Modification of Existing Common Working File (CWF) Editing for Preventive Services

The purpose of this Change Request (CR) is to modify existing Common Working File (CWF) editing for preventive services. In some instances, when claims are paid outside the CWF, the beneficiary’s claim history is not updated in the CWF, leading to incorrect claim's history. To avoid this and make CWF information more accurate, this CR allows frequency limitation editing to be overridden by contractors. In addition, this CR updates IOM Pub.100-04, Chapter 4, Section 300.5.
