So DH may be transferred to the States in the coming months. I'm a bit hesitant to leave (Canada) for a few reasons, but one reason I hadnt considered was the cost of giving birth and other medical expenses.

I assumed that since we would have insurance under his company that pregnancy and birth expenses would be covered 100% as it is here. I've now seen a few posts where people have paid a few thousand dollars for their hospital stay even after insurance!! Is this typical or does it vary based on insurance coverage?
