On January 1, 2010, Blue Cross Blue Shield of Arkansas became the Home Plan for all Wal-mart associates nationwide (except Hawaii). The local PPO network will continue to be in-network.
The Wal-mart associates received new insurance cards. Their alpha prefix is now WMW. It is very important for you to get copies of these new insurance cards and use the new alpha prefix WMW to file claims for any date of service after January 1, 2010. Please do not use alpha prefixes MRT, WLA and WMR for dates of service after January 1, 2010.
We appreciate your attention to this matter. For more information about this change, please log into My Insurance ManagerSM and submit your question through “Ask Provider Services,” or e-mail firstname.lastname@example.org.
