This code signifies severe dementia that is a manifestation of another underlying medical condition, rather than primary Alzheimer's disease or vascular dementia. The patient exhibits significant cognitive decline impacting daily activities, but without associated behavioral, psychotic, mood, or anxiety symptoms. The dementia is secondary to a separately classified disease.

Apply this code when documentation clearly states severe dementia due to another specified disease (e.g., Parkinson's disease, Huntington's disease, HIV disease) and explicitly rules out behavioral, psychotic, mood, or anxiety disturbances. The medical record must confirm the severity level and the absence of these specific neuropsychiatric symptoms.

• Always sequence the underlying disease causing the dementia first, followed by this code.
• Ensure documentation explicitly states "severe" dementia and the absence of behavioral, psychotic, mood, or anxiety disturbances.
• Do not use this code if the dementia is primary (e.g., Alzheimer's) or if any of the excluded behavioral or psychological symptoms are present.
