Unspecified acute reaction to stress

This code represents an immediate, non-specific psychological and physiological response to an acute, overwhelming stressor. It signifies a transient disturbance in emotional, cognitive, and behavioral functioning that occurs shortly after exposure to a traumatic event. The reaction is typically severe but short-lived, resolving within hours or days.

Use this code when documentation indicates a patient is experiencing an acute stress reaction that does not meet the specific criteria for other, more defined stress-related disorders like acute stress disorder or PTSD. This code is appropriate for situations where the stressor is clearly identified, and the patient's symptoms are a direct, immediate, and transient response. Documentation should describe the stressor and the patient's acute, non-specific distress.

• Avoid using this code if the reaction persists beyond a few days or if specific diagnostic criteria for other stress disorders are met.
• Consider codes for more specific stress reactions (e.g., 308.3, Acute stress disorder) if documentation supports those diagnoses.
• Ensure the medical record clearly identifies the acute stressor and the patient's immediate, transient reaction.
