Anthem will implement system upgrades between July 10^th and July 14^th. This will replace Anthem’s legacy internal provider data management system for Connecticut contracted providers. This technology upgrade is being performed to improve provider data accuracy and transparency. Provider updates submitted during this time will be processed after July 14^th. 

With this system upgrade, all data fields on a claim are used to build the claim record and submitting claims with complete and correct data is critical to ensure Anthem is able to process the claims efficiently and accurately.

Effective July 16, 2021, claims submitted with missing or incorrect billing national provider identifier (NPI) will be denied.
