1. the evolution of the social role and compensation system of accidental death and dismemberment insurance

accidental medical insurance, also known as national insurance, is a system that covers the actual medical expenses incurred due to an individual's illness or injury. as of 2026, the system is moving beyond simple cost compensation to a data-driven compensation system combined with digital healthcare. in the past, insureds had to visit hospitals and remove paper documents and fax or app them back to the insurer, but the computerization of claims has completely changed the paradigm of claims.

throughout the history of accidental loss insurance, coverage and deductible percentages have been continuously adjusted, from the first generation of pretextual losses to the current fourth generation and the fifth generation under discussion. These generational differences highlight the importance of claim documentation, as the criteria for reviewing a claim varies depending on whether the item is a benefit or non-benefit.

2. legal basis for common required documents and tips for completing them

the most fundamental documents for filing a claim are the legal forms that confirm your identity and intent to file a claim. They are the basic building blocks that are common to any illness or accident.

the first is the claim form. this should detail the circumstances of the accident, the date of onset, and the medical treatment received. in recent years, this is increasingly being replaced by digital forms through insurer apps or integrated platforms, but if the information on the claim form doesn't match up with later medical certificates or medical records, it can cause delays in the review process.

the second is the privacy agreement. this is legally required for insurers to review your medical records and fact-check the hospital. the third is a copy of your ID. this is required to verify your identity, and additional proof of family relationship may be required for minors or proxy claims.

3. a breakdown of the evidence needed for ambulatory care claims

receipts and details of medical expenses are key to the most frequent ambulatory care claims. One mistake many members make is submitting card payment receipts, which cannot be used to support a claim.

receipts should follow the standard format set by the National Health Insurance Act, separating covered and uncovered items, including deductibles and co-payments, and breaking down uncovered items into elective and other uncovered charges.

a medical bill detail shows the specific tests, medications, and treatments you received. in 2026, non-paid injectables and hydrotherapy will be subject to more stringent scrutiny, so make sure the details are clearly labeled to demonstrate the need for the treatment.

4. understanding additional documentation requirements for hospitalization and surgery cases

because hospitalizations and surgeries have larger claims and higher coverage limits than office visits, insurers require more stringent documentation. a simple receipt is not enough; it must be accompanied by an official diagnosis from a doctor.

a medical certificate is the most authoritative documentation that a doctor has confirmed your condition and assigned a disease classification code. if you had surgery, you'll need an operative certificate or operative note, which should include the name and method of the operation and any unusual findings during the operation. A hospital discharge certificate proves the exact number of days you were hospitalized, which is the basis for the per diem compensation.

5. key tips for filing a claim and saving money

prescriptions filled at a pharmacy after a doctor's visit are also covered by Stop Loss Insurance. however, over-the-counter medications that are simply purchased at a pharmacy are excluded and must be filled by a doctor's prescription.

a useful tip here is to utilize prescriptions. typically, it costs between 10,000 and 20,000 won to get a medical certificate. however, if the hospital asks for a prescription for the patient to keep in addition to the one for the pharmacy, you can get it for free. this prescription contains the disease classification code and is an excellent substitute for an expensive medical certificate for small claims. Be sure to get a receipt from the pharmacy and submit an itemized bill, not a credit card receipt.

6. differentiated documentation standards and underwriting process for different claim amounts

the level of documentation required for stop-loss insurance varies depending on the size of the claim. this is for the convenience of the policyholder and risk management for the insurer.

in general, for small claims under KRW 100,000, a medical receipt, a detailed statement, and a prescription with the disease code are sufficient for most cases. however, if the amount exceeds KRW 100,000, a medical certificate or hospitalization certificate confirming the disease name is required. if the amount of the claim is more than KRW 1 million, the insurance company may strictly check whether the documents are original or not, or even conduct due diligence directly at the hospital.

7. future Prospects of the Loss24 System and Claims Computerization

as of 2026, the most significant change in insurance claims is the full implementation of computerized claims through the Silsom24 app. in the past, it was a routine to get paper documents at the hospital counter, but now the whole process is done with a smartphone.

silson24 is a system linked to the Insurance Development Institute and medical institutions, and when a subscriber selects their medical treatment details in the app and presses the send button, the hospital directly sends the data to the insurer. This not only saves the cost of issuing paper documents, but also eliminates the hassle of taking and uploading photos. For the elderly, the proxy claim function, which allows children to claim on behalf of their parents, has been strengthened, greatly increasing the utilization rate of insurance benefits for the digitally disadvantaged.

8. top causes of claim denials and strategies for dealing with them

sometimes, even if you've prepared the paperwork perfectly, your claim may not be paid. in 2026, the number of disputes is increasing, especially for non-payment items.

a typical example is hydrotherapy. repeated treatments for simple pain relief may be denied because the appropriateness of the treatment is questionable. this may require a physician's note or additional objective test results to show improvement in function. Nutritional injections or cataract surgery may also be denied without sufficient evidence of medical necessity. you should ask your insurer if the item is covered before undergoing treatment or carefully review the exclusions in your policy.

9. statute of limitations and how to manage stop-loss insurance claims

one of the things that many people miss is that insurance claims have an expiration date. according to commercial law and insurance policies, a claim must be exercised within three years of the date of the incident or it will lapse.

in the hustle and bustle of life, many people tend to collect receipts and try to claim them all at once, but after three years, they legally lose the right to seek compensation. however, contracts prior to December 31, 2014 had a two-year statute of limitations, which is now three years. in recent years, real-time claims have become easier to make thanks to systems such as Silson24, so it's a good idea to get in the habit of completing your claim on the same day you receive treatment or, at the latest, that weekend.

10. how the P&C market will change in 2026 and what you can do about it

the P&C market in 2026 is a complex time, with the stabilization of Generation 4, discussions of Generation 5, and government non-payment management policies. policyholders need to be interested in how their premiums are priced and allocated, not just in making claims.

in particular, since the fourth generation of insurance premiums are based on uncompensated utilization, reducing unnecessary uncompensated care will help reduce premiums in the long run. In addition, knowing which hospitals are connected to Silsom24 in advance can reduce the hassle of documentation. you can search for Silson24 participating hospitals on Naver or Kakao Maps apps.

11. frequently Asked Questions (FAQ)

Q1. Can I file a claim if I only have a card receipt?

yes, card receipts only show the total amount, so your insurance company cannot verify what treatment you received. You must obtain a medical bill or standardized receipt form from the hospital's secretariat.

Q2. Do I need a medical certificate for claims under KRW 100,000?

generally, you don't need a medical certificate for claims under KRW 100,000, just a receipt, a detailed statement, and a prescription with a disease code. however, depending on the insurance company or product, additional documents may be required, so please check.

Q3. Can I reimburse the cost of pharmacy medications under my accidental loss insurance?

yes, the cost of medications dispensed by a doctor's prescription is covered. however, each policy has a different deductible, so it is only worth filing a claim if your out-of-pocket expenses are greater than the deductible.

Q4. Does the Silson24 app work in all hospitals?

no, paperless billing is only available at healthcare organizations that have integrated with Silson24. your local doctor's office or pharmacy may not be participating yet, so check the list of participating hospitals in the app.

Q5. Can I file a claim now for treatment I received a long time ago?

you can file a claim now for medical treatment within three years of the date of the incident. if it's more than three years old, the statute of limitations has expired and it may be difficult to recover.

12. conclusion and future strategies for utilizing stop-loss insurance

preparing stop-loss claim paperwork is no longer a complicated task. In 2026, policyholders will need to have both paper-based knowledge and the ability to utilize digital platforms. you'll need a strategy that makes small claims easy with prescriptions and real-time app claims, while large claims and hospitalizations require meticulous documentation.

key takeaway: Receipts, details, and prescriptions are the basics for claims, and medical certificates are required for claims over 100,000 won. from 2026, make it a habit to file paperless claims with the Silson24 app.
