About coding breast engorgement newborn
The ICD-10-CM code for breast engorgement newborn is P83.4 (Breast engorgement of newborn).
Within P83 (other conditions of integument specific to newborn), P83.4 is specifically for breast engorgement of newborn. Related codes cover Sclerema neonatorum (P83.0), neonatal erythema toxicum (P83.1), hydrops fetalis not due to hemolytic disease (P83.2), other and unspecified edema specific to newborn (P83.3), congenital hydrocele (P83.5), umbilical polyp of newborn (P83.6), other specified conditions of integument specific to newborn (P83.8) and condition of the integument specific to newborn, unspecified (P83.9).
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.
