ICD-10 Code F43.25 – Adjustment disorder with mixed disturbance of emotions and conduct (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code F43.25 – Adjustment disorder with mixed disturbance of emotions and conduct
What it is
F43.25 identifies an adjustment disorder where a clear stressor leads to both emotional symptoms and behavior problems. Use it when the reaction is out of proportion to the stressor and does not meet criteria for another disorder.
Clinical signs
Typical findings include anxiety, depressed mood, irritability, or worry, along with conduct changes such as acting out, defiance, or rule-breaking. Clinical features vary; refer to documentation.
When to use this code
Use this code when the record documents a recent stressor and a mixed emotional and conduct response, such as school, family, work, or relationship disruption. You should see evidence that the symptoms caused distress or impaired functioning. Check documentation if the provider does not clearly link the reaction to the stressor.
Do not use for
Do not use F43.25 if the chart supports a different primary mental disorder, such as a mood, anxiety, or conduct disorder. Do not assign it for normal stress reactions without documented impairment.
Coding tip
Confirm both components are documented: emotional disturbance and conduct disturbance tied to the same stressor.
