Escalating health-care costs and the growing ranks of the uninsured are fueling this fast-growing fraud. Before he was caught, Daniel Sullivan, an uninsured Pennsylvanian, racked up more than $144,000 in medical bills at five hospitals posing as an acquaintance whose insurance information he had stolen.

In addition, drug addicts in search of their next high — or treatment for methamphetamine-related illnesses — are committing medical ID theft, according to a report published in May by the Department of Justice’s National Drug Intelligence Center.
