yes some countries still use the diagnosis label ....not otherwise specified (NOS) but here in the USA there is no labeling of NOS for dissociative disorders..

it has been changed over to the new diagnostic labeling system where what .......used..... to be called Dissociative Disorders not otherwise specified (DDNOS) is now two different diagnostic labels......

OSDD (other Specified Dissociative Disorder)

Other Specified Dissociative Disorder 300.15 (F44.89)

This category applies to presentations in which symptoms characteristic of a dissociative disorder that causes clinically significant distress or impairment in social, occupational or other important areas of functioning predominate but do not meet the full criteria for any of the disorders in the dissociative disorders diagnostic class. The Other Specified Dissociative Disorder category is used in situations in which the clinician chooses to communicate the specific reason that the presentation does not meet the criteria for any specific dissociative disorder. This is done by recording "Other Specified Dissociative Disorder" followed by the specific reason (e.g. "Dissociative Trance")

Examples of presentations that can be specified using the "other specified" designation include the following:

1. Chronic and recurrent syndromes of mixed dissociative symptoms: This category includes identity disturbance associated with less-than-marked discontinuities in sense of self and agency, or alterations of identity or episodes of possession in an individual who reports no dissociative amnesia.

2. Identity disturbance due to prolonged and intensive coercive persuasion: individuals who have been subjected to intensive coercive persuasion (e.g. brainwashing, thought reform, indoctrination while captive torture, long term political imprisonment, recruitment by sects/cults or by terror organizations) may present with prolonged changes in or conscious questioning of, their identity.

3. Acute Dissociative reactions to stressful events: this category is for acute transient conditions that typically last less than 1 month and sometimes only a few hours or days. These conditions are characterized by constriction of consciousness, depersonalization, derealization,perceptual disturbances (e.g. time slowing, macropsia) micro-amnesias, transient stupor; and or alterations in sensory-motor functioning (e.g. analgesia, paralysis)

4 Dissociative Trance: This condition is characterized by an acute narrowing or complete loss of awareness of immediate surroundings that manifests as profound unresponsiveness or insensitivity to environmental stimuli. the unresponsiveness may be accompanied by minor stereotyped behaviors (e.g. finger movements) of which the individual is unaware and/or that he or she can not control, as well as transient paralysis or loss of consciousness. The dissociative trance is not a normal part of a broadly accepted collective cultural or religious practice.

and UDD (unspecified Dissociative Disorder)........

Unspecified Dissociative Disorder 300.15 (F44.9)

under this diagnostic label the DSM 5 states....

this category applies to presentations in which symptoms characteristic of dissociative disorder that cause clinically significant distress or impairment in social, occupational or other important areas of functioning predominate but do not meet the full criteria for any of the disorders in the dissociative disorders diagnostic class. the Unspecified dissociative disorder category is used in situations in which the clinician chooses not to specify the reason that the criteria are not met for a specific dissociative disorder, and includes presentations for which there is insignificant information to make a more specific diagnosis (e.g. in emergency room settings)

the DSM does not go into any further detail like it did with DID, depersonalization/derealization disorder and dissociative amnesia.
