RBRVS

The Resource-Based Relative Value Scale is the methodology Medicare uses to calculate physician payment rates based on the resources required to provide each service.

The Resource-Based Relative Value Scale is the backbone of how Medicare and most commercial payers determine how much to pay you. Understanding RBRVS helps you understand why some services pay more than others and why your reimbursement varies by location. Every CPT code is assigned a relative value unit (RVU) that has three components. The work RVU reflects the physician's time, skill, training, and intensity required for the service. The practice expense RVU covers overhead costs like rent, staff salaries, equipment, and supplies. The malpractice RVU covers the cost of malpractice insurance for that service. The total RVU is the sum of these three components, adjusted by the Geographic Practice Cost Index (GPCI) for your location. A provider in Manhattan has a higher GPCI than a provider in rural Mississippi because the cost of doing business is higher. The location-adjusted RVU is then multiplied by the conversion factor, which is a dollar amount set by Congress each year, to arrive at the Medicare allowed amount. The formula is: Payment = [(Work RVU × Work GPCI) + (PE RVU × PE GPCI) + (MP RVU × MP GPCI)] × Conversion Factor. Why does this matter for credentialing? Because when commercial payers tell you they pay "120% of Medicare," they mean they take the RBRVS-calculated Medicare rate and multiply it by 1.2. If you understand RBRVS, you can calculate exactly what a payer should be paying you for any specific service and verify that your payments match your contract. RVUs are updated annually by CMS. The AMA's RVS Update Committee (RUC) reviews codes and recommends RVU values, and CMS makes the final determination. Changes in RVU values directly affect your reimbursement, so pay attention to the annual Medicare Physician Fee Schedule Final Rule published each November.
