Access to Insurance & Use of Care


CHIA measures Massachusetts health insurance coverage, access, and use of health care services, as well as evaluates the cost and medical efficacy of proposed insurance benefit mandates.

Our studies examine overall rates of insurance coverage and enrollment in major health plans throughout the Commonwealth. We also monitor trends in premiums paid to health plans, and how members utilize health care services. Through our mandated benefit reviews, we provide guidance to the Massachusetts Legislature for statewide policy decisions regarding health plan benefit levels. By harnessing data from plans, providers, employers, and residents, we provide a comprehensive, holistic picture of access to care in Massachusetts.
