Error 91 means that your health fund is currently experiencing issues, and is not available for Medipass to connect to, either to process a quote or a claim.
While health fund systems usually operate 24/7, they can be down for either scheduled maintenance, or due to an unforeseen issue. The hours that each health fund aim to always be available can be found here.
If you receive this error, you can still pay for your service or product fully out of pocket via Medipass, and then submit a claim to your health fund manually (such as via their website or their app).
Alternatively, if you're attempting to pay for an item or service outside of the operational hours of your health fund, you can always return to continue the payment during operational hours.
We apologise if this has caused you an issue, and if you have any questions, please contact us at firstname.lastname@example.org.
