Is Medibank legit?

Legit

Medibank is a genuine Australian health fund that began life as a government insurer, yet a claim can still leave you paying part of the bill. What it pays depends on your level of cover, yearly limits and any waiting period still running, and the gap between your provider's fee and that benefit is yours.

What we checked

  • Listed on the ASX since 2014
  • Head office in Melbourne
  • Ratings on other review websites: 4.5/5

Watch out for

  • A text claiming a missed payment on your cover, with a link that asks for your details.
  • Joining from another fund more than two months after leaving it, which brings extra waiting periods.
  • An extras claim late in the year, after your cover's annual limit for that service is used up.

Claim paid at less than you expected?

We help you write it, it gets its own public page, and you can have it sent to Medibank as a formal letter.

How do I contact Medibank customer service?

The feedback and complaints page on the Medibank website, linked in the contact details at the top of this page, sets out the other routes for a complaint, and you can also raise it in a Medibank store.

How do I escalate a complaint with Medibank?

Give your membership number, the claim or policy involved, what went wrong and when, every earlier reference number, and the exact outcome you want, such as a claim reassessed or a premium refunded.

Claim decision you want reviewed? We help you write the escalation in minutes, with the policy wording and the benefit statement side by side.

How do I cancel my Medibank health insurance?

To cancel Medibank health insurance, call 13 23 31 or use the routes on the Medibank website, and ask for written confirmation of the date your cover ends and of any premiums refunded or still owed. Before you cancel, check whether any claims are still being processed and when the next direct debit is due, and if you are switching to another fund, ask both funds to confirm in writing which waiting periods you have already served.

Check your bank statement after the end date. A premium taken for a period after the confirmed end date is a clear billing complaint, so note the date and amount and ask Medibank in writing to refund it.

Can I complain to the Commonwealth Ombudsman (Private Health Insurance Ombudsman) about Medibank?

Yes: the Commonwealth Ombudsman, through its Private Health Insurance Ombudsman role, deals with complaints in Australia about private health insurers such as Medibank, including benefits, incorrect information or advice, gap fees and overseas visitor or student health cover. The Ombudsman generally expects Medibank to have had the chance to put things right first, so keep a record of every call, letter and reference number.

Benefit refused or cover wrongly explained? Bring it through our complaint process: our trained AI opens a case for you and keeps coaching you on what to reply and when to push again.

Is that Medibank text about a missed payment real?

Be careful. Medibank warns that scammers pose as health funds with texts about a problem on your account, such as a missed payment, and with calls selling fake policies. Do not tap the link: log in to your Medibank account yourself to see whether anything is really owed.

What do people complain about most at Medibank?

Nothing has been reported about Medibank here yet. Our research shows what typically goes wrong at Australian private health insurers: claims refused because of waiting periods or exclusions, benefits paid at less than the member expected, gap payments larger than quoted, premiums or direct debits taken after a policy was cancelled, and confusion over what a level of hospital or extras cover includes.

Hit by a waiting period you did not know about, or a gap bigger than quoted? Be the first to report it: your case opens the record for the next Medibank member facing the same claim.

What happens after I submit my complaint?

Your complaint gets its own public page on Complain.biz and we get to work: we bring it to the attention of Medibank through emails, social media, paper complaint letters and other tools at our disposal.

And we stay with it after you file. Our trained AI opens a case file for you and keeps coaching: what to reply, when to push again, and how to escalate if nothing happens.

Can other consumers help me with my Medibank complaint?

Yes. We have an active community of consumers, and complaints here are public: people who ran into the same problem with Medibank can give you advice or back you up with their own story. A complaint with a community behind it is much harder to overlook.
