About the P70–P74 Code Range
The ICD-10 codes P70-P74 cover temporary endocrine and metabolic disorders unique to newborns, focusing on conditions related to carbohydrate metabolism, calcium and magnesium balance, thyroid function, and electrolyte disturbances in the perinatal period.
This range includes disorders like P70.0, the syndrome of an infant born to a mother with gestational diabetes, also referred to as "Infant of diabetic mother." It spans neonatal diabetes mellitus (P70.2) and various forms of neonatal hypoglycemia, both iatrogenic and spontaneous. Transitory disturbances of calcium and magnesium metabolism are coded from P71.0 to P71.9, including neonatal hypocalcemia linked to cow’s milk and other causes. The codes P72.0 to P72.9 address transient neonatal endocrine disorders, such as neonatal goiter and hyperthyroidism, also known as neonatal thyrotoxicosis. The P74 series captures electrolyte imbalances like hypernatremia (P74.21) and hypokalemia (P74.32), alongside metabolic disturbances such as transient hyperammonemia and tyrosinemia. These codes help healthcare providers precisely identify and document newborn metabolic and endocrine issues that are temporary and specific to this early life stage.
