Unspecified glaucoma

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

This code is appropriate when the medical record clearly states a diagnosis of "glaucoma" but lacks information to classify it further (e.g., open-angle, angle-closure, primary, secondary, or stage). It may be used in initial assessments or when a definitive diagnosis has not yet been established after diagnostic workup.

• Avoid using this code if more specific documentation is available; always query the provider for clarification.
• This code is often a placeholder and should ideally be replaced with a more specific glaucoma code once further diagnostic information is obtained.
• Do not confuse this with codes for ocular hypertension (H40.0x) or suspected glaucoma (H40.00x), which are distinct conditions.
