Health Insurance (NHIS) Guide for Foreigners — Mandatory Enrollment, Premiums, Hospital Use

One day a "health insurance premium bill" shows up in your mailbox. It lists an amount over ₩150,000 a month. You never signed up, so why do you have to pay it, how do you actually go to a hospital, and can missing payments really block your visa extension? These are exactly the questions foreigners in Korea search for most.

Korea's National Health Insurance Service (NHIS) applies to foreigners too. That said, your eligibility, premium, and the link to your residency all depend on your visa type, income, assets, and entry date, and the rules change often. What follows is a broad overview as of June 2026, and you should always confirm your individual amounts and eligibility through an official channel (see the reference note at the bottom).

1. Foreigners Are Enrolled by Mandate Too — Automatically, Without Applying

Korea's health insurance is a mandatory (automatic) enrollment for foreigners too. You don't join by submitting an application; once you meet the requirements, you become an enrollee automatically.

Since July 2019, foreigners who complete foreigner registration and reside in Korea for 6 months or more are subject to mandatory enrollment in health insurance and long-term care insurance. In principle there is no "I'd rather not enroll" option. If you work for a company, coverage starts the moment you're hired; otherwise, you're enrolled automatically once a certain period has passed after entry.

Enrollment falls into two broad tracks.

For employer-based subscribers, coverage applies from your hire date and the company covers half, so there's almost nothing you need to do separately. The ones who receive a bill directly are mainly individual (regional) subscribers.

2. When Does Enrollment Start — 6 Months After Entry, With Visa-Based Exceptions

For individual subscribers, the rule is that enrollment begins only after 6 months have passed from your entry date (based on the April 2024 implementation). However, the visas below may qualify for an exception with immediate or early enrollment from the registration date (official confirmation required).

• Some student visas such as D-2 (Study) and D-4-3: enrolled from the entry/registration date
• E-9 (Non-Professional Employment), F-5 (Permanent Residence), F-6 (Marriage Immigration), etc.: applied from the registration date
• Other general residents: automatically enrolled as individual subscribers once 6 months have passed after entry

The ARC (Alien Registration Card) and the F-4 residence report are separate systems, and the enrollment timing differs by visa and residency status. Rather than deciding on your own which category you fall into, it's best to confirm with NHIS foreigner support. It usually takes over a month to receive your ARC, so asking in advance about how to handle medical care and insurance during that gap will give you peace of mind.

3. 2026 Premiums — Employer-Based vs. Individual Subscribers

Employer-Based Subscribers (Company Employees)

The 2026 health insurance premium rate is 7.19% of monthly wages (up from 7.09% in 2023–2025, the first increase in three years), and this is split evenly between the employer and the employee (3.595% each) (a long-term care insurance premium is added separately). It's automatically deducted from your pay slip, so there's almost nothing you need to pay on your own.

Individual Subscribers (Other Foreigners)

For individual subscribers, the premium is calculated by scoring your income, assets, vehicles, and so on. However, a "minimum premium (floor)" applies to foreign individual subscribers. The key point is that if the calculated value falls below the average, you're required to pay a premium at roughly the average level for all subscribers.

For 2026, the minimum premium for overseas Korean and foreign individual subscribers is ₩158,630 per month (up about 3.8% from ₩152,790 in 2025). Your exact billed amount varies by individual depending on income and assets, so official confirmation is needed.

International students (D-2, etc.) often qualify for about a 50% reduction off the average premium (for 2026 student premiums, check your school's notices and NHIS guidance).

The claim that "foreigners always pay the minimum premium" is a misunderstanding. If you have higher income or assets, more than that is charged, and employer-based subscribers are billed based on salary. Check your own billed amount with NHIS.

4. How to Use Hospitals and Pharmacies — Coverage Scope

Once you're an enrollee, you can receive care at Korean hospitals, clinics, and pharmacies at health-insurance-covered prices.

1. When you check in, just show your Alien Registration Card (ARC) or ID.
2. Once your eligibility is confirmed, you pay only a partial out-of-pocket amount, and health insurance covers the rest.
3. Typically, health insurance covers about 80% for inpatient care, and 30–70% for outpatient care depending on the item and institution (varies by item and institution).

Non-covered services (cosmetic procedures, certain tests, etc.) are excluded from coverage, and out-of-pocket rates may change as the system is reformed.

5. Paying Premiums and Extending Your Visa — Why Missed Payments Are Risky

Individual subscribers pay each month's premium by the 10th of the following month (via automatic transfer, virtual account, card, etc.).

If unpaid amounts pile up, it can affect your visa extension (residency extension). Guidance states that if you fall behind by a certain amount and for a certain period, it links to the Ministry of Justice immigration system, and you may face restrictions when applying for an extension.

"I'll just pay it all off later" is the riskiest choice. If money is tight, don't let it slide — the safer move is to first consult NHIS about whether installment payment or a reduction is possible.

Decisions about residency and visas are made based on your individual situation. If you've built up arrears or are worried about your extension, check with both immigration (HiKorea / 1345) and NHIS. This article is general guidance only, not legal or administrative advice.

Frequently Asked Questions (FAQ)

Q1. I never applied, but I got a premium bill. Why? A. Korea's health insurance is mandatory (automatic) for foreigners too, so once you meet the requirements you're enrolled automatically without applying. Confirm your eligibility and enrollment date with NHIS foreigner support.

Q2. Can I be enrolled even before 6 months are up? A. It depends on your visa. Some, such as D-2 (Study), E-9, F-5, and F-6, are enrolled from the registration date, while general residents are enrolled once 6 months have passed after entry as a rule (official confirmation required).

Q3. The premium is too expensive. Can I reduce it? A. There may be case-by-case options such as student reductions, installment payments, or family aggregation. Rather than guessing on your own, consulting NHIS directly is the accurate way to find out.

Q4. Will missing premium payments block my visa extension? A. Guidance states that if arrears build up beyond a certain level, it can affect the review of your residency extension. The exact criteria and decisions fall under the immigration authorities, so check with HiKorea / 1345 and NHIS.

Q5. How do I get it applied at the hospital? A. When you check in, show your Alien Registration Card, and after your eligibility is confirmed you only pay the out-of-pocket amount. The coverage scope and out-of-pocket rate vary by item, institution, and time.
