According to the Huffington Post, “full code” is a hospital term that implies to intervene if a patient’s heart or breathing stops. It is the reverse code of “Do Not Resuscitate/Do Not Intubate,” or DNR/DNI.
The Huffington Post reports that when a patient enters a hospital, she is automatically assigned a complete code unless she or her family requests otherwise. Being designated as full code authorises the hospital to attempt to revive a patient in a near-death condition. Patients have the option to consent to only particular emergency treatments, such as intubation but not resuscitation.
