Massachusetts' crippled Obamacare exchange is just the latest to throw in the towel and scrap its existing software, but health-care experts said it likely won't be the last.
Those same observers Tuesday told CNBC that almost half of the existing state-run Obamacare marketplaces could, in the coming years, end up turning enrollment operations in private insurance plans over fully to the federally run HealthCare.gov for a variety of reasons.
"Certainly, I think you will see even more states default to the federal exchange, certainly up to a half-dozen states," said Bryce Williams, managing director of exchange solutions for Towers Watson, which operates private health insurance marketplaces.
Williams also said, "I do think that the vast majority of the states on the federal exchange are likely to continue with the federal exchange." There are 36 states on HealthCare.gov—including seven that are in so-called partnership agreements with the federal government, and the remaining being completely operated by the federal government.
