No part of medical billing whatsoever would fly most anywhere else. It's batshit crazy, top to bottom. Go get service at one place, get fifteen damn bills from five people & companies spread out over three months plus a pile of mail that looks like bills but may say it's not a bill, and then several will have errors requiring back & forth to correct, you'll get a refund then have to pay more, pay more then get a refund, all kinds of nonsense, you're acting as a go-between for insurance and the providers because they're all friggin' incompetent and that means hours and hours on hold, finally six months later it's all settled but you're guaranteed to have missed something in all that mess and now you've got a letter from a collection agency for a $48 bill out of thousands paid.
Fuck the whole thing, I hope it all burns to the ground. It makes me so very unhappy every time I have to deal with it.
