Age-related nuclear cataract, left eye

This code describes a type of cataract affecting the nucleus of the lens, specifically in the left eye, that is associated with the aging process. It signifies a progressive clouding and hardening of the central portion of the lens, leading to impaired vision.

Use this code when documentation clearly indicates a diagnosis of age-related nuclear cataract affecting the patient's left eye. This diagnosis is typically made by an ophthalmologist based on slit-lamp examination findings.

• Always specify laterality (left, right, or bilateral) when documented.
• Distinguish from other types of age-related cataracts (e.g., cortical, subcapsular) and non-age-related cataracts.
• Ensure the documentation explicitly states "nuclear" and "age-related" for accurate code assignment.
