The Ministry of Health has presented a series of measures to prevent fraud in changing health insurance. With the new legislation, the resort responds to the number of submissions sent by insured persons to the Health Care Supervisory Authority. In 2021 alone, the submissions concerned up to 10 000 inhabitants of Slovakia. The Ministry of Health has presented rules for the efficient use of health levies. One of the fundamental changes to the new legislation is the transparency of the insurance system. The current set-up has proved to be unsatisfactory in practice - it underlines the number of submissions to the Health Care Supervisory Authority. In their submissions, insured persons often state that a change in the health insurance undertaking occurred without their knowledge, arguing that they did not sign the application, that the signature on the application was forged and so on. Alternatively, they were provided with misleading to false information on the part of the persons who filed the application. Often insured persons were convinced that this was a public opinion poll or a poll, says Renáta Blah, Chairman of the Health Care Supervisory Authority. Several measures should enter into force from next year which minimise the scope for similar illegal overinsurance. The new legislation will lay down clear rules for submitting applications in person, by post or by electronic means. It will not be possible, for example, to sign applications to health insurance companies at railway stations, shopping centres or other places where it is not possible for the insured person to obtain the necessary information or to assess all aspects relevant. Pre-insurance can be closed directly at the insurance company's workplace, i.e. outside various intermediaries. When submitting applications by post or electronic means, the necessary particulars, including a certified signature, shall be clearly identified in order to minimise the scope for suspected fraudulent overinsurance. Last but not least, the new legislation will also introduce the Institute of Acceptance Letter from the previous health insurance company. By letter, the insured person informs the current insurance undertaking of the interest to change the insurance undertaking. It is this step that minimises the risk of a change occurring without the insured person's knowledge.
