Unspecified dementia, severe, without beh/psych/mood/anx

This code signifies a diagnosis of dementia of an unspecified type that has progressed to a severe stage. The patient exhibits significant cognitive decline impacting daily functioning, but without any co-occurring behavioral, psychotic, mood, or anxiety symptoms.

Use this code when documentation clearly states "severe dementia" without further specification of the dementia type (e.g., Alzheimer's, vascular) and explicitly rules out behavioral disturbances, psychotic features, mood disorders, or anxiety. This code is appropriate when the physician has assessed and confirmed the absence of these specific neuropsychiatric symptoms.

• Always seek further specificity regarding the type of dementia if available in the medical record.
• Ensure documentation explicitly negates behavioral, psychotic, mood, and anxiety disturbances.
• Do not use this code if any of the excluded disturbances are present; instead, select a more specific code that includes those manifestations.
