Open angle with borderline findings, low risk, right eye

This code signifies a diagnosis of open-angle glaucoma suspect in the right eye, characterized by ocular findings that are borderline for glaucoma but currently present a low risk of progression. It indicates that the intraocular pressure (IOP) and optic nerve head (ONH) or visual field (VF) parameters are suspicious but do not yet meet the criteria for a definitive glaucoma diagnosis.

Use this code when documentation specifies "glaucoma suspect" or "pre-glaucoma" with open-angle characteristics in the right eye, and findings are explicitly noted as borderline or low risk. This typically applies to patients undergoing monitoring for elevated IOP without definitive glaucomatous damage, or those with suspicious ONH appearance or VF defects that are not yet clearly indicative of glaucoma.

• Ensure the documentation clearly specifies "right eye" and "low risk" or "borderline findings."
• Do not use this code if definitive glaucomatous damage is present; instead, select a code for primary open-angle glaucoma.
• Distinguish from codes for ocular hypertension without borderline findings (H40.00x) or other types of glaucoma suspects.
