Also magnitudes off in accuracy sadly. I’ve known a few groups who’ve tried to reconcile it against actual charges and you might as well just use a random number generator.
They are trying to figure out how to have people submit their bills and gather actual billing data and compare what actually happens with what is claimed. Gives them a better data set for comparison and evaluation and to spot 'oddities'. I imagine health insurance does the same thing...but its opaque and invisible to consumers.
