Code Description

ICD-10 G47.29 is a billable code used to indicate a diagnosis of other circadian rhythm sleep disorder.

Key Diagnostic Point:

Circadian rhythm sleep disorders are a group of sleep disorders that disrupt the normal sleep-wake cycle, leading to difficulties in falling asleep, staying asleep, or waking up at the desired time. These disorders can result from misalignment between an individual's internal biological clock and the external environment, such as light and social cues. Common examples include shift work disorder, jet lag disorder, and delayed sleep phase disorder. Patients may experience excessive daytime sleepiness, insomnia, or both, which can significantly impair daily functioning and quality of life. Diagnosis typically involves a thorough clinical history, sleep diaries, and may include polysomnography or actigraphy to assess sleep patterns. Treatment options vary and may include lifestyle modifications, light therapy, and melatonin supplementation. Understanding the nuances of these disorders is crucial for accurate coding and effective patient management.
