Supplementary insurance allows you to extend the benefits of
basic insurance and adapt them to your own needs. For example,
hospital insurance allows you to choose the comfort you want in your hospital room or you can take out
dental insurance for any unforeseen dental treatments. Unlike basic insurance, a health insurance provider can reject a supplementary coverage application. This means that, in the presence of a high health risk, supplementary insurance may not be granted to a person insured under basic insurance.
