ICD10 code of Tourette Syndrome and ICD9 code

The primary medical classification for Tourette Syndrome is ICD-10 code F95.2, which specifically denotes "Tourette's disorder." In the legacy ICD-9-CM classification system, Tourette Syndrome was categorized under code 307.23.

What exactly is Tourette Syndrome?

Tourette Syndrome is a neurodevelopmental disorder characterized by the presence of multiple motor tics and at least one vocal (phonic) tic. These tics must persist for more than one year, although they do not need to be concurrent. While many people associate the condition with coprolalia (the involuntary utterance of obscene words), this occurs in only about 10% to 15% of individuals with Tourette Syndrome, making it a relatively rare manifestation of the disorder.

How is Tourette Syndrome diagnosed?

There is no single blood test or brain scan used to diagnose Tourette Syndrome. Instead, clinicians rely on the diagnostic criteria established in the DSM-5 (Diagnostic and Statistical Manual of Mental Disorders). The diagnosis is clinical, meaning it is based on a thorough observation of symptoms and a detailed patient history. Physicians must rule out other neurological conditions or medication side effects that could mimic tics. For our 387 community members at DiseaseMaps.org, the diagnostic journey often involves consultations with neurologists, pediatricians, or psychiatrists who specialize in movement disorders.

What are the common comorbidities of Tourette Syndrome?

It is clinically significant to note that Tourette Syndrome rarely occurs in isolation. A large percentage of patients experience co-occurring conditions that often have a greater impact on quality of life than the tics themselves. Common comorbidities include:

• Attention Deficit Hyperactivity Disorder (ADHD): Present in approximately 60% of individuals with Tourette Syndrome.


• Obsessive-Compulsive Disorder (OCD): Observed in about 30% to 40% of cases.


• Anxiety Disorders: Frequently reported by both children and adults.


• Learning Disabilities: Including challenges with executive function and processing speed.


• Sleep Disorders: Often exacerbated by the physical demands of chronic ticcing.

Is Tourette Syndrome hereditary?

Research suggests a strong genetic component to Tourette Syndrome, though the inheritance pattern is complex and likely polygenic, meaning it involves multiple genes rather than a single mutation. Studies of twins and families indicate that if one person has the condition, the risk for first-degree relatives is significantly higher than in the general population. However, the expression of the disorder can vary widely, even within the same family; one relative might have severe tics, while another might show only mild behaviors or OCD symptoms.

Next steps

• Consult a movement disorder specialist or a pediatric neurologist to confirm your diagnosis and rule out secondary causes.


• Connect with the 387 other members on DiseaseMaps.org to share coping strategies and insights into living with the condition.


• Seek a comprehensive evaluation for common comorbidities like ADHD and OCD, as these often require targeted therapeutic interventions.


• Consider behavioral therapies, such as Comprehensive Behavioral Intervention for Tics (CBIT), which is considered a first-line non-pharmacological treatment.
