In this Tuesday, Oct. 24, photo, Richard Rivera lies in his Saint Anthony Hospital bed a few days after arriving sick from heroin withdrawal in Chicago. His public health insurance would cover three days in the hospital's new medical detox unit. Hours later, just moments from going to a sober-living facility, Rivera complained of chest pains that took him away from the watchful eye of the medical detox staff. (AP Photo/Charles Rex Arbogast)
