Preventive care: It’s free, except when it’s not

CHICAGO — Bill Dun­phy thought his colonoscopy would be free. His insur­ance com­pany told him it would be cov­ered 100 per­cent, with no copay­ment from him and no charge against his deductible. The nation’s 1-year-old health law requires most insur­ance plans to cover all costs for pre­ven­tive care includ­ing colon can­cer screen­ing. So Dun­phy had the pro­ce­dure in April. Then the bill arrived: $1,100.
