the clinician chooses not to specify the reason that the criteria are not met for hypersom-
nolence disorder or a specific sleep-wake disorder, and includes presentations in which
there is insufficient information to make a more specific diagnosis.
Other Specified Sleep-Wake Disorder
780.59 (G47.8)
This category applies to presentations in which symptoms characteristic of a sleep-wake
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 sleep-wake disorders diagnostic class and do not qualify for a diagno-
sis of other specified insomnia disorder or  other specified hypersomnolence disorder. The
other specified sleep-wake 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 sleep-wake disorder . This is done by recording “other specified
sleep-wake disorder” followed by the specific reason (e.g., “repeated arousals during rapid
eye movement sleep without polysomnography or history of Parkinson’s disease or other
synucleinopathy”).
