ANN ARBOR, Mich., June 27, 2008 -- The Healthcare business of Thomson Reuters has been selected to assist in providing data analysis services for Kentucky's Medicaid fraud detection program.

Thomson Reuters will provide these services as a subcontractor to Health Care Excel -- a healthcare utilization management and quality improvement organization. Health Care Excel is providing Surveillance and Utilization Review Services (SURS) to the Kentucky Medicaid program.

The contract was awarded following a competitive procurement process. It will extend for 27 months if all options are exercised.

All states are required to ensure proper and efficient administration of their Medicaid program through SURS. This includes the analysis of medical claims and healthcare delivery patterns to identify unusual billing practices -- such as inconsistent, excessive, duplicative, or otherwise suspicious claims.

"We are pleased to be working with Health Care Excel to provide the Commonwealth of Kentucky with enhanced intelligence in how to detect and prevent Medicaid fraud and abuse," said Jon Newpol, Thomson Reuters executive vice president. "This is an important effort by the Commonwealth to ensure tax dollars are spent wisely, and we are proud to be part if it."

Twelve states use Thomson Reuters' capabilities for fraud detection. Thomson Reuters also provides fraud detection services for a variety of Medicare and Medicaid programs nationally.
