Circadian rhythm sleep disorder, jet lag type

This code identifies a temporary sleep-wake cycle disruption resulting from rapid travel across multiple time zones. Individuals experience symptoms such as insomnia, excessive daytime sleepiness, and impaired performance due to the mismatch between their internal circadian clock and the new local time.

Apply this code when documentation clearly indicates a patient's sleep disturbance is directly attributable to recent transmeridian travel. Supporting documentation should include a history of recent travel across at least two time zones and presenting symptoms consistent with jet lag, such as fatigue, difficulty initiating or maintaining sleep, or gastrointestinal upset.

• Ensure the documentation explicitly links the sleep disturbance to recent time zone changes, not other sleep disorders.
• Do not use this code for general travel fatigue or sleep issues unrelated to circadian rhythm disruption.
• Consider co-reporting with codes for specific symptoms if they are significant and require separate management.
