorder.
Coding tip
Match the stage and cause exactly; if the record does not specify age-related incipient cataract, check documentation before assigning H25.0.
