Hospital executives in Arizona are backing a plan by Gov. Jan Brewer to expand the Medicaid program under the Affordable Care Act, reported the East Valley Tribune. The plan would include a hospital bed tax of $220 million a year that would pay the state's share of expenses for the expansion, with the federal government picking up the rest of the tab, the article noted. Under the plan, Arizona would expand its Medicaid rolls by about 240,000 beginning next year. Article
