For context, in the US, insurance companies are required to pay out a certain percentage of premiums in the form of care. UnitedHealthcare got around this by opening their own pharmacy, OptumPharmacy, and then inflating prices there so that the profits would land in the pharmacy part of the business, instead of the insurance part. The did pretty much the same thing with a number of medical practices, where they wouldn’t pay enough for doctors to stay in business…but would then buy the office, and pay higher amounts to themselves. This has the feeling of a revenge killing by somebody hurt by these practices, though we don’t know for sure.
