Look out when you go to any doctor in the Carolina Healthcare System, they do their best to scam you out of money you don't owe. I carry BCBSNC through my employer, Medicare and Medicare Supplement. Everytime I go to a doctor, I receive dunning letters claiming that I owe more money even though my Medicare statement clearly shows that I am paid in full. Eventually they adjust the bill and recognize that I have paid in full. But I have to endure the harassing and condescending phone representatives for 30-45 minutes each time while they try and figure out what is going on. You'd think after 2 years they would figure out the problem.
