Chronic angle-closure glaucoma, right eye, moderate stage

This code signifies a chronic form of angle-closure glaucoma affecting the right eye, characterized by a persistently narrow or closed anterior chamber angle leading to impaired aqueous humor outflow. The condition has progressed to a moderate stage, indicating a measurable degree of optic nerve damage and visual field loss.

Apply this code when documentation confirms a diagnosis of chronic angle-closure glaucoma in the right eye, and the physician explicitly states or implies a "moderate" stage of the disease based on clinical findings such as visual field defects or optic nerve cupping. This code is appropriate for ongoing management and monitoring of established chronic angle-closure glaucoma.

• Ensure documentation clearly specifies "chronic" and not "acute" angle-closure glaucoma.
• Verify the affected eye (right) and the stage of glaucoma (moderate) are explicitly stated in the medical record.
• Do not confuse with codes for primary open-angle glaucoma or other types of glaucoma.
