Unsp primary angle-closure glaucoma, indeterminate stage

This code signifies a form of glaucoma characterized by the closure of the anterior chamber angle, leading to elevated intraocular pressure, where the specific type of primary angle-closure glaucoma (e.g., acute, chronic, intermittent) is not documented. The "indeterminate stage" indicates that the severity of the glaucoma (e.g., mild, moderate, severe, or end-stage) cannot be determined from the available medical record.

Use this code when the physician's documentation confirms primary angle-closure glaucoma but does not specify the type (e.g., acute, chronic, intermittent) and does not provide sufficient information to classify the stage of the disease. This code is appropriate when the clinical picture suggests angle closure but further diagnostic workup or clarification is needed regarding its specific manifestation and progression.

• Only use this code when the documentation explicitly states "unspecified" or lacks details regarding the type and stage of primary angle-closure glaucoma.
• Avoid using this code if the documentation provides enough information to assign a more specific code for the type and stage of primary angle-closure glaucoma.
• Query the provider for clarification on the type and stage of glaucoma if possible, to allow for more precise coding.
