• The ICD-10-CM version G47.33 is used to diagnose Obstructive sleep apnea (adult) (pediatric) classified in America. The code for the corresponding diagnosis may differ internationally.

• It’s under the umbrella category of “Diseases of the nervous system,” specifically “Sleep disorders.”
• Practitioners can use this code when the patient’s sleep apnea is due to an upper airway obstruction. 
• P28.3, or Obstructive sleep apnea of newborn, is this code’s type 1 excludes note.
• This code is valid until the end of fiscal year 2023.

Clinical Information

• Obstructive sleep apnea (OSA) is a breathing disorder wherein a patient’s breathing stops and starts multiple times while sleeping. Compared to hypopneas, wherein the patient’s breathing is reduced, apneas are when the patient’s breathing stops altogether. 
• Obstructive sleep apnea is considered the most common type of sleep apnea. 
• There are three types of obstructive sleep apnea: severe obstructive sleep apnea, moderate obstructive sleep apnea, and mild obstructive sleep apnea. A patient’s OSA is categorized based on their apnea-hypopnea index (AHI) score. 
• The cause of obstructive sleep apnea, which also differentiates it from other kinds of sleep apnea, is the relaxation of throat muscles, resulting in narrowed airway to airway obstruction. 
• Common signs of obstructive sleep apnea include loud snoring, gasping or choking when waking up abruptly, headaches in the morning, excessively falling asleep during the day, and apnea episodes wherein others notice that the patient’s breathing stops followed by snoring. Patients should visit a doctor when they exhibit snoring, choking, or paused breathing symptoms. 
• Those at high risk of developing obstructive sleep apnea are people who smoke, are overweight/obese, postmenopausal, have hypertension or high blood pressure, have chronic lung disease, have chronic nasal congestion, and have a history of family members with OSA. 
• Most of the time, people with OSA aren’t aware that they must be diagnosed and treated for the disorder. If left untreated, patients may develop health problems such as increased blood pressure, cardiovascular problems, and daytime sleepiness. 
• To diagnose OSA, patients will be asked for their medical history and undergo physical examinations and polysomnography tests. 
• There are multiple treatment methods for obstructive sleep apnea. Among them are continuous positive airway pressure (CPAP) and bilevel positive airway pressure (BPAP). Others are sleeping or lifestyle changes such as losing weight, sleeping on one’s side, avoiding alcohol, and using sedatives. In extreme cases, patients may undergo surgery to treat their OSA.
