Dem in other dis classd elswhr, unsp severt, with agitation

This diagnosis 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 presents with agitation as a behavioral symptom.

Apply this code when documentation clearly links dementia to a specific, separately classifiable disease (e.g., Parkinson's disease, Huntington's disease, HIV disease) and agitation is noted. Ensure the medical record explicitly states the underlying disease and the presence of agitation.

• Always sequence the underlying disease causing the dementia first, followed by this code.
• Do not use this code for primary dementias (e.g., Alzheimer's, vascular dementia) or when the underlying cause is unknown.
• Look for specific documentation of "agitation" or similar terms (e.g., restlessness, aggression, combative behavior) in the context of the dementia.
