Part B Claims Incorrectly Deleted Prior to Processing



On June 30, 2009, the Part B Multi-Carrier System (MCS) contained an invalid
National Provider Identifier (NPI) crosswalk file, which caused claims to be
deleted incorrectly. These claims require resubmission by providers. TrailBlazer
will be loading Batch Control Listings (BCLs) into the provider's electronic
mailbox to assist with indentifying the affected claims. The BCL is a listing of
claims that have passed editing in TrailBlazer's front-end processing system
(Gateway Production Network (GPNet)), but have been deleted prior to submission
to the Part B MCS for processing. An updated GPNet Communications Manual with
the file name has been loaded to the TrailBlazer Web site.



When providers receive the BCL for June 30, 2009, please rebatch these claims
and retransmit the files. These files should include claims that were submitted
to TrailBlazer from June 27–29, 2009. Safeguards have been established within
the Part B MCS to prevent this issue from occurring in the future.



Note: If you have been contacted by TrailBlazer Electronic Data Interchange
(EDI) and have already resubmitted the affected claims, please do not resubmit
the claims again.



We regret any inconvenience this issue has caused providers.
