PEIA will change Pharmacy Benefit Managers from Express Scripts to CVS Caremark on July 1, 2016. CVS Caremark is a pharmacy benefit management company providing pharmacy benefit management to millions of covered lives nationwide. Although CVS Caremark is affiliated with CVS Pharmacy, PEIA members are not required to use CVS pharmacies. CVS Caremark’s network includes all of the major chain pharmacies and most local pharmacies. Any PEIA member whose current pharmacy will not be in the CVS Caremark network will receive notification and a list of in-network alternative pharmacies in advance of the change on July 1. The change to CVS Caremark will also bring changes to the formulary. Affected members will be notified.
