Vascular dementia, moderate, with psychotic disturbance

This code signifies a form of dementia caused by cerebrovascular disease, where the cognitive impairment is moderate in severity. Patients exhibit noticeable decline in memory, executive function, and other cognitive domains, significantly impacting daily activities. A key feature for this specific code is the presence of psychotic symptoms, such as hallucinations or delusions.

Apply this code when documentation clearly indicates a diagnosis of vascular dementia with a specified moderate severity. The patient's medical record must also explicitly state the presence of psychotic disturbances, distinguishing it from other behavioral or mood symptoms. This code is appropriate when the dementia is directly attributable to cerebrovascular events.

• Ensure documentation specifies "moderate" severity and explicitly mentions "psychotic disturbance" to support this granular code.
• Differentiate from F01.C2 (severe) or F01.A2 (mild) based on the physician's assessment of cognitive impairment.
• Do not use if the psychotic symptoms are due to another underlying condition or medication side effect rather than the dementia itself.
