Insurance companies have a major stake in the national discussion on the cost of drugs. They’re usually pitted against big pharma and biotech, looking for ways to save money on care and drugs. One recent savings trend has been a push by major insurance companies to divert members from going to brick and mortar pharmacies like CVS Health Corporation (CVS) and Walgreens Boots Alliance , Inc. (WBA) and place them into mail-order pharmacies. By having drugs delivered to doorsteps instead of picked up at pharmacies, insurance companies can leverage their buying power and exercise even better control over what brands of drugs are utilized through a single, preferred distribution network. This could result in hundreds of millions of dollars in savings, cutting out countless middlemen who all play transactional roles in a fractured healthcare system. It could also tear the foundations of traditional brick and mortar pharmacies around the nation.
