Tourette's disorder

This code signifies a chronic neurological condition characterized by multiple motor tics and at least one vocal tic, which have been present for more than one year. These tics are involuntary, sudden, rapid, recurrent, nonrhythmic movements or vocalizations that wax and wane in severity and frequency. The disorder typically has an onset before adulthood and can significantly impact daily functioning.

Apply this code when documentation clearly indicates a diagnosis of Tourette's disorder, meeting the diagnostic criteria for both multiple motor and at least one vocal tic persisting for over a year. Supporting documentation should include a detailed history of tic onset, type, frequency, and duration, as well as the absence of other medical conditions that could explain the tics. This code is appropriate for initial diagnoses, follow-up visits, and management of the condition.

• Ensure the documentation specifies both motor and vocal tics, and that they have been present for at least one year.
• Differentiate from other tic disorders (e.g., transient tic disorder, chronic motor or vocal tic disorder) which have distinct diagnostic criteria.
• Code any co-occurring conditions, such as ADHD or OCD, separately as these are frequently seen with Tourette's disorder.
