The Nebraska attorney general's Medicaid Fraud Unit recovered more than $20 million from fraudulent Medicaid claims filed by service providers and drug companies in 2012.

Attorney General Jon Bruning said the funds would be used to reimburse Medicaid for losses and to cover legal fees for individual cases.

Bruning said he would not tolerate false Medicaid claims that take state tax dollars. In one case, the unit returned more than $3.7 million from Abbott Laboratories, a pharmaceutical company.

The Medicaid Fraud Unit has recovered more than $64.8 million since it was created by the  Legislature to investigate Medicaid provider fraud and patient abuse in 2004. In 2011, the unit recouped more than $6.1 million.
