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 additional prefixes for the
Account-specific National PPO and Third-party administrators products. Please
be sure to download the most current versions, which are available on
our Electronic Data
Interchange (EDI) web page under EDI Resources.
