Code 1 Emergency admission
The following guidelines may be used by health professionals, hospitals and health insurers in determining whether an emergency admission has occurred. These guidelines should not be considered definitive.

An emergency admission occurs if one or more of the following clinical conditions are applicable such that the patient required admission within 24 hours.

Such a patient would be: 
- at risk of serious morbidity or mortality and requiring urgent assessment and/or resuscitation; or 
- suffering from suspected acute organ or system failure; or 
- suffering from an illness or injury where the viability or function of a body part or organ is acutely threatened; or 
- suffering from a drug overdose, toxic substance or toxin effect; or 
- experiencing severe psychiatric disturbance whereby the health of the patient or other people is at immediate risk; or 
- suffering severe pain where the viability or function of a body part or organ is suspected to be acutely threatened; or 
- suffering acute significant haemorrhage and requiring urgent assessment and treatment; or 
- suffering gynaecological or obstetric complications; or 
- suffering an acute condition which represents a significant threat to the patient's physical or psychological wellbeing; or 
- suffering a condition which represents a significant threat to public health.

If an admission meets the definition of emergency above, it is categorised as emergency, regardless of whether the admission occurred within 24 hours of such a categorisation being made, or after 24 hours or more.

Code 2 Elective admission
If an admission meets the definition of elective care, it is categorised as elective, regardless of whether the admission occurred after 24 hours or more, or it occurred within 24 hours. The distinguishing characteristic is that the admission could be delayed by at least 24 hours.

Scheduled admissions: 
A patient who expects to have an elective admission will often have that admission scheduled in advance. Whether or not the admission has been scheduled does not affect the categorisation of the admission as emergency or elective, which depends only on whether it meets the definitions above. That is, patients both with and without a scheduled admission can be admitted on either an emergency or elective basis.

Code 3 Not assigned
Admissions for which an 'Elective patient status' is usually not assigned: 
- admissions for normal delivery (obstetric)
- admissions which begin with the birth of the patient, or when it was intended that the birth occur in the hospital, commence shortly after the birth of the patient
- statistical admissions
- planned readmissions for the patient to receive limited care or treatment for a current condition, for example dialysis or chemotherapy.
