Two employees of the now shuttered Rock Creek Center psychiatric facility in Lemont have been convicted for participating in a bribery and kickback conspiracy.

Wendy Mamoon, 50, of Milwaukee, the former chief executive officer, and Roland Borrasi, 56, of Burr Ridge, were each found guilty on all counts, following a three-week trial in U.S. District Court.

Mamoon and Borassi were each convicted of one count of conspiracy to offer and receive bribes and kickbacks in exchange for patient referrals and six counts of offering or receiving bribes to secure those patient referrals, said Patrick J. Fitzgerald, United States Attorney for the Northern District of Illinois.

U.S. District Judge William Hibbler set sentencing for Oct. 6.

Mamoon, Borassi and Mahmood Baig, Rock Creek’s former director of operations, were indicted in January 2007.

Baig, 58, of Bolingbrook, pleaded guilty to participating in the conspiracy and testified at the trial of his co-defendants. The jury convicted Mamoon and Borrasi of participating in a conspiracy in which Rock Creek and Mamoon made illegal payments totaling more than $565,000 to Borrasi and his medical doctors group, Integrated Health Center, S.C., located in Romeoville.

Mamoon, Baig and other Rock Creek officials directed bribe payments to Borrasi and four individual physicians employed by him at Integrated in return for Borrasi referring patients to Rock Creek, enabling the facility to obtain Medicare payments for those patients.

“Medicare insurance exists to provide health care services to patients in need. Inflating claims for reimbursement for unnecessary services diverts Medicare coverage from providers with legitimate claims,” Fitzgerald said. “When doctors accept bribes for making medical decisions, such as patient referrals, they put their own self-interest above their patients’ and such abuses of the system will not be tolerated.”

Mamoon and Borrasi each face a maximum penalty of five years in prison and a $250,000 fine for each of the seven counts of which they were convicted.
