Open angle with borderline findings, high risk, left eye

This code signifies a diagnosis of open-angle glaucoma in the left eye, where diagnostic findings are borderline but indicate a high risk of progression to definitive glaucoma. This often involves elevated intraocular pressure (IOP) and/or suspicious optic nerve head or visual field changes that do not yet meet criteria for established glaucoma.

Use this code when documentation clearly states "borderline findings" or "ocular hypertension with high risk" for the left eye, particularly when the patient is being closely monitored for glaucoma development. This applies to patients with risk factors such as family history, elevated IOP, or suspicious optic disc appearance.

• Ensure the documentation specifies "left eye" and "high risk" to support this specific code.
• Distinguish from H40.012 (open angle with borderline findings, low risk, left eye) based on the physician's assessment of risk.
• Do not use for established open-angle glaucoma; those conditions have their own specific codes.
