About P28

P28 is the ICD-10-CM diagnosis code for other respiratory conditions originating in the perinatal period. It belongs to 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 8 subcodes must be used instead.

To report this condition, pick the subcode that matches the documentation: P28.0 (newborn), P28.1 (newborn), P28.2 (newborn), P28.3 (newborn), P28.4 (newborn), P28.5 (newborn), P28.8 (newborn) and P28.9 (unspecified).

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
