About coding primary respiration delay
The ICD-10-CM code for primary respiration delay is P28.9 (Respiratory condition of newborn, unspecified).
Within P28, choose P28.9 (Respiratory condition of newborn, unspecified) only when documentation doesn't support a more specific option: primary atelectasis of newborn (P28.0), other and unspecified atelectasis of newborn (P28.1), Cyanotic attacks of newborn (P28.2), primary sleep apnea of newborn (P28.3), other apnea of newborn (P28.4), respiratory failure of newborn (P28.5) and other specified respiratory conditions of newborn (P28.8).
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.
