Cold injury syndrome

This code represents a systemic response in a newborn to prolonged or severe cold exposure, leading to a constellation of symptoms beyond simple hypothermia. It encompasses a range of physiological dysfunctions, including metabolic acidosis, hypoglycemia, and respiratory distress, specifically due to cold stress in the neonatal period.

Use this code when documentation clearly indicates a newborn suffering from a systemic syndrome directly attributable to cold exposure, characterized by symptoms such as lethargy, poor feeding, respiratory difficulties, and metabolic derangements. This diagnosis requires more than just a low body temperature; it implies a broader impact on the infant's physiological systems.

• Differentiate from mild hypothermia of newborn (P80.8) which is explicitly excluded; this code signifies a more severe, syndromic presentation.
• Ensure documentation supports systemic involvement and not just isolated low body temperature.
• Consider sequencing with codes for specific manifestations of the syndrome, such as hypoglycemia or metabolic acidosis, if documented.
