About coding Anaerosis of newborn
The ICD-10-CM code for Anaerosis of newborn is P28.89 (Other specified respiratory conditions of newborn).
Within P28.8, choose P28.89 (Other specified respiratory conditions of newborn) only when documentation doesn't support a more specific option: respiratory arrest of newborn (P28.81).
Don't report P28.89 together with the conditions in its Excludes1 note: early congenital syphilitic rhinitis (A50.05).
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 P28.89)
- early congenital syphilitic rhinitis (A50.05)
