Public interest is growing in the 'copayment refund' system, through which the National Health Insurance Service (NHIS) returns to subscribers the amounts over-collected beyond the legal standards by medical institutions such as hospitals, clinics, and pharmacies.

What is a Copayment Refund? It is a system in which, when a medical institution is found to have collected treatment fees in excess of the statutory standards, the NHIS deducts or collects the excess amount from the treatment fees payable to the institution and returns it to the person who actually received the treatment.

How to Check and Apply Those eligible for refunds are individuals who received treatment at medical institutions. In principle, applicants must apply in person; however, in unavoidable circumstances, a workplace subscriber or family member may apply on their behalf. If you paid more than the standard copayment after using a hospital, clinic, or pharmacy, you should first check whether a refund has been generated through the NHIS official online service.

If a refund has been generated, follow the instructions to complete identity verification and the application process. By accurately entering required information such as your payment account details, you can receive the refund.

• *Personal Information Collection and Precautions**
• To receive a refund, you must consent to the collection and use of personal and unique identification information during the application process.
• Items collected: Personal information such as name, workplace name, mobile phone number, and bank account number, as well as unique identification information such as resident registration number and business registration number
• Purpose of collection: Payment of refunds for health insurance, long-term care insurance, and pension insurance premiums
• Retention and use period: Semi-permanent

You may choose not to consent to the collection of personal information; however, please note that this may limit the payment of your refund, so you must review the relevant details before applying.

Use of Official Channels is Essential Copayment refunds are not automatically generated for everyone simply because they paid treatment fees. Whether you are actually eligible for a refund and the refund amount vary depending on your individual treatment history and verification results.

In particular, since the refund application requires the entry of financial information such as bank account numbers, you should never use text messages or internet advertisement links from unknown sources. It is most accurate and safe to check under your own name through official NHIS channels and apply following the prescribed procedures.
