ICD-10 Code F63.8 – Other impulse disorders (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code F63.8 – Other impulse disorders
What it is
F63.8 identifies other specified impulse disorders, meaning a documented impulse-control problem that does not fit a more specific ICD-10 category. Use the code when the record clearly supports an impulse disorder but names a different or unspecified type.
Clinical signs
Clinical features vary; refer to documentation. Commonly, records describe repeated failure to resist urges or behaviors that are harmful, distressing, or disruptive, with impaired control despite negative consequences.
When to use this code
Use F63.8 when the clinician documents an impulse disorder that is not classified elsewhere, such as a specified compulsive or repetitive behavior pattern. It also fits when the note supports an impulse-control diagnosis but does not match a more specific code. Check documentation if the exact disorder name is unclear.
Do not use for
Do not use this code for conditions with a more specific ICD-10 diagnosis, or when the record only describes a symptom without a diagnosed impulse disorder. Check documentation for the exact clinical term.
Coding tip
Code the most specific documented impulse disorder first; use F63.8 only when no other impulse-disorder code fits.
