ICD-10 Code G47.37 – Central sleep apnea in conditions classified elsewhere (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code G47.37 – Central sleep apnea in conditions classified elsewhere
What it is
This code identifies central sleep apnea when it occurs because of another underlying condition. Unlike obstructive sleep apnea, the problem is reduced or absent breathing effort during sleep.
Clinical signs
Common findings include repeated pauses in breathing during sleep, fragmented sleep, and daytime sleepiness. Clinical features vary; refer to documentation and sleep study results when available.
When to use this code
Use G47.37 when the record states central sleep apnea is secondary to another documented condition, such as a neurologic or medical disorder. You should also use it when the provider clearly links the apnea to an underlying cause. If the cause is not documented, check documentation before coding.
Do not use for
Do not use this code for obstructive sleep apnea or for central sleep apnea without a documented underlying condition. Check documentation if the chart only says “sleep apnea” or gives an unspecified type.
Coding tip
Confirm both the central sleep apnea diagnosis and the associated condition in the medical record before assigning this code.
