MassHealth succeeds in expanding coverage for adults

This study provides the first rigorous evaluation of the impacts of MassHealth, Massachusetts' ambitious effort in the late 1990s to expand coverage to the entire low-income population. We find clear evidence that MassHealth led to an expansion of insurance coverage relative to what was happening to similar populations in comparison states. The success of MassHealth provides support for the value of investing in ambitious new state efforts to find effective strategies to reach the remaining uninsured populations. While current budget shortfalls have forced many states, including Massachusetts, to scale back their expansion efforts, the current economic downturn is not permanent. Understanding the impacts of the expansion efforts in Massachusetts adds to the base of knowledge that will be critical for guiding states when the economy recovers and the resources needed for expansion again become available.
