Historically, Medicare has operated under the assumption that providers respond to reductions in reimbursement through increased provision of services in an effort to offset declining practice revenue; however, some recent empirical work examining fee reductions has found evidence of either small offsetting effects or reductions in the quantity supplied. Using a distance matching approach that matches practices to nearby practices that are subject to different reimbursement rates, we find overall evidence in support of Medicare's offsetting assumption collectively for all services and for evaluation and management services. We also find evidence consistent with a traditional volume response for imaging and testing services.
从历史上看，医疗保险计划假设提供者通过增加服务的提供来应对报销的减少，以弥补不断下降的执业收入；然而，一些最近研究费用削减的实证研究发现，要么是抵消效应很小，要么是供应数量减少。通过使用距离匹配方法将实践与受不同报销率影响的附近实践进行匹配，我们总体上发现了支持医疗保险计划的抵消假设的证据，这些证据适用于所有服务以及评估和管理服务。我们还发现了与成像和测试服务的传统数量反应一致的证据。
