About coding Omphalitis newborn
The ICD-10-CM code for Omphalitis newborn is P38.9 (Omphalitis without hemorrhage). The official index lists 2 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on P38.9.
Within P38, choose P38.9 (without hemorrhage) only when documentation doesn't support a more specific option: with mild hemorrhage (P38.1).
As a secondary diagnosis it is a CC (complication or comorbidity), which can move an inpatient stay into the "with CC" 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.
