The New Hampshire Comprehensive Health Care information System (CHIS) was created by NH state statute to make health care data “available as a resource for insurers, employers, providers, purchasers of health care, and state agencies to continuously review health care utilization, expenditures, and performance in New Hampshire and to enhance the ability of New Hampshire consumers and employers to make informed and cost-effective health care choices.” The statute also required that the New Hampshire Insurance Department (NHID) and the NH Department of Health and Human Services (NH DHHS) partner on the project. The same legislation that created the CHIS also enacted statutes that mandated that health insurance carriers submit their encrypted health care claims data and Health Employer Data and Information Set (HEDIS) data to the state.

NH DHHS, Office of Medicaid Business and Policy, after a competitive bid process, contracted with the Maine Health Information Center (MHIC) in July 2005 to implement the CHIS. Under the contract MHIC is acting as DHHS’s agent for the collection of claims and HEDIS data, is also providing a series of reports and studies for DHHS that examine the NH Medicaid program in concert with using the commercial data for benchmarking, and is hosting this website.
