What it is
This code identifies moderate dementia caused by another underlying disease, with psychotic disturbance. Use it when the dementia is documented as secondary to a specific condition and psychotic features are present.
Clinical signs
Typical findings include moderate memory loss, impaired reasoning, and reduced ability to manage daily activities. Psychotic disturbance may include hallucinations, delusions, or other clearly documented psychotic symptoms; clinical features vary, refer to documentation.
When to use this code
Use this code when the provider documents dementia due to another disease and specifies the severity as moderate. The record must also show psychotic disturbance linked to the dementia. Code the underlying condition as instructed by the chart and official guidelines.
Do not use for
Do not use this code if dementia is not linked to another disease, if severity is not documented as moderate, or if psychotic disturbance is absent. Check documentation when the cause or mental status details are unclear.
Coding tip
Verify both the secondary cause and the psychotic feature in the provider note before assigning F02.B2.
