Dem in other dis classd elswhr, unsp sev, with psych distrb

This code signifies a form of dementia that arises as a manifestation of another underlying medical condition, rather than being a primary neurodegenerative disorder. The patient exhibits cognitive decline of unspecified severity, accompanied by psychotic symptoms such as hallucinations or delusions.

Apply this code when documentation clearly indicates dementia secondary to another specified disease (e.g., Parkinson's disease, Huntington's disease, HIV disease) and the patient is experiencing psychotic features. The medical record must specify the underlying disease causing the dementia and the presence of psychosis.

• Always sequence the underlying disease causing the dementia first, followed by this code.
• Do not use this code for Alzheimer's dementia or vascular dementia; specific codes exist for those conditions.
• Ensure the documentation explicitly states "with psychotic disturbance" or describes specific psychotic symptoms.
