It’s not middlemen. The middlemen (managed care organizations, aka health insurance companies) earn low single digit profit margins.
In the US healthcare chain, the ranking of profit margins goes (and this is public info from public financials):
Pharmaceutical companies
Healthcare software companies (based on other software company margins)
Healthcare providers (doctor groups)
Hospitals (HCA, tenet, etc)
Managed care organizations and retail pharmacies at the very bottom.
The big one I don’t know is legal, which I assume slots between hospitals and healthcare providers, but could be higher. Those millions and tens of millions of dollar judgments don’t come from thin air.
Go ahead and get rid of MCOs, and at best you will reduce costs by 5%. That’s an objective fact. They are just allocating the very limited resources among more and more demand.
