A claim may be failed by Apex if it is missing a required Submitter ID. The Submitter ID is assigned by the payer when completing EDI enrollment. If your claim fails due to a missing Submitter ID after you have completed EDI enrollment, you will need to locate your Submitter ID and contact the Apex enrollment team. If you completed your EDI enrollment through EDISS, your can easily retrieve your Submitter ID from the EDISS Connect website.
NOTE: Submitter IDs are required for any Medicare within the Noridian Jurisdiction, such as California.
