Insurance companies basically mirror the reimbursement policies put in place by medicare. I'm sure most providers would gladly take lower reimbursement from a single provider over the chaos and pain driven by insurance companies right now.
Basically every provider does not take medicaid so I suspect you are wrong about that. Again Im not happy with the insurance situation, I just think its barely top 10 in terms of problems with our healthcare system. The bureaucracy is required because of our horrible fee for service payout system. Without getting rid of that m4a would still requires an army of billers because republicans would constantly be screaming about the government being scammed(and they wouldnt really be wrong, healthcare providers do tons of wasteful procedures and the bureaucracy is the only thing slowing that down(recent example I came across, currently we wake up obgyn's to perform emergency medically required abortion services at the hospital even though abortions can be done with a pill and the nocturnist can safely oversee the whole thing, no need to wake anyone up. This is only done so providers can charge us more money. This shit is happening constantly over and over again every time providers can find ways to nickel and dime us and patients have no choice)). We dont actually need single payer to get rid of fee for service so really I think private insurance is an orthogonal problem to the billing army.
