In 2010, when federal lawmakers passed the Affordable Care Act, Minnesota health systems provided $226 million in charity care to patients who couldn't cover all of their treatment costs.
By the time Minnesota fully expanded its Medicaid insurance program as part of health law in 2014, annual charity care expenses dropped to just $164 million.
The savings point to one reason why hospitals and clinics are apprehensive about Republican control in Washington, D.C., where President-elect Donald Trump and congressional leaders have vowed to repeal and replace the health law.
"The industry is totally uncertain at this point," said Lawrence Massa, chief executive of the Minnesota Hospital Association. "Everybody is just kind of sitting back — it's hard to make big decisions now about committing resources beyond 2017, not knowing what's going to happen."
Health systems that typically include both hospitals and clinics once again dominate the Star Tribune's annual Nonprofit 100 list. The systems account for about one-third of the state's largest nonprofits but they generate more than half the revenue on the list.
The Affordable Care Act (ACA) hasn't been a make-or-break proposition for the finances of health systems, but it has driven a wide variety of changes at the state's 146 hospitals. Those hospitals, in turn, tend to be some of the largest employers and economic engines in their communities.
In exchange for the promise of more paying customers via expanded health insurance coverage under the law, hospitals agreed to smaller payments from the government's Medicare and Medicaid health insurance programs.
The bargain was highlighted in a report earlier this month from the American Hospital Association, which asserted that repealing the ACA would cause "an unprecedented public health crisis." Doing away with the law would increase by 22 million people the number of people lacking coverage by 2026, according to the report.
