Unspecified open-angle glaucoma, stage unspecified

This code signifies a diagnosis of open-angle glaucoma where the specific type (e.g., primary, secondary) has not been documented, and the stage of the disease progression is also unknown. It indicates elevated intraocular pressure causing optic nerve damage and visual field loss, characteristic of open-angle glaucoma, but lacks further diagnostic specificity.

Use this code when the medical record clearly states "open-angle glaucoma" but provides no further detail regarding its etiology or severity/stage. This is appropriate when initial diagnostic workup is incomplete, or the physician has not yet determined the specific type or stage of the glaucoma. Documentation should explicitly state "unspecified open-angle glaucoma" or similar.

• Avoid using this code if the documentation specifies the type of open-angle glaucoma (e.g., primary open-angle glaucoma, pigmentary glaucoma) or the stage (e.g., mild, moderate, severe).
• Always query the provider for more specific information regarding the type and stage of glaucoma to allow for more precise coding.
• This code should be considered a temporary code until more definitive diagnostic information is available.
