Syndrome of infant of a diabetic mother

This code identifies a newborn exhibiting a specific set of signs and symptoms (syndrome) due to the mother having pre-existing diabetes (Type 1 or Type 2) prior to pregnancy. These infants often present with macrosomia, hypoglycemia, polycythemia, hyperbilirubinemia, and/or respiratory distress. The maternal diabetes directly impacts fetal development and postnatal adaptation.

Apply this code when documentation clearly indicates the infant's condition is a direct result of the mother having pre-existing diabetes. This diagnosis is supported by findings such as large for gestational age (LGA), neonatal hypoglycemia requiring intervention, or other metabolic disturbances in the newborn, coupled with a maternal history of pre-gestational diabetes.

• Differentiate carefully between maternal pre-existing diabetes and gestational diabetes; this code is specifically for pre-existing.
• Do not code this with P70.0, which is for infants affected by maternal gestational diabetes.
• Ensure the medical record explicitly links the infant's syndrome to the mother's pre-existing diabetic status.
