F43.29 – Adjustment disorder with other symptoms

F43.29 is the ICD-10-CM code for adjustment disorder with other symptoms, a condition characterized by emotional or behavioral symptoms that develop in response to an identifiable stressor. The symptoms cause significant distress or impairment but do not meet the criteria for another psychiatric disorder.

Adjustment disorder with mixed emotional and behavioral disturbances involves a combination of emotional symptoms (such as anxiety and depression) and behavioral disturbances (such as aggression or impulsivity) that arise in response to a stressful event. These symptoms significantly impact daily functioning and typically resolve within six months after the stressor is removed.

Acute stress reaction occurs immediately after exposure to a traumatic event and typically resolves within a few days or weeks, often involving dissociation, anxiety, and hyperarousal. In contrast, adjustment disorder develops in response to a non-traumatic stressor, with symptoms emerging within three months and lasting no longer than six months after the stressor ends.
