Insurance fraud expert witnesses may testify on health care fraud, insurance claims, medical insurance, and correlated matters. In the news this month, Angela Shae Ellison, 45, was charged in Des Moines, IA, with defrauding Medicaid and health insurers of more than $700,000, for medical services that were never performed. The US Attorney’s Office for the Southern District of Iowa says Ellison submitted false insurance claims to Medicaid, WellMark Blue Cross/Blue Shield, Aetna and United Health.
