We do apologize for the confusion. The restricted states have recently changed and the quoting tool is being updated accordingly. The GreenCover Plan is no longer available for purchase with a Colorado address. That being said, you can still purchase the GreenCover Plan with a non restricted state address (such as a family members address in another state, or a home country address), and use it in Colorado, without any problem. As a green holder, travelling to the USA for a short time, you can also consider the Diplomat America Plan. This plan is very similar and does not have any state restrictions.
Insurance rates are regulated by law. You can't find the same insurance plan for a lower price anywhere else
