Federal prosecutors in Texas and New York announced this week they had uncovered two massive health care fraud schemes. In the Texas case, they’ve charged a doctor and six others with cheating the government out of more than a quarter of a billion dollars in Medicare and Medicaid fees. For many critics of the government health programs, fraud allegations underscore their belief that radical restructuring is needed. Others say proposals to overhaul the programs don’t address the critical need to contain costs throughout the medical system. Diane and her guests will talk about the future of Medicare and Medicaid.
