Drug-induced cataract, unspecified eye

This code signifies a cataract that has developed as a direct result of medication use, where the specific drug causing the cataract is not identified. A cataract is a clouding of the eye's natural lens, leading to blurred vision. In this instance, the etiology is definitively linked to a pharmaceutical agent, but the laterality is not specified.

Use this code when documentation clearly states a drug-induced cataract but does not specify which eye is affected. This code is appropriate when the medical record indicates a causal link between medication and cataract formation, but the specific drug is unknown or not documented. Supporting documentation should include a physician's diagnosis of drug-induced cataract.

• Do not use this code if the specific drug causing the cataract is known; instead, use a more specific code from the H26.3- subcategory with an additional external cause code (T36-T50) to identify the drug.
• Avoid using this code if the laterality (right, left, or bilateral) is documented; choose the appropriate H26.31, H26.32, or H26.33 code.
• Ensure the documentation explicitly states "drug-induced" to differentiate from other cataract types.
