Query: Please tell me about health insurance in South Korea. What financing approach is used for the primary coverage — e.g., all private insurers (and of those, a role for profit)? all public? a mix? Is separate supplemental insurance? What % of the population is uninsured? Does everyone have the same coverage (benefits + cost-sharing obligations)? How high are deductibles? How common is medical bankruptcy / debt? How common are access to care problems for financial reasons? What is annual health care spending per capita? (Feel free to compare to the US)
ChatGPT 4o:
South Korea’s healthcare system is primarily a publicly financed, single-payer model known as the National Health Insurance Service (NHIS). It offers universal coverage with a standardized benefits package, supplemented by private insurance options. Here’s an overview comparing key aspects with the U.S. system:
1. Financing and Structure
- Primary Coverage: Administered by the NHIS, a government-run entity under the Ministry of Health and Welfare.
- Funding:
- Payroll Contributions: Shared equally between employers and employees.
- Government Subsidies: Support for low-income and self-employed.
- Out-of-Pocket: Patients contribute through co-payments and services not covered by NHIS.
- Private Insurer Role: supplemental benefits and services.
2. Universal Coverage and Enrollment
- Coverage: ~97% of population enrolled in NHIS.
- Medical Aid Program: Covers the remaining 3% (low-income unable to pay in).
3. Benefits and Cost-Sharing
- Standardized Benefits: NHIS provides a uniform benefits package, ensuring equitable access to healthcare services.
- Deductibles: No deductible system akin to the US.
- Co-Payments:
- Inpatient Care: Usually 20%.
- Outpatient Care: 30-60%, depending on care level & facility type.
- Exemptions: Low-income, age <6 and >65, cancer / rare diseases, disabled.
4. Supplemental Private Insurance
- Purpose: To cover services not included in NHIS, such as certain advanced diagnostics, private hospital rooms, and alternative treatments.
- Enrollment: Many individuals opt for PHI to reduce out-of-pocket expenses and access a broader range of services.
5. Financial Protection and Access
- Medical Bankruptcy: Rare due to the comprehensive coverage provided by NHIS and Medical Aid Program.
- Access Issues: While the system provides broad access, some individuals may experience financial strain due to services not covered by NHIS or high co-payments.
6. Health Expenditure
- $4,570 per capita (2022).
- US: $13,432 per capita (2023)

My wife and I are in Seoul, the capital of South Korea, on holiday. Our first three days have been wonderful, in this vibrant, easy-to-navigate, safe, and friendly city. We’ve had terrific conversations with quite a few people, despite our nearly non-existent Korean. Many locals manage well in English, and love to discuss their country and ours. They seem pleased to discover that we know a bit about Korean history and culture, gleaned from reading and Korean TV dramas. As far as we can tell, the culture combines diligence about work and family obligations with a sense of calm. We see consistent evidence of high trust, with valuable items (even a vendor’s cash box) left unguarded.
Of course, I’m no sociologist, and our impressions are preliminary and tentative. Still, we like what we’ve seen so far. Of note, South Korea has a thriving, free-market economy. And a thriving democracy –a popular uprising suppressed an attempted military coup by the president in December 2024.
So, naturally, I had to inquire about how health insurance works here. I know some people are skeptical about ChatGPT and other AI large language models. However, the latest versions are, based on my scrutiny, reliable sources of nuanced information. A carefully phrased query yields a highly edifying response.
As you see in the excerpt, South Korea relies on single payer. The result is high access, low costs, and impressive longevity. I can’t prove it, but I believe that universal public insurance also contributes to the high level of friendliness, calm, and trust that we’ve seen so far. Certainly, there are no significant downsides to providing universal insurance. When, oh when, will the US learn from the myriad exemplary insurance practices around the world?
