I don't know how US works, but anywhere in Europe doctors making any sort of mistake can and are sued to hell, my wife is one of them (luckily only once and error was done by her senior doctor not herself).
Now depends what happened, how much you sue for, but losing license and ending in jail are not impossible results. Its up to judge to decide. If that's not skin in the game then I don't know what is. Compared to 99.9% of IT folks who at worst can lose their jobs and move on (not ideal situation of course, but incomparable pressure for relatively similar compensation).
This definitely is the case for medical procedures and surgeonts carry high insurance for this. Not sure how this would work for diagnosis though. It's harder to know you were misdiagnosed and even harder to proof they could have done better with the information available at the time.
