About coding neonatal bradycardia
The ICD-10-CM code for neonatal bradycardia is P29.12 (Neonatal bradycardia).
Within P29.1 (neonatal cardiac dysrhythmia), P29.12 is specifically for neonatal bradycardia. Related codes cover tachycardia (P29.11).
It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.
In MS-DRG v44.0, it is part of the grouping logic for DRG 794 (Neonate with Other Significant Problems, relative weight 1.4935), in MDC 15 (Newborns and Other Neonates with Conditions Originating in the Perinatal Period), as a principal or secondary diagnosis. The DRG a claim lands in depends on the principal diagnosis, procedures and any CC/MCC secondary diagnoses.
