Elizabeth Warren and Josh Hawley introducing a bill Tuesday to break up "Big Medicine,"

snip:
The bill targets large health companies, like UnitedHealthcare or CVS Health, that own or control various parts of the health care supply chain, from the physician's office to the pharmacy to the Pharmacy Benefit Manager.

UnitedHealthcare, for example, owns Optum Rx, a PBM that negotiates drug benefits and discounts. CVS Health owns the PBM CVS Caremark, and they also own the insurance provider Aetna. Optum, Caremark, and ExpressScripts are the top three PBMs that manage nearly 80% of prescription drug claims

The lawmakers argue that by "controlling both the company that pays for health care services and also the entity that sets the prices for those health care services" these healthcare companies "may be steering business to their own providers, evading laws intended to rein in corporate profiteering, or using physicians they employ to boost government payments to their insurance arms." They also point to the ways the consolidation leaves independent pharmacies unable to compete.

United Healthcare should not be allowed to own Optum Bank who controls assets of 1000s of medical provider organizations. Cigna sells insurance and owns express Scripts.
