The Global Health Insurance Card (GHIC) has replaced the European Health Insurance Card (EHIC). This card means you'll receive emergency and necessary state healthcare in EU countries as though you were a local citizen.
However, the GHIC isn’t a substitute for Travel Insurance. It doesn't cover you for:
the costs of rescue and repatriation (an air ambulance from Spain back to the UK costs £10,000 or more)
lost or stolen property such as passports, baggage or precious items
losses from trip cancellation, Cutting your Trip Short and interruption
extra travel and accommodation costs due to illness
any medical treatment needed outside of the EU
