Half of americans have group plans. Under the Republican plan,  group plans will continue to provide the Obamacare plan protections on things like pre-existing conditions. This is important in Hawaii, where by law, full time employees must receive and employer provided group plan. These plans are great and provide for things like prescription drug coverage and even annual glasses and optician charges for things like contact lenses. It is doubtful Hawaii will waive the Obamacare protections. However, if even one state opts out of the protections, then insurance companies can begin reducing coverage under employer group plans, including plans offered in Hawaii-- some Senators have said that they will not allow this in the Senate plan.
