Like other hospitals, UAB Hospital faces deep cuts in federal reimbursement for treating uninsured patients under the health-care law, he said, but won't see many new paying patients without the Medicaid expansion. On a recent evening, as a rare blizzard struck Birmingham, dozens of uninsured patients filed through the emergency room at UAB's main campus. Complaints ranged from headaches and swollen feet to broken bones. Such visits contribute to more than $100 million in uncompensated care costs at the hospital, according to 2012 Medicare data.
