Sorry you have to deal with this. Honestly do what you can to tell the doctors office you Cannot pay them a dime before the claim is approved by insurance. They have staff designed to deal with this in ways you don’t have the years of training to. If you force them to tackle insurance with hard stops before they see a dime they will find a way…

It’s all about how the fucked up the coding when sending it. And this is why I hate the healthcare system.
