Vascular dementia, severe, with anxiety

This code signifies a severe form of cognitive decline caused by cerebrovascular disease, characterized by significant impairment in multiple cognitive domains such as memory, executive function, and language. The patient also presents with co-occurring anxiety symptoms that are clinically significant and impact their daily functioning. This diagnosis indicates a substantial impact on the individual's independence and ability to perform activities of daily living.

This code is appropriate when documentation clearly indicates a diagnosis of vascular dementia that has progressed to a severe stage, along with a documented diagnosis of anxiety. The medical record should detail the severity of cognitive deficits, often requiring substantial assistance with personal care, and describe the presence and impact of anxiety symptoms. This code should be used when the clinician explicitly links the anxiety to the dementia or when it is a significant comorbidity in the context of severe vascular dementia.

• Ensure documentation specifies "severe" vascular dementia and explicitly mentions anxiety as a co-occurring symptom.
• Do not use if the anxiety is mild or not clinically significant in the context of the dementia.
• Consider sequencing if another mental health condition is the primary reason for the encounter, but the severe vascular dementia with anxiety is also being managed.
