290 Trauma- and Stressor-Related Disorders
Unspecified Trauma- and
Stressor-Related Disorder
309.9 (F43.9)
This category applies to presentations in which symptoms characteristic of a trauma- and
stressor-related disorder that cause clinically significant distress or impairment in social, oc-
cupational, or other important areas of functioning predominate but do not meet the full cri-
teria for any of the disorders in the trauma- and stressor-related disorders diagnostic class.
The unspecified trauma- or stressor-related disord er category is used in  situations in which
the clinician chooses not to specify the reason that the criteria are not met for a specific
trauma- and stressor-related disorder, and includes  presentations in which there is insuffi-
cient information to make a more specific diagnosis (e.g., in emergency room settings).
