I haven't noticed this too often, however a few times it has come up, some doctors' office do not understand if they are a contracted provider and agree to accept the contracted amount, they cannot balance bill you for the difference (excepting copays, non-covered services and deductibles). When I come up against this, I usually send a letter to my insurance company stating so and so doctor is balance billing and send a copy to the doctor's office (that is if the doctor's office is not willing to take the charge off). This usually motivates the doctor's office to remove the charge asap as they probably have other subscribers from your insurance who they have balance billed as well...
