ICD-10 Code H40.61 – Glaucoma Secondary to Drugs, Right Eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H40.61 – Glaucoma secondary to drugs, right eye
What it is
This code identifies glaucoma in the right eye that is caused by a medication or other drug exposure. Use it when the documentation clearly links the elevated eye pressure or optic nerve damage to the drug.
Clinical signs
Findings may include increased intraocular pressure, optic nerve cupping, or visual field loss in the right eye. Clinical features vary; refer to documentation.
When to use this code
Use this code when the provider documents drug-induced glaucoma affecting the right eye. It may apply when the note states the glaucoma is secondary to a specific medication, toxic effect, or steroid exposure. If laterality is recorded as right eye, code it accordingly.
Do not use for
Do not use this code for primary glaucoma or for glaucoma in another eye. If the record does not clearly connect the condition to a drug, check documentation.
Coding tip
Confirm both the drug cause and right-eye laterality in the note before assigning H40.61.
