FISS DDE Access and Resources

The Fiscal Intermediary Standard System (FISS) is the standard Medicare Part A claims processing system. Providers can receive direct data entry (DDE) access to FISS in order to perform the following functions.

  • Enter, correct, adjust, or cancel your Medicare home health and hospice billing transactions
  • Access beneficiary eligibility
  • Check the status of a claim
  • Access various inquiry screens such as revenue codes, diagnosis codes, HCPCS codes, and reason codes.

Direct Access to FISS

To receive direct access to FISS, contact the CGS EDI (Electronic Data Interchange) department between 7:00 a.m. – 4:00 p.m. CT at 1-877-299-4500 (select Option 2) for assistance. You must also contract with a connectivity vendor to establish direct connection to the Enterprise Data Center (EDC) for FISS access through a connectivity product (e.g., IVANS). The CGS EDI department does not provide support for your connectivity product; therefore, you will need to contact your connectivity vendor for any issues related to your direct connection.
