I've had numerous encounters where doctors (and dentists) attempt to charge me for services they've already been reimbursed for from the insurance company. It's only after hours of scouring my EOBs and being on the phone with my insurance that I then come back to the practice's office with evidence in hand, and they dismiss the charges. I'm pretty sure this is just a racket because they expect most people not to put up a fight and just pay, or get sent to collections hell. The amount of work you need to do as a patient in our health system is so dumb.
