So let's say I need a blood test done. The practice charges $100 dollars. I can then call my insurance provider and ask how much of that $100 they pay. If they say they'll pay $80, I could look at another practice that charges 90 or 80 etc... I know this doesn't cover everything but there are standard things that it could be applied to.
I understand it's not as simple as I'm trying to make it sound, but there has to be a way to gain progress
