What is a billing company supposed to do?

[Guest guest]

Hi everyone,

I finally am getting my IMP going and now have had about 50-60 visits. I have

only been paid for 10. I have a billing company that tells me I can call all of

those insurance companies and figure out why they aren't paying. Aren't they

supposed to do that? On top of that, they don't seem to have a complete list of

the claims I have turned in to them. They don't return emails and when I call I

end up with more questions than I started with. So,I guess I should ditch them

but my question is what exactly should a billing company be doing for me?

Thanks for your help, as always,
