 (d)(1) Except for anesthesia services, to determine the maximum allowable reimbursement for a physician service rendered on or after July 1, 2004 the following formula is utilized: RVU y conversion factor y 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.   

 (2) To determine the maximum allowable reimbursement for anesthesia services ( CPT Codes 00100 through 01999) rendered after January 1, 2004, the following formula is utilized: (basic value + modifying units (if any) + time value) y (conversion factor y .95) = maximum reasonable fee.   

 (e) The following procedures in the Pathology and Laboratory section (both professional and technical component) will be reimbursed under this section: CPT Codes 80500, 80502; 85060 through 85102; 86077 through 86079; 87164; and 88000 through 88399.
