422 Sleep-Wake Disorders
Unspecified Sleep-Wake Disorder
780.59 (G47.9)
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 di agnostic class and do not qualify for a diagno-
sis of unspecified insomnia disorder or unspecified hypersomnolence disorder. The un-
specified sleep-wake 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 sleep-wake disorder,
and includes presentations in which there is insufficient information to make a more spe-
cific diagnosis.
