Cigna acquired CarepathRx, a major private equity-backed pharmacy that dispenses prescription drugs to nearly 10% of US hospitals.[1] The acquisition was revealed in Cigna's financial filings.[1] The move reinforces the company's bid to control more of the flow of drugs through the US health care system.[1] Cigna management has repeatedly told investors that prescription drug management is one of its top priorities since its $54 billion acquisition of Express Scripts in 2018.[1] This is an example of vertical integration, in which health insurance companies expand their activities outside the core business.[1] This industry trend is resulting in fewer firms dominating more parts of healthcare.[1]
