Dem in other dis classd elswhr, moderate, with mood disturb

This code signifies a moderate level of cognitive decline and functional impairment due to dementia that is secondary to another underlying medical condition. The patient also exhibits significant mood disturbances, such as depression, anxiety, or irritability, directly related to their dementia.

Apply this code when documentation clearly indicates moderate dementia caused by a specific, separately classifiable disease (e.g., Parkinson's disease, Huntington's disease, HIV disease) and the patient presents with clinically significant mood symptoms. The medical record must specify both the severity of dementia and the presence of mood disturbance.

• Always code the underlying disease causing the dementia first, followed by this code.
• Ensure the documentation explicitly states "moderate" dementia and describes the mood disturbance.
• Do not use this code for unspecified dementia, Alzheimer's disease, or vascular dementia, as those have their own specific codes.
