Adjustment insomnia

This code represents a sleep disturbance characterized by difficulty initiating or maintaining sleep, or nonrestorative sleep, directly attributable to an identifiable stressor or significant life event. The insomnia symptoms typically begin within three months of the stressor onset and resolve once the stressor is removed or the individual adapts to it. It is a transient condition, not a chronic sleep disorder.

Use this code when documentation clearly links insomnia symptoms to a specific psychosocial stressor, such as job loss, relationship issues, bereavement, or significant life changes. The patient's sleep disturbance should not be better explained by another mental disorder, substance use, or a general medical condition. The symptoms must cause clinically significant distress or impairment in social, occupational, or other important areas of functioning.

• Ensure documentation specifies a clear precipitating stressor and the transient nature of the insomnia.
• Differentiate from chronic insomnia (G47.00-G47.09) which lacks a direct, recent stressor and is long-standing.
• Do not code if the insomnia is a symptom of another primary mental health disorder (e.g., major depressive disorder, anxiety disorder).
