Clinical Definition

ICD-10-CM F95.1 refers to persistent (chronic) tic disorders characterized by either motor tics or vocal tics—but not both—that persist for more than one year. Symptoms are involuntary, recurring, and typically emerge in childhood or adolescence. Diagnosis under this code excludes transient tics (F95.0) and Tourette’s disorder (F95.2), which involves both motor and vocal tics.

Included Terminology (Synonyms)

• Chronic motor tic disorder
  
• Persistent motor tic disorder
  
• Chronic vocal tic disorder
  
• Persistent vocal tic disorder
  
• Motor tic disorder – chronic
  
• Vocal tic disorder – chronic
  

Coding Instructions

Use F95.1 when all the following apply:

• Only motor or vocal tics (not both) are present
  
• Duration of symptoms exceeds 12 months
  
• Symptoms began before age 18
  
• No other medical explanation for the tics
  

✅ Billable: Yes
🚫 Do not use for transient tic disorders (F95.0)
🚫 Do not use for Tourette’s disorder (F95.2)

Diagnostic Relevance

F95.1 is commonly coded in pediatric neuropsychiatric evaluations and behavioral assessments, especially in school-aged children presenting with persistent involuntary movements or vocalizations. Proper documentation should differentiate between single-type tics (motor or vocal) and combined-type (Tourette’s) to avoid misclassification.

• DRG 092: …with CC
  
• DRG 093: …without CC/MCC
  

These classifications assist in hospital inpatient resource grouping and cost estimation.
