National Health Insurance Act Article 35
A grace period of fifteen days shall be allowed in case the group insurance applicants, the beneficiary, or the premium withholder do not pay the insurance premium during the period provided in this Act. If payment is not made by the end of the grace period, a belated surcharge of 0.1 percent of the amount payable shall be levied for each day of delay after the expiry day of the said grace period until the insurance premium is fully paid up with the maximum amounts as follows:1. 15 percent of the payment to be made by the group insurance applicant and premium withholder.2. 5 percent of the payment to be made by the beneficiary.The belated surcharge mentioned in the preceding paragraph may be waived if it is less than the amount to be fixed by the Competent Authority.If the insurance premium and the belated surcharge referred to in Paragraph 1 payable by the group insurance applicant/premium withholder remains unpaid for thirty days, the Insurer may refer the case to the court for administrative execution under the law; the same shall apply to the beneficiary [who has failed to pay either the insurance premium or the belated surcharge] for one hundred and fifty days.
