ICD-10 Code H26.32 – Drug-induced cataract, left eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H26.32 – Drug-induced cataract, left eye
What it is
This code identifies a cataract in the left eye that is caused by a medication or other drug exposure. It tells you the laterality and that the lens opacity is drug-induced, not age-related.
Clinical signs
Typical findings include progressive lens opacity, blurred vision, glare, or reduced visual acuity. Clinical features vary; refer to documentation for the causal drug and eye-specific findings.
When to use this code
Use H26.32 when the provider documents a cataract in the left eye and states it is due to drug exposure. This is appropriate when the record clearly links the cataract to medication use, adverse effect, or other drug-induced cause. If the cause is not documented, check documentation.
Do not use for
Do not use this code for age-related cataracts, traumatic cataracts, or cataracts without a documented drug cause. Do not assign it when the affected eye is not specified or the record only says “cataract.”
Coding tip
Verify that the left eye and the drug-induced etiology are both documented before assigning H26.32.
