Open angle with borderline findings, low risk, left eye

This code signifies a diagnosis of open-angle glaucoma suspect in the left eye, characterized by optic nerve or retinal nerve fiber layer findings that are considered borderline for glaucoma, but with a low risk of progression to definitive glaucoma. It indicates that while there are some suspicious signs, they do not yet meet the criteria for a definitive glaucoma diagnosis.

Use this code when documentation specifies "glaucoma suspect" or "ocular hypertension" with specific mention of borderline findings (e.g., suspicious optic disc cupping, nerve fiber layer thinning) in the left eye, and the clinician assesses the risk of progression as low. This code is appropriate for patients undergoing monitoring for potential glaucoma development.

• Ensure the documentation clearly specifies "left eye" and "low risk" for accurate laterality and risk assessment.
• Differentiate from codes for definitive open-angle glaucoma (H40.1x) or other types of glaucoma.
• This code often accompanies codes for ocular hypertension (H40.0x) if elevated intraocular pressure is also present.
