Opinion: We need benchmarking, not arbitration, to quell surprise medical billing

Surprise medical bills expose Americans to the high prices and occasional greed lurking in the heart of our health care system. Medical insurers typically provide some insulation from these bills by negotiating prices for their in-network patients. In its effort to fix surprise bills, Congress must not undermine this key lever for controlling hospital and doctor bills by instituting an arbitration solution, which is strongly backed by organized medicine, that is now working its way through several Congressional committees.
