Cornerstone Health Benefits is now Security Administrative Services (SAS)
Regarding logging into the website:
The identity changes from CBA to SAS will be gradually taking place as we move through the year.  One of those changes is the website.  Employees who use our LIN access to monitor their claim activity will see the screen below.  Under the drop down for “Members” there will be reference to SAS Members and Cornerstone Members.   Your employees will click on Cornerstone Members and will be given access to their PPO Network options, Prescription Drug Information and Access to their Claim Information.  The user names and passwords your employees have used in the past will not change with the transition to this new website.
