Descriptor of AMA CPT/RUC Process

The American Medical Association (AMA) is responsible for the development and maintenance of the CPT® code set. CPT codes are used on insurance claims to report the services and procedures performed by physicians and other healthcare providers. The use of CPT codes provides a uniform means by which all stakeholders in healthcare are able to communicate to about the services provided to patients. The AMA is also responsible for the valuation of CPT codes. The AMA Relative Value Update Committee (RUC) develops relative values units for CPT codes. The relative values are used to determine a payment amount for healthcare services and procedures. The AMA RUC also provides those RVUs to the Centers for Medicare & Medicaid Services (CMS) which CMS may then use to set payment amounts for CPT codes when paid under the Medicare Physician Fee Schedule.
