In one of the first False Claims Act settlements involving Medicare's Prescription Drug Program, known as Part D, RxAmerica LLC. has entered into a civil settlement agreement with the United States in which it has agreed to pay the government $5.25 million to resolve allegations that it made false submissions to the Centers for Medicare & Medicaid Services (CMS), the Justice Department announced today. RxAmerica, a wholly-owned subsidiary of CVS Caremark Corporation, provides prescription drug benefits to Medicare beneficiaries pursuant to a prescription drug plan. The Medicare program offers Part D participants prescription drug coverage. For Medicare participants to obtain this drug coverage, they must join a Medicare-approved plan, often referred to as a Part D plan. Medicare Part D plans can vary in both the drugs that they cover, the amount they reimburse for those drugs, and the deductibles and co-pays they require their participants to pay.
