Welcome to
National Government Services CEDI

The CEDI (Common Electronic Data Interchange) provides a single, electronic front end solution for all Medicare DME suppliers. CEDI works closely with software vendors, billing services, clearinghouses, and Trading Partners (submitters) for their Medicare DME electronic transactions.

All DME MAC electronic claims (X12 837P and NCPDP D.0) as well as X12 276 transactions are collected by CEDI. CEDI also returns all DME MAC electronic front end acknowledgements/reports, X12 835 electronic remittance advices and X12 277 claim status response transactions.

NOTE: CEDI does not handle Claim Status Inquiry (CSI) or Electronic Funds Transfer (EFT). DME MAC suppliers must contact the appropriate DME MAC Jurisdiction for CSI and EFT information.
