Reduction Rate




Payment amounts for services provided prior to April 1, 2001













Revised payment amounts for services provided on or after April 1, 2001









Calculation of Threshold Reduction

The method of calculation is unaffected except that each threshold level has increased by $10,000. The reductions are calculated at the percentages above as physicians reach the level of payments noted. However, to reach those payment amounts, the actual billings are higher since payments are reduced once the threshold is reached. The calculations take these reduction amounts into account prior to determining the level and percentage deduction to apply. The new total billing amounts that correspond to each revised payment level above are shown below.
