Background: The 2018 revision of social insurance in Japan allows additional fees to be calculated for pediatric magnetic resonance imaging (MRI) that must be performed under sedation. The number and trend of actual claims since this revision was established is unknown. The aim of this study to investigate the use of the additional fees and any regional differences in the use. Methods: To analyze the claims of additional fees for pediatric sedated MRI after the fiscal year (FY) 2018, the actual claims in inpatient and outpatient practice was analyzed using publicly‐available data from the Ministry of Health, Labour and Welfare (MHLW). We analyzed the calculation rate for all MRI scans. Annual changes in the actual number and calculation rate were analyzed. The ratio of the number of additional fees to the overall number of pediatric radiological procedures was used to examine the geographic disparity. Results: The number of calculations from FY 2018 to FY 2020 was available. In FY 2020, only 1347 additional fees were calculated, corresponding to 0.35% of the total number of MRI scans. The number of fees showed a decreasing trend. Most cases were in the 0–4 year age group; however, there were a few cases in the 10–14 year age group without such a decrease. The relative number of calculations by prefecture showed an up to 14‐fold disparity. Conclusions: The requirements for sedation for pediatric MRI are strict, but they are not fully utilized. Measures such as relaxing the requirements for the fee are needed to make MRI‐related sedation safer.
