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).
The Specialty Society Relative Value Scale Update Committee or Relative Value Update Committee (RUC, pronounced "ruck") [1] is a volunteer group of 31 physicians who have made highly influential recommendations on how to value a physician's work when computing health care prices in the United States' public health insurance program Medicare.
Before RVUs were used, Medicare paid for physician services using "usual, customary and reasonable" rate-setting which led to payment variability. [2]The Omnibus Budget Reconciliation Act of 1989 enacted a Medicare fee schedule, and as of 2010 about 7,000 distinct physician services were listed. [2]
Prior to the MMA, the MVPS was in use instead of the SGR. The Medicare, Medicaid, and SCHIP Balanced Budget Refinement Act of 1999 (BBRA) changed the calculation from fiscal year (FY) to calendar year (CY). The table on the right is a list of the actual yearly MEI and physician fee update conversion factor.
Risk-weighted asset (also referred to as RWA) is a bank's assets or off-balance-sheet exposures, weighted according to risk. [1] This sort of asset calculation is used in determining the capital requirement or Capital Adequacy Ratio (CAR) for a financial institution.
The use of relative value is a method of determining an asset's value that takes into account the value of similar assets. In contrast, absolute value looks only at an asset's intrinsic value and does not compare it to other assets.
The loss random variable is the starting point in the determination of any type of actuarial reserve calculation. Define K ( x ) {\displaystyle K(x)} to be the future state lifetime random variable of a person aged x.
The group exposed to treatment (left) has the risk of an adverse outcome (black) reduced by 50% (RRR = 0.5) compared to the unexposed group (right).
