Denied claims mean less profit for the insurer. They only get to keep a percent of what they pay to hospitals. Do you have a response to that?
One of the primary jobs of insurance companies is to vet claims. If we didnt want that, you could just make a shared bank account and let doctors and hospitals bill anything they want to it. You might save 10% on overhead, but it would collapse instantly.
If that were true then United Healthcare wouldn't have rolled out an automated system that (reportedly) denies ~90% of people regardless of their actual need.
I'm not going to stick up for UHC, which is an obnoxious company, but do you honestly believe UHC is denying 90% of claims? Have you thought the implications of that claim through?
What "problem"? You're not being clear about what you're trying to say. That a particular insurer has done bad things? Nobody was going to take the other side of that argument.
Because there is a clear legal understanding of how much profit is acceptable.
