Chronic angle-closure glaucoma, unsp eye, stage unspecified

This code signifies a persistent form of glaucoma characterized by a narrow or closed anterior chamber angle, leading to elevated intraocular pressure. It indicates that the specific eye affected (right or left) and the stage of the disease are not documented. This condition can cause irreversible optic nerve damage and vision loss if untreated.

Use this code when documentation confirms chronic angle-closure glaucoma but does not specify laterality (e.g., "chronic angle-closure glaucoma") and the stage of the disease is also unstated. This code is appropriate when the physician's notes lack detail regarding which eye is affected or the severity of the condition.

• Avoid using this code if laterality (right or left eye) or stage (mild, moderate, severe, indeterminate) is documented; more specific codes are available.
• Query the provider for clarification on laterality and stage to allow for more precise coding.
• This code should be used as a last resort when complete documentation for chronic angle-closure glaucoma is unavailable.
