BCBS had a major system change and caused all claims from 4/17/21 to reject for "Billing NPI not associated with Tax-ID". After days of trying to figure out the problem, they are now requiring practices to bill with their organization name & NPI in box 33A. I was able to change that.
BCBS never entered any of the claims into their adjudication system so there is no need to bill a corrected claim, just simply rebill all of them. What is the quickest way to find all the BCBS claims dated 4/17/21 to current and either delete and rebill.
