Circadian rhythm sleep disorder, advanced sleep phase type
ICD-10 G47.22 is a billable code used to indicate a diagnosis of circadian rhythm sleep disorder, advanced sleep phase type.
Circadian rhythm sleep disorder, advanced sleep phase type (ASPS) is characterized by a persistent pattern of sleep and wakefulness that is significantly advanced compared to the societal norm. Individuals with ASPS typically fall asleep earlier in the evening and wake up very early in the morning, often feeling well-rested upon awakening. This condition can lead to difficulties in social and occupational functioning, as the individual's sleep schedule may not align with typical daytime activities. ASPS is often seen in older adults but can occur in younger individuals as well. The disorder is distinct from other sleep disorders such as insomnia or sleep apnea, as it primarily involves a misalignment of the internal biological clock with the external environment. Diagnosis is typically made through clinical evaluation and may be supported by sleep studies that assess sleep patterns and circadian rhythms. Treatment options may include light therapy, melatonin supplementation, and behavioral interventions aimed at gradually shifting the sleep-wake cycle.
