P29.1Neonatal cardiac dysrhythmia

P29.1 is the ICD-10-CM diagnosis code for neonatal cardiac dysrhythmia. 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 (cardiovascular disorders originating in the perinatal period), P29.1 is specifically for neonatal cardiac dysrhythmia. Related codes cover neonatal cardiac failure (P29.0), neonatal hypertension (P29.2), persistent fetal circulation (P29.3), transient myocardial ischemia in newborn (P29.4), other cardiovascular disorders originating in the perinatal period (P29.8) and cardiovascular disorder originating in the perinatal period, unspecified (P29.9).

To report this condition, pick the subcode that matches the documentation: P29.11 (tachycardia) and P29.12 (bradycardia).

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