Sarah Barazza doesn't have health insurance, but all her costs were recouped for her 15-month-old son's emergency room trip last year, including the ambulance ride.
The Barazza family belongs to a health care sharing ministry, a religious nonprofit in which members pay for one another's health care needs.
"Wow, I'm so grateful I don't have to worry about finances," the Plainfield, Ill., woman said. "I'm just focused on taking care of my child."
Compared with traditional health insurance premiums, ministries' monthly member costs are often much lower, and the option was an exception to mandated insurance coverage under the Affordable Care Act.
Members must often commit to religious principles to join the cooperative groups. The ministries generally won't pay for services that don't align with those principles, including abortion and substance-abuse treatment. They also often limit coverage of pre-existing conditions and prescriptions.
It's hard to say exactly how many people take part in the ministries, but the IRS estimates that in 2016, more than 330,000 people claimed the exemption to the health insurance mandate.
Although participation in and the number of ministries have grown since the ACA, some of the ministries have been around for decades. Beyond restrictions on the type of care covered, they also are not regulated and subject to the standards of health insurance.
"They're not insurance," said Karen Pollitz, a senior fellow with the Kaiser Family Foundation. "There's no contract. This is just a group of people who say God wants us to pay for each other's medical bills, and then they either will or won't send money."
