When it comes to insurers’ freedom to set premium rates, Article 8(3) of the First Non-Life Insurance Directive7 and Articles 29 and 39(2) and (3) of the Third Non-Life Insurance Directive provide: ‘[. . .] Member States may not retain or introduce prior notification or approval of proposed increases in premium rates except as part of general price-control systems’.
Article 54 of the Third Non-Life Insurance Directive provides an exception to this rule. A Member State’s supervisory authority may impose specific measures in the form of restrictions on insurance contracts in the interest of the ‘general good’, where contracts covering health risks ‘may serve as a partial or complete alternative to health cover provided by the statutory social security system’. Where this is the case, a Member State can require private insurers to ‘comply with the specific legal provisions adopted by that Member State to protect the general good in that class of insurance’.8 A number of legal provisions may be introduced if private cover provides a partial or complete alternative to statutory cover: open enrolment, community rating, lifetime cover, policies standardised in line with the cover provided by the statutory health insurance scheme at a premium rate at or below a prescribed maximum, participation in risk equalisation schemes (referred to as ‘loss compensation schemes’) and the operation of private health insurance on a technical basis similar to life insurance.9 Measures taken to protect the general good must be shown to be necessary and proportional to this aim; not unduly restrict the right of establishment or the freedom to provide services; and apply in an identical manner to all insurers operating within a member state.
In his letter of 25 November 2008, European Commissioner Bolkestein, responding to a question from the Dutch government on the application of
Under certain conditions, national governments can restrict the application of free market principles to private health insurance. A restriction on free competition may be justified where it serves overriding requirements relating to the public interest, is suitable for securing the attainment of the objective which it pursues and does not go beyond what is necessary in order to attain it.12
3 eu Case Law on Price Regulation of Additional Health Insurance
In recent years, the
These two cases, which each concern price regulation, illustrate the need for discussion on the appropriate balance between regulation and the operation of the free market in the additional health insurance sector more broadly. This important issue of health policy will be discussed in more depth in section 5. Before that, in section 4, we will bring into the discussion two legal elements that are relevant to consideration of the appropriate balance to be drawn, the concept of services of general economic interest and the proportionality of national regulation aiming at restricting free market.

3.2.1 Health Insurance System
Belgium has a system of compulsory health insurance with a very broad benefits package. Health insurance is part of a Bismarckian social security system. Compulsory health insurance is administered by seven sickness funds. Every citizen is obliged to be a member of a sickness fund.
In 2015, Belgium had the 8th highest healthcare expenditure per capita measured in purchasing power parity among the
Additional health insurance covers less than 5 per cent of total expenditure on health.29 Half of this 5 per cent consists of services and benefits provided by the sickness funds to their members and for which the sickness funds request a membership fee. These services and benefits are very diverse, e.g., reimbursement of travel vaccines or reimbursement of the membership fees of sport clubs. In addition to these services and benefits, which are accessible for the entire population, about three-quarters of the population has taken out voluntary additional health insurance, known as ‘hospitalisation insurance’ (‘hospitalisatieverzekering’ (Dutch) / ‘assurance hospitalisation’ (French)).30 This hospitalisation insurance covers supplements and co-payments.31 There are three types of supplements, which are not covered by compulsory health insurance: fee supplements, room supplements and material supplements.
A fee supplement is an extra fee charged by healthcare providers on top of the official tariff set by the social security regime (‘ereloonsupplement’ (Dutch) / ‘supplément d’honoraires’ (French)).32 In a hospital setting, fee supplements may only be charged to patients staying in a private, one-bed room. In 2015, one out of every four patients stayed in a private room.33 In hospitals, fee supplements range between one and three times the official tariff, with significant variations between the supplements in different regions.34 In a similar way to a fee supplement, a room supplement is charged by the hospital for the use of a private, one-bed room. When a stay in a private room is necessary because of medical reasons, room supplements may not be charged. A ‘material’ supplement is requested for medical material which is not (yet) reimbursed by social security, e.g., non-reimbursable pharmaceuticals or a new hip implant.35 The costs linked to the use of a private hospital room — i.e., fee and room supplements — account for about half of total reimbursements made by hospitalisation insurance programmes.36 Whereas the total patient bill has been decreasing over the past ten years, this is not the case for fee supplements which have been steadily increasing.37
In order to curb the — often high — premium rate increases under hospitalisation insurance contracts, a ‘medical index’ has been created by law. Premium rates can only be increased in line with the consumer prices index or the medical index.38 Only when an additional health insurance product is (expected to be) loss-making may an insurer request the supervisory authority, the National Bank of Belgium, for permission to increase premiums.39

In the Belgian case, the European Commission considered that the restrictions on increases in premium rates were contrary to the principle of freedom to set rates.45 In its ruling, the
As for the suitability of the restrictive Belgian regulation for the attainment of the objective it pursues, the European Commission expressed serious doubts.48 The Commission considered that it might prove difficult for the regulator to reject proposed increases in premium rates for loss-making additional health insurance products. If this were the case, premium increases would not be prevented and the consumer would not be protected against sharp, unforeseen increases in premium rates. In other words, the Commission had serious doubts about the effectiveness of the regulation.
4.1 Proportionality of the Contested Regulation
In the
What would be the consequences of applying these five criteria to the Slovenian and the Belgian cases?
-
Nature of additional health insurance: Both in Belgium and Slovenia, additional health insurance is not substitutive but complementary and supplementary. In Belgium, about half of total expenditure by additional health insurance is spent on providing access to a private hospital room. There are no studies available proving that the quality of care in a private room in a Belgian hospital is better than in a double or common room. In Slovenia, co-payments represent 85% of total reimbursement by additional health insurance. Therefore, as to this criterion, the Slovenian regulation may be considered more proportionate than the Belgian regulation.
-
Expenditure by additional health insurance as a share of total expenditure on healthcare: While additional health insurance covers 14.8 per cent of total expenditure on healthcare in Slovenia, the figure reaches only 4.4 per cent in Belgium (2014). In fact, the share of total health expenditure covered by additional health insurance in Belgium has dropped from 5.1 per cent in 2003 to 4.4 per cent in 2014. Over the same period, in Slovenia, there has been an increase from 13.9 per cent to 14.8 per cent.50 So far as this criterion is concerned, the Slovenian regulation may be considered more proportionate than the Belgian regulation.
-
Objective of public interest: Due to the existence of community rating in Slovenia, protecting consumers against sharp, unexpected increases in insurance premium rates equally serves the objective of granting access to additional health insurance, irrespective of age and health status (by keeping premium rates affordable) and the objective of protecting consumers who freely conclude their contract in a competitive market. This is not the case for the Belgian market. In Belgium, insurers are completely free to set premium rates for new clients. New clients who suffer from a pre-existing condition may have to pay an extra premium. Once a contract is concluded, given their higher initial premium, high risk clients will be more impacted by subsequent premium increases (in absolute terms). New clients are not protected by the restrictive regulation on increases in premium rates since this regulation is limited to existing contracts. Since the Slovenian regulation also affects access to additional health insurance, it appears to be more proportionate than the Belgian regulation.
-
Existence of a competitive insurance market: The Belgian health insurance market is more competitive than the Slovenian market. There is both a larger number of insurers and a bigger variety in premium levels in Belgium. In Slovenia, there are only 4 insurers, whose premium levels are close to each other,51 whereas in Belgium there are over 20 insurers.52 For these reasons, the Slovenian regulation may be more proportionate than the Belgian regulation as far as this criterion is concerned.
-
Alternative measure possible: In its reasoned opinion on the Belgian case, the European Commission put forward a number of alternative measures: better information for consumers underwriting additional health insurance; a framework for contested contractual clauses; an obligation to offer a standard contract with limited premiums to vulnerable groups (cf. the ‘Basistarif ’ offered by private basic health insurance in Germany); a limitation of the technical part of the premium (i.e., pure premium and security loadings) in combination with a more flexible framework for the commercial part of the premium (i.e., administrative and commercial costs); a risk equalisation system.53 However, some of these supposedly less restrictive measures may well be more restrictive than linking premium increases to a price index (e.g., an obligation to offer a standard contract with limited premiums to vulnerable groups).
Given that additional health insurance expenditure as a share of total healthcare expenditure is much larger in Slovenia and the Slovenian additional health insurance market is less competitive than the Belgian market, it is remarkable that the

5 Free Market or Regulation?
A clear indication of how the organisation of additional health insurance within the
According to the European Commission, consumers’ interests are best protected by promoting free market principles: ‘competition encourages enterprise and efficiency, creates a wider choice for consumers and helps reduce prices and improve quality’.68 However, according to Thomson and Mossialos, there is no evidence to suggest that the expected benefits of competition have, as yet, materialised in the private health insurance sector.69 Private health insurance premiums have risen rather than fallen, often faster than inflation in the health sector as a whole, while insurers’ expansion across national borders has been limited to cross-border mergers and acquisitions, rather than genuinely new entrants to the market.70,71
Equal access to healthcare is at the core of equity in health which implies that ideally everyone should have a fair opportunity to attain their full health potential and, more pragmatically, that no one should be disadvantaged from achieving this potential, if it can be avoided.72 The Constitution of the World Health Organisation sets out the following principle as ‘basic to the happiness, harmonious relations and security of all peoples’: ‘The enjoyment of the highest attainable standard of health is one of the fundamental rights of every human being without distinction of race, religion, political belief, economic or social condition’.73
Equity of access to healthcare services can be improved by defining essential healthcare services.74 Essential healthcare services should be made accessible to everyone within the healthcare system. The Committee on Choices in Health Care, the so-called Dunning Committee, established in 1990 in the Netherlands, has developed a set of four principles, to be applied successively, in order to delineate essential from non-essential healthcare services: necessity, effectiveness, efficiency, and individual responsibility. The principle of necessity is defined very broadly, basically meaning any treatment that is necessary to maintain or restore health, or to relieve suffering.75 With regard to the principle of effectiveness, only interventions where there is evidence for an effect are covered. The services to be covered are further narrowed down by those that give value for money, by only funding efficient services. Finally, services that are best dealt with by the individuals themselves are excluded (i.e., services that can easily be paid for by the individuals themselves).76
If additional health insurance really is so important that restrictive regulation is needed, would it not be better to integrate additional health insurance within the social security system? The poor, the sick and the old who cannot afford voluntary additional health insurance are not protected by government designed consumer protection rules regarding the additional health insurance market. As a consequence, regulation of additional health insurance protects only the well-off (or better-off) customers who can afford to buy additional health insurance. When additional health insurance covers essential healthcare, a more equitable result might be reached by integrating that care into the social security system rather than by developing restrictive regulation protecting only the well-off part of the population who can afford additional health insurance.
In Slovenia, where additional health insurance primarily covers co-payments, lower income groups might be better served by a decrease in co-payments or by direct subsidies rather than by introducing restrictive regulation for voluntary additional health insurance.
In Belgium, additional health insurance mainly covers hospital care. About half of the money reimbursed by additional health insurance relates to the price of a stay in a private hospital room. Since quality of care in a private room is no better than in a double or common room, it might be difficult to uphold the view that special protection from government is needed to secure access to private hospital rooms.
New health technology is often reimbursed by additional health insurance. From an equity point of view — if essential healthcare services are concerned — new health technology should be integrated in basic health insurance rather than protecting only those customers who can afford additional cover.
Additional health insurance also provides financial protection from co-payments. Traditionally, co-payments were introduced to reduce moral hazard.77 Co-payments are meant to prevent people from seeking medical care that may not be necessary. Apart from their traditional role, co-payments also allow the public sector to shift costs on to households.78 In countries where private additional health insurance covers co-payments, the scope of statutory coverage might erode over time and there are concerns about the fact that those who do not have additional health insurance may face financial and other barriers to accessing healthcare.79
If there is insufficient public funding to reduce co-payments and to integrate (new) health technology within the mandatory basic health insurance system, basic health insurance could be extended with private funding. Low income groups, who cannot afford private funding, could be subsidised. The French government has chosen this option. In 2014, 7.4 per cent of those covered by additional health insurance benefited from a public programme providing free coverage to the poorest (‘complementary universal health coverage’, ‘couverture maladie universelle complémentaire’ (
If all essential healthcare would be covered by an affordable basic health insurance scheme, there is no need to develop restrictive regulation for the voluntary additional health insurance market (covering non-essential healthcare).81 With all essential care being covered by the social security system, customers taking out voluntary health insurance would no more need special government protection than customers taking out home or car insurance.
In the Netherlands, the situation is clear-cut. According to the Dutch government, all essential healthcare is covered by mandatory basic health insurance. Voluntary additional health insurance, providing top-up cover for alternative medicine, dental care and physiotherapy, is not regulated by the government.82
However, as long as essential healthcare is not always reimbursed by mandatory basic health insurance and as long as statutory user charges (co-payments) remain quite substantial or fee supplements — extra billing — continue to exist, additional health insurance schemes may well be important for securing access to healthcare. In two
Free market and regulation need not be opposites. Competition does not exclude regulation. On the contrary, regulation can improve competition and help create a level playing field. Regulation can empower consumers, e.g., by creating more transparency (for instance, by obliging the use of standard clauses or even the use of standard contracts in additional health insurance). In the second half of the 1990s, the Office for Fair Trade (
A main obstacle for efficient and effective regulation is the information asymmetry between insurers and government. In Belgium, for instance, government regulation states that the medical index — used to adjust additional health insurance premiums to the evolution of healthcare costs — cannot be negative, even when cost evolution is negative. Such regulation may not be in the best interest of consumers. Another issue is that a medical index of this sort could act as a disincentive for insurance companies to reduce costs, because they know that in the end cost increases will be covered by the medical index. In this way, the application of medical indices could even have an inflationary effect.
When all essential care is included in the social security system and barriers to care (e.g., high co-payments) have been removed, the market for voluntary additional health insurance could be opened to private — for profit or not for profit — companies with real competition actively being fostered.
