Private health insurance premium increases—an overview
Introduction
Annually the Health Minister announces the average increase for health insurance premiums
following the Government’s assessment of applications from health insurers. This attracts
considerable media attention. Insurers that then announce premium rises larger than the
figure announced by the Minister, may attract consumer complaints to the Private Health
Insurance Ombudsman.1
On 2 March 2009, the Health Minster announced that premiums for health insurance products
would increase by an industry average of 6.02 per cent from 1 April 2009.2 This average
increase is in line with a five year average annual increase of 6.1 per cent.3
This background note provides an overview of rises in private health insurance premiums in
recent years, outlines possible reasons for these increases and for variations in the increases
experienced by individual funds, and outlines recent changes to the regulation of private
health insurance that may affect how premium rises are assessed and how they are reported.
Approval process for premium increases
Health insurers wanting to increase their premiums are required under legislation to seek
regulatory approval. Applications for premium increases can be made by a health insurer at
any time; however, the practice of applying for an annual increase early in the year remains
the norm.
Over time there have been changes to the procedures governing the approval of premium
rises. In 1996, the Howard Government introduced the practice whereby premium increases
required approval by the Health Minister, in consultation with the Prime Minister and the
Treasurer.4 Following an interdepartmental review of health insurance arrangements in 2003,
the process for seeking premium rises at or below the consumer price index (CPI) was
‘streamlined’. Those health insurers applying for lower-than-CPI increases were not required
to provide as much information to support their claim, nor undergo the same level of scrutiny,

For example, following premium rises in 2003, the Private Health Insurance Ombudsman
received a record number of complaints relating to premium increases. Private Health Insurance
Ombudsman, Annual Report 2003, PHIO, Canberra, 2003, p. 22. In recent years, the number of
complaints relating to premium increases has declined.

as those applying for higher-than-CPI increases.5 The Health Minister was empowered to
disallow any premium increase if it:
•
could breach a condition of registration or other section of the National Health Act 1953
•
imposes an unreasonable or inequitable condition affecting the rights of any contributor
•
adversely affects a fund's stability
•
would be contrary to the public interest.6
Any changes to premiums were required to be tabled in Parliament.
In 2007, legislative changes affecting the process for seeking premium increases were made
with the passage of the Private Health Insurance Act 2007. The notification period whereby a
health insurer can seek approval from the Minister to increase its premiums has been
lengthened from 14 days to 60 days—allowing health insurers a longer time to make
applications. The Minister is now required to approve all premium increases, unless this
‘would be contrary to the public interest’. Except in the case of public interest, the other
former criteria for disallowing increases are no longer specified in the Act. If the Minister
does not allow an increase the reasons for this have to be publicly disclosed.7 Effectively, this
represents a significant shift away from the onus being on insurers to ensure that their
proposed increases are compatible with specified criteria, to the onus being on the Minister to
show cause for not approving an increase. Furthermore, the only remaining specified reason
to disallow an increase—the public interest test—remains undefined.
In addition, the new Act altered the way premium increases are notified; it is no longer a
requirement that information on premium rises granted to individual insurers be tabled in
Parliament. However, the Minister is required to table reasons for not approving an increase.8
The new Act also included changes to the articulation of the objectives of the industry
regulator, the Private Health Insurance Administration Council (PHIAC). PHIAC provides
advice to the Minister (and the public) about the health insurance sector. This includes
advising the Minister on premium rises.

Private health insurance premium increases—an overview
PHIAC’s new role is broadly defined as attempting to ‘achieve a balance between its various
objectives’, which as stated in the Act includes:
•
fostering an efficient and competitive health insurance industry, and
•
protecting the interests of consumers, and ensuring the prudential safety of individual
private health insurers.9
While PHIAC continues to provide advice on premium rises, its former objective of
‘minimising the level of health insurance premiums’ has however been removed from the
Act. This has met with some criticism with some arguing this objective was ‘vitally
important’.10
Trends in recent premium increases
Generally, average premium rises in recent years have been well above the CPI, as shown in
Table 1. Premium rises are driven by a combination of factors, the major ones being:
•
an ageing population that increases utilisation and benefit outlays
•
adverse selection, which sees younger, healthier people foregoing health insurance, but not
those most likely to need treatment
•
rising costs associated with advances in medical technology and new treatments, and
•
unavoidable cost pressures, such as provider costs rising faster than the CPI, prostheses
costs and Medicare Benefit Schedule increases not in line with other cost increases.11

Section 82BA(2)(c) of the National Health Act 1953, containing this objective was repealed.

important’ and should be retained. See A Biggs, L Buckmaster, Private Health Insurance Bill

Premium increases can vary across the sector with some insurers applying for and being
granted higher premium increases than others. This can be due to a range of factors: in
addition to variations in annual costs due to changed claiming patterns, there can also be
changes in reserve levels, and in the investment income of individual funds from year to
year.13 Fluctuations in annual premium increases for individual health insurance products
offered by health insurers can also occur.

Private health insurance premium increases—an overview
The table below shows that in recent years the annual premium increases of Medibank
Private—the largest health insurer by market share—have hovered around the industry
average.14 However, the range of premium increases experienced by individual insurers over
the same period has at times, been quite large. In 2002 one fund reported a premium increase
of 40.5 per cent compared to the industry average increase of 6.9 per cent for that year.15

Private health insurance premium increases—an overview
Consumer information
In the past, details of the approved average premium increase to be applied to the range of
insurance products offered by individual funds had been publicly released. While a number of
health insurers do continue to provide such information on their websites, as noted above, the
requirement to table this information in Parliament has not applied since the introduction of
the new Act.20 Although health insurers are required to provide information to the public on
the price of their individual health insurance products, they are not required to provide details
of the average premium rise that will apply to their products.21
In the lead up to the 2009 announcement of premium increases, the Minister warned health
insurers not to propose large increases to premiums as a result of legislative changes that saw
increases to the Medicare Levy Surcharge (MLS) income thresholds.22 Significantly, the
Minister also indicated she was considering making changes to the level of consumer
information about premium increases by publishing the details of the average premium rise
for each individual fund, rather than the usual practice of only publishing the industry-wide
average. The intention, she stated, was ‘to enable consumers to assess their own fund’s
performance against alternatives’ and ‘drive more competition’.23 However, when the annual
premium increases were announced by the Minister in March 2009, only the average
premium increase across the sector was provided. There was however a subsequent
announcement in the 2009–10 Budget context that from 2010 the Government intends to

20. Under the now repealed Section 78 (8) of the National Health Act 1953 information on
premium increases was tabled in Parliament (generally under the title ‘Report on private health
insurance premium increases’) and was also made available by the Private Health Insurance
Administration Council on its website, but this information is no longer available. Some reports
on premium increases are retrievable through the Internet Archive. See Report on premium
increases with date of effect in the quarter ending June 2007, viewed 6 April 2009.

Nor are they required to advise the public about the premium rises they seek approval for each
year, as these are regarded as commercial in confidence.
22.
The income thresholds for the MLS—a surcharge which applies to high income earners who
opt out of private health insurance—were increased in late 2008. This led to claims that as a
result, many would drop their private health insurance having a consequent impact on health
insurance premium costs. M Davis, ‘Health funds warned over premium rises’, Sydney

Private health insurance premium increases—an overview
publish individual insurers’ average premium increases, in order to ‘enhance the transparency
of the premium-setting process’.24
Concluding comments
Over the last five years, increases to private health insurance premiums have averaged around
6 per cent—that these have been well above CPI increases has attracted some public concern.
However, premium increases higher than CPI can be expected into the future as there remain
a range of cost drivers pushing up the costs of health services; such as an ageing population,
advances in expensive medical technologies and treatments, and the impact of the economic
downturn, to name a few. Other recent regulatory changes affecting the MLS and the private
health insurance rebate may also influence insurers’ decisions to seek increases to the level of
their premiums.
Nevertheless there has been considerable variation in the increases of individual funds, some
being substantially higher than the average. Competition and consumer choice between these
funds have not been assisted by recent legislative changes to the reporting requirements of
premium increases that have meant that that there is now less information publicly available
on the premium increases of individual funds. The Government’s recent announcement that
from 2010 it will make available consumer information on individual private health insurance
premium increases should alleviate this situation.
Other legislative changes introduced in 2007 may however continue to affect the
Government’s process for considering premium increases. There is now only one specified
reason in the legislation for disallowing an increase—the public interest test—but precisely
what is meant by ‘public interest’ remains unclear and so far, untested. At the same time the
industry regulator’s role has been recast. PHIAC’s formerly explicit objective of ‘minimising
the level of health insurance premiums’ is no longer one of its specified legislative objectives.
Any impact of this is yet to emerge.
In such an environment, transparency about the premium-setting process and the availability
of consumer information about premium rises and the drivers of those rises are likely to
become of greater import.
