P29Cardiovascular disorders originating in the perinatal period

P29 is the ICD-10-CM diagnosis code for cardiovascular disorders 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 7 subcodes must be used instead.

To report this condition, pick the subcode that matches the documentation: P29.0 (failure), P29.1 (dysrhythmia), P29.2 (hypertension), P29.3 (circulation), P29.4 (newborn), P29.8 (period) and P29.9 (unspecified).

The conditions in its Excludes2 note aren't part of P29, but may be coded alongside it if the patient has both: congenital malformations of the circulatory system (Q20-Q28).

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