North Carolina leaders are vowing to pay for hospital tests done on patients examined for sexual assault. Under the state's current system, hospitals bill a patient's private insurer for a rape exam. The state sets aside about $258,000 a year to help cover rape kit exams for uninsured people. Reimbursements, however, are capped at $1,000, even though the average bill tops $1,600. While some hospitals forgive the balance, others do not.
