(1) The OMFS 2003's “General Information and Instructions” section is not applicable. The “General Information and Instructions, Effective for Dates of Service on or after July 1, 2004,” are incorporated by reference and will be made available on the Division of Workers' Compensation Internet site http://www.dir.ca.gov/DWC/OMFS9904.htm or upon request to the Administrative Director at:

(d)(1) Except as specified in this section, or otherwise provided in this Article, except for anesthesia services, to determine the maximum allowable reimbursement for a physician service rendered on or after July 1, 2004, but before January 1, 2014, the following formula is utilized: RVU x conversion factor x percentage reduction calculation = maximum reasonable fee before application of ground rules. Applicable ground rules set forth in the OMFS 2003 and the “General Information and Instructions, Effective for Dates of Service on or after July 1, 2004,” are then applied to calculate the maximum reasonable fee.
(c)(1) Table A, “OMFS Physician Services Fees for Services Rendered on or after July 1, 2004,” which sets forth each individual procedure code with its corresponding relative value, conversion factor, percentage reduction calculation (between 0 and 5.0%), and maximum reimbursable fee, is incorporated by reference.
