South Korea’s Ministry of Land, Infrastructure and Transport announced a revised enforcement decree for the Guarantee of Automobile Accident Compensation Act, introducing stricter medical verification standards for minor traffic accident injuries commonly known as the 8-week rule. Under the regulatory update, medical treatment exceeding eight weeks for minor injuries—classified as Grade 12 to 14 under the country’s injury rating system—will require additional documentation and diagnostic certification from attending physicians to prevent prolonged insurance claims.
The policy adjustment arrives as South Korea’s automobile insurance landscape faces mounting financial pressure from escalating payouts. According to industry data, despite a decrease in the overall volume of minor traffic accident patients, total medical expenses for these claims surged by approximately 400 billion won over a comparable reporting period, driving up overall insurance loss ratios.
Government officials and industry stakeholders structured the regulatory reform to curb rising insurance premiums driven by extended treatment durations for minor soft-tissue injuries. Ministry officials emphasized that the measure aims to protect the sustainability of the automobile insurance pool while ensuring that genuinely injured motorists receive necessary medical care without administrative disruption.
Background on South Korea’s Automobile Insurance Reform
For years, South Korea’s automobile insurance system permitted claimants with minor injuries, such as simple sprains or strains, to receive sustained medical treatment funded entirely by the at-fault driver’s insurance provider without strict periodic checkpoints. Critics and insurance industry associations argued this open-ended structure incentivized prolonged hospital stays and unnecessary outpatient visits, contributing significantly to rising insurance liabilities.
The Ministry of Land, Infrastructure and Transport initiated the legislative overhaul to establish clearer clinical boundaries. By implementing the 8-week threshold, regulators require patients requiring treatment past the two-month mark to submit formal diagnostic proof confirming the clinical necessity of extended care. Industry analysts note that similar regulatory adjustments in other markets have successfully curbed fraudulent or exaggerated claims while maintaining legitimate patient access.
Financial Impact and Industry Data
The financial rationale behind the enforcement decree centers on a widening gap between patient volume and total expenditure. Insurance data reviewed by regulatory authorities revealed that even as the absolute count of minor injury claimants dipped slightly year-over-year, total treatment costs climbed by roughly 400 billion won.
This cost divergence placed heavy burdens on non-life insurance companies, eventually filtering down into higher insurance premium rates for everyday vehicle owners. By curbing prolonged, low-acuity treatments, the government expects to stabilize loss ratios and prevent further systemic cost increases across the domestic insurance market.
Implementation and Next Steps
With the Cabinet approval finalized, insurers, medical institutions, and regulatory bodies are preparing for full administrative integration. Hospitals and clinics specializing in traffic accident rehabilitation must adapt their documentation procedures to issue the required diagnostic verifications for patients approaching the 8-week limit.
The Ministry of Land, Infrastructure and Transport plans to monitor the implementation phase closely, evaluating its effectiveness in reducing unnecessary medical expenditures and stabilizing insurance premiums over the subsequent fiscal quarters.
