How does medical-expense insurance work in Korea?

Medical-expense insurance calculates a benefit from the medical costs that the insured person actually paid for inpatient or outpatient treatment and that are covered under the policy terms. Its calculation differs from fixed-benefit insurance, which pays an agreed amount when a specified diagnosis, operation or hospital stay occurs.

Paying a hospital bill does not mean that the entire amount is covered. The insurer determines the benefit after applying factors such as National Health Insurance treatment, the distinction between benefit and non-benefit items, items excluded under the policy, out-of-pocket amounts, and per-claim or annual limits. Costs that are not treatment costs, such as a fee for issuing a medical certificate, may also be excluded.

Holding several medical-expense policies does not mean that you receive the full amount several times and profit beyond the loss actually incurred. If there are multiple contracts, each may pay a proportional share under its terms. Duplicate medical-expense coverage may therefore increase premiums while total payment remains limited, so check your existing contracts first.

Policies called “medical-expense insurance” can have substantially different coverage, out-of-pocket amounts, renewal and re-enrollment rules, and non-benefit endorsements depending on their purchase date and generation. The terms of the current product generation must not be presented as if they also applied to older first- through fourth-generation contracts. When considering a change to an existing contract, compare more than the premium: check any reduction in coverage, increase in out-of-pocket costs and the conditions for reversing a conversion.

The basic claim method is to submit receipts and required medical documents to the insurer. Connected medical providers can send some documents through 실손24, but not every provider is connected.

Current system example

The Financial Services Commission announced fifth-generation medical-expense insurance with a structure focused more strongly on essential and serious treatment and different out-of-pocket amounts and limits for certain less serious non-benefit treatment. Existing policyholders may have a different generation of contract, so they must not apply the current new-product terms to their own policy without checking.

Product generations and terms can change. Before publication or making a decision, confirm the generation currently sold and the terms of your own contract.
