ICD-10 code for neonatal transient diabetes

The ICD-10-CM code for neonatal transient diabetes is P70.2 (Neonatal diabetes mellitus).

Within P70 (transitory disorders of carbohydrate metabolism specific to newborn), P70.2 is specifically for neonatal diabetes mellitus. Related codes cover syndrome of infant of mother with gestational diabetes (P70.0), syndrome of infant of a diabetic mother (P70.1), iatrogenic neonatal hypoglycemia (P70.3), other neonatal hypoglycemia (P70.4), other transitory disorders of carbohydrate metabolism of newborn (P70.8) and transitory disorder of carbohydrate metabolism of newborn, unspecified (P70.9).

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.
