Cignas insurance policies include $4 billion in Medicare payments and a separate $2 billion payment for claims for a federal health care program called Medicare Advantage.
Cigna is under investigation by the Treasury Department for violating the Medicare program and the law, which requires it to disclose any payments it receives for Medicare Advantage and Medicare.
The federal government said in a statement on Monday that it would pay Cignan $4,717 million.
The company said the settlement includes an $872 million payment to cover claims from its Medicare Advantage policies.
The payment covers claims that were made between September 2017 and March 2018, and the company said it plans to repay the rest of the payment.
The government also said it would make payments of $8 million each for Medicare and Medicaid claims.
The payments are for claims that are made between October 2017 and February 2018, with the government paying an additional $1 million to cover Medicare claims made between February 2018 and March 2019.
Cignas is a unit of UnitedHealth Group Inc., the nation’s largest health insurer, which is the parent company of Cignum, the nation ‘s second largest insurer.
UnitedHealth Group was fined $2.4 billion by the U.S. government last year for misleading Medicare and other health care programs.
