I'm referring to what are the out of pocket costs a physician pays in malpractice insurance -- the cost they pay, even if a lawsuit is not brought against them.
If there is at least a bit of competition in malpractice insurance "the out of pocket costs a physician pays in malpractice insurance -- the cost they pay, even if a lawsuit is not brought against them" and "the cost of actual malpractice lawsuits" should be fairly close on average.
