It is easy to assume each visa comes with its own required insurance policy. What actually differs is not the type of insurance but the route by which you enter the National Health Insurance scheme — whether you arrive through employment or through your status of stay.
Employment and status of stay are the two tests
If you are employed by a company or school, you are enrolled as an employee subscriber, with the premium split evenly between you and your employer. Without an employment relationship you become a local subscriber. The general rule for foreign residents is that mandatory local-subscriber enrolment attaches to six months of residence — but several statuses are enrolled straight away and are the common exception, not a footnote.
If you are here to study, the six-month rule does not apply to you
For the study status D-2, and for D-4-3 (primary, middle and high school students), enrolment takes effect from the date of alien registration on first entry, and from the date of re-entry if you already hold alien registration. There is no six-month wait. The six-month wait applies to general training under D-4 other than D-4-3, which is enrolled six months after the date of entry. Premiums for a student are assessed on the individual as a household of one; a reduction scheme applies and both the basis and the level of reduction have been revised in the past, so confirm the figure that currently applies to you with the National Health Insurance Service on 1577-1000 (foreign language line 033-811-2000). Some universities brief incoming students on this or contribute toward the cost, so ask your international office as well.
If you are employed, as instructors usually are
You should be registered as an employee subscriber from the point employment begins. Some academies additionally provide a group policy. That policy is separate from National Health Insurance and is not a legal requirement, which is the source of a recurring problem: an employer provides private cover only and never files the health insurance enrolment. Check your own enrolment status rather than assuming the group policy means it was handled.
What national coverage does not reach
Even with National Health Insurance, dental work, traditional Korean medicine and non-covered procedures leave real costs with you. If you are planning orthodontic treatment or expect frequent visits, supplementary indemnity insurance or a dental rider is worth pricing. Before buying, check whether your employer or university already provides group cover, because overlapping policies frequently add cost without adding protection. You can check your own enrolment through the four social insurances information portal or directly with the service.
