Depressive Disorder Not Otherwise Specified

Depressive Disorder Not Otherwise Specified (DD-NOS) is designated by the code 311 in the DSM-IV for depressive disorders that are impairing but do not fit any the officially specified diagnoses. According to the DSM-IV, DD-NOS encompasses "any depressive disorder that does not meet the criteria for a specific disorder."

Examples of disorders in this category include those sometimes described as Minor Depressive Disorder and Recurrent Brief Depressive Disorder.

Concerns
Accurately assessing for a specific Depressive Disorder diagnosis requires an expenditure of time that is deemed unreasonable for most primary care physicians. For this reason, physicians often use this code as a proxy for a more thorough diagnosis. There is concern that this may lead to a "waste basket" mindset for certain disorders.
