Bombs' medical costs could be in the millions

As surgeons and physicians worked to mend nearly 70 hospitalized victims of the Boston Marathon bombing, a new toll emerged: The total medical costs inflicted by the attack may eventually reach or surpass $9 million, according to a rough calculation. The precise health-care price tag won't be fully known for months as some of the injured, particularly those who lost limbs, undergo extended rehabilitation (which can cost more than $200 per hour) to re-learn walking. Much also depends on whether mental-health experts begin to see witnesses or survivors who struggle with post traumatic stress disorder.
