Regulations of the European Parliament and of the Council coordinating social security systems provide that person insured in one EU Member State is entitled to receive necessary healthcare or, in certain circumstances, planned treatment during a stay in another EU Member State. In addition, a person who is insured in one EU Member State but resides in another, is entitled to free healthcare in the country of residence. The state where the person is covered by social insurance is responsible for paying for these health care services. These rules are also applicable in Norway, Iceland, Liechtenstein, Switzerland and the United Kingdom.
