Cornelia de Lange syndrome, and Smith-Magenis syndrome. When stereotypic move- ment disorder co-occurs with another medical condition, both should be coded.
Note: A tic is a sudden, rapid, recurrent, nonrhythmic motor movement or vocalization.
Tourette’s Disorder 307.23 (F952)
A. Both multiple motor and one or more vocal tics have been present at some time during the illness, although not necessarily concurrently.
B. The tics may wax and wane in frequency but have persisted for more than 1 year since first tic onset.
C. Onset is before age 18 years.
D. The disturbance is not attributable to the physiological effects of a substance (e.g., co- caine) or another medical condition (e.g., Huntington‘s disease, postviral encephalitis).
Persistent (Chronic) Motor or Vocal Tic Disorder 307.22 (F95.1)
A. Single or multiple motor or vocal tics have been present during the illness, but not both motor and vocal.
B. The tics may wax and wane in frequency but have persisted for more than 1 year since first tic onset.
C. Onset is before age 18 years.
D. The disturbance is not attributable to the physiological effects of a substance (e.g., co- caine) or another medical condition (e.g., Huntington's disease, postviral encephalitis).
E. Criteria have never been met for Tourette’s disorder.
Specify it:
Provisional Tic Disorder 307.21 (F95.0) . Single or multiple motor and/or vocal tics.
. The tics have been present for less than 1 year since first tic onset.
. Onset is before age 18 years.
. The disturbance is not attributable to the physiological effects of a substance (e.g., co- caine) or another medical condition (e.g., Huntington's disease, postviral encephalitis).
. Criteria have never been met for Tourette‘s disorder or persistent (chronic) motor or vocal tic disorder.
The ”motor tics only” or ”vocal tics only” specifier is only required for persistent (chronic) motor or vocal tic disorder.
Tic disorders comprise four diagnostic categories: Tourette’s disorder, persistent (chronic) motor or vocal tic disorder, provisional tic disorder, and the other specified and unspecified tic disorders. Diagnosis for any tic disorder is based on the presence of motor and / or vocal tics (Criterion A), duration of tic symptoms (Criterion B), age at onset (Criterion C), and ab- sence of any known cause such as another medical condition or substance use (Criterion D).
The tic disorders are hierarchical in order (i.e., Tourette’s disorder, followed by persistent [Chronic] motor or vocal tic disorder, followed by provisional tic disorder, followed by the other specified and unspecified tic disorders), such that once a tic disorder at one level of the hierarchy is diagnosed, a lower hierarchy diagnosis cannot be made (Criterion E).
Tics are sudden, rapid, recurrent, nonrhythmic motor movements or vocalizations. An individual may have various tic symptoms over time, but at any point in time, the tic rep- ertoire recurs in a characteristic fashion. Although tics can include almost any muscle group or vocalization, certain tic symptoms, such as eye blinking or throat clearing, are common across patient populations. Tics are generally experienced as involuntary but can be vol- untarily suppressed for varying lengths of time.
