You do not need to download a mobile app before you can use Medipass.
To use Medipass as a patient, you just need to set up an online account at my.medipass.io. When you pay for a service, or approve a claim from your private health insurer or Medicare, your healthcare provider will send you an SMS prompting you to open up that account on your mobile phone. If you haven't yet set up your account yet, that SMS will prompt you to create one and you can then approve the transaction from there.
If you would like, there is a mobile app you can use approve payments to providers and corresponding private health insurance claims. This app is called "HICAPS Go" and also includes a directory where you can find a healthcare provider and get quotes for their services. For more information about the HICAPS Go app, click here.
