Not sure what this means to those on tourist visas? OK they are still technically covered in the UK but this isn't much use if you need emergency treatment in Turkey. So - as they are not residents they cannot apply for Turkish Health Care. Travel insurance is a big no-no as it normally only covers you for 30 days maximum (and I guess they would wriggle out anyway if they found you have been 'living' in another country). Private medical insurance might be an option but it's costly and how many have it?
S0 - you go to the hospital and they ask if you are a tourist or resident. What do you say? Will you get free treatment in the future?
