Coding note: Include the name of the other medical condition within the name of the men-
tal disorder (e.g., 293.84 [F06.4] anxiety disorder due to pheochromocytoma). The other
medical condition should be coded and listed separately immediately before the anxiety
disorder due to the medical condition (e.g., 227.0 [D35.00] pheochromocytoma; 293.84
[F06.4] anxiety disorder due to pheochromocytoma.
Diagnostic Features
The essential feature of anxiety disorder due to  another medical condition is clinically signifi-
cant anxiety that is judged to be best explaine d as a physiological effect of another medical con-
dition. Symptoms can include pr ominent anxiety symptoms or panic attacks (Criterion A).
The judgment that the symptoms are best explai ned by the associated physical condition must
be based on evidence from the history, physical  examination, or laboratory findings (Criterion
B). Additionally, it must be judged that the sy mptoms are not better accounted for by another
mental disorder, in particular, adjustment disorder, with anxiety,  in which the stressor is the
medical condition (Criterion C). In  this case, an individual with  adjustment disorder is espe-
cially distressed about the mean ing or the consequences of th e associated medical condition.
By contrast, there is often a prominent physical component to  the anxiety (e.g., shortness of
breath) when the anxiety is due to another medica l condition. The diagnosis is not made if the
anxiety symptoms occur only during the course of a delirium (Criterion D). The anxiety symp-
toms must cause clinically significant distress or impairment in  social, occupational, or other
important areas of functioning (Criterion E).
