ICD-10 Code G47.39 – Other sleep apnea (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code G47.39 – Other sleep apnea
What it is
G47.39 identifies sleep apnea that does not fit obstructive, central, or unspecified categories. Use it when the record clearly describes another specific sleep apnea type.
Clinical signs
Clinical features vary; refer to documentation. Commonly, records note repeated breathing interruptions during sleep, snoring, or daytime sleepiness, but the exact pattern should support the documented subtype.
When to use this code
Use this code when the provider documents a distinct sleep apnea diagnosis other than the common named categories. It may apply when testing or specialist notes identify an alternate form, but the chart does not support a different sleep apnea code.
If the documentation is vague or only says “sleep apnea,” check documentation before coding. The record should support why the condition is classified as “other” rather than obstructive, central, or unspecified.
Do not use for
Do not use G47.39 for obstructive sleep apnea, central sleep apnea, or unspecified sleep apnea. If the provider has not identified a specific alternate type, choose the code that best matches the documentation.
Coding tip
Confirm the documented sleep apnea subtype in the assessment, sleep study report, or specialist note before assigning G47.39.
