Idiopathic sleep related nonobstructive alveolar hypoventilation
ICD-10 G47.34 is a billable code used to indicate a diagnosis of idiopathic sleep related nonobstructive alveolar hypoventilation.
Idiopathic sleep-related nonobstructive alveolar hypoventilation is a condition characterized by inadequate ventilation during sleep, leading to elevated carbon dioxide levels and decreased oxygen saturation without any identifiable obstructive cause. Patients typically present with excessive daytime sleepiness, fatigue, and cognitive impairment. Unlike obstructive sleep apnea, which is caused by physical blockage of the airway, this condition arises from a failure of the respiratory system to adequately ventilate the alveoli during sleep. Diagnosis often involves polysomnography, which reveals hypoventilation patterns, and may require arterial blood gas analysis to confirm hypercapnia (elevated carbon dioxide levels) during sleep. The idiopathic nature of this condition means that no specific underlying pathology can be identified, making management challenging and often requiring a multidisciplinary approach, including lifestyle modifications, respiratory support, and continuous positive airway pressure (CPAP) therapy in some cases.

Ensure the sleep study is interpreted by a qualified sleep specialist.
The primary cause is unknown, hence the term 'idiopathic.' It is characterized by inadequate ventilation during sleep without any identifiable obstructive cause.
