What This Code Means

This code describes a condition where a person has difficulty controlling sudden urges or impulses to do something, but the specific type of impulse disorder has not been identified or documented. It's used when a patient struggles with impulsive behavior that causes problems in their life, but the exact nature of the impulse problem isn't specified.

Coding Tips

• •Use this code only when the specific impulse disorder (such as pyromania, kleptomania, or trichotillomania) cannot be determined from the medical record; always attempt to document the specific type of impulse disorder if possible
• •Review the clinical documentation carefully to see if the impulse disorder can be more specifically classified, as using the unspecified code may result in lower reimbursement and less precise medical records

Clinical Significance

Unspecified impulse disorder is used when the provider documents an impulse control disorder but does not specify the type. While this code is clinically acceptable, it provides less information for care management. Impulse control disorders as a group are associated with significant psychosocial dysfunction and comorbid psychiatric conditions requiring ongoing treatment.

Documentation Requirements

• ✓Provider documentation of an impulse control disorder diagnosis
• ✓Evidence of recurrent failure to resist impulses leading to harmful acts
• ✓Functional impairment documented in social, occupational, or personal domains
• ✓Query opportunity — attempt to obtain specificity from the provider to use a more precise code
• ✓Treatment plan addressing the impulse control condition
