In early 1986 a national study of resource-based relative value scales (RBRVSs) for physician services was undertaken by Hsiao and colleagues at the Department of Health Policy and Management, Harvard School of Public Health, Boston, Mass, with the cooperation and support of the American Medical Association, Chicago Ill; the study was financed by the Health Care Finance Administration, Washington, DC. It was stated that: "The purpose of this study is to develop resource based relative value scales (RBRVS) for surgical and medical services. The RBRVS will be developed based on scientific methods with objective data."
Eighteen specialty societies and several medical subspecialties provided panels of medical experts for this study. These technical panels were requested by Hsiao: to assist in four essential functions:
Reviewing and commenting on the scope and method of this study;
Advising on the selection of the medical and surgical procedures to be studied;
Critiquing and refining
