ICD-10 Code F63 – Impulse disorders (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code F63 – Impulse disorders
What it is
F63 covers impulse disorders, a group of conditions marked by repeated inability to resist impulses or urges. The behavior may be harmful, distressing, or disruptive.
Clinical signs
Clinical features vary; refer to documentation. Commonly, you may see recurrent impulsive acts, tension before the act, and relief or gratification afterward. Diagnosis depends on the documented disorder.
When to use this code
Use F63 when the provider documents an impulse disorder and does not specify a more precise diagnosis. It may apply when the record describes repeated, uncontrolled impulsive behavior that is clinically recognized as an impulse-control condition.
Check documentation for the exact subtype, because some impulse-related behaviors have their own specific codes. Code the documented condition rather than a symptom alone.
Do not use for
Do not use F63 for ordinary impulsive behavior without a diagnosed disorder. Also avoid it when the chart identifies a different mental health condition or a more specific code.
Coding tip
Look for the exact provider term and code the most specific impulse disorder documented.
