Other hypothermia of newborn

This code signifies a newborn experiencing abnormally low body temperature (hypothermia) that is not specifically classified as mild, moderate, or severe, or due to a specific underlying cause. It indicates a general diagnosis of hypothermia in a neonate, often observed shortly after birth.

Use this code when documentation indicates a newborn with a core body temperature below 36.5°C (97.7°F) that is not further specified. This applies to cases where the hypothermia is not due to a specific congenital anomaly, infection, or other clearly defined etiology. Documentation should confirm the newborn status and the presence of hypothermia.

• Differentiate from hypothermia in older infants or adults, which would use codes from the 991 series.
• Ensure the documentation clearly states "newborn" or "neonate" to support this code.
• If a specific cause of hypothermia is identified (e.g., sepsis, metabolic disorder), code the underlying condition first, and consider if an additional code for the hypothermia is still appropriate based on coding guidelines.
