A whistleblower lawsuit alleges that UnitedHealth Group, and health plans that hire a subsidiary of the insurer, have overbilled the federal Medicare program by submitting risk adjustment claims in ways that wrongly boost payment rates.
If true, the scheme could have caused hundreds of millions, if not billions, of dollars in government overpayments to health plans, according to a lawsuit unsealed last week after the U.S. Department of Justice said it would join the case.
Matthew Burns, a spokesman for UnitedHealth, denied the allegations, saying in a statement: “We reject these more than five-year-old claims and will contest them vigorously.”
The whistleblower case focuses on Medicare Advantage health plans that are operated by private insurance companies to manage care for people covered by the government program for people age 65 and older.
Medicare health plans make payments to doctors and hospitals when enrollees use services. The government, in turn, pays the health plans a set per-member, per-month rate that’s meant to cover health care costs, plus the insurance company’s overhead.
At issue in the lawsuit are the government payments, which are adjusted upward for insurers that happen to cover patients with more costly health problems. Rules surrounding risk adjustment have been controversial in the past, with UnitedHealth in January 2016 suing the federal government over a change in guidance on how to assess the health status of enrollees.
The lawsuit alleges that insurers boosted risk adjustment claims by submitting claims for diagnoses that health plan members didn’t have, or for which members weren’t treated in the relevant year. Insurers also claimed that members were treated for more serious conditions than they actually had, according to the lawsuit.
Finally, health plans refused to correct claims submitted to the government, the lawsuit says, and reimburse Medicare.
Other health plans hired a UnitedHealth subsidiary called Ingenix for risk adjustment services, the lawsuit says. It claims that Ingenix also provided the service to UnitedHealthcare’s Medicare Advantage plans, which cover about 2.2 million people.
Ingenix, which is now called OptumInsight, is UnitedHealth’s business for health care data analytics. Through the subsidiary, UnitedHealth “engaged in systematic fraud by assisting and causing (Medicare Advantage) organizations … to submit fraudulent risk adjustment claims,” the lawsuit states. “Through this fraudulent scheme, defendants have defrauded the United States of hundreds of millions — and likely billions — of dollars.”
Burns, the UnitedHealth Group spokesman, countered that his company, headquartered outside Minneapolis, is “honored to serve millions of seniors through Medicare Advantage, proud of the access to quality health care we provided, and confident we complied with the program rules.”
Over the years, the federal government has joined whistleblower cases that have gone after large hospital chains on allegations that they upcoded patient cases to maximize reimbursement, said Patrick Burns, acting executive director of Taxpayers Against Fraud, a Washington, D.C., group that follows whistleblower litigation.
What’s new in the case against UnitedHealth Group, he said, is the target — a Medicare Advantage insurer — and the administration bringing the case.
“It is the first big false claims case that the Trump administration has joined, and it’s one of the very first Medicare Advantage cases that the Justice Department has joined,” said Burns, who is not related to the UnitedHealth Group spokesman. “This is a very big case. It could result in north of a billion dollars in recovery.”
