Electronic Commerce

The fastest way to conduct business with BCBSOK 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 (ANSI 835 EFT)
  • Electronic Remittance Advice (ANSI 835 ERA), or delivery of claims payment information

Getting Started

Establish a vendor connection. Some electronic transactions, such as EFT, may be set up directly with BCBSOK. For other EDI transactions, you will need to enlist the services of a third-party electronic business vendor, such as Availity® Essentials

  • Availity Essentials – To register with Availity or learn more about services available to BCBSOK providers, visit the Availity website, or call Availity Client Services at 800-AVAILITY (282-4548).


  • Prior to conducting EDI transactions, you will need to confirm services are available and register with your selected vendor.
  • In some cases there may be a fee for services. We encourage you to “shop around”!
  • 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. It is your responsibility to obtain and follow EDI transaction standards specified within the current ANSI X12 837 – ANSI 5010 Technical Reports Type 3 (TR3). For details, refer to the X12 site.
