About coding Hypopnea
The ICD-10-CM code for Hypopnea is G47.33 (Obstructive sleep apnea (adult) (pediatric)).
Within G47.3 (sleep apnea), G47.33 is specifically for obstructive sleep apnea (adult) (pediatric). Related codes cover unspecified (G47.30), primary central sleep apnea (G47.31), high altitude periodic breathing (G47.32), idiopathic sleep related nonobstructive alveolar hypoventilation (G47.34), congenital central alveolar hypoventilation syndrome (G47.35), sleep related hypoventilation in conditions classified elsewhere (G47.36), central sleep apnea in conditions classified elsewhere (G47.37) and other sleep apnea (G47.39).
Don't report G47.33 together with the conditions in its Excludes1 note: obstructive sleep apnea of newborn (P28.3-).
It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.
Don't confuse with (Excludes1 for G47.33)
- obstructive sleep apnea of newborn (P28.3-)
