The 2009 federal spending bill that President Obama signed Wednesday reverses a 2007 change that led to sharp increases in costs for students who use prescription birth control. The change, which was made in 2005 deficit reduction legislation but took effect in 2007, eliminated an incentive for drug companies to offer discounted prescriptions to college clinics and other health care providers through the Medicare program, causing students to pay hundreds of dollars more a year. The American College Health Association urged that the incentive be restored, and the Associated Press reports that now that it has, pharmaceutical companies are discussing whether and how to reinstate the discounts.
