Circadian rhythm sleep disorders
ICD-10 G47.2 is a billable code used to indicate a diagnosis of circadian rhythm sleep disorders.
Circadian rhythm sleep disorders (CRSD) are a group of sleep disorders that result from a misalignment between an individual's internal biological clock and the external environment, particularly the light-dark cycle. These disorders can lead to significant sleep disturbances, including insomnia, excessive daytime sleepiness, and impaired functioning. Common types of CRSD include delayed sleep phase disorder, advanced sleep phase disorder, irregular sleep-wake rhythm, and non-24-hour sleep-wake disorder. Patients may experience difficulty falling asleep or waking up at desired times, which can affect their daily activities and overall health. The diagnosis typically involves a thorough clinical history, sleep diaries, and sometimes actigraphy or polysomnography to assess sleep patterns. Treatment may include behavioral interventions, light therapy, and, in some cases, pharmacotherapy to help realign the circadian rhythm with the external environment.
