The cost and quality of health care services can vary significantly, with high cost not necessarily indicating high quality. As consumers pay for a growing proportion of their care, they have an increased need for cost and quality information before they receive care, so they can plan and make informed decisions. Transparency tools can provide such information to consumers and others. This book examines information on cost and quality available to consumers from selected transparency tools; characteristics of effective transparency tools; limitations, if any, in the effectiveness of CMS transparency tools; and CMS efforts to expand cost and quality information available through transparency tools. The book also examines how various factors affect the availability of health care price information for consumers; and the information selected public and private health care price transparency initiatives make available to consumers.
