This office began investigating nursing homes in 1975. In 1977 its jurisdiction was expanded to include hospitals; and in 1978 it was designated as New York State's Medicaid Fraud Control Unit and was requested to investigate ambulatory care as well. To date, the office has indicted 184 individuals for Medicaid fraud and related crimes; and out of 122 completed cases, it achieved 103 convictions. In addition, over $6 million were recovered through criminal prosecution; and $64 million were identified in Medicaid overstatements. The report covers nursing homes, hospitals, ambulatory care, patient abuse, and special inquiries. Other topics include adult homes, civil recovery, legal issues, special projects, and conclusions and recommendations. Footnotes are included. Appendixes contain charts of recoverable Medicaid funds and of a kickback scheme, guidelines for the central filing system, and a status report.
