Code Classification

Tabular List of Diseases and Injuries

The Tabular List of Diseases and Injuries is a list of ICD-10 codes, organized "head to toe" into chapters and sections with guidance for inclusions, exclusions, descriptions and more. The following references are applicable to the code G47.33:


Inclusion Terms

Inclusion Terms
These terms are the conditions for which that code is to be used. The terms may be synonyms of the code title, or, in the case of "other specified" codes, the terms are a list of the various conditions assigned to that code. The inclusion terms are not necessarily exhaustive. Additional terms found only in the Alphabetic Index may also be assigned to a code.

Type 1 Excludes

Type 1 Excludes
A type 1 excludes note is a pure excludes note. It means "NOT CODED HERE!" An Excludes1 note indicates that the code excluded should never be used at the same time as the code above the Excludes1 note. An Excludes1 is used when two conditions cannot occur together, such as a congenital form versus an acquired form of the same condition.

Index to Diseases and Injuries

Information for Patients


Sleep Apnea

Also called: Sleep-disordered breathing

Sleep apnea is a common disorder that causes your breathing to stop or get very shallow. Breathing pauses can last from a few seconds to minutes. They may occur 30 times or more an hour.

The most common type is obstructive sleep apnea. It causes your airway to collapse or become blocked during sleep. Normal breathing starts again with a snort or choking sound. People with sleep apnea often snore loudly. However, not everyone who snores has sleep apnea.

You are more at risk for sleep apnea if you are overweight, male, or have a family history or small airways. Children with enlarged tonsils or adenoids may also get it.

Doctors diagnose sleep apnea based on medical and family histories, a physical exam, and sleep study results.

When your sleep is interrupted throughout the night, you can be drowsy during the day. People with sleep apnea are at higher risk for car crashes, work-related accidents, and other medical problems. If you have it, it is important to get treatment. Lifestyle changes, mouthpieces, surgery, and breathing devices can treat sleep apnea in many people.

Obstructive sleep apnea Obstructive sleep apnea is a condition in which individuals experience pauses in breathing (apnea) during sleep, which are associated with partial or complete closure of the throat (pper airway). Complete closure can lead to apnea while partial closure allows breathing but decrease the intake of oxygen (hypopnea).Individuals with obstructive sleep apnea may experience interrupted sleep with frequent awakenings and loud snoring. Repeated pauses in breathing lead to episodes of lower-than-normal oxygen levels (hypoxemia) and a buildup of carbon dioxide (hypercapnia) in the bloodstream. Interrupted and poor quality sleep can lead to daytime sleepiness and fatigue, impaired attention and memory, headaches, depression, and sexual dysfunction. Daytime sleepiness leads to a higher risk of motor vehicle accidents in individuals with obstructive sleep apnea. Obstructive sleep apnea is also associated with an increased risk of developing insulin resistance, which is an inability to regulate blood sugar levels effectively; high blood pressure (hypertension); heart disease; and stroke.
