About P59.0
P59.0 is the ICD-10-CM diagnosis code for neonatal jaundice associated with preterm delivery. It belongs to category P59 (neonatal jaundice from other and unspecified causes), block P50-P61 (hemorrhagic and hematological disorders of newborn) and chapter 16 (certain conditions originating in the perinatal period). It is billable, so it can be reported on its own for dates of service from October 1, 2026 through September 30, 2027.
Within P59 (neonatal jaundice from other and unspecified causes), P59.0 is specifically for neonatal jaundice associated with preterm delivery. Related codes cover inspissated bile syndrome (P59.1), neonatal jaundice from other and unspecified hepatocellular damage (P59.2), neonatal jaundice from breast milk inhibitor (P59.3), neonatal jaundice from other specified causes (P59.8) and neonatal jaundice, unspecified (P59.9).
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.
It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
Before ICD-10, this condition was coded in ICD-9-CM as 774.2 (neonatal jaundice associated with preterm delivery).
