Low-tension glaucoma, unspecified eye, stage unspecified

This code signifies a form of primary open-angle glaucoma characterized by optic nerve damage and visual field loss despite intraocular pressure (IOP) consistently remaining within the statistically normal range. It indicates that the specific eye affected and the stage of the condition have not been documented.

Apply this code when the physician's documentation confirms a diagnosis of low-tension glaucoma but does not specify laterality (e.g., "low-tension glaucoma, unspecified eye") or the stage of the disease. This code is appropriate when the medical record lacks the granular detail to assign a more specific code for eye or stage.

• Avoid using this code if the documentation specifies the affected eye (right, left, bilateral) or the stage of glaucoma.
• Always query the provider for clarification on laterality and stage to allow for more specific coding.
• Do not confuse with other types of open-angle glaucoma where IOP is elevated.
