This section provides an overview of Electronic Data Interchange (EDI) and retiree processing.
Electronic Data Interchange (EDI) is the electronic transmission of data between computer systems.
All participants in the RDS Program must use EDI to exchange retiree files with CMS' RDS Center throughout the Application Lifecycle.
Information is exchanged using a Comma Separated Value (CSV) file or Mainframe file where each line represents one beneficiary, Benefit Option, and Subsidy Period.
Examples of EDI include:
Pharmacy Prescriptions: Data is exchanged between the Pharmacy and the Pharmacy Benefit Manager (PBM) at the point of sale when a prescription is presented. The patient's eligibility and cost information is verified and sent back to the Pharmacy.
Auto Loans: When applying for an automobile loan, several dealerships electronically request an applicant's credit history from a credit bureau. The information is electronically communicated to the dealership's computer for analysis and scoring without human intervention.
Merchants and Suppliers: EDI is utilized between merchants and suppliers to electronically communicate purchase orders, shipping invoices, shipping notices, etc.
The Plan Sponsor provides demographic and benefit enrollment information about the beneficiaries for whom it is seeking subsidy. CMS' RDS Center evaluates program eligibility and provides the Plan Sponsor with approved Subsidy Periods for each Qualifying Covered Retiree (QCR).
The main components of retiree processing include:
