As much as I hate the in-network vs. out-of-network concept because of the risk to the patient, this story is a good example of why some providers are in-network. The in-network providers are (or should be) less likely to overbill because they have negotiated contracts with the insurance companies. Providers that don't have a contractual agreement with insurers are therefore out-of-network.
