"What they said was that the part of the expansion that would penalize states -- that would withdraw all Medicaid funding from the states if they didn't go along with the expansion -- is invalid," Landers explained. "The expansion still exists, but a state can either sign onto it or not and won't lose all its current Medicaid funding if it doesn't go along with the expansion."
While some states are already expanding their Medicaid roles and others are happy to cooperate because of the federal funding they'll receive, she said, "there are always those states who are very parsimonious -- not generous -- in granting Medicaid benefits to adults. So basically, this decision will have the effect of limiting the impact of the law in getting more adults insurance coverage."
Another expert, Robert Field, a professor of law in the department of health management and policy at Drexel University's School of Public Health, weighed in and found that each side may have gained from the decision.
