Chr angle-closure glaucoma, unsp eye, indeterminate stage

This code signifies a diagnosis of chronic angle-closure glaucoma where the specific eye affected is not documented, and the stage of the disease is also undetermined. This form of glaucoma is characterized by a persistently narrow or closed anterior chamber angle, leading to elevated intraocular pressure and potential optic nerve damage.

Use this code when the medical record clearly states chronic angle-closure glaucoma but does not specify whether it affects the right or left eye, or if it's bilateral. It is also appropriate when the physician's documentation does not indicate a specific stage of the glaucoma (e.g., mild, moderate, severe).

• Avoid using this code if the laterality (right, left, bilateral) or stage of glaucoma is documented; instead, choose a more specific code.
• Query the provider for clarification on laterality and stage to allow for more precise coding.
• This code should be sequenced as a primary diagnosis when it is the reason for the encounter, or as a secondary diagnosis when it is a co-morbidity.
