How many units must be reviewed as part of a Full Sample under a CIA Claims Review?
There is no set number of units that the reviewer is required to examine in the Full Sample. The Full Sample size is based on the mean and standard deviation of the overpayment amount as calculated in the Probe or Discovery Sample. As a result, the Full Sample must include a sufficient number of sampling units to yield results that estimate the overpayment in the population to be within certain confidence and precision levels (e.g., 90% confidence and 25% precision). The sample size will vary according to the variability of the Probe or Discovery Sample and the size of the population.
