Electronic Data Interchange (EDI)

EDI is the process of using nationally established standards to exchange electronic information between business entities. While EDI is relevant to other Medicare business processes, this page provides information about electronic claim and eligibility transactions.

Why use EDI?

  • Eliminate paperwork
    Staff can accomplish more in less time, and you save money for postage and paper claim forms.

  • Flexibility
    Submit claims for multiple providers simultaneously and control claim frequency and volume.

  • Reduce claim errors
    Less manual entry, EDI edits that validate information reported on electronic claims, and electronic billing reports help ensure correct claim payment without the need to request claim reopenings, adjustments, or redeterminations (first level appeal).

  • Faster processing
    Medicare claims processing systems accept most electronic claims within 24 hours. In addition, the payment floor (i.e., waiting period for CGS to issue payment) is 13 days after the receipt date (electronic claims) vs. 26 days (paper claims).
