For the past four years, CBS News has been committed to investigating healthcare fraud throughout the United States. Our reporting has uncovered schemes preying on veterans, cancer patients, rural communities, and opioid addicts. We've been the only network to expose con artists defrauding billions from private insurance companies, Medicare and even Tricare, a component of the military health system. In 2016 we produced an investigative series that found compounding pharmacies were collecting prescriptions for pain creams and billing insurance more than $1 million per week. Last year, our reporting revealed an insurance scheme involving genetic testing that cost the Pentagon trillions. This year's entries continue our work to expose unscrupulous actors bilking insurance to cash in on the American healthcare system. Our stories go beyond examining the fiscal toll of insurance fraud, they illustrate the human impact these practices have on communities, families, and individuals.
