CVS Health

Following its acquisition of Aetna in late 2018, CVS Health now provides an even more integrated healthcare-services offering for its members. Legacy CVS combined both the largest pharmacy benefit manager, processing over 2 billion adjusted claims annually, and a sizable pharmacy operation, including nearly 10,000 retail pharmacy locations primarily in the U.S. Adding a managed-care organization with over 23 million medical members gives the company a strong position in theinsurance industry and should help CVS better control overall healthcare costs for its clients.
