About coding jaundice newborn
The ICD-10-CM code for jaundice newborn is P59.9 (Neonatal jaundice, unspecified). The official index lists 6 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on P59.9.
Within P59, choose P59.9 (Neonatal jaundice, unspecified) only when documentation doesn't support a more specific option: neonatal jaundice associated with preterm delivery (P59.0), inspissated bile syndrome (P59.1), neonatal jaundice from other and unspecified hepatocellular damage (P59.2), neonatal jaundice from breast milk inhibitor (P59.3) and neonatal jaundice from other specified causes (P59.8).
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 795 (Normal Newborn, relative weight 0.2022), 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.
