Unspecified mental disorder

There are several circumstances in which it may be appropriate to assign this code: (1) for a specific mental disorder not included in the DSM-IV Classification, (2) when none of the available Not Otherwise Specified categories is appropriate, or (3) when it is judged that a non-psychotic mental disorder is present but there is not enough information available to diagnose one of the categories provided in the classification. In some cases, the diagnosis can be changed to a specific disorder after more information is obtained.
