Health Insurance Korea: 5 Visas Covered From Day One, and the Cost of Skipping It

Bottom line: If you're on a student visa (D-2), a pre-college study visa (D-4-3), a non-professional employment visa (E-9), permanent residency (F-5), or a marriage-migrant visa (F-6), you get local National Health Insurance (NHI) coverage from your very first day in Korea. Everyone else on a long-term visa gets auto-enrolled the day after they complete six months in the country — you don't have to apply, the service does it for you. Tourists and anyone on a stay of 90 days or less aren't covered by this at all.

If you didn't know: Falling behind on premiums while you're supposed to be covered doesn't trigger an instant fine, but unpaid premiums can count against you when your visa extension or status change is reviewed. Go to a hospital with no coverage and you pay the full, non-discounted rate — even a basic cold visit costs noticeably more than it would with insurance. And once you're enrolled, leaving Korea for a single continuous stretch of one month (30 days) or more cancels your coverage the next day — re-enrolling later can mean paying back premiums for the whole time you were gone.
