Electronic Billing and EDI Transactions

Electronic data interchange (EDI) is the automated transfer of data in a specific format following specific data content rules between a health care provider and Medicaid, or between Medicaid and another health care plan.

  • For billing, EDI speeds payment and eliminates costs associated with paper claims.
  • You can submit electronic claims through a clearinghouse or through your existing, HIPAA-compliant business management software.

This information is for health care providers, clearinghouses and billing services that submit transactions to or receive transactions from Medicaid.

Testing Requirement and Instructions

To use EDI, a provider or clearinghouse must first test transmissions on the Maryland Medicaid Electronic Exchange (MMEE).
