Your 837 4010 EMC Pre-Pass Report
The electronic media claims (EMC) system reviews every claim for a number of pre-pass edits to ensure that claim data is valid. It is very important that you review this report to ensure that your claims are being accepted into the Medicare processing system.
Currently there are a number of edits set to informational regarding the National Provider Identifier (NPI). If you are sending NPIs along with your Medicare legacy numbers, the EMC system will verify that they are on the NPI crosswalk file. If a match is not found on the crosswalk file, an informational edit will set on your report. The edits are M340 through M351.
The first step in alleviating the error is to go to the NPI enumerator and add any of your current legacy ID numbers, Medicare PIN, UPIN, etc. The NPI enumerator Website is:
