Disturbance of temperature regulation of newborn, unsp

This code signifies a newborn experiencing an uncharacterized issue with maintaining a stable body temperature. It indicates that the infant's thermoregulation system is not functioning optimally, leading to either hypothermia or hyperthermia, but the specific cause or nature of the disturbance is not documented.

Apply this code when a newborn presents with an abnormal body temperature (e.g., fever, hypothermia) and the medical record lacks further specificity regarding the underlying cause or type of temperature dysregulation. Documentation should clearly state "disturbance of temperature regulation" or similar, without additional details that would allow for a more specific code.

• Avoid using this code if a more specific diagnosis for the temperature disturbance is available (e.g., neonatal hypothermia, neonatal hyperthermia).
• Always review the entire medical record for additional information that might clarify the etiology of the temperature dysregulation.
• This code is a diagnosis of exclusion; only use it when no other specific code can be assigned.
