About coding neonatorum erythema
The ICD-10-CM code for neonatorum erythema is P83.88 (Other specified conditions of integument specific to newborn). The official index lists 1 more specific code, so check the documentation for details such as type, cause, site or severity before settling on P83.88.
Within P83.8, choose P83.88 (Other specified conditions of integument specific to newborn) only when documentation doesn't support a more specific option: umbilical granuloma (P83.81).
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.
