BackgroundAs a result of the Coronavirus disease 2019 (COVID-19) pandemic, health plans were required to implement, or voluntarily implemented, patient cost-share waivers for COVID-19-related emergency care. The impact of the cost waivers on patients for emergency physician services has not been previously reported. ObjectiveTo measure the impact of COVID-19 cost-sharing waivers on patients for emergency physician services. MethodsA multicenter retrospective review of emergency physician commercial claims was conducted to determine the impact of the patient cost share waivers on COVID-19-related emergency physician services. Seventy-seven emergency departments (EDs) representing about a quarter of all EDs in California were included in the study. Emergency physician claims during a 9-month prepandemic period in 2019 were compared with claims during a 9-month pandemic period in 2020 to determine if there were any changes in the patient cost share between the two study periods and between COVID vs. non-COVID-related care. ResultsThe average patient cost share was $19 for COVID-19-related emergency physician professional care and $52 for visits unrelated to COVID-19. Compared with non-COVID-19 care visits, the patient cost share was 63% less for COVID-19-related care. There was a small increase (< $2) in the patient cost share for non-COVID-19 emergency professional care during the pandemic compared with the prepandemic period. ConclusionPayment policies implemented by California health plans were effective at reducing the patient cost share for patients that required COVID-19-related emergency physician care.
