Will my daughter's insurance allow us to see an out of network Chiari specialist?

I am still relatively new to being a part of the Chiari community. Sometimes I don't like to think about it because I wish it wasn't happening. I don't know if my 12 year old daughter will get worse with her Chiari. She had headaches sporadically last month but so far she hasn't had any for the last two weeks.

Right now I don't have the MRI that indicates my dd CM dx, part of my avoidance of the issue. I need to make another phone call to track down the MRI disk tomorrow. I also am going to fax paperwork to The Chiari Institute tomorrow. I just don't know if my dd child health plus insurance will cover TCI as it is an out of network provider. I am not sure if there is an in network provider that can give my daughter's CM the medical attention she needs, but will my daughter's insurance see it that way. They may think that any NL will do but I disagree. I would really like her to go to TCI. She is entering adolescence and I attitcipate her CM only getting worse. I would like her to get all the tests necessary so we can get an idea of what we are up against. Does anyone have any advice on how to deal with the insurance company? Will TCI advocate for my daughter with the insurance company? I do not have the money to pay TCI out of pocket. I can only imagine what the would cost. I try to make a tank of gas last two weeks, to give you and idea of my cash flow. I am fortunate to work close to home. Thanks again for any feedback.
