Dem in other dis classd elswhr, unsp severity, with anxiety

This code signifies dementia that is a manifestation of another underlying medical condition, rather than a primary neurodegenerative disorder like Alzheimer's. The severity of the dementia is not specified, and the patient also experiences anxiety symptoms. This diagnosis indicates a complex presentation where cognitive decline is secondary to another disease process.

Use this code when documentation clearly links dementia to another specified disease (e.g., Parkinson's disease, Huntington's disease, HIV disease, multiple sclerosis) and anxiety is also present. The physician's notes must explicitly state the underlying disease causing the dementia and mention the presence of anxiety. This code is appropriate when the severity of the dementia is not clinically determined or documented.

• Ensure the underlying disease causing the dementia is also coded, as this code is for dementia "in other diseases classified elsewhere."
• Do not use this code for primary dementias like Alzheimer's disease; refer to codes within the F00 category for those conditions.
• Verify that anxiety is explicitly documented as a current symptom alongside the dementia.
