Florida and federal agencies are cracking down on corruption in the state's Medicaid program after revealing $124 million in improper payments and more than $56 million in fraud and abuse last fiscal year. The Center for Medicare & Medicaid Services said it had revoked the billing privileges of more than 1,100 medical equipment suppliers in South Florida and Southern California and suspended payments to home health agencies in Miami-Dade County. It also said it would require certain suppliers of medical equipment, prosthetics, orthotics, and supplies to post a $50,000 surety bond this year.
