What is the purpose of a probe sample for a CIA?
Answer 8: The objective of conducting a probe sample for providers under a CIA or Agreement is to establish an estimate of the variability of the overpayment amount in the population from which the sample was drawn. The results of the probe sample allow the reviewer to estimate how many sample units are needed for the results of the full sample to meet certain confidence and precision levels (e.g., generally 90% confidence and 25% precision level).
