Relative Value Scales

**Definition:** Coded listings of physician or other professional services using units that indicate the relative value of the various services they perform. They take into account time, skill, and overhead cost required for each service, but generally do not consider the relative cost-effectiveness. Appropriate conversion factors can be used to translate the abstract units of the relative value scales into dollar fees for each service based on work expended, practice costs, and training costs.
