P29.8Other cardiovascular disorders originating in the perinatal period

P29.8 is the ICD-10-CM diagnosis code for other cardiovascular disorders originating in the perinatal period. It belongs to category P29 (cardiovascular disorders 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 2 subcodes must be used instead.

Within P29, choose P29.8 (Other cardiovascular disorders originating in the perinatal period) only when documentation doesn't support a more specific option: neonatal cardiac failure (P29.0), neonatal cardiac dysrhythmia (P29.1), neonatal hypertension (P29.2), persistent fetal circulation (P29.3), transient myocardial ischemia in newborn (P29.4) and cardiovascular disorder originating in the perinatal period, unspecified (P29.9).

To report this condition, pick the subcode that matches the documentation: P29.81 (newborn) and P29.89 (period).

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