There are two types of grace periods:
high-impact grace period, and
The Office of Quality Review (OQR) determines which type of grace period to establish.:
We establish a high-impact grace period when we expect the new, clarified, or changed policy or procedure to affect a large workload. In a high-impact grace period, we remove all grace period cases from performance accuracy calculations.
We establish a low-impact grace period when we do not expect the new, clarified, or changed policy or procedure to affect a large workload. In a low-impact grace period, we include all grace period cases with a group I deficiency in calculating performance accuracy, but we count them as deficiency-free cases
1. High-impact grace period
When we expect a new, revised, or clarified policy or procedure to affect a large workload, e.g., when there has been a major revision to one of the widely applied listings, we exclude all grace period cases from performance accuracy statistics and do not report them in the normal QA process. Instead, we track grace period cases separately, and maintain separate data. We augment the initial QA sample to replace the grace period cases to maintain statistical precision in the reported accuracy rates.
For additional information on sample augmentation, see GN 04440.123D.4.
2. Low-impact grace period
When we do not expect a new, revised, or clarified policy or procedure to affect a large workload, we do not exclude grace period cases from adjudicating component performance accuracy statistics. However, we treat initial QA cases that fall under the grace period and contain a group I deficiency as deficiency-free cases for performance accuracy calculations. We apply the grace period only to initial QA cases.
For a detailed description of the two types of grace period and how they are applied, see GN
04440.123D and GN 04440.123E.
