About the HCCI Methodology
HCCI’s research activities are based on de-identified data voluntarily provided by four of the nation’s largest insurers (see Data Contributors). These insurers have agreed, for the first time, to share their data with HCCI, in compliance with applicable privacy laws, both for these reports and for making data more available to researchers to study what influences use and costs of health care services in the United States.
Large quantities of private claims data are needed for a more complete picture of the entire health care system than can be had by looking at publicly available data. Few researchers have access to private claims data, and then generally from only one commercial insurer. As of October 2016, HCCI held commercial claims representing the health care activity of more than 50 million individuals per year for the years 2007 through 2015. The claims used in the 2015 report (approximately 3.7 billion claim lines) represent the health care activity of over 25 percent of all individuals younger than 65 and having ESI, making this one of the largest data collections on the privately insured ever assembled.
HCCI’s data will provide new, critical information to the public about health care costs. We invite additional insurers and other holders of similar data to join this innovative and unique voluntary collaboration between the payers of health care costs and researchers.
