P27Chronic respiratory disease originating in the perinatal period

P27 is the ICD-10-CM diagnosis code for chronic respiratory disease 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 4 subcodes must be used instead.

To report this condition, pick the subcode that matches the documentation: P27.0 (syndrome), P27.1 (period), P27.8 (period) and P27.9 (period).

The conditions in its Excludes2 note aren't part of P27, but may be coded alongside it if the patient has both: respiratory distress of newborn (P22.0-P22.9).

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