Abstract：
:The Resource-Based Relative Value Scale (RBRVS) has been the defining algorithm for professional reimbursement of medical services since its introduction in 1992. This article reviews the history of the RBRVS, with an emphasis on the integral involvement of the radiology and neuroradiology communities. Appropriate reimbursement of radiology procedures has been chaperoned by physician volunteers and society staff attending Current Procedural Terminology Panel meetings and American Medical Association/Specialty Society RVS Update Committee (RUC) meetings. In recent years, governmental and RUC initiatives have created an unfavorable environment for neuroradiologists to maintain reimbursement levels seen previously.
