ICD-10 Code G47.25 – Circadian rhythm sleep disorder, jet lag type (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code G47.25 – Circadian rhythm sleep disorder, jet lag type
What it is
G47.25 identifies a circadian rhythm sleep disorder caused by rapid travel across time zones. It reflects a temporary mismatch between the body clock and local time, leading to sleep disruption.
Clinical signs
Common findings include insomnia at the intended bedtime, excessive sleepiness during the day, and difficulty adjusting to the new sleep schedule. Clinical features vary; refer to documentation.
When to use this code
Use this code when the provider documents jet lag as the cause of the sleep disturbance. It fits travelers with sleep-wake disruption after crossing time zones, not general fatigue from travel. Confirm the diagnosis is specifically circadian rhythm sleep disorder, jet lag type.
Do not use for
Do not use it for nonspecific insomnia, ordinary tiredness, or sleep problems without documented time-zone travel. Check documentation if the record does not clearly link symptoms to jet lag.
Coding tip
Code G47.25 only when the chart ties symptoms to recent crossing of time zones and the provider names jet lag type.
