Drug-induced cataract, right eye

This code signifies a cataract that has developed in the right eye as a direct consequence of medication use. This condition involves the clouding of the eye's natural lens, leading to impaired vision, and is specifically attributed to an adverse drug effect.

Apply this code when documentation clearly indicates a cataract in the right eye caused by a prescribed or illicit drug. Supporting documentation should include a definitive link between drug exposure and cataract formation, often noted by an ophthalmologist or optometrist.

• Always identify the specific drug causing the cataract using an additional code from T36-T50 (Poisoning by, adverse effect of and underdosing of drugs, medicaments and biological substances).
• Ensure the laterality (right eye) is explicitly documented; do not assume.
• Distinguish from age-related or other types of cataracts; the drug etiology must be confirmed.
