Your Official Information Act request, reference: GOV-022857
Thank you for your request of 30 December 2022 asking for the following information:
Again, I have not requested the number of claims accepted, but the number of claims submitted to
ACC which were either Medical Misadventure or Medical Treatment Injury Claims. Would it be more
clear if I were to ask for the total number of claims submitted, total number of claims accepted and
total number of claims declined?
ACC does not capture cancer-related treatment injury data separately
ACC is unable to readily identify cancer-related treatment injury claims from its claims data. Extracting the
number of submitted or declined cancer claims would require us to manually review all treatment injury
claims submitted or declined to identify if they were cancer related. Therefore, we are refusing to provide
this data as it would require substantial collation and research to extract. This decision has been made
under section 18(f) of the Act.
As noted in our previous responses, cancer-related treatment injury data is limited to a group of claims
manually extracted and reviewed by the clinical services team in July 2021. Given the above, the cancer-
related claims counted in the table provided have been extracted from that group of accepted cancer-
related claims that were reviewed in July 2021. Consistent with our response of 10 November 2022, the
data provided covers claims accepted between 1 July 2016 and 30 June 2021.
