ICD-10 Code H40.011 – Open angle with borderline findings, low risk, right eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H40.011 – Open angle with borderline findings, low risk, right eye
What it is
This code identifies a right-eye glaucoma suspect with open-angle anatomy and borderline findings, but low estimated risk of progression. It is used when the chart documents suspicious optic nerve or pressure findings without established glaucoma.
Clinical signs
Findings may include a suspicious optic disc, borderline intraocular pressure, or other glaucoma-suspect features. Clinical features vary; refer to documentation.
When to use this code
Use H40.011 when the provider documents open-angle borderline findings in the right eye and explicitly describes the risk as low. This is appropriate for follow-up visits, surveillance exams, or problem lists when glaucoma has not been confirmed. Check documentation if laterality or risk level is unclear.
Do not use for
Do not use this code for confirmed open-angle glaucoma, ocular hypertension alone, or findings in the left eye or both eyes. If the record does not support low risk, check documentation.
Coding tip
Verify the eye and risk level in the ophthalmology note before assigning H40.011.
