National Health Insurance refunds can be checked and applied for through the National Health Insurance Service (NHIS) website after identity verification. The procedures and precautions are summarized below.

Log in via Simple Authentication, Joint, or Financial Certificates

On the NHIS website, login menus are divided into individual members and workplace members; general subscribers should select 'Individual Member Login.' Available login methods include simple authentication and joint or financial certificates.

Simple authentication uses authentication means provided by private electronic signature operators such as Naver, Kakao, and financial institutions to verify identity. When using joint or financial certificates, certificates issued by financial institutions such as banks or official certification agencies can be used. However, some certificates may require prior registration on the NHIS website, so users should check the guidance provided.

Check Eligibility Through the 'Refund Inquiry and Application' Menu

After logging in, eligibility for payment can be checked through the 'Refund Inquiry and Application' menu on the NHIS website. If a refundable amount is found, users can check the refund type and expected payment amount, then proceed with the application. For actual payment, personal bank account information must be entered in principle.

Refund Types Vary by Subscriber

Health insurance refunds may include premium refunds arising from duplicate or mistaken payments, as well as amounts returned when out-of-pocket medical expenses exceed certain thresholds, among other types. Eligibility and amounts vary depending on each subscriber's circumstances.

In particular, the out-of-pocket maximum system is a scheme in which the NHIS covers the portion of health-insured medical costs paid by a subscriber over a certain period that exceeds the individual cap. The cap may differ based on income level and subscriber circumstances, so checking refund eligibility directly through the NHIS inquiry results is the most accurate approach.

Beware of Requests for Personal Information: Check Directly on the NHIS Website

The NHIS website login page also offers optional installation of PC firewall and keyboard security programs. If errors occur during login, users can consult the certificate guidance or system error helper.

The NHIS advises users to stop the authentication process if another person requests identity verification, warning that personal information could be misused. Caution is also needed during refund applications against cases where personal information or authentication numbers are requested via text messages or phone calls.
