About coding neonatal hepatitis
The ICD-10-CM code for neonatal hepatitis is P59.29 (Neonatal jaundice from other hepatocellular damage).
Within P59.2, choose P59.29 (other hepatocellular damage) only when documentation doesn't support a more specific option: unspecified hepatocellular damage (P59.20).
As a secondary diagnosis it is an MCC (major complication or comorbidity), which can move an inpatient stay into the highest-paying "with MCC" MS-DRG of its family, unless the principal diagnosis excludes it.
In MS-DRG v44.0, it is part of the grouping logic for DRG 791 (Prematurity with Major Problems, relative weight 4.1075) and DRG 793 (Full Term Neonate with Major Problems, relative weight 4.2195), 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.
