Vascular dementia, moderate, without beh/psych/mood/anx

This code signifies a form of dementia caused by cerebrovascular disease, characterized by a moderate decline in cognitive function. The patient exhibits impaired memory, executive function, or other cognitive domains, but without any associated behavioral, psychotic, mood, or anxiety symptoms.

Use this code when documentation explicitly states "vascular dementia, moderate" and specifically negates the presence of behavioral disturbances, psychotic symptoms, mood disorders, or anxiety. This diagnosis is typically made after neurocognitive testing and imaging confirm vascular etiology and the absence of these specific neuropsychiatric features.

• Ensure the documentation clearly specifies "moderate" severity and explicitly rules out behavioral, psychotic, mood, and anxiety disturbances.
• Do not use this code if any of the excluded behavioral or psychological symptoms are present; a more specific code from the F01.B category would be appropriate.
• Consider sequencing this code after codes for the underlying cerebrovascular disease (e.g., I69.351, I69.359) if applicable and still active.
