This category applies to presentations in which symptoms characteristic of a tic disorder that cause clinically significant distress or impairment in social, occupational, or other im- portant areas of functioning predominate but do not meet the full criteria for a tic disorder or any of the disorders in the neurodevelopmental disorders diagnostic class. The other specified tic disorder category is used in situations in which the clinician chooses to com- municate the specific reason that the presentation does not meet the criteria for a tic disor- der or any specific neurodevelopmental disorder. This is done by recording “other specified tic disorder” followed by the specific reason (e.g., ‘With onset after age 18 years").
307.20 (F959)
This category applies to presentations in which symptoms characteristic of a tic disorder that cause clinically significant distress or impairment in social, occupational, or other im- portant areas of functioning predominate but do not meet the full criteria for a tic disorder or for any of the disorders in the neurodevelopmental disorders diagnostic class. The un- specified tic disorder category is used in situations in which the clinician chooses not to specify the reason that the criteria are not met for a tic disorder or for a specific neurode- velopmental disorder, and includes presentations in which there is insufficient information to make a more specific diagnosis.
315.8 (F88)
This category applies to presentations in which symptoms characteristic of a neurodevel- opmental disorder that cause 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 neurodevelopmental disorders diagnostic class. The other specified neurodevelopmental 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 neurode- velopmental disorder. This is done by recording “other specified neurodevelopmental dis- order" followed by the specific reason (e.g., “neurodevelopmental disorder associated with prenatal alcohol exposure").
An example of a presentation that can be specified using the “other specified" desig- nation is the following:
Neurodevelopmental disorder associated with prenatal alcohol exposure: Neu- rodevelopmental disorder associated with prenatal alcohol exposure is characterized by a range of developmental disabilities following exposure to alcohol in utero.
315.9 (F89)
This category applies to presentations in which symptoms characteristic of a neurodevel- opmental disorder that cause 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 neurodevelopmental disorders diagnostic class. The unspecified neurodevelopmental dis- order category is used in situations in which the clinician chooses not to specify the reason that the criteria are not met for a specific neurodevelopmental disorder, and includes pre- sentations in which there is insufficient information to make a more specific diagnosis (e.g., in emergency room settings).
