Florida physicians have made the argument for years: The state's Medicaid payment rates are so low that many doctors wouldn't take patients covered under the program. But the federal Affordable Care Act provided a temporary solution. In 2013 and 2014, the law calls on the federal government to spend hundreds of millions of dollars to boost the pay of primary-care physicians who provide much of the treatment for low-income Floridians enrolled in Medicaid. Now, however, Florida lawmakers and doctors face a dilemma. The federal government will stop covering the full cost of the physician pay increases at the end of next year.
