The claims data of National Health Insurance (NHI) were used as the data source, and drugs with annual per-patient costsexceeding ten million KRW were defined as 'high-priced drugs.' The study selected the each year’s list of high-priceddrugs from 2010 to 2021 and analyzed the trends considering their spending size, manufacturer types, therapeutic groups,Risk-Sharing Agreements, and Economic Evaluation Exemption. The spending on high-priced drugs accounted for 8.0%of the NHI pharmaceutical expenditure in 2021, and it has been increasing annually by 14.3% since 2010. The expenditureon high-priced drugs introduced through the RSA (Risk-Sharing Agreement) rapidly increased, especially for oncologydrugs and immunosuppressants. This study defined high-priced drugs based on per-patient costs and observed the trendsin the expenditure of these drugs according to pharmaceutical characteristics. Based on this, it is significant in proposingissues and policy implications for noteworthy drug categories.
