Other hypothermia of newborn

This code signifies a newborn's core body temperature falling below 36.5°C (97.7°F) due to causes other than those specifically classified as mild, moderate, or severe hypothermia, or cold stress. It indicates a generalized decrease in body temperature that is not severe enough to warrant a more specific hypothermia code but still requires clinical attention.

Use this code when documentation specifies hypothermia in a newborn without further detail regarding severity (e.g., "newborn hypothermia, unspecified severity" or "mild hypothermia not otherwise specified"). It is appropriate when the physician's notes indicate a low body temperature that doesn't fit the criteria for P80.0, P80.1, or P80.9.

• Ensure the documentation explicitly states "newborn" to differentiate from hypothermia in older infants or adults.
• Always review the medical record for more specific details on the severity of hypothermia (e.g., mild, moderate, severe) to determine if a more precise code (P80.0, P80.1) is applicable.
• This code should be sequenced as a primary diagnosis if it is the reason for admission or primary focus of care, or as a secondary diagnosis if it is a co-morbidity.
