Fax Number Correction for Government Programs Claims

Posted January 26, 2017

In our December 2016 Blue Review, we published an article titled, Government Programs Claims Handling and Post-adjudication Process Changes, Effective Jan. 1, 2017. This article included an overview of changes related to claims submitted for Blue Cross Medicare AdvantageSM and Blue Cross Community OptionsSM, or Blue Cross and Blue Shield of Illinois (BCBSIL) Medicaid, members. Please note that the new fax numbers for paper claims referenced in this article were incorrect and should not be used. Government programs claims may not be submitted via fax. The new mailing addresses for paper claims included in the article were correct. 


BCBSIL encourages electronic claim submission to help expedite processing. It is important to use the correct Payer ID on your electronic claims to help ensure proper routing of these claims. 

  • The Payer ID for electronic Blue Cross Medicare Advantage claims is 66006. If you use a vendor other than AvailityTM or Passport/Experian for electronic claim submission, contact your vendor to confirm they are using Payer ID 66006, rather than assigning their own unique number.
  • The Payer ID for BCBSIL Medicaid claims is MCDIL for Availity and Passport/Experian users. If you use a vendor other than Availity or Passport/Experian, contact your vendor for the correct Payer ID to use on electronic claims submitted for BCBSIL Medicaid members.
