Residual stage of open-angle glaucoma, bilateral

This code signifies the permanent, non-progressive damage to the optic nerve and visual field loss resulting from open-angle glaucoma, affecting both eyes. It indicates that the active disease process has stabilized, but the structural and functional deficits remain.

Use this code when documentation confirms bilateral open-angle glaucoma has progressed to a stable, residual stage, meaning further deterioration is not expected, but existing damage persists. This typically applies to patients who have undergone treatment (e.g., surgery, long-term medication) and are now in a maintenance phase with stable intraocular pressure and visual fields.

• Always confirm "residual stage" and "bilateral" in the physician's documentation.
• Do not use this code if the glaucoma is still active or progressive; instead, use codes for primary open-angle glaucoma with stage.
• Sequence this code as a secondary diagnosis if the patient is being treated for a current complication or sequela directly related to the residual glaucoma.
