Yes, hospitalization following an accident is covered worldwide. You will still be entitled to hospitalization benefits if you are admitted to a foreign hospital (outside of Spain) as an inpatient on the advice of a doctor for more than 24 hours and due to an accident. It's however important that you go to a legally registered hospital.
Hospital is defined in our Policy General Conditions (page 4) as:
A legally registered establishment for ill or injured persons, which provides:
a) Medical and surgical treatment; and
b) 24 hours nursing care by registered nurses.
This does not include:
• a convalescent, self-care or rest home;
• a hospital department which has the role of a convalescent or nursing home;
• a hospice; or
• a mental health hospital.
