Resource Based Relative Value Scale ( RBRVS)
• Medicare uses RBRVS 
• A system that sets a fee for procedures performed by a physician or other healthcare professional
• Covers procedures with a CPT code
• Based on estimates of costs of delivering services
• Introduced in 1992
• The two key components of each fee are the Conversion
Factor (CF) and the Relative Value Unit (RVU)
 The Conversion Factor
• Is the same for all CPT codes
• Is updated annually
• Converts RVUs to dollar fees
Relative Value Units
• Are determined for each CPT code
• Reflect the relative cost of providing a service
• Are not sensitive to inflation
• Are updated annually
• Incorporate factors to adjust for geographical differences
• Included a “Budget Neutrality Factor” prior to 2008
Medicare and WC Resource Allocation 
* RBRVS shifted reimbursement from specialty to primary care:
• For office visits, private payers reimburse about 110% of Medicare, similar to when RBRVS was introduced 
• For diagnostic testing, private fees are now about 135% of
Medicare, down from 220% in 1993
• Many WC fee schedules maintain high conversion factors for specialty care. Median WC fee schedules relative to Medicare are:
• 125% for office visits
• 180% for radiology
• 205% for surgery
