Electronic Data Interchange (EDI) Transactions

The fastest way to conduct business with BCBSIL throughout the entire claims process is via Electronic Data Interchange (EDI)—the computer-to-computer transmission of standardized information. EDI transactions are often identified by numbers assigned by the American National Standards Institute (ANSI). Here are some examples:

  • Eligibility & benefits inquiry/response (ANSI 270/271)
  • Referrals, pre-certification and authorizations (ANSI 278)
  • Electronic claim submission (also known as Electronic Media Claims, or EMC) [ANSI 837P (Professional) or ANSI 837I (Institutional)]
  • Claim status request/response (ANSI 276/277)
  • Claim payment via Electronic Funds Transfer (EFT)
  • Electronic Remittance Advice (ERA), or delivery of claims payment information (also known as ANSI 835)

Online Transaction Schedule

Effective Jan. 1, 2013, online Eligibility & Benefits (270/271) and Claims Status (276/277) transactions may be conducted almost continuously, with the exception of Sunday, 8 p.m. to midnight, CT.*


*Non-routine downtime will be communicated via designated third party independent vendor websites at least one week in advance.

  1. Establish a vendor connection. Some electronic transactions, such as EFT, may be set up directly with BCBSIL. For other EDI transactions, you will need to enlist the services of a third-party electronic business vendor. See the E-Commerce Connections menu below for more details.
  2. Follow standards and guidelines. When conducting EDI transactions, health care providers, billing agents and clearinghouses must follow Health Insurance Portability and Accountability Act (HIPAA) standards. Visit our HIPAA Regulations and Implementation Guidelines page for more details.

How can you streamline your administrative processes? The answer is simple: Electronic Data Interchange (EDI) transactions. See below for a list of multi-payer vendor portals that can help provide a secure electronic gateway between your office and BCBSIL for the exchange of real-time member/claim-related health care data.
