Refunds can be claimed through the NHIS website or mobile app
The National Health Insurance Service announced Wednesday that it operates a copayment refund system to return overpaid medical fees to patients.
The refunds apply when the Health Insurance Review and Assessment Service reviews fees charged by hospitals, pharmacies or other medical institutions and finds that the copayment collected exceeded the standard amount.
The NHIS sends eligible patients a monthly notice detailing their refund amount along with a payment request form, delivered by electronic document or postal mail.
Eligible patients can apply for a refund through the NHIS website (under Customer Service > Find a Service > Copayment Refund Inquiry/Application), the mobile app (under All Menus > National Health Insurance > Refunds > Refund/Support Inquiry and Application), or by mail, in-person at a branch office, or by calling the customer center.
Refunds are paid the day after the application and branch review are completed. Applicants must submit their request within three years of the date the initial notice was sent.
An NHIS official urged the public to exercise caution, noting that the service never sends refund application notices containing URLs via text message. Anyone who receives a suspicious text from an unidentified sender should delete it immediately, the official said.
