Electronic Data Interchange (EDI) is the computer-to-computer electronic exchange of business documents using standard formats. One method of EDI is the ability for suppliers to transmit Electronic Media Claims (EMC) to Medicare.

The Common Electronic Data Interchange (CEDI) contractor, National Government Services, provides a single electronic front end solution for all DME MAC suppliers. CEDI works closely with DME MAC software vendors, billing services, clearinghouses and trading partners (electronic submitters) on all electronic front -end needs.

The following electronic transactions are handled by CEDI:

• Electronic claims [American National Standards Institute (ANSI) X12N 837 and National Council for Prescription Drug Programs (NCPDP)]
• Delivery of all electronic front-end acknowledgements and reports
• Electronic Remittance Advices (ERA)
• 276/277 Claim Status Request/Response

It is imperative for suppliers to receive and work the front-end acknowledgement reports to ensure all claims are received within the Noridian claims processing system, including any CMN/DIF transmitted with the claim. When these reports are not worked, Noridian never receives the claim into the claims processing system until the claim and/or CMN/DIF is corrected and resolved.
