35 Weeks and No Doctor...Long Freaking Story

I've known my whole pregnancy I'd have to change doctors. I didn't want to, but I can have the baby at a different hospital for free. And my OB doesn't deliver at the hospital. 
He was totally cool with me transitioning and recommended I transfer end of March, first of April so I could have a few appointments with the new office. He said come home and he'd take car of me after delivery. I'm gonna have to cross state lines to have the baby. 
I went Wednesday and met with the OB nurse. Filled out the paperwork. Gave my insurance card. Peed and had my BP taken. They made an appointment with the doctor for today. 
Wednesday night they called and said they were confused. Why did I leave my doctor so far in the pregnancy. I said I had to move to deliver at the better hospital. And billing lady was a real piece of work. She went on about me being out of network. I'm not. And that she's look into it. 
I went in today and wanted to make freaking sure I'm not out of network and that they are filing crap correctly. No joke. They lost it on me. I'm sitting in the lobby and this lady I've talked to on the phone and in the office loses it. Now, I'm trying to keep my cool and calm. 
She said this was my fault. I am responsible for making sure I can come to the office. So I told them I'd call and reassure them I was in network. I called the insurance company and they were like you're totally fine. They even offered to call the billing lady directly to confirm.
Now, this woman is going off on me in the lobby in front of everyone about how it's my fault. And finally, I asked what did she need. She said her office had needed. She said she had to call insurance and have a hour long conversation with them and have a bunch of paperwork sent to her. And that she couldn't do that in 5 minutes when I was supposed to see the doctor. 
She told me that even though insurance was willing to call her directly, she didn't have the time to establish me as a patient. (Remember I was just there Wednesday.) That the 24 hours between Wednesday and today wasn't enough time. Meanwhile, she's blaming me about out of network which I'm not. 
I told her that her office created this appointment. And she said they see hundreds of patients and she doesn't have time to push me to the top of the list. Okay. Fine. Then why did you make an appointment so soon if you couldn't establish me with your paperwork? Bc the scheduler follows the nurse and not billing. 
Okay, I drove an hour for an important appointment. Wouldn't it have been easier for you to walk across the hall to talk to your coworker than me come to a different state to sort your mess? 
So she's in a fit in the lobby and tells me I can see the doctor but because she hasn't had time to establish me as a patient, I'd have to pay $1000 today. And then have a $2900 fine if the paper work didn't come through correctly. Bc as of right now, it's like I'm not insured bc she hasn't gone through the protocols she's required to make me a patient. 
I told her I wouldn't give them a dime. I am insured. I am in network. She also told me I couldn't return to my old OB after delivery. I looke st her and said you can't hog tie me and force me back here. Period. 
She's being loud and suddenly goes on about how they have dozens of patients and the girl at the desk is new, and they don't talk to each other. 
So finally I looked at her and said, "no matter what, in network or not, I was never gonna be able to see the doctor at the appointment you scheduled because your office didn't allow sufficient time for paperwork to be filed." She said she didn't file my paperwork so it's like my paperwork doesn't exist. But that is my fault. 
Finally, she said she'd try to file on Monday and then when it was confirmed, they'd make me a doctors appointment. Again, why wasn't this the option Wednesday? 
I was embarrassed by her yelling in a public place. But she messed with the wrong momma. I'm ready to pop. And I'm not intimidated by women who are hard nosed. I know she's got a job, but I'm not dumb in protecting my family, money, or making sure we are covered. I refused to let her push me. But I'm not giving her a dime. 
Thank God she's just the billing lady and not a doctor. I'd run so fast back to my OB if I could. But this office is the only one that delivers at the hospital that I want. People move. People change doctors. And we are looking to move right after the baby and she said well whenever you move, you'll have come back here. Ummmm, if I move, I ain't coming back. 
I'm all kinds of angry. Because I left without seeing the doctor. And right now, I have no doctor. I'm too tired and too emotional to drive an hour to fight with an idiot billing lady who can't walk out of her office and communicate with the rest of the staff
