Urbana, IL-based Provena Covenant Medical Center will take its case to the Illinois Supreme Court after a state appeals court last month put the nonprofit facility's tax exemption in jeopardy. The case is being watched nationally as state and federal lawmakers are attacking nonprofit hospital tax exemptions and questioning whether such health facilities are providing enough charity care. In the case of Provena, the three-judge 4th District Appellate Court panel reversed a lower court's decision that had allowed the hospital to keep its tax-exempt status in accordance with state laws.
