It is (also) their problem. If they're in the network, they've agreed to certain terms as well.

I'm not saying skip out on your bills. I'm saying that the provider and insurance need to figure the bill out. I'm not floating a provider in my network so that I can fill out a ton more paperwork to get reimbursed eventually.

And yes, they do make errors in major ways. Just two years ago, I got as though I hadn't made my deductible. It was a $2500 difference. It's much easier to have a provider refile to get their money than for me to pay them and then work through the insurer's system to get reimbursement.
