Find out in advance if your insurance plan will make payments directly to providers or reimburse you later for overseas health expenditures. ( In Turkey doctors generally expect payment in cash). If you are required to pay upfront, make sure you keep all documentation. Some policies ask you to call a centre in your home country (reverse charges) for an immediate assessment of your problem. It is also worth ensuring your travel insurance will cover ambulances or transport either home or to better medical facilities elsewhere. Not all insurance covers emergency medical evacuation home by plane or to a hospital in a major city, which may be the only way to get medical attention in a serious emergency.
Your travel insurance will not usually cover you for anything other than emergency dental treatment.
