Facilities that are eligible for pay-for-performance under Regulation .14 of this chapter shall receive a score for each quality measure described in Regulation .15 of this chapter. For the quality measures described in Regulation .15B—E of this chapter, a facility is ranked and awarded points as follows: The highest ranked facility receives 100 percent of the points available; The median score, weighted by total days of care, receives 50 percent of the points available; Zero points would be received by any facility whose raw score is below the median by an amount equal to or greater than the difference between the highest score and the median score; and All other facilities will receive points proportionate to where the score falls within the range between the highest and zero. Points for each quality measure are summed.
