Kmart Corp. has agreed to pay $32.3 million to the United States to settle allegations that in-store pharmacies overcharged several federal health care programs, the U.S. Department of Justice has announced.

The settlement agreement is part of a larger $59 million settlement that includes a resolution of state Medicaid and insurance claims against Kmart, the DOJ said.

According to the Justice Department, Kmart, a wholly owned subsidiary of Hoffman Estates, Illinois-based Sears Holdings Corp., allegedly violated the False Claims Act by offering discounted generic drug prices to cash-paying customers, but didn’t disclose those cheaper prices when reporting the drugs’ usual and customary prices to Medicare Part D, Medicaid and Tricare, which is the health program for uniformed service members and their families.

A representative for Sears Holdings did not immediately respond to an emailed request for comment Tuesday afternoon. The claims resolved by the settlement were allegations only, and there was no determination of liability, according to the Justice Department.

The July 2008 False Claims Act lawsuit was filed by whistleblower James Garbe, a long-time pharmacist according to court documents. Garbe will receive $9.3 million for his share of the recovery.

“Pharmacies that are not fully transparent about drug pricing can cause federal health programs to overpay for prescription drugs,” Chad Readler, acting assistant attorney general for the DOJ’s Civil Division, said in a statement. “This settlement should put pharmacies on notice that there will be consequences if they attempt to improperly increase payments from taxpayer-funded health programs by masking the true prices that they charge the general public for the same drugs.”

The lawsuit is captioned United States ex rel. Garbe v. Kmart, but more importantly, this case should serve as a reminder that employees are watching, paying attention, and may be set to receive a huge huge payday if the opportunity presents itself.
