ICD-10 Code H26.33 – Drug-induced cataract, bilateral (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H26.33 – Drug-induced cataract, bilateral
What it is
H26.33 identifies cataracts in both eyes that are caused by a medication or other drug exposure. Use it when the documentation states the cataract is drug-induced and bilateral.
Clinical signs
Clinical features vary; refer to documentation. Typical cataract findings include blurred vision, glare, reduced contrast, and lens opacity on eye examination.
When to use this code
Use this code when the provider documents bilateral cataracts attributed to a drug, such as a medication-related lens change. Apply it when both eyes are affected and the causal relationship is clearly stated. Check documentation if the record does not specify the drug cause.
Do not use for
Do not use H26.33 for cataracts without a drug cause or for unilateral drug-induced cataract. If the chart says only “cataract” or gives another specific etiology, choose the documented diagnosis instead.
Coding tip
Confirm both laterality and drug causation in the provider note before assigning H26.33.
