Residual stage of open-angle glaucoma, right eye

This code signifies the permanent, irreversible damage to the optic nerve and visual field loss in the right eye resulting from previously active open-angle glaucoma. It indicates that the active disease process has stabilized, but the structural and functional consequences remain. This is a chronic, non-progressive state following successful treatment or natural arrest of the glaucoma.

Use this code when documentation confirms a history of open-angle glaucoma in the right eye, with current findings indicating stable, non-progressive optic nerve damage and visual field defects. This applies when the intraocular pressure is controlled, and no further active glaucomatous progression is noted. Supporting documentation includes ophthalmology notes detailing optic nerve head appearance, visual field tests, and a clear statement of "residual" or "inactive" glaucoma.

• Do not use this code if the glaucoma is still active or progressing; instead, use an appropriate code for the specific type and stage of active open-angle glaucoma.
• Laterality is crucial; ensure documentation specifies the right eye. If both eyes are affected, separate codes for each eye or a bilateral code (if available) would be necessary.
• This code should be sequenced as a secondary diagnosis if the patient is being treated for complications directly related to the residual damage (e.g., low vision).
