Chronic angle-closure glaucoma, r eye, indeterminate stage

This code signifies a chronic form of angle-closure glaucoma affecting the right eye, where the specific stage of the disease progression cannot be definitively determined. This condition involves elevated intraocular pressure due to a physically obstructed drainage angle, leading to optic nerve damage and potential vision loss.

Apply this code when documentation clearly indicates chronic angle-closure glaucoma in the right eye, but the ophthalmologist is unable to assign a specific stage (e.g., mild, moderate, severe) due to insufficient information or ongoing evaluation. This is appropriate when the physician explicitly states "indeterminate stage" or similar phrasing.

• Ensure laterality is accurately documented for the right eye.
• Do not use this code if a specific stage of glaucoma (e.g., mild, moderate, severe) is documented; instead, select the appropriate stage-specific code.
• Confirm that the "chronic" nature of the angle-closure glaucoma is explicitly stated to differentiate from acute or subacute forms.
