This communication applies to Medicaid and Commercial plans from Anthem Blue Cross (Anthem).


Anthem wants to help our consumers access providers who will support their health and wellness needs. To facilitate this, we maintain an up-to-date, accurate, and complete provider directory.


We need your help! Center for the Study of Services (CSS) is an independent research firm that is helping us collect accurate information. Please take a moment to review and update the information we have on file for your practice.


To review your directory profile information, go to


Using your tax identification number, sign in and access the practice profile. You will be able to review your practice’s profile information and make any changes or updates, including:

  • Network provider directory details.
  • Office details (for example, practice office address, billing address, office hours, telephone number, email, etc.).
  • Other provider details (for example, accepting new patients, hospital affiliations).


Please note, this link will be available for six weeks, beginning March 20, 2023, and ending May 1, 2023, to allow us to process any updates.
