The Outstanding Claims Report can be run to get a list of claims that have not been paid. You will run the report twice. Once for CMS-1500 (paper) claims and once for DiskImage 02/12 (electronic) claims.
Before running the report, you need to determine what range of claims you want to view, based on the number of Days Open. Not the dates of service. For example: over 30 days open; 30 to 90 days open etc.
Once you know the criteria for the range of days open you are ready to run the report.
