About G47.3
G47.3 is the ICD-10-CM diagnosis code for sleep apnea. It belongs to category G47 (sleep disorders), block G40-G47 (episodic and paroxysmal disorders) and chapter 6 (diseases of the nervous system). It is a header code, so it can't be reported by itself; one of its 9 subcodes must be used instead.
Within G47 (sleep disorders), G47.3 is specifically for sleep apnea. Related codes cover insomnia (G47.0), hypersomnia (G47.1), circadian rhythm sleep disorders (G47.2), Narcolepsy and cataplexy (G47.4), parasomnia (G47.5), sleep related movement disorders (G47.6), other sleep disorders (G47.8) and sleep disorder, unspecified (G47.9).
To report this condition, pick the subcode that matches the documentation: G47.30 (unspecified), G47.31 (apnea), G47.32 (breathing), G47.33 ((pediatric)), G47.34 (hypoventilation), G47.35 (syndrome), G47.36 (elsewhere), G47.37 (elsewhere) and 1 more.
Don't report G47.3 together with the conditions in its Excludes1 note: apnea NOS (R06.81), Cheyne-Stokes breathing (R06.3), pickwickian syndrome (E66.2) and sleep apnea of newborn (P28.3-).
It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
