H259 - Age-related cataract, type not specified

International Classification of Diseases

Last updated: 3/24/2026

What is a ICD-10 Code?

ICD-10 (International Classification of Diseases, 10th Revision) codes are used to classify and code all diagnoses, symptoms, and procedures recorded in association with hospital care. These codes provide a standardized way to track health conditions and their treatment outcomes.

Detailed Description

This code indicates you have a cataract (clouding of the natural lens in your eye) that is related to aging, but the specific type or stage of the cataract has not been specified in your medical record. Cataracts are very common as people get older and typically develop gradually, causing blurry vision, increased glare sensitivity, and difficulty seeing in low light. The lens becomes cloudy over time, which interferes with clear vision.

Additional Information

This is a general diagnostic code used when the provider has identified an age-related cataract but has not documented the specific type (nuclear, cortical, posterior subcapsular, etc.) or laterality (which eye). Most age-related cataracts progress slowly and may not require immediate treatment.
