Objectives This study aimed to investigate the status of Chuna manual therapy(CMT) usage before and after COVID-19 social distancing measures. Methods This study utilized Health Insurance data from April 2019 to May 2023. Quarterly data were collected for Simple Chuna (code 40710), Complex Chuna (code 40720;50% patient expense), Complex Chuna (code 40721;80% patient expense), and Special Chuna (code 40730). Results During the period covered by health insurance, the number of CMT patients was 8,315,838, with 19,332,786 instances of CMT, and a total cost of 544,651,407 won. Due to COVID-19, the application of CMT decreased in the first quarter of 2020, but recovered from 2021, showing an increase in usage by the first quarter of 2023. The decline in the use of all medical institutions in the fourth quarter is believed to be due to restrictions on health insurance coverage for CMT. Conclusions Further research on CMT health insurance is necessary. This research should inform discussions on policies aimed at expanding health insurance coverage for CMT.
