Age-related nuclear cataract, unspecified eye

This code signifies a cataract primarily affecting the nucleus of the lens, which is a common age-related degenerative condition. It results in a gradual opacification and hardening of the central lens, leading to progressive vision impairment. This specific code is used when the affected eye is not specified in the medical record.

Use this code when documentation clearly indicates an age-related nuclear cataract but does not specify whether it affects the right, left, or both eyes. This often occurs when the laterality is not explicitly stated, or when the patient presents with symptoms consistent with a nuclear cataract without a definitive laterality diagnosis at the time of coding.

• Always attempt to clarify laterality with the provider if not specified, as more specific codes exist (H25.11, H25.12, H25.13).
• Do not use this code if the documentation specifies a different type of age-related cataract (e.g., cortical, subcapsular).
• This code is a primary diagnosis for cataract extraction procedures when laterality is unknown.
