ICD-10-CM Code G47.30

Sleep apnea, unspecified

Version 2021 Billable Code

Valid for Submission

G47.30 is a billable code used to specify a medical diagnosis of sleep apnea, unspecified. The code is valid for the fiscal year 2021 for the submission of HIPAA-covered transactions. The ICD-10-CM code G47.30 might also be used to specify conditions or terms like breathing-related sleep disorder, glaucoma and sleep apnea syndrome, hypersomnia with sleep apnea, insomnia with sleep apnea, pulmonary hypertension due to lung disease and/or hypoxia, pulmonary hypertension due to sleep-disordered breathing, etc

Short Description:Sleep apnea, unspecified

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.

The following clinical terms are approximate synonyms or lay terms that might be used to identify the correct diagnosis code:

  • Breathing-related sleep disorder
  • Glaucoma and sleep apnea syndrome
  • Hypersomnia with sleep apnea
  • Insomnia with sleep apnea
  • Pulmonary hypertension due to lung disease and/or hypoxia
  • Pulmonary hypertension due to sleep-disordered breathing
  • Sleep apnea

Clinical Information

  • SLEEP APNEA SYNDROMES-. disorders characterized by multiple cessations of respirations during sleep that induce partial arousals and interfere with the maintenance of sleep. sleep apnea syndromes are divided into central see sleep apnea central obstructive see sleep apnea obstructive and mixed central obstructive types.
  • SLEEP APNEA OBSTRUCTIVE-. a disorder characterized by recurrent apneas during sleep despite persistent respiratory efforts. it is due to upper airway obstruction. the respiratory pauses may induce hypercapnia or hypoxia. cardiac arrhythmias and elevation of systemic and pulmonary arterial pressures may occur. frequent partial arousals occur throughout sleep resulting in relative sleep deprivation and daytime tiredness. associated conditions include obesity; acromegaly; myxedema; micrognathia; myotonic dystrophy; adenotonsilar dystrophy; and neuromuscular diseases. from adams et al. principles of neurology 6th ed p395
  • SLEEP APNEA CENTRAL-. a condition associated with multiple episodes of sleep apnea which are distinguished from obstructive sleep apnea sleep apnea obstructive by the complete cessation of efforts to breathe. this disorder is associated with dysfunction of central nervous system centers that regulate respiration.

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.
