Appendix removal
Without complications or comorbidities

Appendix removal (also called appendectomy) is a surgical procedure which is performed either through keyhole surgery or open surgery. The data presented here relate to costs incurred by a hospital for patients who were admitted for the removal of the appendix without complications or comorbidities, malignant cancer or peritonitis.

In 2011–12, there were 13,099 admissions for appendix removal without complications or comorbidities, malignant cancer or peritonitis in major metropolitan and major regional public hospitals.

CACost per Admission

Across all major metropolitan hospitals, the average cost per admission for appendix removal was $6,300. The average cost per admission ranged from $4,600 at one hospital to $10,100 at another hospital.

Across all major regional hospitals, the average cost per admission for appendix removal was $6,300. The average cost per admission ranged from $4,300 at one hospital to $9,300 at another hospital.

LOSLength of Stay

A previous Authority report showed the average length of stay for appendix removal in 2011–12 was 2.2 days.7 At major metropolitan hospitals, the average length of stay ranged from 1.6 to 3.0 days, and at major regional hospitals the average length of stay ranged from 1.6 to 2.8 days.7

By comparing the cost of a patient’s appendix removal to their length of stay it is possible to assess the incremental cost that each additional day(s) spent in hospital contributes to the patient’s costs of care (see Figure 4).

It is important to note that these costs do not reflect the total costs of this procedure. The report considers only the subset of total costs that are fully comparable between hospitals. For example, it excludes property, plant and equipment costs.
