Electronic Data Interchange (EDI) Transactions

The fastest way to conduct business with Blue Cross and Blue Shield of Montana (BCBSMT) 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

Online Eligibility & Benefits (270/271) and Claims Status (276/277) transactions may be conducted almost continuously, with the exception of Sunday, 7 p.m. to 11 p.m., MT.*

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

Getting Started

  • Participation in all electronic options available to BCBSMT providers is strongly encouraged. See the E-Commerce Connections menu below for more details.
  • 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.

Checking eligibility and/or benefit information is not a guarantee of payment. Benefits will be determined once a claim is received and will be based upon, among other things, the member’s eligibility, any claims received during the interim period and the terms of the member’s certificate of coverage applicable on the date services were rendered.
