ICD-10-CM Code E66.2
Morbid (severe) obesity with alveolar hypoventilation
Billable Code
Billable codes are sufficient justification for admission to an acute care hospital when used a principal diagnosis.E66.2 is a billable ICD code used to specify a diagnosis of morbid (severe) obesity with alveolar hypoventilation. A 'billable code' is detailed enough to be used to specify a medical diagnosis.
The ICD code E662 is used to code Obesity hypoventilation syndrome
Obesity hypoventilation syndrome (also known as Pickwickian syndrome) is a condition in which severely overweight people fail to breathe rapidly enough or deeply enough, resulting in low blood oxygen levels and high blood carbon dioxide (CO2) levels. Many people with this condition also frequently stop breathing altogether for short periods of time during sleep (obstructive sleep apnea), resulting in many partial awakenings during the night, which leads to continual sleepiness during the day. The disease puts strain on the heart, which eventually may lead to the symptoms of heart failure, such as leg swelling and various other related symptoms. The most effective treatment is weight loss, but it is often possible to relieve the symptoms by nocturnal ventilation with positive airway pressure (CPAP) or related methods.
