How to code Agitation
R45.1 is restlessness and agitation. Irritability and anger are R45.4, violent behavior is R45.6, and impulsiveness is R45.87.
Agitation in dementia is built into the dementia code, so R45.1 is not added. For example, F03.911 is unspecified dementia with agitation, F01.511 is vascular dementia with agitation, and F02.811 is dementia in other diseases with agitation. Agitation from delirium is F05.
