Silson Insurance: Korea's Medical Indemnity Policy
Just like expensing a business trip where your employer reimburses the exact amount on your receipts, this policy pays you back for the actual out-of-pocket medical bills you paid at the hospital.
Definition A private health insurance policy that reimburses a major portion of the actual out-of-pocket expenses listed on your hospital receipts. In South Korea, it bridges the gap by covering medical treatments not paid for by the National Health Insurance (NHI), easing the financial burden of unexpected healthcare costs.
It reimburses you based on your actual receipts
Think about submitting an expense report after a business trip. You submit your receipts and get reimbursed only for the exact amount you spentโnever a dollar more.
Traditional fixed-benefit insurance policies pay a lump-sum amount (e.g., $25,000 / 30 million KRW) upon diagnosis regardless of your actual hospital bill. In contrast, indemnity health insurance (known in Korea as Silson or Silbi) reimburses the actual out-of-pocket costs listed on your hospital receipts.
For example, if your clinic visit and diagnostic tests cost you 100,000 KRW (about $75) out of pocket, the insurer will deposit around 80,000 to 90,000 KRW back into your bank account after deducting a predetermined copay.
Because it covers real, quantifiable financial losses, it serves as an essential safety net for everything from minor outpatient visits to major hospitalizations.
It covers non-covered services excluded from public healthcare
Looking closely at a hospital bill in Korea, medical costs are divided into two main categories: "covered" (geub-yeo) services, partially funded by the public National Health Insurance, and "non-covered" (bi-geub-yeo) services, which patients must pay 100% out of pocket.
Advanced physical therapy, targeted injections, and specialized imaging scans often fall under these non-covered services. Because hospitals set their own pricing for non-covered care, bills can quickly add up to hundreds or thousands of dollars.
Silson insurance plays a crucial role by covering these costly non-covered medical expenses. By stepping in where public insurance ends, private insurers share the heavy financial burden.
As a result, layering private indemnity insurance on top of universal public healthcare creates a robust two-tier safety net for household finances.
A closer look: Why doesn't it reimburse 100% of the bill?
Indemnity policies do not reimburse 100% of your bill unconditionally. Every policy includes a mandatory copay or deductible (jagi-budam-geum), requiring you to pay a designated portion of the bill yourself.
If every dollar spent were refunded with zero out-of-pocket cost, it would create moral hazardโincentivizing patients to overuse expensive, non-essential treatments simply because they are free. Excessive claims drain the insurance pool and inevitably drive up monthly premiums for all policyholders.
To keep the system sustainable, Korea has revamped Silson policies across multiple generations (from 1st to 4th generation). Newer policies set realistic copay percentages for non-covered items and increase premiums specifically for frequent high-volume claimants.
These deductibles and regular policy renewals act as essential safeguards, ensuring the insurance pool remains solvent and fair for everyone over the long term.
๐ค Common misconceptions
Buying multiple indemnity insurance policies will get you double or triple the reimbursement for the same hospital bill.
Indemnity insurance only compensates for the actual financial loss incurred. If you have multiple policies, the insurers split the payout proportionally (pro-rata indemnity). You will never receive more money than you actually paid out of pocket.
