Diffusion of Medicare's RBRVS and related physician payment policies.

In 1992, Medicare reformed its physician payment method by implementing the Medicare fee schedule (MFS), of which the resource-based relative value scale (RBRVS) is a major component. Using a recent survey and case studies, we examine the diffusion of Medicare's RBRVS to non-Medicare payers and how those payers use and perceive the RBRVS and MFS policies. We find that approximately one-third of payers that participated in the survey have adopted RBRVS-based payment systems in varying degrees while another 40 percent were seriously considering its adoption. Prospects for expanded use of Medicare's RBRVS appear favorable.
