The DDE Online Remote Terminal Access was designed as an integral part of the Fiscal Intermediary Standard System (FISS) to give Medicare providers a direct access mechanism for answering questions about their claims. DDE users may perform the following functions electronically:

  • Submit UB-04 claims
  • Correct, adjust, and cancel claims
  • Perform inquiries such as beneficiary eligibility, claims history, revenue codes, diagnosis codes, etc.
  • View certain online reports

The DDE User's Guide has been separated into six sections. Please refer to the following sections for detailed information about using the DDE screens.
