Where does "states are over reporting cases (of virus) to get more funding" come from?

Iowa Sen. Joni Ernst seemed to embrace on Monday a thoroughly-discredited QAnon conspiracy theory about U.S. deaths from COVID-19 being a mere fraction of what has been reported. As Amie Rivers of the Waterloo Cedar Falls Courier reported, Ernst said she was “so skeptical” of the official death count when asked by an attendee if the government was over-reporting coronavirus deaths.

“They’re thinking there may be 10,000 or less deaths that were actually singularly COVID-19,” Ernst said, seemingly referring to the debunked conspiracy theory that only around 6% of COVID-19 deaths were due to the virus. “I’m just really curious. It would be interesting to know that.”

Going even further, however, Ernst also suggested that doctors were intentionally falsifying coronavirus cases in order to receive more money for caring for the patient.

“These health care providers and others are reimbursed at a higher rate if COVID is tied to it, so what do you think they’re doing?” she questioned the crowd.

Ernst, who made the comments during an event in Black Hawk County with State Rep. Ashley Hinson, told the Courier that she had “heard the same thing on the news,” but wasn’t positive that was the case.

The reimbursement rate theory has been around since early this year, ever since a Minnesota legislator made the claim in a Fox News interview. However, as FactCheck.org wrote, “multiple experts told us that such theories of hospitals deliberately miscoding patients as COVID-19 are not supported by any evidence.”
