P70.1Syndrome of infant of a diabetic mother

P70.1 is the ICD-10-CM diagnosis code for syndrome of infant of a diabetic mother. It belongs to category P70 (transitory disorders of carbohydrate metabolism specific to newborn), block P70-P74 (transitory endocrine and metabolic disorders specific to newborn) and chapter 16 (certain conditions originating in the perinatal period). It is billable, so it can be reported on its own for dates of service from October 1, 2026 through September 30, 2027.

Within P70 (transitory disorders of carbohydrate metabolism specific to newborn), P70.1 is specifically for syndrome of infant of a diabetic mother. Related codes cover syndrome of infant of mother with gestational diabetes (P70.0), neonatal diabetes mellitus (P70.2), 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).

Don't report P70.1 together with the conditions in its Excludes1 note: newborn (with hypoglycemia) affected by maternal gestational diabetes (P70.0) and syndrome of infant of mother with gestational diabetes (P70.0).

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.

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.

Before ICD-10, this condition was coded in ICD-9-CM as 775.0 (syndrome of "infant of a diabetic mother").
