I just got blood work done a couple of weeks ago and even though I didn't have a problem at that time, I do now; because labcorp isn't one of my insurance providers and I will get billed in full. Don't get me wrong, it is my responsibility to check if they are in network providers BUT... you would think the labcorp people at the time of taking your insurance ID and drivers license would let you know they aren't in contract with your insurance.
Shame on labcorp and its poor practices, very disappointed.
