Can confirm. Three births, hospital/insurance both effed up the billing on all three. If we hadn't been vigilant and wasted hours, and hours, and hours, on the phone and in one case gotten our state rep and the state insurance board involved we'd have been out several thousand dollars that we shouldn't have had to pay. I hate to think how much we didn't catch. Similar stories from others, plus tales from non-pregnancy major medical procedures that shake out similarly, though are even harder to sort out.

Everything that touches healthcare billing is scammy, incompetently managed, and often outright fraudulent. Good luck getting any compensation or justice other than what you were originally entitled to, though.
