About P25

P25 is the ICD-10-CM diagnosis code for interstitial emphysema and related 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 5 subcodes must be used instead.

To report this condition, pick the subcode that matches the documentation: P25.0 (period), P25.1 (period), P25.2 (period), P25.3 (period) and P25.8 (period).

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