Difference and total values are reported to the nearest integer.
a2018 JHIFS labour costs on the day of procedure were adjusted using a multiplication factor of 0.7 to account for the overestimation of these costs when using the JHIFS tariff compared to FFS tariffs.
Abbreviations: DBS: deep brain stimulation; JPY: Japanese Yen; MRgFUS: magnetic resonance-guided focussed ultrasound; RFT: radiofrequency thalamotomy.
