Unspecified glaucoma

This code represents a diagnosis of glaucoma where the specific type or cause of the condition has not been determined or documented by the provider. It indicates the presence of optic nerve damage and visual field loss characteristic of glaucoma, but without further classification.

Use this code when the physician's documentation clearly states "glaucoma" but does not specify the type (e.g., open-angle, angle-closure, secondary, congenital). This is often an initial diagnosis or when further diagnostic workup is pending. Avoid using this code if more specific information about the glaucoma type is available in the medical record.

• Always query the provider for a more specific type of glaucoma if documentation is ambiguous.
• Do not use this code if the documentation specifies any other type of glaucoma (e.g., primary open-angle glaucoma, acute angle-closure glaucoma).
• This code is a "not otherwise specified" (NOS) code and should be used only when no further information is available.
