About coding born in hospital newborn
The ICD-10-CM code for born in hospital newborn is Z38.00 (Single liveborn infant, delivered vaginally). The official index lists 1 more specific code, so check the documentation for details such as type, cause, site or severity before settling on Z38.00.
Within Z38.0 (single liveborn infant, born in hospital), Z38.00 is specifically for single liveborn infant, delivered vaginally. Related codes cover by cesarean (Z38.01).
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.
