CF is CareFirst, the brand name for BlueCross BlueShield of Maryland, DC, and Northern Virginia. It is the Plan which wanted to be bought by Wellpoint which sprung from Blue Cross of California. The Maryland Insurance commissioner squashed the deal. In my opinion, he was entirely correct. The deal was self serving to existing management, probably too low a price, and very unlikely in the best interests of the people of Maryland. Unfortunately he's left with a marginal company with poor management and a less than active, knowledgeable Board. All of which has played to the great benefit of Mamsi.
