ICD-10 Code H25.13 – Age-related nuclear cataract, bilateral (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H25.13 – Age-related nuclear cataract, bilateral
What it is
H25.13 identifies age-related nuclear cataract in both eyes. This code is used when the lens opacity is in the nuclear region and is attributed to aging.
Clinical signs
Common findings include gradual, painless blurry vision, glare, and reduced distance vision. Clinical features vary; refer to documentation.
When to use this code
Use H25.13 when the provider documents bilateral age-related nuclear cataracts, or when the record clearly states nuclear cataract in both eyes. Apply it only when the age-related type and bilateral laterality are documented. Check documentation if laterality or cataract type is unclear.
Do not use for
Do not use this code for other cataract types, such as cortical or posterior subcapsular cataracts. Do not assign it when the cataract is not documented as bilateral or age-related.
Coding tip
Verify both the cataract type and laterality in the ophthalmology note before coding.
