Whether for yourself, or as part of a plan for your company, I recommend “Christian Healthcare Ministries (CHM)”.
I first heard about CHM on the Dave Ramsey show. Here is another link for it:
CHM is a membership-based, nonprofit ministry through which hundreds of thousands of Christians voluntarily share to pay each other’s medical bills. Choose from one of three programs—Gold, Silver, or Bronze—and add the optional Brother’s Keeper program to protect against catastrophic medical bills.
From their website:
Christian Healthcare Ministries (CHM) is a nonprofit health cost sharing ministry through which Christians voluntarily share each other’s medical bills. It is not an insurance company. CHM is based on Galatians 6:2 (“Carry each other’s burdens and so fulfill the law of Christ”) and on the actions of the New Testament church found in Acts 2 and 4.
To be CHM members, participating adults must be Christians living by biblical principles, including abstaining from the use of tobacco and the illegal use of drugs (1 Corinthians 6:19-20), following biblical teaching on the use of alcohol, and attending group worship regularly if health permits (Hebrews 10:25). There are no restrictions based on age, weight, geographic location or health history.
I think CHM is by far the best value out there for healthcare. It is what we have.
