National Health Insurance in Korea for Americans

Korea's National Health Insurance is cheap by American standards, and for most foreign residents it isn't a choice. Skip the bills and you may hear about it at your next visa extension.

The short version

If you work for a Korean employer, you're enrolled as an employee subscriber from day one, and your employer pays half [1][2].
Everyone else on a qualifying status is enrolled automatically as a regional (self-employed) subscriber once they've lived in Korea for six months. Students on D-2 and marriage migrants on F-6 join at registration [2].
In 2026 the contribution rate for employees is 7.19% of pay, split down the middle [4].
Foreign regional subscribers pay at least the national average premium. For 2026 that's reported as KRW 158,630 a month (about USD 119), long-term care included [1][5].
Unpaid premiums can mean paying full price at the hospital, and immigration may limit your visa extension [3][6].

USD conversions use the Federal Reserve H.10 rate of October 30, 2026 (USD 1 = KRW 1,333.99).

How the system works

Korea runs one public insurer, the National Health Insurance Service (NHIS). There's no menu of plans, no open enrollment season and no network to check. Almost every clinic and hospital in the country takes it. You pay a share of the bill at the counter, and NHIS covers the rest. Think Medicare for everyone, with copays that won't make you wince the way an emergency room bill back home can.

There are two ways in, and which one you're in decides how your premium is figured.

	Employee subscriber	Regional (self-employed) subscriber
Who	Registered foreigners working at a covered workplace, plus public officials and school staff [1][2]	Everyone else on a qualifying status, after six months' residence [1][2]
When it starts	From your first day of work; employer reports within 14 days [2]	Automatically after six months, no separate report needed [2]
Premium	Monthly wage x contribution rate, 50/50 with your employer [1][2]	Points-based, but never less than the national average for foreigners [1]
2026 numbers	7.19% of wages, so about 3.6% from you [4]	Reported minimum of KRW 158,630 a month (about USD 119) [5]
Dependents	Spouse, kids and some parents can be added, within income limits [1][2]	Billed by household [1][2]

Employee subscribers

If you're on a payroll at a covered workplace, coverage starts with the job. The employer files your enrollment within 14 days of hiring you, and your share of the premium comes straight out of your paycheck, retroactive to your start date [1][2]. Day laborers hired for less than a month and people working under 60 hours a month are generally excluded [2].

In 2026 the health insurance contribution rate is 7.19%, up 0.1 percentage point from 2025, as the Health Insurance Policy Deliberation Committee decided and the government's Korea.kr news service reported [4]. You and your employer each pay half. A long-term care premium is added on top, calculated as a percentage of the health premium. You'll see the two as separate lines on your pay stub.

There's one escape hatch for employees. If you can prove you already have equivalent coverage through a foreign insurer, a foreign law or your employment contract, you can apply for exclusion with the Employee Health Insurance Withdrawal Application. File within 14 days of being enrolled and NHIS treats you as never having joined [1]. That's mostly relevant to people seconded by a US company with a global health plan.

Regional subscribers

Freelancers, investors, retirees, spouses of foreigners and others without a Korean employer are enrolled automatically as regional subscribers once they've lived here six months [2]. The six-month rule has applied to foreign residents since July 16, 2019 [1][3]. Students on D-2 visas and marriage migrants on F-6 are covered from the start, as soon as they register with immigration [2].

The regional premium is calculated from income and property, using a point system. The catch for foreigners: if your calculated premium comes in below the national average, you pay the average [1]. Most newcomers with little Korean income or property land right on that floor.

For 2026, Banksalad, a Korean personal finance service, reports the floor for general foreign regional subscribers as KRW 158,630 a month (about USD 119). That's KRW 140,210 for health insurance plus KRW 18,420 for long-term care [5]. It's not Obamacare-marketplace money, but it adds up over a year, and the bill comes whether or not you see a doctor.

Some groups pay less. NHIS lists reductions of 50% for D-2 and D-4 students and F-4 overseas-Korean students since March 2023, and 30% for D-6 religious workers and some humanitarian statuses [1]. Island and remote-area residents get reductions too [1].

Adding your family

On the employee side, a spouse, children and parents (yours or your spouse's) can be listed as dependents if they rely on you and meet income and property limits. NHIS says total annual income must be under KRW 20 million (about USD 15,000) [1].

For foreign families, the paperwork is the hard part. NHIS wants your ARC plus a foreign-issued family document showing at least two identifying details, such as name and date of birth. That means a US marriage or birth certificate with an apostille, a notarized Korean translation, and a date within nine months of the apostille [1]. Get the apostilles done stateside before you fly if you can. Regional subscribers can be billed as a household with proof of the family relationship [1].

Unpaid premiums and your visa

Here's where Americans get caught. Back home, a skipped premium usually just means a canceled policy. In Korea, it can follow you to the immigration counter.

At the hospital. Unpaid premiums mean no coverage, so you pay the full cost of treatment yourself [3]. Banksalad notes that falling behind by a month or more can trigger this, though paying the overdue amount by the deadline on the NHIS notice can restore coverage [5].
At immigration. When the six-month rule started in 2019, the government said foreigners with unpaid premiums could have visa extensions limited to up to six months [3]. The Seoul Immigration Office's own guide still warns that unpaid premiums can lead to "restrictions in extending your period of stay" [6]. Banksalad adds that arrears information is passed to the Ministry of Justice [5].

So treat the NHIS bill like rent. Set up automatic payment from your Korean bank account, and if you leave Korea for a long stretch, check with NHIS how your coverage and billing will be handled while you're gone.

Using it at the doctor's office

Bring your ARC. Clinics look you up by your registration number.
Start small. Neighborhood clinics handle colds, prescriptions and checkups. Big university hospitals are for specialists and serious cases.
Pay your share at the desk. You'll pay the copay before you leave, then take any prescription to a pharmacy next door.
Keep the receipts. They help if you claim on a private top-up policy or a US plan.

NHIS has a foreign-language helpline at 033-811-2000, plus its main line at 1577-1000 [2][3].

The American side

Korean coverage doesn't replace anything back home, and vice versa. Medicare generally doesn't pay for care outside the United States, so if you're 65 or close to it, think hard about Part B enrollment before you skip it, since late penalties can stick for life. If your employer is a US company, ask whether your stateside plan covers you abroad or whether you'll be enrolled in NHIS through a Korean entity. And if a premium dispute is threatening a visa renewal, sort it out with NHIS before your immigration appointment, not after.
