Unspecified dementia, severe, with agitation

This code signifies a severe, unspecified form of dementia characterized by significant cognitive decline and behavioral disturbances, specifically agitation. The patient exhibits substantial impairment in daily activities and requires extensive supervision, with agitation being a prominent and problematic symptom.

Apply this code when documentation clearly indicates a diagnosis of unspecified dementia that has progressed to a severe stage, and the patient is actively experiencing agitation. Supporting documentation should detail the severity of cognitive impairment and the presence and impact of agitated behaviors.

• Ensure documentation explicitly states "severe" and "agitation" in relation to unspecified dementia.
• Do not use this code if the specific type of dementia (e.g., Alzheimer's, vascular) is known; instead, use the appropriate code from F00-F02.
• Code any associated psychiatric symptoms or behavioral disturbances separately if they are distinct from the agitation component of the dementia.
