South Korea medical expenditure and insurance trends
Overview
South Korea’s national medical expenditure reached a record high of approximately 225 trillion won in 2025, representing 8.4% of the nation’s GDP. This total includes a rise in primary surgical procedures and costs, driven by new insurance structures and holiday-related surcharges. Under the 4th generation indemnity insurance system, high non-reimbursable expenses can trigger premium surcharges of up to 300%. Additionally, medical costs rise during public holidays due to a 30% surcharge on basic examination fees, which can cause out-of-pocket expenses for seniors to jump by approximately 2.5 times.
Fiscal stability is increasingly threatened. The National Health Insurance Service (NHIS) faces a projected debt crisis, with its debt-to-equity ratio expected to climb from 71.2% in 2026 to 107.4% by 2030. Financial leakage is also a concern; high-value premium arrears (exceeding 10 million won) more than doubled between late 2022 and July 2024, reaching 409.3 billion won. Furthermore, investigations identified approximately 138.9 billion won in fraudulent health insurance claims across 3,004 institutions over five years. Recent data also revealed that approximately 4.25 trillion won in premiums were overcharged or incorrectly paid over a five-year period.
The proposed 2027 budget has come under scrutiny because the projected government support rate from the general account is 12.5%, failing to meet the 14% statutory requirement. While total government contributions are expected to reach a record 13.8 trillion won, the shortfall has prompted protests from the National Health Insurance Workers' Union. Meanwhile, the financial balance for foreign nationals reached a record surplus of over 1 trillion won, though Chinese nationals recorded a deficit of 40.9 billion won, reigniting debates over the reciprocity principle.
