Have you ever looked at a receipt after a hospital visit and wondered, 'How much of this cost can I get back?' Indemnity health insurance, also known as actual medical expense insurance, is the most popular type of insurance that covers a significant portion of medical expenses incurred from unexpected illnesses or injuries we face in life. However, many people simply sign up for it without knowing how to use it properly when needed, or conversely, mistakenly believe that they can get all their expenses reimbursed unconditionally.
Indemnity health insurance is based on the principle of covering 'the medical expenses I actually paid.' In other words, it is structured to pay out insurance benefits after deducting a certain percentage from the amount you paid, including non-covered items that are not covered by the National Health Insurance. Today, we will start with these basic concepts and carefully examine the claim procedures to minimize mistakes.
The first step to understanding indemnity health insurance is to become familiar with the terms 'covered' (geubyeo) and 'non-covered' (bi-geubyeo). Covered items are those where the National Health Insurance applies, and the state bears a portion of the cost, while non-covered items are those where health insurance does not apply, and the patient must bear the full cost. Indemnity insurance covers both, but since the coverage scope and limits vary by product, you must carefully review the terms and conditions when signing up. In particular, the deductible ratio and coverage details vary significantly depending on when you signed up (e.g., before 2009, before 2017), so checking which 'generation' of indemnity insurance you have is the priority. Indemnity insurance policies have been reformed over time, and depending on the time of enrollment, the deductible range varies from 0% to 30%. Checking your insurance policy document to identify the exact generation is the fastest way to understand your coverage scope.
Checklist to Confirm Before Signing Up for Indemnity Insurance

Insurance is a financial product that you must maintain for a long time once you sign up. Therefore, rather than signing up blindly, it is important to consider whether it fits your current health status and economic situation. Below are the essential items to check before signing up.
- Coverage Scope: Are the hospital treatments I frequently use covered? Specifically, check if special riders such as manual therapy or MRI are included.
- Deductible Ratio: What is the minimum amount I have to pay? Generally, a deductible of 10-20% for covered items and 20-30% for non-covered items occurs.
- Renewal Cycle: What is the cycle for insurance premium increases? Most are 1-year renewal types, with re-enrollment cycles returning every 5 or 15 years.
- Payment Limit: Is the maximum amount I can receive per year or per illness sufficient? You must check the limits for outpatient treatment and inpatient treatment separately.
In particular, for renewal-type products, there is a high possibility that premiums will increase as you get older. Even if it looks cheap now, you must consider your ability to pay 10 or 20 years from now. Also, if you have existing insurance, it is worth checking if you are wasting premiums due to overlapping coverage. Since indemnity insurance only provides proportional compensation within the scope of actual medical expenses incurred even if you have multiple policies, overlapping coverage is an unnecessary economic expense. If you have insurance you signed up for in the past, you should comprehensively evaluate the coverage scope and premiums by comparing it with the standardized indemnity insurance currently on the market. The perception that older insurance is unconditionally better is wrong, and you should decide whether to maintain it by comparing the deductible and coverage limits with your health status.
Indemnity Claims: Where Should I Start?

When you actually receive treatment and claim insurance benefits, several documents are required. The necessary documents vary depending on the size of the hospital and the details of the treatment, so checking in advance can prevent cumbersome return visits. Basic requirements include medical expense receipts and detailed statements of medical expenses. If the amount is large or a diagnosis name is required, a medical certificate or prescription may be additionally requested. Especially for outpatient treatment, a medical receipt alone is often insufficient, so it is important to get into the habit of requesting 'documents for insurance claims' from the start.
Many people think the claim process is complicated, but recently, it is possible to make claims easily by taking pictures of receipts with a smartphone through the insurance company's app. For more specific preparation methods regarding indemnity insurance claim documents, please refer to Indemnity Claim Documents: Essential Items Easily Missed and Efficient Preparation Methods. When claiming, you must include a detailed statement of medical expenses to ensure accurate compensation for non-covered items, and don't forget to keep your medicine bag or pharmacy receipt if pharmaceutical costs were incurred. When requesting documents from the hospital administration office, it is best to specify that they are for 'submission to an insurance company' and confirm the list of required documents. Recently, systems are well-equipped to print supporting documents even when using unmanned payment kiosks.
Common Indemnity Claim Mistakes and Preventive Measures

Common mistakes in the insurance claim process include 'missing documents' and 'exceeding the claim deadline.' When receiving documents from the hospital, clearly state that they are for submission to an insurance company and check if all necessary items are included. In particular, for non-covered items, if there is no detailed statement, the compensation may be rejected or considered only as covered items, reducing the compensation amount. To verify if an item is eligible for compensation, you must check if 'non-covered' items are clearly listed by code on the hospital's detailed statement of medical expenses.
Also, the claim period for insurance benefits is generally 3 years from the date of the accident. If you claim too late, it may be difficult to find data and prove the claim, so it is recommended to get into the habit of claiming as soon as possible after treatment. The following are final checklist items before claiming:
- Are the date and hospital seal properly stamped on the receipt?
- Are non-covered items clearly marked on the detailed statement?
- Did you also keep the pharmacy receipt (medicine bag, etc.)?
- Is the disease classification code accurately recorded when issuing a medical certificate?
As a tip for preventing mistakes, if you request 'documents for indemnity insurance claims' at the hospital administration office, they often prepare a set of necessary documents. Also, for small claims under 100,000 KRW, it is convenient to proceed via the app, and for large claims, it is recommended to make copies of relevant documents in advance as medical consultation may be required during the review process. Additionally, when claiming insurance benefits, you must ensure that your own account number is entered correctly, and when claiming on behalf of a family member, a power of attorney or family relation certificate may be required. Checking the documents required for your case through the insurance company's customer center before claiming is the best preventive measure to reduce unnecessary hassle.

Also, non-covered treatments such as manual therapy or extracorporeal shockwave therapy are seeing stricter reviews by insurance companies recently. If you are in an environment where you frequently receive such treatments, you should check the coverage limits and payment conditions for those items more carefully.

Since the convenience of mobile claim systems varies by insurance company, if you are not familiar with using apps, prioritizing companies with active customer centers is also a good strategy. As insurance premiums are costs paid monthly, you should approach it from a long-term perspective, fully considering your economic conditions and future renewal possibilities.
In Conclusion: Indemnity Insurance is a Safety Net for a Healthy Economic Life
Indemnity insurance is not a means to provide unconditional benefits, but a safety net that protects your assets from unexpected medical expenses. To be guaranteed coverage when needed without wasting premiums, you need to make an effort to read the terms and conditions yourself and become familiar with the claim procedures. Based on the checklist covered today, check your current insurance status once again. Accurate information leads to economic freedom. Since you cannot sign up for insurance after you get sick later, preparing and maintaining it in advance while you are healthy is the wisest form of financial management and the beginning of risk management. If you have the habit of regularly checking your coverage details once a year, you will be able to receive solid protection without panic when the moment of need arises.
