The competition watchdog has lodged an appeal against the Federal Court's dismissal of its allegations that Medibank misled customers over changes to benefits.
The Australian Competition and Consumer Commission's allegation that Medibank deliberately failed to notify members of new limits on pathology and radiology benefits was dismissed in August by the Federal Court.
"It is important that the ACCC seeks clarity from the full Federal Court on ... the extent to which it was acceptable for Medibank not to fully inform vulnerable consumers about changes to their private health insurance," ACCC chairman Rod Sims said on Thursday.
