Unspecified primary angle-closure glaucoma, mild stage

This code signifies a form of glaucoma where the iris blocks the drainage angle of the eye, leading to increased intraocular pressure, without specifying laterality. The "mild stage" indicates minimal optic nerve damage and visual field loss.

Apply this code when documentation confirms primary angle-closure glaucoma without specifying if it affects the right, left, or both eyes, and the clinical assessment indicates a mild stage of the disease. This is appropriate when the provider has not documented the specific type of angle-closure (e.g., acute, chronic, intermittent) or the affected eye(s).

• Always query for laterality (right, left, bilateral) if not documented, as more specific codes exist.
• Ensure the documentation clearly supports "mild stage" based on optic nerve appearance and visual field testing.
• Avoid using this code if a more specific type of primary angle-closure glaucoma (e.g., acute, chronic, intermittent) is documented.
