as many are aware the Diagnostic label DDNOS has been eliminated from the DSM. DDNOS is now called ...

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.
