2024 ICD-10-CM Diagnosis Code G47.39

Approximate Synonyms

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

• Acquired central alveolar hypoventilation
• Central alveolar hypoventilation syndrome
• Central sleep apnea syndrome
• Finding of rate of respiration
• Mixed sleep apnea
• Obstructive sleep apnea syndrome
• Organic sleep apnea
• Organic sleep disorder
• Sleep apnea
• Sleep apnea
• Sleep-related neurogenic tachypnea
• Tachypnea

Clinical Information

• Sleep Wake Disorders

  abnormal sleep-wake schedule or pattern associated with the circadian rhythm which affect the length, timing, and/or rigidity of the sleep-wake cycle relative to the day-night cycle.

• Tachypnea

  increased respiratory rate.

• Circadian Rhythm

  the regular recurrence, in cycles of about 24 hours, of biological processes or activities, such as sensitivity to drugs or environmental and physiological stimuli.

• Respiratory Rate

  the number of times an organism breathes with the lungs (respiration) per unit time, usually per minute.

• Central Sleep Apnea Syndrome

  a broad classification of disorders which includes 6 subtypes (primary central sleep apnea, central sleep apnea due to cheyne-stokes breathing pattern, central sleep apnea due to medical condition not cheyne-stokes, central sleep apnea due to high-altitude periodic breathing, central sleep apnea due to drug or substance and primary sleep apnea of infancy) that are each characterized by interruptions in breathing while asleep. it is caused by improper signaling from the brainstem to respiratory muscles and is triggered by either hypoventilation or hyperventilation. in adults, this disorder may arise following a stroke, congestive heart failure, trauma, infection or the use of narcotic medications. it is more common in older males and may present as a co-morbid condition to obesity. clinical signs include snoring, insomnia or hypersomnia, difficulty concentrating and fatigue. recurrent episodes of hypoxia/hypoxemia have long-term detrimental effects on cardiovascular health.

• Obstructive Sleep Apnea Syndrome

  a disorder characterized by recurrent episodic disruptions of breathing during sleep. it is caused by the intermittent relaxation of pharyngeal muscles leading to the narrowing or complete blockage of the upper airway. this results in compensatory arousal from sleep to breathe again. an anatomically narrow airway from body habitus or enlarged pharyngeal structures may also predispose to obstruction. clinical presentation usually includes snoring, daytime sleepiness, difficulty concentrating and fatigue. clinical course may progress to chronic hypoxemia with cardiovascular and cerebrovascular sequelae.

Convert G47.39 to ICD-9-CM

• ICD-9-CM Code: 327.29 - Organic sleep apnea NEC
  Approximate Flag - The approximate mapping means there is not an exact match between the ICD-10 and ICD-9 codes and the mapped code is not a precise representation of the original code.

Patient Education

Sleep Apnea

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.
