5th Gen Korean Health Insurance 2026: Avoid Premium Hikes

Starting April 2026, South Korea will introduce its 5th generation of comprehensive health insurance, coinciding with an anticipated 20% premium increase for the 4th generation. If you're generally healthy and use medical services infrequently, switching to the 5th generation plan could significantly reduce your insurance costs. This is not financial advice. Consult a licensed financial advisor.

What's New with 5th Gen Korean Health Insurance?

The 5th generation health insurance plan is designed with a 'spend less, pay less' philosophy, aiming to lower premium burdens for healthy individuals. The most significant change is the expansion of the deductible for non-covered (non-급여) medical services from 30% to a maximum of 50%. While this might increase out-of-pocket expenses for those frequently using services like physical therapy or vitamin injections, it offers substantial savings for infrequent users. Furthermore, the system that differentiates premiums based on non-covered service usage is being strengthened. This means those who use fewer non-covered services will receive greater discounts, while those who use more will face higher surcharges. For instance, under the 4th generation plan, premiums could be surcharged by up to 300% based on non-covered service utilization, so caution is advised.

Why the 20% Premium Hike for 4th Gen Insurance? And When to Switch?

The projected 20% premium increase for 4th generation comprehensive health insurance starting in 2026 is primarily due to rising loss ratios caused by excessive non-covered medical treatments. While initially attractive for their low premiums, the higher-than-expected claims have led insurers to implement these increases. This has understandably led to dissatisfaction among 4th generation policyholders, prompting many to consider switching to the 5th generation plan. However, a transition to the 5th generation isn't beneficial for everyone. If you have chronic health conditions requiring regular hospital visits or frequently undergo non-covered treatments like physical therapy, your out-of-pocket expenses could increase significantly due to the higher deductible. Therefore, before making a switch, it's crucial to review your non-covered medical usage over the past year and carefully consider the value of your existing policy, especially if you have an older plan with broader coverage, such as the 1st generation 'blanket coverage' plans.
