NCQA inverts rates and percentiles where a “lower value represents better performance” to a “higher value represents better performance” scale in the Health Plan Ratings scoresheets, and then truncates the inverted rate to 3 decimals. For example, a raw rate of 0.0147738807 would display as .985 (1 – 0.0147738807 = 0.9852261193, truncated to 3 decimals).
