ICD-10 code for fetalis hydrops

The ICD-10-CM code for fetalis hydrops is P83.2 (Hydrops fetalis not due to hemolytic disease). The official index lists 7 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on P83.2.

Within P83 (other conditions of integument specific to newborn), P83.2 is specifically for hydrops fetalis not due to hemolytic disease. Related codes cover Sclerema neonatorum (P83.0), neonatal erythema toxicum (P83.1), other and unspecified edema specific to newborn (P83.3), breast engorgement of newborn (P83.4), congenital hydrocele (P83.5), umbilical polyp of newborn (P83.6), other specified conditions of integument specific to newborn (P83.8) and condition of the integument specific to newborn, unspecified (P83.9).

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.
