Sure, but it's not uncommon, either. If you ever find yourself in a fight with a chronic or long-term condition, check the statement of benefits your insurer sends you every month. They're denying massive amounts of things that you never get a bill for. I even asked my main surgeon's office manager about this once, and he explained to me that insurance companies don't have any sort of upfront published caps on what they're willing to pay and for what, so both sides are kind of winging it. The providers simply bill some very large number that they know is so ridiculous that it has to be larger than the max that will get reimbursed, figuring that by doing so they'll at least guarantee they get that max and not inadvertently sell themselves short.

So when you see things like a $14,000 charge for someone consulting over video for 10 minutes of work, or $800 for a bandaid, and you wonder how the hell a charge can possibly be that high, the answer is often that it isn't. That's just an artifact of this blind bidding thing going on between providers and insurers where providers send the largest conceivable bill they can to insurers knowing damn well they won't actually get that much.

This also feeds back into why insurance companies have such a horrible incentive to default deny everything. They know the providers are overcharging and charging for bullshit. Both sides are forced into taking equally extreme baseline negotiating positions by the total lack of pricing transparency.

It points at a very specific dysfunction of our system that goes well beyond the question of whether the government or private insurance purchasers should bear the bulk of the cost. This is a totally separate and orthogonal problem that both buyer and seller, no matter who they are, treat all transactions, no matter how mundane, like it's a blind silent auction for a rare Vermeer that hasn't seen a public market in 300 years.
