Unsp primary angle-closure glaucoma, stage unspecified

This code signifies a form of glaucoma where the drainage angle of the eye is closed, leading to increased intraocular pressure, but the specific cause (e.g., acute, chronic, intermittent) and the severity of the disease are not documented. It indicates a primary angle-closure mechanism without further detail regarding the clinical presentation or the extent of optic nerve damage.

Use this code when the physician's documentation clearly states "primary angle-closure glaucoma" but does not specify whether it is acute, chronic, intermittent, or the stage of the disease. This code is appropriate when the clinical information is insufficient to assign a more specific code for angle-closure glaucoma.

• Avoid using this code if documentation provides details on the type (e.g., acute, chronic) or stage of angle-closure glaucoma.
• Always query the provider for more specific information if available to assign a more precise code.
• This code is a "catch-all" for unspecified cases; strive for greater specificity whenever possible.
