DENVER, CO - MARCH 26: Registered nurse Susan Eager pays a house call visit to a patient on March 26, 2012 in Denver, Colorado. The Supreme Court began hearing three days of arguments over the 2010 health care overhaul Monday which will affect the entire health industry. Eager works for the Dominican Sisters Home Health Agency, a non-profit that performs thousands of home visits each year for needy patients. The agency, funded by private donations and grants, says it helps keep patients living in their homes longer, saving federal programs like Medicare millions of dollars each year. It provides home health care without charge to people with chronic diseases and gives preventative services usually not currently covered by insurance.
