I completely agree about it being the providers responsibility. The problem is, they don't want to do anything to resolve the issue either. Other times, it doesn't even involve the provider, they did everything right but for some byzantine reason it didn't go through the insurance system correctly and you have to call them and tell them to process it the same way they have processed every other exact same bill from the exact same provider.
Just wanted to vent. I should clarify I live in the US (as if that wasn't clear from my post LOL!)
Completely agree. Just had to vent.
