ICD-10 Code H25.10 – Age-related nuclear cataract, unspecified eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H25.10 – Age-related nuclear cataract, unspecified eye
What it is
This code identifies an age-related cataract affecting the central, nuclear portion of the lens in an unspecified eye. Use it when documentation confirms nuclear cataract but does not specify right or left eye.
Clinical signs
Typical findings include gradual, painless blurred vision, reduced contrast, and increasing glare or halos. Clinical features vary; refer to documentation and the eye examination record.
When to use this code
Use H25.10 when the provider documents age-related nuclear cataract and does not identify the eye involved. It also fits notes that describe nuclear sclerosis or nuclear cataract without laterality. If the record specifies a right or left eye, code to that more specific option instead.
Do not use for
Do not use this code for traumatic, congenital, diabetic, or other non-age-related cataracts. Do not use it when the chart clearly states a right or left eye.
Coding tip
Check the ophthalmology note for laterality before assigning the unspecified-eye code.
