Insurance is defined at its core as a transfer of risk. Its that simple. If insurance denies everything I send their way while I am paying them, its no longer a transfer of risk, I am simply paying someone to tell me 'no'.

That out of the way, the whole health insurance industry does not follow the concept of transfer of risk. The insurance companies rather follow the concept of transfer of action. Basically I am not going to spend all day negotiating with a hospital. That said, them denying is because they do not want to do the work still, so in other words, I am still paying someone to tell me 'no'.

In both concepts, the insurance companies are not doing what they ascribed to. Along with the laws that congress stripped away affordable care to its basics that we all are required to have it - read an extra tax but to corporations who give kick backs to their congressional lackeys - and the fact that insurance companies basically are price fixing all the rates and such, it becomes a lose (you)/lose (you)/lose (hospitals)/only ones who win are the companies.

Late stage capitalism hard at work.
