In the United States, wide variation in prices for the same medical services continue to persist both across the country and within geographic areas, with no reliable correlation between clinician prices and quality. Helping patients and physicians identify and select high-quality medical services at the lowest price when services are needed is frequently touted as a key tactic for improving clinical and financial outcomes for patients and for increasing the value of health care spending. While quality of care information has become mainstream, accurate health care price information is only beginning to be made available by federal and state policymakers, payers, and practitioners.
