Had the exact same thing happen except my bill was only for $1800 after insurance. The kicker was that when I called the insurance company to ask about the cost they told me that it was unknowable in advance because they have rates negotiated with each hospital individually. When I asked if there was any way to estimate my out of pocket expense of if there was any cap they told me no. So, there's literally no way to know what it's going to cost, at least with blue cross, because the rates are negotiated on a per facility basis and not public. Not really a free market for sure.
