Mood disorder not otherwise specified (MD-NOS) is a mood disorder that is impairing but does not fit in with any of the other officially specified diagnoses. In the [[DSM-IV]] MD-NOS is described as "any mood disorder that does not meet the criteria for a specific disorder."{{sfn|American Psychiatric Association|2000|p={{page needed|date=October 2021}}}} MD-NOS is not used as a clinical description but as a statistical concept for filing purposes.<ref name=Kaplan>{{cite web |last=Akiskal |first=Hagop S. |url=http://www.brown.edu/Courses/BI_278/Other/Teaching%20examples/Brain%20and%20Behavior/articles/mood.pdf |title=Mood Disorders: Clinical Features |date=2 November 2004 |publisher=Kaplan & Sadock's Comprehensive Textbook of Psychiatry |access-date=21 March 2013 |url-status=live |archive-url=https://web.archive.org/web/20150610220404/http://www.brown.edu/Courses/BI_278/Other/Teaching%20examples/Brain%20and%20Behavior/articles/mood.pdf |archive-date=10 June 2015}}</ref> The diagnosis of MD-NOS does not exist in the DSM-5, however the diagnoses of unspecified depressive disorder and unspecified bipolar disorder are in the DSM-5.<ref>{{Cite book|last=Force.|first=American Psychiatric Association.

Most cases of MD-NOS represent hybrids between mood and anxiety disorders, such as [[mixed anxiety-depressive disorder]] or [[atypical depression]].<ref name = Kaplan/> An example of an instance of MD-NOS is being in minor depression frequently during various intervals, such as once every month or once in three days.{{sfn|American Psychiatric Association|2000|p={{page needed|date=October 2021}}}} There is a risk for MD-NOS not to get noticed, and for that reason not to get treated.<ref>{{cite journal |author1=Williams Daniel T. |author2=Hirsch Scott |author3=Coffey Barbara | year = 2007 | title = Mood and Anxiety Symptoms in An Adolescent with Pervasive Developmental Disorder Not Otherwise Specified and Moderate Mental Retardation| journal = Journal of Child and Adolescent Psychopharmacology | volume = 17 | issue = 5| pages = 721–726 | doi = 10.1089/cap.2007.17503 |pmid=17979592 }}</ref>
