ICD-10 Code H40.60 – Glaucoma secondary to drugs, unspecified eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H40.60 – Glaucoma secondary to drugs, unspecified eye
What it is
This code identifies glaucoma caused by a medication or drug effect, but the affected eye is not specified. Use it when the record links elevated eye pressure or glaucomatous damage to a drug exposure.
Clinical signs
Findings may include increased intraocular pressure, optic nerve changes, or visual field loss. Clinical features vary; refer to documentation.
When to use this code
Use H40.60 when the provider documents glaucoma secondary to a drug and does not identify the right, left, or bilateral eye. It also fits when the chart clearly supports a drug-related cause but laterality is absent or unclear. Check documentation if the medication name or causal relationship is uncertain.
Do not use for
Do not use this code for primary glaucoma or for unspecified eye disease without a documented drug cause. If the laterality is stated, select the more specific code.
Coding tip
Confirm both the drug-related etiology and the unspecified eye designation before assigning H40.60.
