ICD-10 Code H26.30 – Drug-induced cataract, unspecified eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H26.30 – Drug-induced cataract, unspecified eye
What it is
This code identifies a cataract believed to be caused by a medication or other drug exposure, when the affected eye is not specified. It reflects lens clouding attributed to a drug effect, not a congenital or traumatic cataract.
Clinical signs
Clinical features vary; refer to documentation. Common findings include blurred vision, glare, and reduced visual clarity, with cataract changes noted on eye examination.
When to use this code
Use H26.30 when the provider documents a cataract as drug-induced and does not specify right or left eye. It is appropriate when the record links the lens opacity to medication exposure and no more precise eye laterality is available. Check documentation if the cause is uncertain.
Do not use for
Do not use this code for age-related cataracts, traumatic cataracts, or cataracts with a different documented cause. If the affected eye is specified, use the laterality-specific code instead.
Coding tip
Confirm both causation and laterality in the note before assigning H26.30.
