ICD-10 Code F63.89 – Other impulse disorders (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code F63.89 – Other impulse disorders
What it is
F63.89 identifies impulse-control conditions that do not fit a more specific ICD-10 diagnosis. Use it when the record describes recurrent, hard-to-resist behaviors that cause distress or impairment, but the exact disorder is not named.
Clinical signs
Clinical features vary; refer to documentation. Commonly, the record may note repeated urges, poor control over actions, and behavior that leads to social, legal, or personal problems.
When to use this code
Use F63.89 when the clinician documents an impulse disorder and no more specific code applies. It is appropriate when the note clearly supports an impulse-control problem but does not specify pyromania, kleptomania, or another defined condition. Check documentation if the diagnosis is vague.
Do not use for
Do not use this code when a specific impulse-control diagnosis is documented and a more precise code is available. Also avoid it if the behavior is better explained by another mental, neurologic, or substance-related condition.
Coding tip
Code the most specific impulse disorder documented, and query the provider if the chart only says “impulse issues” or similar wording.
