Error Files
9.5.3 – Error Files
(Rev. 921, Issued: 11-06-19 Effective: 11-04- 19, Implementation: 11-04-19)
The CMS established RAC workload limits for maximum number of claim adjustments
the RAC shall send to the MAC in a calendar month. It is assumed that the majority of
adjustments will be processed through the mass adjustment system. In some cases, claims
submitted through the mass adjustment system cannot be processed due to a submission
error and are identified on an error report. The RAC shall review the report, make the
necessary changes, and resubmit the claim. In these situations, the MAC shall not count
claims identified on error files, corrected and resubmitted by the RAC in the same month
against the monthly workload twice.
