A health care sharing ministry is an organization that facilitates sharing of health care costs between individual members who have common ethical or religious beliefs in the United States. A health care sharing ministry does not use actuaries, does not accept risk or make guarantees, and does not purchase reinsurance polices on behalf of its members. Members of health care sharing ministries are exempt from the individual responsibility requirements of the Patient Protection and Affordable Care Act, often referred to as Obamacare. This means members of health care sharing ministries are not required to have insurance as outlined in the individual mandate.
