ICD-10 code for neonatal transitory hypoglycemia

The ICD-10-CM code for neonatal transitory hypoglycemia is P70.4 (Other neonatal hypoglycemia). The official index lists 1 more specific code, so check the documentation for details such as type, cause, site or severity before settling on P70.4.

Within P70, choose P70.4 (Other neonatal hypoglycemia) only when documentation doesn't support a more specific option: syndrome of infant of mother with gestational diabetes (P70.0), syndrome of infant of a diabetic mother (P70.1), neonatal diabetes mellitus (P70.2), iatrogenic neonatal hypoglycemia (P70.3), other transitory disorders of carbohydrate metabolism of newborn (P70.8) and transitory disorder of carbohydrate metabolism of newborn, unspecified (P70.9).

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 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.
