The Generational Lottery: Why 1st Generation Indemnity Insurance Is a Financial Asset
In the landscape of South Korean health insurance, not all policies are created equal. For those lucky enough to hold a “1st Generation” indemnity health insurance policy—often referred to as sil-bo-hum—the coverage represents more than just medical security; it’s a significant financial asset. While newer policies offer lower premiums, the legacy benefits of the first generation are nearly impossible to replicate in today’s market.

Understanding the strategic value of these older policies is essential for policyholders and their families. Whether you inherited this policy from your parents or have maintained it for decades, knowing when to hold on and when to pivot is a critical financial decision.
What Exactly Is 1st Generation Indemnity Insurance?
Indemnity health insurance in South Korea is designed to cover the actual expenses incurred for medical treatment that aren’t covered by the National Health Insurance Service (NHIS). These policies are categorized by “generations” based on when they were issued, with the 1st Generation typically referring to policies sold before October 2009.
The defining characteristic of 1st Generation insurance is its generosity. Unlike modern plans, these early policies often featured 100% reimbursement for medical expenses, meaning the policyholder paid virtually nothing out of pocket for covered treatments. This “zero-deductible” structure is the primary reason these policies are so highly prized today.
The Strategic Advantage: Why It’s a “Parental Gift”
It’s common to see young adults express gratitude to parents who signed them up for these plans in childhood. From a business and risk-management perspective, this is a brilliant move for several reasons:

- Comprehensive Coverage: 1st Generation plans often cover a wider array of treatments and procedures with fewer restrictions than current versions.
- Minimal Out-of-Pocket Costs: While 4th Generation plans require significant co-payments (deductibles), 1st Generation plans often eliminate them entirely, protecting the policyholder from high medical bills during major health crises.
- Broad Claim Eligibility: Because the terms were written in a less restrictive era, many treatments that insurance companies now fight to exempt were easily covered under the original 1st Generation terms.
The Trade-Off: The Cost of Superior Coverage
The “gold mine” of 1st Generation insurance comes with a significant catch: premium escalation.

Insurance companies have realized that 1st Generation policies are loss-leaders. Because the payouts are so high and the deductibles so low, insurers frequently raise premiums for these specific policyholders to offset their losses. As you age, the cost of maintaining a 1st Generation plan can skyrocket, sometimes becoming a burden that outweighs the benefit of the 100% coverage.
Comparison: 1st Generation vs. 4th Generation
For those considering a “conversion” to a newer plan, it’s important to weigh the trade-offs. The 4th Generation plan, the current standard, operates on a “pay-as-you-go” model.
| Feature | 1st Generation (Pre-Oct 2009) | 4th Generation (Current) |
|---|---|---|
| Reimbursement Rate | Often 100% | Lower (Higher co-payments) |
| Monthly Premiums | High (and rising rapidly) | Low and stable |
| Deductibles | Very low or zero | Significant per visit/treatment |
| Premium Structure | Fixed by age/renewal cycle | Adjusts based on individual usage |
Key Takeaways for Policyholders
- Audit Your Policy: Check the issuance date. If it’s before October 2009, you likely hold a 1st Generation plan.
- Evaluate Your Health: If you have a chronic condition or expect frequent medical treatments, the 1st Generation plan’s high premiums are usually worth the cost due to the 100% reimbursement.
- Monitor the “Premium Cliff”: Be prepared for sharp increases in cost as you hit new age brackets.
- Consult Before Converting: Once you switch from a 1st Generation plan to a newer one, you can never go back. The decision is permanent.
Final Analysis
1st Generation indemnity insurance is a relic of a more generous insurance era. While the rising premiums are a legitimate concern, the sheer breadth of coverage provides a level of financial security that modern plans cannot match. For the healthy individual, a switch to the 4th Generation might save money; however, for anyone with significant medical needs, the 1st Generation policy remains one of the most valuable financial hedges a person can own.
