About coding neonatal candidiasis
The ICD-10-CM code for neonatal candidiasis is P37.5 (Neonatal candidiasis).
Within P37 (other congenital infectious and parasitic diseases), P37.5 is specifically for neonatal candidiasis. Related codes cover congenital tuberculosis (P37.0), congenital toxoplasmosis (P37.1), neonatal (disseminated) listeriosis (P37.2), congenital falciparum malaria (P37.3), other congenital malaria (P37.4), other specified congenital infectious and parasitic diseases (P37.8) and congenital infectious or parasitic disease, unspecified (P37.9).
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.
