The National Institute for Health and Clinical Excellence (NICE) has issued full guidance to the NHS in England, Wales, Scotland and Northern Ireland on Therapeutic hypothermia following cardiac arrest.


People who have a cardiac arrest can sometimes develop neurological problems because of the lack of oxygen to the brain.

In this procedure, after resuscitation a cooling device is used to reduce the person’s core temperature to 32–34°C to reduce the risk of developing neurological problems.

Coding recommendations

X51.2 Active cooling

In addition the ICD-10 code I46.0 Cardiac arrest with successful resuscitation is assigned.
