0.000What This Code Means
A behavioral disorder that begins in adolescence (typically age 10 or later) characterized by rule-breaking, aggression, and violation of others' rights.
Coding Tips
- •Document onset at or after age 10 to differentiate from childhood-onset conduct disorder
- •Note that adolescent-onset type typically has better prognosis than childhood-onset
Clinical Significance
Adolescent-onset conduct disorder is characterized by the absence of conduct disorder symptoms before age 10, with problematic behaviors emerging during adolescence. This subtype generally has a better prognosis than childhood-onset type, with lower rates of physical aggression and higher likelihood of resolution by adulthood. However, it still carries significant risks for academic failure, substance use, and legal problems during adolescence.
Documentation Requirements
- ✓Provider documentation of conduct disorder with no characteristic symptoms before age 10
- ✓Evidence of persistent pattern of behavior violating others' rights or societal norms beginning in adolescence
- ✓Documentation confirming absence of conduct symptoms in childhood (before age 10)
- ✓Assessment of contributing factors (peer influence, substance use, family dynamics)
- ✓Treatment plan appropriate for adolescent-onset presentation
