Idiopathic hypersomnia with long sleep time
ICD-10 G47.11 is a billable code used to indicate a diagnosis of idiopathic hypersomnia with long sleep time.
Idiopathic hypersomnia with long sleep time is a sleep disorder characterized by excessive daytime sleepiness despite prolonged nighttime sleep. Patients typically experience prolonged sleep episodes, often exceeding 10 hours per night, and may have difficulty waking up, feeling unrefreshed even after long sleep durations. Unlike narcolepsy, individuals with idiopathic hypersomnia do not experience cataplexy or sudden sleep attacks. The etiology remains unclear, hence the term 'idiopathic.' Diagnosis often involves comprehensive sleep studies, including polysomnography, to rule out other sleep disorders such as sleep apnea. Patients may also undergo multiple sleep latency tests (MSLT) to assess their daytime sleepiness levels. Treatment options may include stimulant medications, lifestyle modifications, and behavioral therapies aimed at improving sleep hygiene. The condition can significantly impact daily functioning, leading to challenges in occupational and social settings.

Patients presenting with excessive daytime sleepiness, prolonged sleep episodes, and difficulty waking.
Ensure comprehensive documentation of sleep study findings and differentiation from other sleep disorders.
Neurological evaluations, sleep history, and response to treatment.
Patients with neurological conditions presenting with hypersomnia symptoms.
Document neurological assessments to rule out other causes of hypersomnia.
Used to diagnose sleep disorders including idiopathic hypersomnia.
Complete sleep study report and interpretation.
Sleep medicine specialists should ensure thorough documentation of findings.
The primary difference is that narcolepsy is characterized by sudden sleep attacks and cataplexy, while idiopathic hypersomnia involves prolonged sleep without these features.
