Resource-based relative value scale
（重定向自RBRVS）
Resource-based relative value scale (RBRVS) is a schema used to determine how much money medical providers should be paid. It is partially used by Medicare in the United States and by nearly all health maintenance organizations (HMOs).
RBRVS assigns procedures performed by a physician or other medical provider a relative value which is adjusted by geographic region (so a procedure performed in Manhattan is worth more than a procedure performed in Dallas). This value is then multiplied by a fixed conversion factor, which changes annually, to determine the amount of payment.
