US bees with insurance: How was your maternity care covered/billed? Did you have one flat fee you were charged? Or just a percentage or flat rate for each thing, with it's own bill?

I haven't gotten to the whole labor and delivery part, but I'm getting so frustrated with all the little bills I get-- $14 here, $23 there, $200 for lab work... I know I'm going to meet my max out of pocket, and I'm planning for that, but it takes a lot of time just to keep up with all the little bills, checking them against my insurance EOB, etc. I wish they would just send me one bill at the end.

Plus, of course I started the pregnancy at the end of 2012, so I paid up to my deductible there then started over at zero for 2013, but that's just another annoying story. I'm not even complaining about how much I'll have to pay at the end of the day, just the *way* I have to pay it all. I'm grateful to have good insurance, but it sure is annoying.
