Vascular dementia, moderate, with anxiety

This code signifies a form of dementia caused by cerebrovascular disease, characterized by a moderate decline in cognitive function. Patients present with noticeable impairments in memory, executive function, and other cognitive domains, accompanied by significant symptoms of anxiety. The cognitive deficits are severe enough to interfere with daily activities but the patient can still perform some complex tasks.

Apply this code when documentation clearly indicates a diagnosis of vascular dementia at a moderate severity level, and anxiety is a clinically significant co-occurring symptom. This typically follows a neurological assessment confirming the vascular etiology and the moderate impact on cognitive abilities, along with a psychiatric evaluation or clinical observation noting the presence and impact of anxiety.

• Ensure the documentation specifies "moderate" severity for the vascular dementia; avoid using this code for mild or severe presentations.
• Verify that anxiety is explicitly documented as present and associated with the dementia, not as a separate, unrelated condition.
• Differentiate from Alzheimer's disease with vascular components; the primary etiology must be vascular for this code.
