About P28.4

P28.4 is the ICD-10-CM diagnosis code for other apnea of newborn. It belongs to category P28 (other respiratory conditions originating in the perinatal period), block P19-P29 (respiratory and cardiovascular disorders specific to the perinatal period) and chapter 16 (certain conditions originating in the perinatal period). It is a header code, so it can't be reported by itself; one of its 5 subcodes must be used instead.

Within P28, choose P28.4 (Other apnea of newborn) only when documentation doesn't support a more specific option: primary atelectasis of newborn (P28.0), other and unspecified atelectasis of newborn (P28.1), Cyanotic attacks of newborn (P28.2), primary sleep apnea of newborn (P28.3), respiratory failure of newborn (P28.5), other specified respiratory conditions of newborn (P28.8) and respiratory condition of newborn, unspecified (P28.9).

To report this condition, pick the subcode that matches the documentation: P28.40 (newborn), P28.41 (newborn), P28.42 (newborn), P28.43 (newborn) and P28.49 (newborn).

The conditions in its Excludes2 note aren't part of P28.4, but may be coded alongside it if the patient has both: primary 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 changed in FY2023 (expanded into subcodes).

Before ICD-10, this condition was coded in ICD-9-CM as 770.82 (other apnea of newborn).
