I have a clearinghouse

Providers who use clearinghouses to process their claims need to enroll via EDI express enrollment in order to process claims and set up EFT/ERA.

To set–up Electronic Data Interchange (EDI), providers (or groups where applicable):

  • Must enroll for electronic claims submission
  • Must sign, and have on file, a Trading Partner Claims Agreement (“Agreement”) prior to submission of electronic claims
  • Must complete a self-registration process that includes an initial registration and the necessary request forms and business agreement(s)
  • Should sign up for EFT/ERA to ensure faster payment
