Within each State sample, the average changes were approximately budget neutral in that the average rate change for all facilities (not weighted by Medicaid patient days) was approximately zero.
2
Low case-mix and high case-mix facility groups were derived for each State based on whether the facility was below or above the median case-mix index (average-rate ratio) for the State sample.
