ICD-10 Code G47.3 – Sleep apnea (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code G47.3 – Sleep apnea
What it is
G47.3 identifies sleep apnea, a disorder marked by repeated pauses or reductions in breathing during sleep. It is used when the record documents sleep apnea without a more specific subtype.
Clinical signs
Common features include loud snoring, witnessed breathing pauses, and restless sleep. Daytime sleepiness, morning headaches, and nonrestorative sleep may also be documented; clinical features vary, refer to documentation.
When to use this code
Use G47.3 when the provider diagnoses sleep apnea and does not specify obstructive, central, or another subtype. It also fits follow-up visits when the condition remains the active documented diagnosis. Check documentation if the type is unclear.
Do not use for
Do not use this code when the record specifies a different sleep apnea type that has its own code. Avoid using it for simple snoring or insomnia without documented sleep apnea.
Coding tip
Confirm the exact sleep apnea type in the note before coding, because specificity may change the ICD-10 code selection.
