H2513 - Age-related clouding of the natural lens in both eyes (cataracts)

International Classification of Diseases

Last updated: 10/3/2025

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 that you have cataracts in both eyes. Cataracts occur when the natural lens inside your eye becomes cloudy, making your vision blurry or dim. The 'nuclear' type means the cloudiness is in the center part of the lens. This is a very common condition that develops naturally as we age, typically affecting people over 60. The cloudiness blocks light from reaching the back of your eye clearly, which is why you may notice difficulty seeing, especially at night, increased glare from lights, or colors appearing faded. This is not an emergency condition and develops gradually over time.

Additional Information

This is a diagnosis code only and does not indicate any specific treatment was performed. Cataracts are very treatable with surgery when they begin to significantly impact your quality of life or daily activities.
