Unspecified dementia, severe, with anxiety

This code signifies a severe, unspecified form of dementia where the patient exhibits significant anxiety. The cognitive decline is profound, impacting daily functioning, and the anxiety component is a prominent and clinically significant symptom.

Apply this code when documentation clearly indicates a diagnosis of severe dementia without a more specific etiology (e.g., Alzheimer's, vascular) and the patient is experiencing clinically significant anxiety. This is appropriate when the physician explicitly states "severe dementia with anxiety" and no further specification of the dementia type is provided.

• Ensure the documentation explicitly states "severe" dementia and identifies anxiety as a co-occurring symptom.
• Avoid using this code if a more specific type of dementia (e.g., F01.C4, F02.84) is documented; always code to the highest level of specificity.
• Do not use this code if the anxiety is mild or transient and not a significant clinical feature of the dementia.
