What G47.33 covers
G47.33 is for obstructive sleep apnea, where the airway repeatedly narrows or closes during sleep. It applies to adults and children, and includes obstructive sleep apnea hypopnea.
Sleep medicine, pulmonology, ENT and primary care use it. Central sleep apnea has separate codes such as G47.31 (primary) and G47.37 (in conditions classified elsewhere). G47.30 is sleep apnea with the type not documented.
Billing and coding notes
The G47.3 subcategory says to code also any associated underlying condition. It also has an excludes1 for apnea NOS (R06.81), Cheyne-Stokes breathing (R06.3), pickwickian syndrome (E66.2) and sleep apnea of newborn (P28.3-).
Obstructive sleep apnea of a newborn is an excludes1 at this code too, so a newborn gets a P28.3- code. If the note just says "sleep apnea" without a type, G47.30 is the accurate choice, not G47.33.

Questions about G47.33
Is G47.33 used for children?
Yes. The title covers adult and pediatric obstructive sleep apnea. Only newborns are excluded, and they are coded in P28.3-.
Can G47.33 be coded with E66.2?
No. Pickwickian syndrome (E66.2, obesity with alveolar hypoventilation) is an excludes1 at G47.3.
