Mount Sinai Hospital, the prestigious teaching hospital in New York, overcharged Medicare by almost $42 million in 2012 and 2013, according to an audit from the federal Office of Inspector General.

Most of that overpayment stemmed from Mount Sinai erroneously billing Medicare for inpatient services when they should have been billed as outpatient — a years-long problem that has pitted hospitals against auditors who review their patient medical records.

Why this matters: It's one of the largest overpayments ever found in an OIG Medicare compliance review, and Mount Sinai is fighting back. The hospital is appealing most of the overpayment amounts and disagrees with the OIG's techniques, but OIG insists the review was legit.

The big picture: The prospect of extended court fights over COVID-19-related voting changes, an absentee ballot avalanche, foreign interference and contested presidential results has prompted a hire-all-the-lawyers binge by candidates and campaigns — not just in swing states but around the country.

The three biggest anti-Joe Biden storylines in right-wing media over the last year have either fizzled or are getting less online traction than they used to, according to data from NewsWhip provided exclusively to Axios.

Why it matters: This dynamic has rendered a formidable media ecosystem less effective in boosting President Trump as we move into the heart of the 2020 campaign.

A cluster of states in the Midwest are seeing more of their coronavirus tests coming back positive — potentially an early indicator of a growing outbreak.

The state of play: A high positive rate means that a higher share of those getting tested are sick. That could be because there are more sick people, or because a state isn't doing enough testing.
