ICD-10 Code G47.30 – Sleep apnea, unspecified (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code G47.30 – Sleep apnea, unspecified
What it is
G47.30 identifies sleep apnea when the type is not specified in the record. Use it for documented sleep-disordered breathing with repeated pauses in breathing during sleep, but without a stated obstructive, central, or mixed subtype.
Clinical signs
Common findings include loud snoring, witnessed breathing pauses, gasping, and nonrestorative sleep. Daytime sleepiness, morning headaches, or poor concentration may be noted; clinical features vary, so refer to documentation.
When to use this code
Use this code when the clinician documents sleep apnea but does not specify the subtype, or the available report only says “sleep apnea.” It is also appropriate when the chart confirms apnea during sleep, yet the record lacks enough detail to assign a more specific code.
Do not use for
Do not use G47.30 if the documentation clearly identifies obstructive, central, or mixed sleep apnea. Also avoid it when the note only mentions snoring or suspected apnea without confirmation; check documentation.
Coding tip
Query for the apnea type when the diagnosis is incomplete, because a more specific code is preferred.
