If you're an EU citizen or from Switzerland, Iceland, Norway or Liechtenstein, the European Health Insurance Card will cover you for emergency health care or in the case of accident while in European Economic Area (EEA) countries, which include Denmark, Finland, Norway and Sweden.
Note that Greenland isn't part of the EEA but is covered by a separate reciprocal health-care agreement with the UK.
Citizens of other countries should find out if there is a reciprocal arrangement for free medical care between their country and the country visited. For travel to Arctic North America or Arctic Russia you should take out health insurance. If you do need health insurance, strongly consider a policy that covers you for the worst possible scenario, such as an accident requiring emergency evacuation. Find out in advance if your insurance plan will make payments directly to providers or reimburse you later for overseas health expenditures. The former option is generally preferable, as it doesn't require you to pay out of pocket in a foreign country.
