(b) The above cost center uses as the basis for the Standard Unit of Measure the applicable procedures from the Neuro-Muscular section of the Medicine Relative Values as determined by the California Medical Association, 1974 California Relative Value Studies (RVS). Relative Value Units for unlisted, BR (By Report), and RNE (Relativity Not Established) procedures are to be reasonably estimated by qualified personnel. Because the California Medical Association is no longer publishing their Relative Value Studies booklet, the applicable procedures from the Neuro-Muscular section of the Medicine chapter are set forth below with the approval of CMA.
