The House and Senate plans are essentially the same for the first year, but take different approaches after that. Both start by using private insurance for eligible adults already on employer-sponsored plans and enroll others into the state's managed care program. The House continues that for two more years while the Senate shifts people onto the exchange.
Both plans would require federal waivers and would end the expansion if federal financial support fell below promised levels. The Senate would give the government one year to approve its use of the marketplace or the expansion to adults would end.
The Senate plan also would end automatically at the end of three years when federal funding begins dropping unless the Legislature reauthorized it.
The main sticking points to a compromise are the length of time allowed to obtain a waiver before adults are sent to the marketplace and whether all the adults or just those earning between 100 percent and 138 percent of federal poverty limits must use the marketplace.
An estimated 49,000 poor adults in New Hampshire would be eligible for Medicaid under the federal health overhaul beginning next year, but legislative authorization is needed to enroll them.
