Federal health officials made more than $16 billion in improper payments to private Medicare Advantage health plans last year and need to crack down on billing errors by the insurers, a top congressional auditor testified Wednesday.
James Cosgrove, who directs health care reviews for the Government Accountability Office, told the House Ways and Means oversight subcommittee that the Medicare Advantage improper payment rate was 10 percent in 2016, which comes to $16.2 billion.
Adding in the overpayments for standard Medicare programs, the tally for last year approached $60 billion — which is almost twice as much as the National Institutes of Health spends on medical research each year.
The low doses of arsenic similar to what many Americans consume in their drinking water are enough to develop tumors in mice, a new NIH study has found.
Researchers at the National Institutes of Health fed mice very low doses of arsenic and were surprised to find that many of them developed lung cancer, according to a study just published.
What made the results so surprising was that in previous studies, mice were fed extremely high doses of arsenic before they developed excess tumors. In the new study, mice fed lower doses of arsenic were more likely to develop tumors. The lowest dose is similar to amounts some people with private wells in the United States drink.
