CMSSource: CMS FY 2026 ICD-10-CM dataset · Effective Oct 1, 2025 – Sep 30, 2026

G47.39 is a billable ICD-10-CM diagnosis code for other sleep apnea. It is valid on HIPAA claims for fiscal year 2026 (October 1, 2025 through September 30, 2026) and groups to MS-DRG 154 through 156. Coders also document this condition as acquired central alveolar hypoventilation. In AHRQ's Clinical Classifications Software (CCSR), this diagnosis falls under Sleep wake disorders.

Clinical InformationClinical

  • 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.

Patient EducationClinical

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.

Questions About G47.39Overview

Is G47.39 (Sleep apnea) a billable code?

Yes. This is a billable ICD-10-CM code, specific enough to report other sleep apnea on HIPAA-covered claims from October 1, 2025 through September 30, 2026.

What MS-DRG does G47.39 group to?

When other sleep apnea is the principal diagnosis on an inpatient stay, it groups to MS-DRG 154, 155, 156, with relative weights from 0.6911 to 1.5635 depending on complications. Higher weights mean higher Medicare reimbursement.

What is the ICD-9 equivalent of G47.39?

Under the General Equivalence Mappings, other sleep apnea converts to ICD-9-CM 327.29 (organic sleep apnea NEC). The mapping is approximate, so confirm the match fits the documentation.

Footnotes

[1] Chronic - a chronic condition code indicates a condition lasting 12 months or longer and its effect on the patient based on one or both of the following criteria:

  • The condition results in the need for ongoing intervention with medical products,treatment, services, and special equipment
  • The condition places limitations on self-care, independent living, and social interactions.
