Other acute reactions to stress

This code represents an acute, time-limited psychological response to an identifiable psychosocial stressor that is not severe enough to meet criteria for a more specific anxiety disorder or adjustment disorder. Symptoms typically include emotional distress, anxiety, or behavioral disturbances that resolve within a short period after the stressor is removed or the individual adapts.

Use this code for transient stress reactions that do not meet the diagnostic criteria for adjustment disorder, PTSD, or other specified anxiety disorders. Documentation should clearly indicate an acute onset of symptoms directly following a stressor, with a duration typically less than one month, and resolution without significant functional impairment.

• Differentiate from adjustment disorders (309.xx) which imply a more prolonged or severe reaction with functional impairment.
• Avoid using for normal grief reactions or expected responses to significant life events unless symptoms are disproportionate and cause distress.
• Ensure documentation specifies the acute nature and resolution of symptoms to support this diagnosis over chronic stress or anxiety.
