Before I get sick, what should I know about seeking medical care in your city as an expat?
In the event of a medical emergency, it's best to take along a Korean-speaking person if possible, as hospitals or clinics English-speaking skills. Alternatively, you can write out your medical symptoms and/or condition in English. 

A number of hospitals in Seoul have clinics staffed by English-speaking physicians and nurses who can coordinate appointments the doctor has set up or been hired in an international clinic mainly because he/she trained abroad (usually North America However, the doctors are very willing to connect you with a specialist if you need one and will interpret for you, either directly 

1. Koreans do not have the same sense of privacy that Westerners do, so don't be embarrassed if the doctor asks to examine is an issue for you, you can ask to have a screen put up.
2. The wait time for medical treatment in hospitals can be quite long, even in the emergency unit.
3. In an emergency, you should take some cash with you (at least W500,000-W1,000,000) because some hospitals accept ATM machines located throughout most hospitals.
4. An international medical insurance card is not recognized as a form of pre-payment. You will have to pay your medical discharged. If you have global coverage, you can then submit the receipt to them for reimbursement. Some private hospitals accept National Health Insurance and while this is allegedly not legal, there is little that one can apparently do. As long as can enroll in the National Health Insurance plan; if your employer does not provide coverage, you can enroll yourself. Compared policy rates in some Western countries, the cost is not prohibitive.
5. If you are admitted to the hospital through the international clinic, your bill will likely be higher than if you had gone directly of the hospital’s other departments.
6. Korean physicians sometimes give the worst-case prognosis first and then go on to the less serious ones. Don’t panic, just a question of style and culture.
