4.3.5 Interim to Final

Last amended 
12 April 2019

Once the injury for which interim compensation has been paid becomes both permanent and stable, a final payment of permanent impairment should be paid under section 24 of the DRCA for the injury.

This requires that the delegate reassess the injury to establish the updated rate at which permanent impairment should be paid under section 24. This amount must then be compared with the amount already paid as an interim permanent impairment amount under section 25.

The difference between these amounts is the amount payable to the client for the final permanent impairment determination. Further instructions on how to consider the full section 24 permanent impairment process can be found at Chapter 4.2 and Chapter 5 of this library.

Note that there is no 10% threshold increase required between the interim assessment and the final assessment for final permanent impairment compensation to be paid. For example, if a condition that is payable at 10% as an interim is then assessed under the permanent impairment guide 12 months later as now being permanent and stable at 15% for a final payment, the difference in rates is payable (ie including the annual indexation). 

At this point a non-economic loss payment under section 27 of the DRCA should also be calculated and paid.
