Korea Health Insurance Surplus: 5-Year Streak, But Declining – 30 Trillion Won Reserve

January 28, 2026 discoverhiddenusacom Health

South Korea’s national health insurance system recorded its fifth consecutive year of surplus, with accumulated reserves exceeding 30 trillion won – a record high. The National Health Insurance Service (NHIS) reported total revenue of 102.8585 trillion won and total expenditures of 102.3589 trillion won for the past year, resulting in a current surplus of 499.6 billion won.

Sustained Surplus, Shrinking Margins

While the health insurance system has maintained a surplus for five years, the size of that surplus is decreasing. The surplus was 2.8 trillion won in 2021, increasing to 3.6 trillion won in 2022 and 4.1 trillion won in 2023. However, it dropped to 1.7 trillion won in 2024 and further decreased to last year’s 499.6 billion won – a 29.0% reduction from the previous year.

Revenue and Expenditure Details

Insurance premiums accounted for the majority of total revenue, reaching 87.2776 trillion won, a 4.0% increase year-over-year. Growth in premiums from employed individuals slowed due to a deceleration in the growth of the number of insured individuals and monthly wages, coupled with a two-year freeze on premium rates. However, a recovery in regional insurance premium growth, following a temporary decline due to 2024’s premium relief policies, helped boost overall premium revenue.

Did You Know? The accumulated health insurance reserves reached 30.2217 trillion won last year, surpassing the previous record of 29.7221 trillion won.

Government subsidies and other income also increased, by 2.7% and 4.1% respectively, reaching 12.4913 trillion won and 3.896 billion won. Strategic fund management in response to changing financial market conditions generated approximately 708.8 billion won in cash revenue.

Total expenditures were largely driven by insurance benefits, which totaled 101.6650 trillion won – an 8.4% increase from the previous year. This increase is attributed to adjustments in fee schedules, support for emergency medical services, and assistance with the structural transformation of tertiary hospitals. Other business expenses, including integrated collection surcharges, rose by 3.3% to 2.1783 trillion won. A prepayment of 1.5 trillion won to training hospitals in 2024, due to physician resignations, was fully repaid.

Future Outlook and Management Strategies

The NHIS recognizes the challenges posed by slowing economic growth, a declining working-age population, and planned government investments in essential medical services. To ensure the system’s sustainability, the NHIS plans to conduct a comprehensive review of its expenditure management system through analysis by the Appropriate Care Promotion Division. It also intends to introduce a special judicial police system to prevent financial losses due to illegal establishments and continue managing excessive outpatient utilization.

Expert Insight: The decreasing surplus, despite overall positive figures, highlights the growing pressures on the national health insurance system. Proactive financial management and efforts to control costs will be crucial as the system faces increasing demands and potential future deficits.

NHIS Director Jeong Gi-seok stated that a deficit is anticipated in the 2026 health insurance current surplus. He emphasized the need for meticulous expenditure management and the promotion of a healthy medical utilization culture to enhance the financial soundness of the health insurance system while pursuing national policy objectives.
