CVS Health’s merger with Aetna this year did not come easy as there was a federal hearing of the acquisition. At a healthcare conference in January, Merlo said CVS planned to expand and add new services to treat chronic diseases. CVS, with the help from Aetna’s data on member’s health conditions, plans to have 1,500 HealthHUBS, which help patients manage their health between doctor appointments, in stores by the end of 2021.
