This NPR article has been sitting in my browser so long that the newly passed reform bill may have made it obsolete, but I am finally motivated to discuss it. Only one collective is described. Members pay a modest annual fee to cover administrative expenses, then write monthly checks to other members as directed by the administrators. There is what appears to be a co-pay or per-need deductible of $300 (for lack of more specific terminology), and it is waived after a household pays it three times within 12 months for the remainder of the 12-month period. Members can voluntarily choose to help people whose needs exceed $100,000, or who have been injured in motor vehicle accidents.
This is an interesting experiment. It frighteningly mimics only basic catastrophic coverage, and payments are not assured. Pre-existing conditions are generally not covered, including most pregnancy costs. Is this a good idea?
It's easy to understand. There are about 30 pages of straightforward rules and instructions. There is one deductible rule. There is only one type of plan (not counting the two optional add-ons for motor vehicles and >$100,000 needs). The organization is compassionate. Membership in the collective is not exclusive of having other insurance, so the collective may end up being helpful to someone who is "underinsured".
With about 14,000 households spread across the United States, the collective lacks strong negotiating leverage to demand lower prices from care providers. Members who rely on the collective are self-pay patients, so they will be charged much more money than a large insurance company would be charged, increasing the burden to members via premiums (the premium to need ratio is less efficient for a small collective than a large insurance company, which is also why single-payer systems are so good at keeping costs low).
Payments are not assured, and would become less likely as needs increase. Small groups are more likely than larger groups to experience significant variance in needs from time to time. Large companies tend to have reserves that they can tap if there is a spike in health care consumption, but the collective is set up rigidly. The NPR article mentions that a vote of the membership is needed to increase premiums, reducing flexibility and security.
Health economics studies have consistently shown that people tend to gravitate towards plans with the lowest premiums, despite their risks or needs. Neuroeconomics has shown us that most people are terrible at making decisions when there is a lot of confusing information and a lot of choices, and they tend to focus on select pieces of information to the exclusion of other important factors. Keep that in mind: more choice is not necessarily better, and is often very bad, especially for the more ignorant and less intelligent who are also at higher risk for other problems in their lives. When shopping for health insurance, with all the many complicated plans, people tend to focus on premiums to make the decision easier. The collective has such a low premium (2/3 of what I pay for my bare bones plan) that it may attract people for whom joining is a terrible decision, and who are more likely to incur greater costs for the collective.
Finally, what are the effects of only including devout Christians? Very generally, when you ignore factors like church attendance, self-identified Christians are more likely to have health problems and engage in dangerous or criminal behaviors than atheists. Samaritan Ministries seems to have some decent safeguards up to protect itself, though. Members' pastors are involved in their membership, and the collective simply does not cover many things (substance abuse, STDs may be difficult) that are out of line with their stated values. I wonder if there are also impacts due to changes in the age composition of devout church-attenders. I wonder if the collective attracts a disproportionate number of elderly who use it to supplement Medicare, and how that affects the risks.
I like experimentation and innovation. I am curious to see how a project like this works over time. I also think it is very risky, and may need additional safeguards. Ideally, risk would be shared in a national plan that assures some basic levels of coverage to everyone, and collectives like this or private companies would sell supplemental plans.
