– Premiums in the nongroup market (for individual policies purchased through the marketplaces or directly from insurers) would increase by 20 percent to 25 percent—relative to projections under current law—in the first new plan year following enactment. The increase would reach about 50 percent in the year following the elimination of the Medicaid expansion and the marketplace subsidies, and premiums would about double by 2026. …..
