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.

This is the second time on this thread you've pasted this Newsweek link as a rebuttal. I don't understand why you think it rebuts either argument.
