Blue, I don't see anything about NFP plans but I do recall reading some of the early post-mortem's on Ocare and there were references to not-for-profit organizations. This was made mostly on the assumption that for-profit companies charged higher premiums than NFP.
I don't know how many NFP Blue's are still around but some of the HMO's are NFP and I believe some ACO's also were set up as NFP.
