Objectives: This study aimed to examine the effect of indemnity private health insurance on the use of emergency medical services. Methods: Using the 2014–2018 Korea Health Panel data, the researchers applied propensity score matching based on Andersen’s model (1:1, caliper 0.2) to address endogeneity. The covariate balance was assessed using standardized mean differences, and both average treatment effect on the treated (ATT) and panel regression analyses were conducted. Results: The ATT analysis showed that individuals with indemnity private health insurance had significantly more non-urgent emergency department (ED) visits than uninsured individuals, and therefore significantly more ED visits in total, whereas no significant difference was observed in urgent visits. Panel regression results were consistent with these findings. Conclusions: Indemnity private health insurance was associated with increased non-urgent ED use, rather than with overall utilization, suggesting a potential moral hazard and the need for policy efforts to reduce non-urgent ED use.
