Religious Health Care Ministries Show Growth: The Wall Street Journal reports that the number of participants in religious health-sharing arrangements has grown from 200,000 to 500,000 since 2010 and after enactment of the ACA. According to the report, gov’t officials are concerned both about the risk to participants from the unregulated operation of the arrangements, and about their impact on the Affordable Care Act insurance pool. Meanwhile, ministry officials did not anticipate such growth when the groups obtained an exception to the law.
