Code Description

ICD-10 F51.02 is a billable code used to indicate a diagnosis of adjustment insomnia.

Key Diagnostic Point:

Adjustment insomnia is a sleep disorder characterized by difficulty in initiating or maintaining sleep, which occurs in response to identifiable stressors or changes in the individual's life. This condition is often temporary and can arise from various life events such as job loss, relationship issues, or significant life transitions. Patients may experience symptoms such as difficulty falling asleep, frequent awakenings during the night, and early morning awakenings. The insomnia is not due to another sleep disorder, substance use, or a medical condition. It is essential to differentiate adjustment insomnia from chronic insomnia and other sleep disorders, as the treatment approach may vary. Cognitive-behavioral therapy (CBT) is often recommended, along with lifestyle modifications to improve sleep hygiene. Understanding the psychological and environmental factors contributing to the insomnia is crucial for effective management. The condition can significantly impact daily functioning, mood, and overall quality of life, making timely diagnosis and intervention important.
