Top health insurance complaints

Health insurance complaints have gone down three years in a row. But gripes remain around waiting periods, benefit payments and membership cancellation.

Each year, the Commonwealth Ombudsman issues a report detailing trends and issues in the Australian private health insurance market. It includes figures of the complaints the independent body receives regarding health insurance and private health funds.

Here are the key stats and what makes up the health industry's most complained about problems.

What’s in a complaint?

The Commonwealth Ombudsman role is to protect the interests of health insurance consumers. To this end, one of its key roles is dealing with complaints not only from health fund members but also from health funds, private hospitals, health insurance brokers and medical practitioners.

According to the Ombudsman, a complaint “must be an expression of dissatisfaction with a matter arising out of or connected with a private health insurance arrangement”.

Number of complaints each year since 2009-2020

Complaint numbers have been relatively steady over the last decade. That said, in the period covering 2013-14, a total of 4,265 complaints were received - a jump of 24% on the previous year.

Interestingly, the overall number of complaints has decreased by a significant amount in the past 5 years.

What’s behind most health insurance complaints?

There's no single issue that has prompts complaints to the Ombudsman. Instead, there are multiple issues and developments at play.

One of the key concerns among health fund members is the annual premium increase on 1 April each year. The cost of private health insurance is a constant topic of complaints received.

Another reason for this spike is a rise in what are sometimes referred to as “junk” policies. Most health funds offer entry-level hospital cover policies that only provide a basic level of cover. However, some consumers are unaware of the restrictions and exclusions that apply to their policy and often get a nasty surprise when they are hospitalised and find out that their health fund won’t offer any cover.

For a better understanding of the driving forces behind increased complaint numbers, let’s take a look at the most commonly complained about issues across the health insurance industry.

5 most common health insurance complaints

Number 1 icon

Membership cancellation: 71 complaints

Complaints about health fund membership are generally due to delays in funds processing policy cancellations, as well as funds cancelling memberships when premium payments are in arrears. Another significant cause for complaint was delays in issuing clearance certificates required by consumers to switch from one health fund to another.

Number 2 icon

General service issues: 65 complaints

Complaints about service issues tend to arise as a result of other complaints. These include issues such as poor customer service, funds being too slow to rectify simple issues, problems paying premiums and unsatisfactory internal processes for dealing with complaints.

Number 3 icon

Waiting periods: 62 complaints

Health funds generally impose a 12-month waiting period on treatments for pre-existing conditions, and disputes around what constitutes a pre-existing condition and how this waiting period is applied were a common cause for complaints.

Number 4 icon

Delay in benefit payment: 60 complaints

These complaints tend to come about in two ways. Either there's confusion about which symptoms are relied on for claims assessments, or a consumer misunderstands exactly how a pre-existing condition is defined. An example could be hospital and extras policies with unexpected exclusions and restrictions, which can often be misunderstood.

Number 5 icon

Service delays: 57 complaints

These complaints are usually from consumers struggling to contact their fund, or concerned about delays from a provider's customer service. Meanwhile, 45 complaints were made around incentives, with the majority (40) about the Lifetime Health Cover (LHC) loading. Other complaints included the Medicare Levy Surcharge (MLS) and the Private Health Insurance Rebate.

Health insurance complaints by fund

In the period from 1 January to 31 March 2021, complaints about health funds dominated the statistics, making up a whopping 772 (or 85%) out of 910 complaints received. Complaints about overseas visitors funds came next with 105, followed by Other (e.g. legislation, ambulance services, industry peak bodies) with 23, then health insurance brokers with 8 and hospitals with 2. Doctors, dentists and other medical providers scored a perfect zero.

This chart shows the weighted volume of complaints received by each health fund, according to the Commonwealth Ombudsman. The lower the number, the better. Only non-restricted funds with a national market share of at least 0.1% are included here. Medibank is seventh overall in this ranking. The weighting ensures that funds are compared fairly; larger funds serve more customers so can potentially get more complaints.

How do I make a health insurance complaint?
