judgment. At times, a change in the treatment  for the other medical condition (e.g., med-
ication substitution or discontinuation) may be needed to determine whether the medica-

substance/medication-induced anxiety disorder).  If the disturbance is  attributable to both
another medical condition and substance use, bo th diagnoses (i.e., anxiety disorder due to
another medical condition and substance/me dication-induced anxi ety disorder) may be
given. When there is insufficie nt evidence to determine whether the panic or anxiety symp-
toms are attributable to a subs tance/medication or to anothe r medical condition or are pri-
mary (i.e., not attributable to either a subs tance or another medical condition), a diagnosis
of other specified or unspecified an xiety disorder wo uld be indicated.
