Dissociative disorder not otherwise specified (DDNOS) was a mental health diagnosis for pathological dissociation that matched the DSM-IV criteria for a dissociative disorder, but did not fit the full criteria for any of the specifically identified subtypes, and the reasons why the previous diagnoses were not met are specified. The International Statistical Classification of Diseases and Related Health Problems (ICD-10) refers to the diagnosis as "Other dissociative and conversion disorders".[1] Under the fifth edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM), it is known as "Other specified dissociative disorder" (OSDD).
