The number of claims and patients steadily rose over the years from 7430 claims for 3989 patients in 2010 to 11,523 claims for 6226 patients in 2018. The predominant age group was 15 to 24 years. Regarding the frequency of service categories for PD in the claims, consultation was the most common and costly service category in WM (72,120 cases, 47.89%; 631,912 USD, 69.74%), while injection and analogous treatments was the most common and costly service category in KM (97,157 cases, 72.41%; 314,696 USD, 55.86%). Regarding the drug prescriptions, nonsteroidal anti-inflammatory drugs (NSAIDs) (26,617 cases, 40.47%) were the most frequently prescribed drug for PD in pharmacies and hospitals.Conclusion: The result shows an annual increase in healthcare utilization for PD with the fastest rate in individuals aged 15 to 24 years. This study provides data on the current utilization of WM and KM care for PD for policymakers. Furthermore, we analyzed the frequency and cost of common treatment modalities in WM and KM, which would be useful data for clinicians and researchers.Keywords: primary dysmenorrhea, healthcare administrative claims, health care costs, medical use
