Waiting times are calculated for patients whose reason for removal was:

1. admitted as an elective patient for awaited procedure by or on behalf of this hospital or the state/territory.

Waiting time is calculated by states and territories by subtracting the listing date for care from the removal date, minus any days the patient was not ready for care and/or waiting with a less urgent clinical urgency category than their clinical urgency category at removal.

The calculation of waiting time excludes:

• any days the patient was waiting with a less urgent elective surgery urgency category than their urgency category at removal. When a patient's urgency category changes, existing NMDS business rules will apply.
• people who were transferred to another hospital’s elective surgery waiting list, were treated elsewhere but not on behalf of the hospital, were not contactable, died prior to receiving their surgery or declined surgery.
