Open angle with borderline findings, low risk, unsp eye

This code signifies a diagnosis of open-angle glaucoma suspect where the optic nerve or visual field findings are considered borderline, indicating a low risk of progression to definitive glaucoma. It represents an early stage of concern for glaucoma, without specifying laterality.

Use this code when a patient presents with suspicious but not definitive signs of open-angle glaucoma, such as borderline optic disc cupping, nerve fiber layer thinning, or visual field defects that do not meet criteria for established glaucoma. Documentation should clearly state "borderline findings," "low risk," or "glaucoma suspect" without specifying left or right eye.

• Avoid using this code if laterality (left or right eye) is documented; instead, use the more specific codes for right (H40.011) or left (H40.012) eye.
• Do not use this code for established open-angle glaucoma; those conditions have their own specific codes.
• Ensure the documentation explicitly states "borderline findings" and "low risk" to support the use of this specific code.
