F43.12 – Post-Traumatic Stress Disorder, Chronic

PTSD diagnosis requires specific criteria, including direct or indirect exposure to trauma, intrusive reactions, persistent avoidance of reminders, negative changes in mood or feelings, and marked alterations in arousal. The duration of symptoms must exceed one month, causing significant occupational or social impairment.

Effective treatment typically involves a combination of psychotherapy and medication to address mental health symptoms like anxiety, emotional disturbance, and cognitive dysfunction.

Acute PTSD (e.g., F43.11) features a shorter duration after exposure, while chronic PTSD (10 code F43.12 post-traumatic) persists beyond three months.
