Low-tension glaucoma, unspecified eye, indeterminate stage

This code describes a form of 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 is not documented, and the severity or progression of the disease cannot be determined.

Use this code when documentation confirms a diagnosis of low-tension glaucoma but does not specify whether it affects the right or left eye, or if it's bilateral. This code is also appropriate when the physician's assessment does not indicate a specific stage (e.g., mild, moderate, severe, or end-stage).

• Avoid using this code if the affected eye (right, left, or bilateral) is clearly documented; instead, select a more specific code.
• Do not use this code if the stage of glaucoma is specified in the medical record; query the provider for clarification if needed.
• This code is for diagnosis only; it does not represent a procedure or service.
