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 of 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." In the DSM-5, it is called unspecified depressive disorder.
Examples of disorders in this category include those sometimes described as minor depressive disorder and recurrent brief depression.
'Depression' refers to a spectrum of disturbances in mood that vary from mild to severe and from short periods to constant illness. A Depressive Disorder Not Otherwise Specified is diagnosed if a patients symptoms fail to meet the criteria more common depressive disorders such as Major Depressive Disorder or Dysthymia. Although Depressive Disorder NOS shares similar symptoms to Dysthymia, Dysthymia is classified by a period of at least 2 years of constantly recurring depressed mood, where as Depressive Disorder NOS is classified by much shorter periods of depressed moods.
For most people who suffer the condition, their life will be significantly affected. Depressive Disorder NOS can make many aspects of a person's daily life difficult to manage, inhibiting their ability to enjoy the things that used to make them happy. Sufferers of the disorder tend to isolate themselves from their friends and families; they tend to lose interest in some activities, experience behavioural changes and sleeping disorders. Some sufferers also experience suicidal tendencies or suicide attempts. In addition to having these symptoms, a diagnosis of Depressive Disorder NOS will only be made if the symptoms cause significant distress or impairment in social, occupational, or other important areas of functioning. For the diagnosis to be accurate, a psychiatrist is required to spend extensive time with the patient.
Symptoms of the disorder may arise due to several reasons. These include:
- Distress due to medical conditions
- Environmental effects and situations
However the effects of drugs or medication or bereavement are not classified under the diagnosis.
A person will not be diagnosed with the condition if they have or have had any of the following: a major depressive episode, manic episode, mixed episode or hypomanic episode.
A diagnosis of the disorder will look like this: "Depressive Disorder NOS 311"

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 "wastebasket" mindset for certain disorders. In addition reimbursement through Medicare may be lower for certain non specific diagnosis.
