The professional and facility payer ID grids contain valuable information to 
assist you in claims submission, including prefixes, payer information, and 
claims mailing addresses by product.
The grids have recently been updated to reflect an additional prefix for the 
Account-specific National PPO product.  Please be sure to download the most 
current versions, which are available on our  Electronic Data Interchange (EDI) web page under EDI 
Resources.
