In March, we announced that, as of April 1, 2020, Blue Cross and Blue Shield of Illinois (BCBSIL) would start implementing new electronic claim submission validation edits for commercial Professional and Institutional claims (837P and 837I transactions).*
Starting this month, duplicate claim validation edits will be implemented for commercial 837P and 837I transactions when submitted to BCBSIL. Upon implementation, you may see new duplicate claim rejection messages on the response files from your practice management/hospital information system or clearinghouse vendor(s).
If you receive a duplicate claim rejection, the affected claim will not be found in our system, as BCBSIL does not create claim numbers (document control numbers) for rejected claims. To verify real-time status of the original claim number, use the Search by Member option in the Availity® Claim Status tool. For navigational help, refer to the Availity Claim Status user guide 
on our Provider website.
If you have questions regarding an electronic claim rejection message, contact your practice management/hospital information system software vendor, billing service or clearinghouse for assistance.
*This new duplicate rejection edit does not apply to Medicare Advantage or Illinois Medicaid electronic claim submissions.
